               6.2.2 If such accounting firm concludes that additional amounts were owed during the audited period, Tracon shall pay such additional amounts within [***] after the date Cell-Matrix delivers to Tracon such accounting firm’s written report so concluding. The fees charged by such accounting firm shall be paid by Cell-Matrix; provided, however, if the audit discloses that the royalties payable by Tracon for such period are more than [***] percent ([***]%) of the royalties actually paid for such period, then Tracon shall pay the reasonable fees and expenses charged by such accounting firm.

The accounting firm shall disclose to Cell-Matrix only whether the reports are correct or not and the amount of any discrepancy. No other information shall be shared. Cell-Matrix shall treat all such financial information as Tracon’s Confidential Information

     7. PAYMENTS

          7.1 Payment Terms. Royalties shown to have accrued by each royalty report provided for under Section 6.1 above shall be due on the date such royalty report is due. Payment of royalties in whole or in part may be made in advance of such due date. All milestone payments and other payments specifically set forth in this Agreement shall be in U.S. Dollars.

          7.2 Exchange Control. If at any time legal restrictions prevent the prompt remittance of part or all royalties with respect to any country in the Territory where the Product is sold, Tracon shall have the right, in its sole discretion, to make such payments by depositing the amount thereof in local currency to Cell-Matrix’s account in a bank or other depository institution in such country. If the royalty rate specified in this Agreement should exceed the permissible rate established in any country, the royalty rate for sales in such country shall be adjusted to the highest legally permissible or government-approved rate.

          7.3 Withholding Taxes. Tracon shall be entitled to deduct the amount of any withholding taxes or value-added taxes or other similar taxes, levies or charges, other than United States taxes, payable by Tracon, its Affiliate or sublicensees, or any taxes required to be withheld or paid by Tracon, its Affiliate or sublicensees, to the extent Tracon or its sublicensees pay such taxes, charges or levies to the appropriate governmental authority on behalf of Cell-Matrix. Tracon shall use all reasonable efforts to minimize any such taxes, levies or charges required to be withheld or paid on behalf of Cell-Matrix. Tracon promptly shall deliver to Cell-Matrix proof of all such taxes, levies and other charges, together with copies of all

communications from or with such appropriate governmental authority with respect thereto. Tracon agrees to assist Cell-Matrix in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted, including using reasonable efforts to obtain, as applicable, a tax exemption certificate. If, solely as a result of any change in corporate status or location of Tracon, or permitted assignment of this Agreement, a withholding tax or value added tax, or similar tax, levy or charge becomes due on payments from Tracon to Cell-Matrix and Cell-Matrix is not able to claim a credit or reimbursement for such tax, levy or charge, in whole or in part, then Tracon shall pay [***] such amount not credited or reimbursed to Cell-Matrix upon delivery of an invoice by Cell-Matrix.

          7.4 Late Payments.

          8.1 Development Activities. Tracon shall have the responsibility for, and shall bear all of its costs for, its research, development and preclinical activities for the Product in the Territory (including the development of the manufacturing process and the manufacture of clinical trial materials) and the filing of Registrations of the Product in the Territory.

          8.2 Manufacturing and Commercialization. Tracon shall have the responsibility for, and shall bear all costs for, the manufacture of Products and, following approval to commence marketing of a Product in a country in the Territory, the commercialization activities for the Product in the Territory. Tracon shall use commercially reasonable efforts to commercialize and fill market demand for Products in each country in the Territory. To the extent required under the USC Agreement and the requirements of the Bayh-Dole Act, Products used or sold in the United States shall be manufactured substantially in the United States, unless a written waiver is obtained in advance from the relevant U.S. federal agency. Tracon shall perform, and shall ensure that its Affiliates, sublicensees, and third party contractors perform its research, development, preclinical, clinical, manufacturing and commercial activities under this Agreement in compliance with applicable laws, rules, and regulations.

          8.3 Development Milestones. Without limiting the generality of Sections 8.1 and 8.2, Tracon, its Affiliate or its sublicensee shall satisfy each of the following development milestones (each a “Development Milestone”):

                    (a) Onset of a Phase I Clinical Trial for a D93 Product by the end of [***];

                    (b) Onset of a Phase IIa Clinical Trial for [***] a D93 Product [***] within [***] following the delivery to Tracon of the final clinical study report for a Phase I Clinical Trial for the applicable Product;

                    (f) First Commercial Sale for [***] a D93 [***] within [***] following receipt of approval of a BLA for the applicable Product.

     Notwithstanding anything to the contrary, in no event shall it take Tracon more [***] following the final dosing of the final patient in each of the foregoing clinical trials in which to effect its receipt of the associated clinical study report.

     Without prejudice to any remedies as provided in this Agreement and appropriate laws, in the event Tracon or its sublicensee fails to achieve a Development Milestone, and such failure was not due to reason(s) beyond their reasonable control, Cell-Matrix shall have the right to terminate this Agreement. For the avoidance of doubt and without prejudice to other reasons that may be deemed beyond the reasonable control of Tracon or its sublicensee, should Tracon’s or its sublicensee’s failure to achieve a Development Milestone be caused by (a) [***] that Tracon or its sublicensee [***], that Tracon or its sublicensee [***] of any Product, that Tracon or its sublicensee [***], or that Tracon or its sublicensee [***] of any Product; or (b) the inability of Tracon or its sublicensee to [***] due to [***] of Tracon or its sublicensee, then such evidence presented to Cell-Matrix by Tracon or its sublicensee shall be deemed by Cell-Matrix to be beyond Tracon’s or its sublicensee’s reasonable control and Cell-Matrix shall grant Tracon or its sublicensee reasonable time extensions or milestone adjustments to the extent of any such delay (the “Excused Delay”).

     If Tracon or its sublicensee fails to achieve a Development Milestone, taking into account any Excused Delay to which Tracon or its sublicensee may be entitled, then Cell-Matrix shall grant to Tracon or its sublicensee additional time in which to achieve such Development Milestone subject to the payment to Cell-Matrix of [***] Dollars ($[***]) for each [***] extension period (each, an “Extension Period”) that is requested by Tracon or its sublicensee. In

no event shall Tracon and/or its sublicensee collectively be permitted to have more than [***] Extension Periods during the term of this Agreement for each Product. For clarity, nothing in this Section 8.3 or the making of such payments by Tracon shall relieve Tracon of its obligations under this Agreement, including its diligence obligations under this Article 8, although it shall extend the time period during which the Development Milestones of this Section 8.3 must be completed by the term of the Extension Period.

          8.4 Recalls. Each party shall promptly notify the other party in writing if it determines that any event, incident or circumstance has occurred which may result in the need for a “recall” or “market withdrawal” (as such terms are defined in 21 C.F.R. 7.3 or other similar national, state or local law or regulation) (hereinafter referred to as a “Recall”) of a Product or any lot(s) thereof. Tracon shall be responsible for determining whether and upon what terms and conditions any Product shall be Recalled or otherwise withdrawn from sale to Third Parties within any country in the Territory. Tracon shall be responsible for discussions with Competent Authorities within the applicable country regarding all aspects of the Recall decision and the execution thereof. If at any time (i) any Competent Authority in the Territory issues a request, directive or order for a Recall of a Product in the Territory or (ii) a court of competent jurisdiction orders a Recall of any Product in the Territory, then Tracon shall be responsible for implementing such Recall. The expenses arising from such Recall shall be the responsibility of Tracon.

     10. PATENTS

          10.1 Patent Prosecution and Maintenance.

               10.1.1 As between the parties, Cell-Matrix shall have the right to control, at Tracon’s cost, the preparation, filing, prosecution and maintenance of all patents and patent applications within the Cell-Matrix Patent Rights using counsel reasonably acceptable to Tracon. Cell-Matrix shall give Tracon an opportunity to review and comment on the text of each patent

application, office action (including restriction requirements) and substantive correspondence with the applicable patent office subject to this Section 10.1.1 before filing and shall supply Tracon with a copy of each patent application as filed, together with its notice of filing date and serial number. Cell-Matrix shall consider and incorporate in good faith the requests and suggestions of Tracon with respect to the foregoing and shall keep Tracon informed of progress with regard to the preparation, filing, prosecution and maintenance of the Cell-Matrix Patent Rights. Tracon shall cooperate with Cell-Matrix, execute all lawful papers and instruments and make all rightful oaths and declarations as may be necessary in the preparation, prosecution and maintenance of all patents and other filings referred to in this Section 10.1.1. If Cell-Matrix, in its sole discretion, decides to abandon the preparation, filing, prosecution or maintenance of any patent or patent application in the Cell-Matrix Patent Rights, then Cell-Matrix shall notify Tracon in writing thereof and following the date of such notice (a) Tracon shall, at its option, be responsible for and shall control, [***] the preparation, filing, prosecution and maintenance of such patents and patent applications, and (b) if Tracon does not assume such control, then Tracon shall thereafter have no license under this Agreement to such patents and patent applications.

               10.1.2 As between the parties, Tracon shall have the sole right to control, at [***] cost, the preparation, filing, prosecution and maintenance of all patents and patent applications claiming inventions or discoveries relating to the Products conceived or reduced to practice by or on behalf of Tracon in the course of developing or commercializing the Products (the “Tracon Inventions”). Tracon shall provide Cell-Matrix with annual updates regarding the discovery, conception or reduction to practice of any Tracon Inventions. Tracon shall give Cell-Matrix an opportunity to review and comment on the text of each such patent application, office action (including restriction requirements) and substantive correspondence with the applicable patent office subject to this Section 10.1.2 before filing and shall supply Tracon with a copy of each patent application as filed, together with its notice of filing date and serial number. Tracon shall consider and incorporate in good faith the requests and suggestions of Cell-Matrix with respect to the foregoing and shall keep Cell-Matrix informed of progress with regard to the preparation, filing, prosecution and maintenance of the such patents and patent applications.

          10.2 Notification of Infringement. Each party shall notify the other party of any substantial infringement in the Territory known to such party of any Cell-Matrix Patent Rights and shall provide the other party with the available evidence, if any, of such infringement.

          10.3 Enforcement of Patent Rights. Tracon, at its sole expense, shall have the right to determine the appropriate course of action to enforce Cell-Matrix Patent Rights or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce Cell-Matrix Patent Rights, to defend any declaratory judgments seeking to invalidate or hold the Cell-Matrix Patent Rights unenforceable, to control any litigation or other enforcement action and to enter into, or permit, the settlement of any such litigation, declaratory judgments or other enforcement action with respect to Cell-Matrix Patent Rights, in each case in Tracon’s own name and, if necessary for standing purposes, in the name of Cell-Matrix and shall consider, in good faith, the interests of Cell-Matrix in so doing. If Tracon does not, within [***] of receipt of notice from Cell-Matrix, abate the infringement or file suit to enforce the Cell-Matrix Patent

Rights against an infringing party in a particular country in the Territory, Cell-Matrix shall have the right to take whatever action it deems appropriate to enforce the Cell-Matrix Patent Rights; provided, however, that, within [***] after receipt of notice of Cell-Matrix’s intent to file such suit, Tracon shall have the right to jointly prosecute such suit and to fund up to [***] the costs of such suit. Notwithstanding anything to the contrary herein, the party controlling any action covered by this Section 10.3 shall not settle the action or otherwise consent to an adverse judgment in such action that diminishes the rights or interests of the non-controlling party or would impose any financial obligation on such non-controlling party without the prior written consent of the other party. All monies recovered upon the final judgment or settlement of any such suit to enforce the Cell-Matrix Patent Rights shall be [***], after reimbursement of expenses, [***].

          10.4 Cooperation. In any suit to enforce and/or defend the License Patent Rights pursuant to this Section 10, the party not in control of such suit shall, at the request and expense of the controlling party, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens, and the like.

          10.5 Consequences of Patent Challenge.

               10.5.1 Termination on Patent Challenge. Cell-Matrix shall be permitted to terminate this Agreement by written notice effective upon receipt if Tracon or its Affiliates directly, or indirectly through assistance granted to a Third Party (provided that Cell-Matrix shall provide an opportunity to Tracon to cure within [***] in the event Cell-Matrix becomes aware of such indirect assistance and if cure is feasible), commence any interference or opposition proceeding, challenge the validity or enforceability of, or oppose any extension of or the grant of a supplementary protection certificate with respect to, any patent within the Licensed Patent Rights (each such action a “Patent Challenge”).

               10.5.2 Sublicensees. Tracon shall include provisions in all agreements granting sublicenses of Tracon’s rights hereunder providing that if the sublicensee or its Affiliates undertake a Patent Challenge with respect to any patent within the Licensed Patent Rights under which the sublicensee is sublicensed, Tracon shall be permitted to terminate such sublicense agreement (provided that Tracon shall provide an opportunity to such sublicensee to cure within [***] in the event Tracon becomes aware of such indirect assistance and if cure is feasible). If a sublicensee of Tracon (or an Affiliate of such sublicensee) undertakes a Patent Challenge of any such patent under which such Sublicensee is sublicensed, then Tracon upon receipt of notice from Cell-Matrix of such Patent Challenge shall terminate the applicable sublicense agreement. If Tracon fails to so terminate such sublicense agreement within [***] of receipt of notice, Cell-Matrix may terminate this Agreement.

          10.6 Certification Under Drug Price Competition and Patent Restoration Act. Each party shall immediately give written notice to the other party of any certification of which they become aware filed pursuant to 21 U.S.C. Section 355(b)(2)(A) (or any amendment or

successor statute thereto) claiming that any Cell-Matrix Patent Rights are invalid or unenforceable, or that infringement shall not arise from the manufacture, use or sale of a product by a Third Party.

     11. TERMINATION

          11.1 Expiration. Subject to Sections 11.2 and 11.3 below, this Agreement shall expire on the expiration of the Royalty Term for all Products in all countries of the Territory.

          11.2 Termination by Tracon. Tracon may terminate this Agreement, in its sole discretion, upon [***] prior written notice to Cell-Matrix; provided, however, that Tracon shall not have the right to terminate this Agreement pursuant to this Section 11.2 prior to the earlier to occur of (a) payment of the last installment of the amount due for the deliveries actually made pursuant to Section 4, or (b) delivery to Tracon of a final clinical study report for the first Phase I Clinical Trial.

          11.3 Termination for Cause. Except as provided in Section 13, Cell-Matrix may terminate this Agreement upon or after the material breach of any provision of this Agreement by Tracon if Tracon has not cured such breach within [***] after notice thereof by Cell-Matrix (or [***] in the case of any non-payment); provided, that if the breach (other than for non-payment) is not capable of being cured in [***], then such cure period shall be extended for up to an additional [***] period provided that Tracon is using commercially reasonable efforts to cure the breach and such breach is reasonably capable of cure during such additional period.

          11.4 Effect of Expiration or Termination. Expiration or termination of this Agreement shall not relieve the parties of any obligation accruing prior to such expiration or termination, and the provisions of Sections 2.5, 3.3, 4.2, 5.1(a) and (b), 6.2, 7 (as to any amounts accrued but unpaid as of the effective date of such expiration or termination), 9, 11.4, 11.5, 12 and 14 shall survive the expiration or termination of this Agreement. If Tracon has granted a sublicense to a Third Party under the license granted to Tracon under this Agreement in accordance with Section 3.1, and provided that the Third Party sublicensee is not in breach of its agreement with Tracon or the terms of this Agreement applicable to Tracon or its sublicensees, Cell-Matrix shall grant a direct license to any such Third Party sublicensee of Tracon hereunder having the same scope as such sublicense and on terms and conditions no less favorable to such sublicensee than the terms and conditions of the applicable sublicense agreement.

          11.5 Technology Transfer Following Termination. Upon any termination of this Agreement, all of Tracon’s rights and licenses under this Agreement shall terminate, and upon written request of Cell-Matrix, Tracon shall (a) transfer to Cell-Matrix all of Tracon’s and its Affiliate’s rights (and the rights of any sublicensee subject to Sections 3.4 and 11.4), in

accordance with a mutually acceptable transition schedule, (1) copies of all data, reports and materials developed or generated by or on behalf of Tracon in the course of performing activities under this Agreement, (2) any Registrations and BLAs relating to the Products; (3) the manufacturing process for any Product and any stock of Product in the possession of Tracon or Tracon’s contract manufacturer and assign any agreement with such manufacturer to the extent specifically related to the Product and to the extent assignable (and Tracon shall use commercially reasonable efforts to seek and obtain such assignment; if such agreement is not assignable, Tracon shall use commercially reasonable efforts to provide Cell-Matrix with the benefits of such agreement by sublicense or otherwise to the extent permissible); subject to Cell-Matrix reimbursing Tracon for the reasonable time Tracon spends and expenses it incurs in relation to such transfer, and (b) in the event Tracon itself manufactures the Product as of the effective date of such termination, Tracon shall supply Product to Cell-Matrix at [***] for a period of up to [***] until Cell-Matrix has established its own source of supply; (c) upon the request of Cell-Matrix, assign any contracts with any Third Parties to the extent specifically related to the Product and to the extent assignable (and Tracon shall use commercially reasonable efforts to seek and obtain such assignment; if such agreement is not assignable, Tracon shall use commercially reasonable efforts to provide Cell-Matrix with the benefits of such agreement by sublicense or otherwise to the extent permissible); (d) grant to Cell-Matrix a worldwide, royalty free, exclusive license (with the right to grant sublicenses through multiple tiers) under any patents and patent applications owned by Tracon claiming inventions or discoveries specifically relating to the Products conceived or reduced to practice in the course of developing the Products pursuant to this Agreement, to develop, make, have made, offer for sale, sell, import and otherwise commercialize Products in the Territory for use in the Field; and (e) grant to Cell-Matrix a worldwide, license (with the right to grant sublicenses through multiple tiers) under any patents and patent applications owned by a sublicensee or to which a sublicensee has a sublicensable right claiming inventions or discoveries relating to the Products conceived or reduced to practice in the course of developing the Products pursuant to the Sublicense Agreement, to develop, make, have made, offer for sale, sell, import and otherwise commercialize Products in the Territory for use in the Field (it being understood that Cell-Matrix shall be responsible for assuming the royalty, if any, imposed by such sublicensee in connection with the foregoing license). Cell-Matrix shall reimburse Tracon’s [***] associated with performing any technology transfer pursuant to this Section 11.5. Upon the request of Cell-Matrix, Tracon shall provide technical assistance to Cell-Matrix as Cell-Matrix reasonably requests regarding the foregoing technology transfer for a reasonable period of time following such transfer. Cell-Matrix shall pay to Tracon its documented reasonable out-of-pocket costs in providing such technical assistance, and reimburse Tracon for time of personnel of Tracon engaged in the performance of such services at a reasonable cost to be agreed by the parties.

          12.1 Indemnification. Tracon shall defend, indemnify and hold Cell-Matrix and its Affiliates, and any of their directors, officers and employees, harmless from all losses, liabilities, damages and expenses (including attorneys’ fees and costs) incurred as a result of any claim, demand, action or proceeding arising out of the development, manufacture, sale or use of

any Product, any breach of this Agreement by Tracon, its Affiliates and its sublicensees, or the gross negligence or willful misconduct of Tracon in the performance of its obligations under this Agreement, except in each case to the extent arising from the gross negligence or willful misconduct of Cell-Matrix, the breach of this Agreement by Cell-Matrix or the development or manufacture of any Product by Cell-Matrix or its Affiliates prior to the date of this Agreement.

          12.2 Procedure. Cell-Matrix promptly shall notify Tracon of any liability or action in respect of which Cell-Matrix intends to claim such indemnification, and Tracon shall assume the defense thereof with counsel selected by Tracon. The indemnity in this Section 12 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of Tracon, which consent shall not be withheld unreasonably. The failure to deliver notice to Tracon within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve Tracon of any liability to Cell-Matrix under this Section 12 to the extent prejudiced, but the omission so to deliver notice to Tracon shall not relieve it of any liability that it may have to Cell-Matrix otherwise than under this Section 12. Cell-Matrix under this Section 12, its employees and agents, shall cooperate fully with Tracon and its legal representatives in the investigation and defense of any action, claim or liability covered by this indemnification.

          12.3 Insurance. Tracon shall maintain product liability insurance with respect to the research, development, manufacture and sales of Products by Tracon in such amount as Tracon customarily maintains with respect to the research, development, manufacture and sales of its similar products. Tracon shall maintain a comprehensive general liability policy of insurance (including both product liability coverage and broad form contractual liability coverage) having at least the following coverage amounts for so long as it continues to research, develop, manufacture or sell any Products, and thereafter for so long as Tracon customarily maintains insurance covering the research, development, manufacture or sale of its similar products (but in any event at [***] thereafter): (i) upon the Effective Date, single limit coverage of not less than $[***] per incident and $[***] annual aggregate; (ii) in any country where the Products, or any modification thereof, are utilized in human clinical trials, single limit coverage of not less than $[***] per incident and $[***] annual aggregate; and (iii) in any country where the Products, or any modification thereof, are administered to humans, manufactured or distributed for any purpose other than human clinical trials, single limit coverage of not less than $[***] per incident and $[***] annual aggregate.

          12.4 Guaranty. In consideration of the rights granted to Tracon under this Agreement, Paramount irrevocably and unconditionally guarantees the full and timely performance and payment by Tracon, and each of its successors and assigns, of all its obligations under this Agreement, as now or hereafter amended, restated, supplemented or otherwise modified from time to time, in favor of Cell-Matrix and each of its successors and assigns, and hereby undertakes that if Tracon, or its successors or assigns, shall in any respect fail to perform and observe all of the terms, provisions, conditions and stipulations of this Agreement (the “Obligations”), Paramount shall perform or have performed all such Obligations as required by this Agreement without any requirement that Cell-Matrix first proceed against Tracon or resort

to any other means to collect or receive the benefit of the Obligations. Notwithstanding anything to the contrary herein, Paramount’s obligations under this Section 12.4 shall expire on the earlier of the following to occur: (a) the date on which Tracon [***] of at least [***] Dollars ($[***]) as confirmed in writing by [***]; or (b) the date upon which Tracon ceases to be an Affiliate of Paramount.

     13. FORCE MAJEURE

Micromet and TRACON Pharmaceuticals Sign Exclusive Worldwide License Agreement to Develop and Commercialize D93, a Humanized Antibody for Cancer Treatment

Start of Phase 1 Clinical Trial Planned for the Second Half of This Year

San Diego, CA — March 16, 2007 — Micromet, Inc. (NASDAQ: MITI), a biopharmaceutical company focused on the development of novel and proprietary antibody-based products for cancer, inflammatory and autoimmune diseases, and TRACON Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on the development of products for cancer treatment, including agents that inhibit angiogenesis, today announced an agreement granting TRACON exclusive worldwide rights to develop and commercialize Micromet’s D93 antibody with a novel mode of action for the treatment of cancer. TRACON Pharmaceuticals was founded in 2005 by Paramount BioSciences, LLC.

“TRACON’s management team, with its specific expertise in the development of antibodies and small molecules that target angiogenesis, is an excellent partner for the development of D93 and we are looking forward to the start of clinical trials planned for the second half of this year,” said Christian Itin, President and Chief Executive Officer of Micromet, Inc.

D93 is a recombinant humanized IgG1 monoclonal antibody that inhibits angiogenesis, tumor cell growth and metastasis by targeting cleaved collagen, which is predominantly produced in the extracellular matrix of tumors. Preclinical studies indicate that D93 has the potential to treat different types of cancer as a single agent and in combination with chemotherapeutics. Because of its anti-angiogenic activity, D93 may also provide a new therapeutic approach for other diseases involving neo-vascularization such as wet age-related macular degeneration or proliferative diabetic retinopathy. In 2006, Micromet filed an IND with the Food and Drug Administration for clinical testing of D93 in patients with cancer.

“D93 is a first-in-class humanized antibody that will be developed for the treatment of a variety

of cancers to complement other currently available therapies,” said Charles P. Theuer MD, PhD, President and CEO of TRACON Pharmaceuticals.

Under the terms of the agreement, TRACON will be responsible for all development and commercial activities. TRACON plans to initiate a phase 1 clinical trial in the second half of this year. Under the terms of the agreement, TRACON will pay Micromet upfront and milestone payments of more than $100 million, if D93 is successfully developed and commercialized. In addition, Micromet will receive royalties on worldwide sales of D93.

Factors that may cause actual results to differ materially include the risk that product candidates that appeared promising in early research and clinical trials do not demonstrate safety and/or efficacy in larger-scale or later clinical trials, the risks associated with regulatory processes, the risks associated with reliance on outside financing to meet capital requirements, and the risks associated with reliance on collaborative partners for future revenues under the terms of its existing collaboration agreements, and for further pre-clinical and clinical studies, development and commercialization of product candidates. You are urged to consider statements that include the words “may,” “will,” “would,” “could,” “should,” “believes,” “estimates,” “projects,” “potential,” “expects,” “plans,” “anticipates,” “intends,” “continues,” “forecast,” “designed,” “goal,” or the negative of those words or other comparable words to be uncertain and forward-looking. These factors and others are more fully discussed in Micromet’s periodic reports and other filings with the SEC, including the “Risk Factors” sections of such reports.

Any forward-looking statements are made pursuant to Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and, as such, speak only as of the date made. Micromet and TRACON undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
