2. In addition to the covenants set forth in Article IV of the Indenture, the Notes shall be subject to the following additional covenants, and such additional covenants shall be subject to the defeasance provisions set forth in Article VIII of the Indenture:

(a) Limitation on Liens.

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur or permit to exist any Lien securing Indebtedness (the “Initial Lien”) on any Principal Property, whether owned at the Issue Date or thereafter acquired, other than Permitted Liens, without effectively providing that the Notes (together with, at the option of the Company, any other Indebtedness of the Company or any of its Subsidiaries ranking equally in right of payment with the Notes) are secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured.

Notwithstanding the foregoing, the Company or its Restricted Subsidiaries may, without equally and ratably securing the applicable series of Notes, create or incur Liens which would otherwise be subject to the restrictions set forth in the preceding paragraph, if after giving effect thereto, Aggregate Debt does not exceed the greater of (1) 25% of Consolidated Net Worth calculated as of the date of the creation or incurrence of the Lien and (2) 25% of Consolidated Net Worth calculated as of the Issue Date.

Any such Lien thereby created in favor of the Notes will be automatically and unconditionally released and discharged upon (1) the release and discharge of each Initial Lien to which it relates, or (2) any sale, exchange or transfer to any Person that is not an affiliate of the Company of the property or assets secured by such Initial Lien.

(b) Limitation on Sale and Leaseback Transactions.

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any Principal Property unless:

(1) the Company or such Restricted Subsidiary would be entitled to incur Indebtedness secured by a mortgage on the property to be leased in an amount equal to Attributable Liens with respect to such Sale/Leaseback Transactions without equally and ratably securing the Notes of such series pursuant to the first paragraph of Section 2(a) above;

(2) the net proceeds of the sale of the Principal Property to be leased are applied within 365 days of the effective date of the Sale/Leaseback Transaction to the purchase, construction, development or acquisition of another Principal Property or to the repayment of any series of Notes or Indebtedness of the Company that ranks equally with the Notes or any Indebtedness of one or more Restricted Subsidiaries; provided that in lieu of applying such amount to such retirement, the Company may deliver Notes to the Trustee for cancellation, such Notes to be credited at the cost thereof to the Company;

(3) such transaction was entered into prior to the Issue Date;

(4) such transaction involves a lease for not more than three years (or which may be terminated by the Company or a Restricted Subsidiary within a period of not more than three years); or

(5) such Sale/Leaseback Transaction with respect to any Principal Property was between only the Company and a Subsidiary of the Company or only between Subsidiaries of the Company.

2

Notwithstanding the foregoing, the Company and its Restricted Subsidiaries may enter into Sale/Leaseback Transactions, without complying with the requirements of the preceding paragraph, if, after giving effect thereto, the Aggregate Debt does not exceed the greater of (i) 25% of Consolidated Net Worth calculated as of the closing date of the Sale/Leaseback Transaction and (ii) 25% of Consolidated Net Worth calculated as of the Issue Date.

3. In addition to the definitions set forth in Article I of the Indenture, the Notes shall be interpreted in accordance with the following additional definitions, which, in the event of a conflict with the definition of terms in the Indenture, shall control:

“Aggregate Debt” means the sum of the following as of the date of determination: (1) the aggregate principal amount of the Company’s and its Restricted Subsidiaries’ Indebtedness incurred after the Issue Date and secured by Liens not permitted by the first paragraph under Section 2(a) above and (2) the Company’s and its Restricted Subsidiaries’ Attributable Liens in respect of Sale/Leaseback Transactions entered into after the Issue Date pursuant to the second paragraph of Section 2(b) above.

“Attributable Liens” means in connection with a Sale/Leaseback Transaction the lesser of: (1) the fair market value of the assets subject to such transaction, as determined in good faith by the Board of Directors; and (2) the present value (discounted at a rate of 7.5% per annum compounded monthly) of the obligations of the lessee for rental payments during the term of the related lease.

“Capital Lease” means any Indebtedness represented by a lease obligation of a Person incurred with respect to real property or equipment acquired or leased by such Person and used in its business that is required to be recorded as a capital lease in accordance with GAAP.

(5) (i) Liens given to secure the payment of the purchase price incurred in connection with the acquisition (including acquisition through merger or consolidation) of any Principal Property, including Capital Lease transactions in connection with any such acquisition, and (ii) Liens existing on any Principal Property at the time of acquisition thereof or at the time of acquisition by the Company of any Person then owning such property whether or not such existing Liens were given to secure the

4

payment of the purchase price of the property to which they attach; provided that with respect to clause (i), the Liens shall be given within 12 months after such acquisition and shall attach solely to the Principal Property acquired or purchased and any improvements then or thereafter placed thereon and any proceeds thereof;

“Principal Property” means the Company’s principal offices in San Diego, California, and each manufacturing and research and development facility (including associated office facilities) located within the territorial limits of the States of the United States of America owned by the Company or any of its Restricted Subsidiaries, except such as the Company’s Board of Directors by resolution determines in good faith (taking into account, among other things, the importance of such property to the business, financial condition and earnings of the Company and its Restricted Subsidiaries taken as a whole) not to be of material importance to the business of the Company and its Restricted Subsidiaries, taken as a whole.

5
