PATENT LICENSE AGREEMENT

Effective December 31, 2001, (“Effective Date”) Agere Systems Guardian Corporation (“AGERE”), a Delaware corporation having an office at 9333 S. John Young Parkway, Orlando, Florida ###-###-####, and INTRALASE CORP., a Delaware corporation, (“INTRALASE”), having an office at 3 Morgan, Irvine, California, 92618, USA, agree as follows*:

ARTICLE I

GRANTS OF LICENSES

1.01 Grant

(a) AGERE grants to INTRALASE under AGERE’s PATENTS personal, nonexclusive and non-transferable licenses to make, have made, use, lease, sell, offer to sell and import LICENSED PRODUCTS.

(b) INTRALASE grants to AGERE under INTRALASE’s PATENTS personal, nonexclusive, royalty-free and non-transferable licenses to make, have made, use, lease, sell, offer to sell and import LICENSED PRODUCTS.

1.02 Duration

All licenses granted herein under any patent shall be in effect from the Effective Date of this Agreement for the duration of the LIMITED PERIOD, unless terminated sooner pursuant to Article III.

1.03 Licensing Provisions

(a) The licenses granted herein also include licenses to (i) make, have made, use and import machines, tools, materials and other instrumentalities, insofar as such machines, tools, materials and other instrumentalities are involved in or incidental to the development, manufacture, testing or repair of LICENSED PRODUCT(S) which are or have been made, used, leased, owned, sold or imported by or for the grantee of such license; and (ii) convey to any customer of the grantee, with respect to any LICENSED PRODUCT(S) which is sold or leased by such grantee to such customer, rights to use, resell, or repair such LICENSED PRODUCT(S) as sold or leased by such grantee (whether or not as part of a larger combination); provided, however, that no rights may be conveyed to customers with respect to any invention which is directed to (1) a combination of such LICENSED PRODUCT (as sold or leased) with any other product, (2) a method or process which is other than the inherent use of such LICENSED PRODUCT itself (as sold or leased), or (3) a method or process involving the use of a LICENSED PRODUCT to manufacture (including associated testing) any other product. Notwithstanding the foregoing, licenses granted herein to INTRALASE do not include any licenses to make, use, sell, offer for sale, have made, import, or lease any products to or for any company listed on Appendix B by virtue of being a party in a patent infringement action with AGERE or any of its RELATED COMPANIES.

(b) Licenses granted herein to INTRALASE are not to be construed either (i) as consent by the grantor to any act which may be performed by the grantee, except to the extent impacted by a patent licensed herein to the grantee, or (ii) to include licenses to contributorily infringe or induce infringement under U.S. law or a foreign equivalent thereof.

(c) The grant of each license hereunder includes the right to grant sublicenses within the scope of such license to a party’s RELATED COMPANIES for so long as they remain its RELATED COMPANIES and only to the extent that such RELATED COMPANIES grant to the other party licenses of similar scope and duration as provided in this Agreement. Any such sublicense granted hereunder may be made effective retroactively, but not prior to the Effective Date hereof, nor prior to the sublicensee’s becoming a RELATED COMPANY of such party. The parties agree that if either party forms a holding company for patents licensed herein, that party shall cause such holding company to grant licenses under such patents, of the scope and duration granted herein, to the other party.

(d) The grant of each license hereunder also includes the right of a party to sublicense (commensurate with its own licenses) any business which is divested by that party or any of its RELATED COMPANIES provided that the sublicense is granted within sixty (60) days of divestiture and the divested business is itself a legal entity at the time of divestiture or within sixty (60) days thereafter. Such sublicense may continue for so long as the divested business remains a legal entity and shall extend only to the LICENSED PRODUCTS sold or furnished by the divested business prior to the divestiture and only for the patents of the non-divesting party licensed to the divesting party in this Agreement which are issued as of the date of divestiture. Furthermore, any sublicense shall not extend to the products sold or services furnished by a third party which acquires the divested business, even if they are of the same kind or similar to those of the divested business and even if made, sold or provided by the divested business. Any payment obligations of a divesting party under this Agreement shall continue in effect for all LICENSED PRODUCTS, including the LICENSED PRODUCTS of the divested business. The divested business shall be jointly and severally liable with the divesting party for royalties payable on account of the LICENSED PRODUCTS of the divested business.

1.04 Ability to Provide Licenses

(a) It is recognized that certain actions of the parties to this Agreement may limit their ability to provide licenses hereunder without constituting a breach. In particular, (i) prior to the earliest filing of a patent application disclosing an invention of a party or its RELATED COMPANY, such party or RELATED COMPANY may assign to a third party the title to patents on such invention, or (ii) prior to the Effective Date of this Agreement, a party or its RELATED COMPANY may have limited by contract its ability to provide licenses hereunder with respect to certain patents.

(b) Notwithstanding the provisions of Section 1.04(a), AGERE warrants that it has full rights to grant the licenses set forth herein with respect to U.S. Patents ###-###-####, 4597638, 5237577, and ###-###-####, and any reissues, reexaminations, or worldwide equivalents thereof.

1.05 Joint Inventions

(a) There are countries (not including the United States) which require the express consent of all inventors or their assignees to the grant of licenses or rights under patents issued in such countries for joint inventions.

2

(b) Each party shall give such consent, or shall obtain such consent from its RELATED COMPANIES, its employees or employees of any of its RELATED COMPANIES, as required to make full and effective any such licenses and rights respecting any joint invention granted to the grantee hereunder by such party and by another licensor of such grantee.

(c) Each party shall take steps which are reasonable under the circumstances to obtain from third parties whatever other consents are necessary to make full and effective such licenses and rights respecting any joint invention purported to be granted by it hereunder. If, in spite of such reasonable steps, such party is unable to obtain the requisite consents from such third parties, the resulting inability of such party to make full and effective its purported grant of such licenses and rights shall not be considered to be a breach of this Agreement.

1.06 Publicity

Nothing in this Agreement shall be construed as conferring upon either party or its RELATED COMPANIES any right to include in advertising, packaging or other commercial activities related to a LICENSED PRODUCT, any reference to the other party (or any of its RELATED COMPANIES), its trade names, trademarks or service marks in a manner which would be likely to cause confusion or to indicate that such LICENSED PRODUCT is in any way certified by the other party hereto or its RELATED COMPANIES.

1.07 Confidentiality

The terms, but not the existence, of this Agreement shall be treated as confidential information by the parties, and neither party shall disclose the terms or conditions of this Agreement to any third party (other than its RELATED COMPANIES and divested businesses licensed pursuant to this Agreement) without the prior written permission of the other party. Each party, however, shall have (i) the right to represent to third parties that such party is licensed for the products and patents as provided by this Agreement, and (ii) the right to make disclosures to the extent required by an order of court, regulation of another governmental body, or otherwise by law or by a stock exchange, provided that the party shall promptly provide written notice to the non-disclosing party of the intended disclosure and of the court order or regulation prior to such disclosure and that the party takes all reasonable steps to minimize such disclosure by, for example, obtaining a protective order and/or appropriate confidentiality provisions requiring that such information to be disclosed be used only for the purpose for which such law, order, regulation or requirement was issued. Additionally, each party may disclose this Agreement or its contents to the extent reasonably necessary, under a typical confidentiality expectations, to its accountants, attorneys, financial advisors and in connection with due diligence activities relating to the sale of the stock or a portion of the business of a party or its RELATED COMPANIES.

ROYALTY AND PAYMENTS

2.01 Royalty Payments

(a) In part payment for the grant of rights hereunder by AGERE to INTRALASE, INTRALASE shall pay to AGERE the sum of *** within thirty (30) days of EXECUTION. In no event shall such sum or any portion thereof be credited or refunded to INTRALASE.

(b) On or before thirty (30) days after EXECUTION, INTRALASE shall pay to AGERE royalties for LICENSED PRODUCTS sold or leased or otherwise put into use by INTRALASE before December 31, 2001. Such royalties shall be calculated as set forth in Section 2.01(d).

(c) For each calendar year of this Agreement starting with the year 2002, and in addition to the payment set forth in Section 2.01(a), INTRALASE shall pay to AGERE a minimum annual payment of ***, to be paid in two equal installments, each on or before January 31 and July 31 of each calendar year. Said payment shall be creditable only towards royalties that accrue during the subsequent twelve (12) month period. INTRALASE must pay this minimum payment to maintain the license granted herein, even if INTRALASE has no sales or the sales are not sufficient in any one year to generate royalties in an amount equal to the minimum annual payment. Under no circumstances shall such payment or any portion thereof be refunded to INTRALASE.

(d) INTRALASE shall pay to AGERE in United States dollars a fixed-sum of *** for each LICENSED PRODUCT sold or leased or otherwise put into use by INTRALASE or any of its RELATED COMPANIES. This royalty fee shall be applied to both (1) product sold prior to December 31, 2001 (pursuant to Section 2.01(b)), and (2) product sold after December 31, 2001.

2.02 Accrual

(a) Royalty shall accrue on any LICENSED PRODUCT upon sale, lease, or otherwise put into use and shall become payable in accordance with the provisions of Section 2.04. Obligations to pay accrued royalties shall survive termination of licenses and rights pursuant to Section 1.02 and ARTICLE III.

(b) When a company ceases to be a RELATED COMPANY of INTRALASE, royalties which have accrued with respect to any products of such company, but which have not been paid, shall become payable with INTRALASE’s next scheduled royalty payment.

(c) Notwithstanding any other provisions hereunder, royalties shall accrue and be payable only to the extent that enforcement of INTRALASE’s obligation to pay such royalties would not be prohibited by applicable law.

2.03 Records and Adjustments

(a) INTRALASE shall keep full, clear and accurate records with respect to all LICENSED PRODUCTS and shall furnish any information which AGERE may reasonably prescribe from time to time to enable AGERE to ascertain the proper royalty due hereunder on account of products sold, leased and put into use by INTRALASE or any of its RELATED COMPANIES. INTRALASE shall retain such records with respect to each LICENSED PRODUCT for at least five (5) years from the sale, lease or putting into use of such LICENSED PRODUCT. AGERE shall have the right through its accredited auditors no more than once every year to make an examination after notice of at least thirty (30) days, during normal business hours, of all records and accounts bearing upon the amount of royalty payable to it hereunder. Prompt adjustment shall be made to compensate for any errors or omissions disclosed by such examination, provided AGERE gives INTRALASE notice, in writing, of such underpayment within thirty (30) days of the completion of such audit. Such notice shall contain the report of such auditors and shall include the data which formed the

4

basis for such underpayment calculation. AGERE shall be responsible for all its costs of an audit unless the audit revealed an underpayment by INTRALASE of at least ten percent (10%) for the audited period. In such an event, INTRALASE shall be responsible for AGERE’s reasonable out-of-pocket costs for such accredited auditors to conduct the audit.

(b) Independent of any such examination, AGERE will credit to INTRALASE the amount of any overpayment of royalties made in error which is identified and fully explained in a written notice to AGERE delivered within twelve (12) months after the due date of the payment which included such alleged overpayment, provided that AGERE is able to verify, to its own satisfaction, the existence and extent of the overpayment.

(c) No refund, credit or other adjustment of royalty payments shall be made by AGERE except as provided in Sections 2.01(c) and 2.03. Rights conferred by this Section 2.03 shall not be affected by any statement appearing on any check or other document, except to the extent that any such right is expressly waived or surrendered by a party having such right and signing such statement.

2.04 Reports and Payments

(a) Within sixty (60) days after the end of each semiannual period ending on June 30th or December 31st, commencing with the semiannual period during which this Agreement becomes effective, INTRALASE shall furnish to AGERE at the address specified in Section 4.03 a statement certified by a responsible official of INTRALASE showing in a manner acceptable to AGERE the number of LICENSED PRODUCTS sold or leased or otherwise put into use by INTRALASE Section 2.01(c) and the net amount payable after application of such credit.

If no LICENSED PRODUCT has been sold the statement shall show that fact.

(b) Within such sixty (60) days INTRALASE shall pay in United States dollars to AGERE at the address specified in Section 4.03 the royalties payable in accordance with such statement. Any conversion to United States dollars shall be at the prevailing rate for bank transfers as quoted for the last day of such semiannual period by leading United States banks in New York City dealing in the foreign exchange market.
