In the opinion of Orrick, Herrington & Sutcliffe LLP, Special Counsel to the County, based upon an analysis of existing laws, regulations, rulings and court decisions, and assuming, among other matters, the accuracy of certain representations and compliance with certain covenants, the interest component of the Installment Payments to be paid by the County under the Purchase Agreement and received by the Beneficial Owners is excluded from gross income for federal income tax purposes under Section 103 of the Internal Revenue Code of 1986 and is exempt from State of California personal income taxes. In the further opinion of Special Counsel, such interest component is not a specific preference item for purposes of the federal individual or corporate alternative minimum taxes. Special Counsel expresses no opinion regarding any other tax consequences related to the ownership or disposition of, or the accrual or receipt of interest with respect to, the Certificates, including whether the interest component of the Installment Payments to be paid by the County under the Purchase Agreement and received by the Beneficial Owners is included in adjusted current earnings when calculating corporate alternative minimum taxable income.

Gross Revenue Fund Pledge

As provided in the 2005 Loan Agreement, the Corporation has pledged, and to the extentpermitted by law, granted a security interest to the 2005 Trustee (as assignee of the Authority) in all of itsGross Revenues and the proceeds thereof, to secure the obligations of the Corporation under the 2005Loan Agreement. “Gross Revenues” is defined under the 2005 Loan Agreement to mean all moneys,

The Corporation has already included, and pursuant tothe 2005 Loan Agreement may in the future incur, other indebtedness which has a claim on GrossRevenues, thus reducing the amount of Gross Revenues available for the payment of the Certificates.

In the event of a default by the Corporation under the Sale Agreement, control of the GrossRevenues will be transferred to the Trustee, and the Trustee will be obligated use such funds to make thePurchase Payments and any parity payments including, without limitation, the loan payments to be madeby the Corporation to the Authority pursuant to the 2005 Loan Agreement, and any other paymentsrequired to be made by the Corporation under the Sale Agreement and 2005 Loan Agreement.

The Trust Agreement provides thatsaid pledge will constitute a lien on and security interest in such assets and will attach, be perfected andbe valid and binding from and after delivery by the Trustee of the Certificates, without any physicaldelivery thereof or further act. Pursuant to the Trust Agreement, the County transfers in trust, grants a

11

security interest in and assigns to the Trustee, for the benefit of the Holders from time to time of theCertificates, all of its interests in the Revenues and other assets so pledged and all of the right, title andinterest of the County in the Sale Agreement (except Supplemental Payments, any rights of the County toindemnification paid by the Corporation and the obligation of the Corporation to make deposits to theRebate Fund). The Trustee is entitled to and will collect and receive all of the Revenues.

In the event that the Corporation is delinquent for more than one (1) Business Day in the paymentor required prepayment of any Purchase Payment or any payment with respect to Parity Debt, the Trusteeis required to notify the Corporation, the County and the Depository Bank(s) of such delinquency, and,unless such Purchase Payment or payment with respect to Parity Debt is paid within five (5) days afterreceipt of such notice, the Corporation is required to cause the Depository Bank(s) to transfer the GrossRevenue Fund to the name and credit of the Trustee, as assignee of the County. All Gross Revenues willcontinue to be deposited in the Gross Revenue Fund until the amounts on deposit in such fund aresufficient to pay in full, or have been used to pay in full, all Purchase Payments in default and paymentsrequired with respect to Parity Debt in default and until all other Sale Agreement Defaults and events ofdefault with respect to Parity Debt known to the Trustee have been made good or cured to the satisfactionof the Trustee or provision deemed by the Trustee to be adequate has been made therefor whereupon theGross Revenue Fund (except for Gross Revenues required to make such payments or cure such defaults)will be transferred by the Depository Bank(s) automatically back to the name and credit of theCorporation. During any period that the Gross Revenue Fund is held in the name and to the credit of theTrustee, the Trustee is required to use and withdraw from time to time amounts in such fund to makePurchase Payments, Supplemental Payments and the other payments required of the Corporation underthe Sale Agreement or with respect to any Parity Debt as such payments become due (whether bymaturity, prepayment, acceleration or otherwise) and, if such amounts are not sufficient to pay in full allsuch payments due on any date, then to the payment of Purchase Payments and debt service on suchParity Debt, ratably according to the amounts due respectively for Purchase Payments and such debtservice, without any discrimination or preference, and to such other payments in the order which theTrustee, in sole its discretion, determines to be in the best interests of the Holders of the Certificates andsuch Parity Debt, without discrimination or preference.

RISK FACTORS

This Official Statement discusses many matters, any one of which may have an impact on thesecurity for the Certificates, the ability of the Corporation to make timely Purchase Payments to theCounty under the Sale Agreement, subsequent ratings on the Certificates, or the market value thereof. Aninvestor must therefore read the entire Official Statement to judge the risks inherent in an investment inthe Certificates. This section highlights certain risks inherent in the transaction, but is not intended to be,and does not purport to be, a complete list or discussion of the risks associated with this transaction. Thefollowing factors, along with all other information in this Official Statement in its entirety, should beconsidered by potential investors in evaluating the Certificates.

Limited Obligation for Certificates

The Certificates are payable solely from Installment Payments to be made by the County underthe Purchase Agreement which Installment Payments are payable solely from Revenues derived primarilyfrom Purchase Payments made by the Corporation to the County under the Sale Agreement and not fromany other fund or source. The Corporation substantially relies on grants and donations from public andprivate donors and on investment earnings from its endowments for its operating expenses and its debtservice payments. No representation or assurance can be made or given that sufficient revenues will begenerated in the future by the Corporation to make the Purchase Payments necessary to pay the principal,premium, if any, and interest components with respect to the Certificates. The payment of the PurchasePayments is a general obligation of the Corporation, secured by a pledge of Gross Revenues. The SaleAgreement allows the Corporation to provide its assets as collateral security for future borrowings. See“SECURITY FOR THE CERTIFICATES.” See APPENDIX A – “INFORMATION CONCERNINGTHE CORPORATION” and the Corporation’s audited financial statements for its Fiscal Year ended June30, 2009 attached hereto as Appendix B.

Future revenues and expenses of the Corporation will be affected by events and conditionsrelating generally to, among other things: the extent of funding through National Institute of Health(“NIH”) research grants; research grants from other sources; the Corporation’s ability to maintain orincrease investment returns and to raise funds, to maintain and solicit donations and to develop privatelysponsored research and other programs; the success of its patent and licensing program; the continuedexcellence of its research personnel and the relevance of their research programs; management

14

capabilities; economic developments; and the Corporation’s ability to control expenses and maintain goodrelations with the NIH and private sponsors of research, competition, costs and governmental legislationand regulation. Research statutes and regulations will change, funded researchers may leave or join theCorporation and unanticipated events and circumstances may occur, which could cause materialvariations in future revenues. These factors, among others, may affect, in a positive or negative manner,the level of the Corporation’s revenues and its financial condition. See Appendix A for further discussionof the sources of revenues and funding of the Corporation. There can be no assurance that the financialcondition of the Corporation will not be adversely affected, and there can be no guaranty there will besufficient revenue to make payments with respect to the Certificates. See APPENDIX A –‘INFORMATION CONCERNING THE CORPORATION – FINANCIAL OPERATIONS” herein for adiscussion of process through which the Corporation receives and administers research grants, and theimpact on such grants of a lead investigator leaving the Corporation.

With respect to the financial condition of the Corporation for the year ended June 30, 2009, seethe audited financial statements of the Corporation attached hereto as Appendix B.

Maintenance of Tax-Exempt Status

Federal Income Tax Exemption. The tax-exempt status of the Certificates presently depends uponthe Corporation’s maintenance of its status as an organization described in the Code. The maintenance ofsuch status is contingent on compliance with general rules promulgated in the Code and relatedregulations regarding the organization and operation of tax-exempt entities, including its operation forcharitable purposes and its avoidance of transactions which may cause its assets to inure to the benefit ofprivate individuals. As these general principles were developed primarily for public charities which donot conduct large-scale technical operations and business activities, they often do not directly address themyriad of operations and transactions entered into by a modern research organization. Although specificactivities of such organizations have been the subject of interpretations by the Internal Revenue Service(“IRS”) in the form of Private Letter Rulings, many activities or categories of activities have not beenaddressed in any official opinion, interpretation, or policy of the IRS.

In recent years, the IRS has increased the frequency and scope of its audit of tax-exemptorganizations. The primary penalty available to the IRS under the Code is revocation of tax-exemptstatus. Following suggestions from the United States Treasury, Congress adopted sanctions which are lessonerous than full revocation of tax-exempt status. While the IRS has not frequently revoked the Section501(c)(3) tax-exempt status of nonprofit corporations in the past, there can be no assurance that it will notdo so in the future or that it will not direct enforcement activities at the Corporation. It is possible that lossof tax-exempt status by the Corporation could result in loss of tax exemption of the Certificates and ofother tax-exempt debt of the Corporation, and defaults in covenants regarding the Certificates and otherrelated tax-exempt debt would likely be triggered. Such an event could have material adverseconsequences on the financial condition of the Corporation taken as a whole.

The IRS has additional powers to use against nonprofit organizations that violate federal tax laws.The additional authority for dealing with 501(c)(3) organizations comes in the form of an “intermediatesanction,” which will allow the IRS to impose penalties on 501(c)(3) corporations without resorting to therevocation of the tax exempt status of the nonprofit entity and thus its bonds or certificates ofparticipation. Under this law, the IRS can impose an excise tax to recover any “excess profits” 501(c)(3)corporations earn from the transfer of its assets to other, noncharitable parties.

State Income Tax Exemption and Local Property Tax Exemption. In the event of the loss by theCorporation of federal tax exemption, such a loss might trigger a challenge to the State tax exemption ofthe Corporation. Depending on circumstances, such an event could be adverse and material.

15

In recent years, state, county, and local taxing authorities have been undertaking audits andreviews of the operations of tax-exempt organizations with respect to its real property tax exemption. TheThe Facilities and the Real Property are exempt from real property taxation. Although the real propertytax exemption with respect to the facilities of the Corporation (including the proposed capital projects) isnot, to the knowledge of management of the Corporation, under challenge by such authorities, aninvestigation or audit could lead to a challenge that, if successful, could adversely affect the real propertytax exemption with respect to the facilities of the Corporation.

Unrelated Business Income. In recent years, the IRS and state, county and local taxing authoritieshave been undertaking audits and reviews of the operations of tax-exempt organizations with respect to itsexempt activities and the generation of unrelated taxable business income (“UBI”). In some cases, thetax-exempt status of the organizations has been questioned. The Corporation participates in activitieswhich may generate UBI. The Corporation has historically not received any UBI, and managementbelieves it has properly accounted for its revenues; nevertheless, an investigation or audit could lead to achallenge which could ultimately affect the tax-exempt status of the Corporation as well as the exclusionfrom gross income for federal income tax purposes of the interest payable with respect to the Certificates.

Environmental Laws and Regulations

Biological research facilities are subject to a wide variety of federal, state and localenvironmental and occupational health and safety laws and regulations which address, among otherthings, operations or facilities and properties owned or operated by such organizations. Among the typesof regulatory requirements faced by research facilities are air and water quality control requirements,waste management requirements, specific regulatory requirements applicable to asbestos, polychlorinatedbiphenyls and radioactive substances, requirements for providing notice to employees and members of thepublic about hazardous materials and wastes, and other requirements.

Typical research operations include, but are not limited to, in various combinations, the handling,use, treatment, storage, transportation, disposal and/or discharge of hazardous, infectious, toxic,radioactive and flammable materials, wastes, pollutants or contaminants. As such, research operations areparticularly susceptible to the practical, financial and legal risks associated with the obligations imposedby applicable environmental laws and regulations. Such risks may result in damage to individuals,property or the environment; may interrupt operations and/or increase their cost; may result in legalliability, damages, injunctions or fines; may result in investigations, administrative proceedings, civillitigation, criminal prosecution, penalties or other governmental agency actions; and may not be coveredby insurance. There can be no assurance that the Corporation will not encounter such risks in the future,and such risks may result in material adverse consequences to the operations or financial condition of theCorporation. In addition, in their role as owner of properties or facilities, biological researchorganizations may be subject to liability for investigating and remedying contamination caused by anyhazardous substances which have come to be located on the property, including contamination caused byany such substances that may have migrated off of the property.

At the present time, management of the Corporation is not aware of any pending or threatenedclaim, investigation or enforcement action regarding such environmental issues, or any instance ofcontamination, which, if determined adversely to the Corporation would have material adverseconsequences to the Corporation.

Factors That Could Affect the Enforceability of the Sale Agreement

The legal right and practical ability of the Trustee to enforce its rights and remedies against theCorporation under the Sale Agreement and related documents may be limited by laws relating to

16

bankruptcy, insolvency, reorganization, fraudulent conveyance or moratorium and by other similar lawsaffecting creditors’ rights. In addition, the Trustee’s ability to enforce such terms will depend upon theexercise of various remedies specified by such documents which may in many instances require judicialactions that are often subject to discretion and delay or that otherwise may not be readily available or maybe limited.

Bankruptcy

The ability of the Trustee to enforce the obligations of the Corporation under the Sale Agreementmay be limited by laws relating to bankruptcy, insolvency, reorganization or moratorium and by othersimilar laws affecting creditors rights, including equitable principles. In addition, the Trustee’s ability toenforce such agreements will depend upon the exercise of various remedies specified by such documentswhich may in many instances require judicial actions that are often subject to discretion, delay andsubstantial costs or that otherwise may not be readily available or may be limited.

The various legal opinions to be delivered concurrently with the delivery of the Certificates willbe qualified as to the enforceability of the various legal instruments by limitations imposed by State andfederal laws, rulings and decisions affecting remedies, and by bankruptcy, reorganization or other laws ofgeneral application affecting the enforcement of creditors’ rights, including equitable principles.

In the event of bankruptcy of the Corporation, the rights and remedies of the Certificate Holdersare subject to various provisions of the federal Bankruptcy Code. If the Corporation were to file a petitionin bankruptcy, payments made by the Corporation during the 90-day (or possibly one-year if related to aninsider, as provided as in the Bankruptcy Code) period immediately preceding the filing of such petitionmay be avoidable as preferential transfers to the extent such payments allow the recipients thereof toreceive more than they would have received in the event of the Corporation’s liquidation. Securityinterests and other liens granted to the Trustee and perfected during such preference period may also beavoided as preferential transfers to the extent such security interest or other lien secures obligations thatarose prior to the date of such perfection. Such a bankruptcy filing would operate as an automatic stay ofthe commencement or continuation of any judicial or other proceeding against the Corporation and itsproperty and as an automatic stay of any act or proceeding to enforce a lien upon or to otherwise exercisecontrol over its property as well as various other actions to enforce, maintain or enhance the rights of theTrustee. If the bankruptcy court so ordered, the property of the Corporation could be used for the financialrehabilitation of the Corporation, despite any security interest of the Trustee therein. The rights of theTrustee to enforce its security interest could be delayed during the pendency of the rehabilitationproceeding.

The Corporation could file a plan for the adjustment of its debts in any such proceeding whichcould include provisions modifying or altering the rights of creditors generally, or any class of them,secured or unsecured. The plan, when confirmed by a court, binds all creditors who had notice orknowledge of the plan and, with certain exceptions, discharges all claims against the debtor to the extentprovided for in the plan. No plan may be confirmed unless certain conditions are met, among which arethat the plan is feasible and has been accepted by each class of claims impaired thereunder. Each class ofclaims has accepted the plan if at least two-thirds in dollar amount and more than one-half in number ofthe class cast votes in its favor. Even if the plan is not so accepted, it may be confirmed if the court findsthat the plan is fair and equitable with respect to each class of non-accepting creditors impairedthereunder and does not discriminate unfairly.

The Trustee’s security interest in the Revenues under the Trust Agreement may be subordinatedto the interest and claims of others in several instances. Some examples of cases of subordination of priorclaims are (i) statutory liens, (ii) rights arising in favor of the United States of America or any agency

17

thereof, (iii) present or future prohibitions against assignment in any statutes or regulations, (iv)constructive trusts, equitable liens or other rights impressed or conferred by any state or federal court inthe exercise of its equitable jurisdiction, (v) federal or state bankruptcy or insolvency laws that may affectthe enforceability of the Sale Agreement or pledge of Revenues, (vi) rights of third parties in Revenuesconverted to cash and not in the possession of the Trustee or a depository bank, (vii) commingling ofproceeds of Revenues with other moneys of the Corporation not subject to the security interest in theRevenues; and (viii) claims that might arise if appropriate financing or continuation statements are notfiled in accordance with the California Uniform Commercial Code as from time to time in effect.

Insurance

The Corporation purchases insurance for employee medical benefits and workers’ compensationbenefits from commercial insurers licensed to sell insurance in the State of California. The Corporationalso purchases insurance covering liability and physical damage to the Corporation’s facilities subject tocustomary deductibles. See APPENDIX A – “INFORMATION CONCERNING THE CORPORATION– OTHER MATTERS – Insurance” for a discussion of the Corporation’s current insurance coverage.

Seismic Hazard

The facilities of the Corporation are located in a seismically active region of southern California.The occurrence of severe seismic activity in the area could result in substantial damage to the facilities ofthe Corporation and could have a material, adverse impact on the Corporation’s finances. The SaleAgreement does not require the Corporation to maintain earthquake insurance for its facilities. Forinformation concerning insurance currently maintained by the Corporation, see APPENDIX A –“INFORMATION CONCERNING THE CORPORATION” attached hereto.

Investment of Funds Risk

All funds and accounts held under the Trust Agreement are required to be invested in InvestmentSecurities as provided under the Trust Agreement. See Appendix C attached hereto for a summary of thedefinition of “Investment Securities.” See the financial statements of the Corporation attached asAppendix B for a summary of the investments of the Corporation as of the date of such financialstatements. All investments, including the Investment Securities and other investments made by theCorporation, contain a certain degree of risk. Such risks include, but are not limited to, a lower rate ofreturn than expected, loss of market value and loss or delayed receipt of principal. The occurrence ofthese events with respect to amounts held under the Trust Agreement or by the Corporation could have amaterial adverse effect on the security of the Certificates.

ABSENCE OF MATERIAL LITIGATION

The Corporation. There is no controversy or litigation of any nature now pending against theCorporation, or to the knowledge of its officers threatened, restraining or enjoining the execution, sale anddelivery of the Certificates, in any way contesting or affecting the validity of the Certificates, in any waycontesting the corporate existence or powers of the Corporation, or challenging any proceedings of theCorporation taken concerning the execution, sale and delivery thereof or the pledge or application of anymoneys or security provided for the payment of the Certificates which, if determined adversely to theCorporation, might materially adversely affect the consummation of the transactions contemplated by thisOfficial Statement or the financial condition, assets or properties of the Corporation. See also,APPENDIX A – “INFORMATION CONCERNING THE CORPORATION – OTHER MATTERS -Litigation.”

18

The County. To the knowledge of the County, there is no controversy or litigation of any naturenow pending against the County, threatened, restraining or enjoining the execution, sale and delivery ofthe Certificates, or in any way contesting or affecting the validity of the Certificates, any proceedings ofthe County taken concerning the execution, sale and delivery thereof, the pledge or application of anymoneys or security provided for the payment of the Certificates, or the existence or powers of the Countyrelating to the execution, sale or delivery of the Certificates.

VERIFICATION

Upon delivery of the Certificates, Causey Demgen & Moore Inc., a firm of independent publicaccountants, will deliver a report on the mathematical accuracy of certain computations based uponcertain information and assertions provided to them by the Underwriter relating to (a) the adequacy of thematuring principal and interest on the federal securities in the Escrow Fund to pay all of the principal,interest and prepayment premium on the Refunded Certificates and (b) the computations of yield of theCertificates and the federal securities in the Escrow Fund which support Special Counsel’s opinion thatthe interest with respect to the Certificates is excluded from gross income for federal income taxpurposes.

TAXMATTERS

In the opinion of Orrick, Herrington & Sutcliffe LLP, Special Counsel to the County (“SpecialCounsel”), based upon an analysis of existing laws, regulations, rulings and court decisions, andassuming, among other matters, the accuracy of certain representations and compliance with certaincovenants, the interest component of the Installment Payments to be paid by the County under thePurchase Agreement and received by the Beneficial Owners of the Certificates is excluded from grossincome for federal income tax purposes under Section 103 of the Internal Revenue Code of 1986 (the“Code”) and is exempt from State of California personal income taxes. Special Counsel is of the furtheropinion that such interest component evidenced by the Certificates is not a specific preference item forpurposes of the federal individual or corporate alternative minimum taxes. Special Counsel expresses noopinion on whether the interest component of the Installment Payments to be paid by the County underthe Purchase Agreement and received by the Beneficial Owners of the Certificates is included in adjustedcurrent earnings when calculating corporate alternative minimum taxable income. A complete copy ofthe proposed form of opinion of Special Counsel is set forth in Appendix E hereto.

To the extent the issue price of any maturity of the Certificates is less than the amount to be paidat maturity of such Certificates (excluding amounts stated to be interest and payable at least annually overthe term of such Certificates), the difference constitutes “original issue discount,” the accrual of which, tothe extent properly allocable to each Beneficial Owner thereof, is treated as interest evidenced by theCertificates which is excluded from gross income for federal income tax purposes and State of Californiapersonal income taxes. For this purpose, the issue price of a particular maturity of the Certificates is thefirst price at which a substantial amount of such maturity of the Certificates is sold to the public(excluding bond houses, brokers, or similar persons or organizations acting in the capacity ofunderwriters, placement agents or wholesalers). The original issue discount with respect to any maturityof the Certificates accrues daily over the term to maturity of the Certificates on the basis of a constantinterest rate compounded semiannually (with straight-line interpolations between compounding dates).The accruing original issue discount is added to the adjusted basis of such Certificates to determinetaxable gain or loss upon disposition (including sale, prepayment, or payment on maturity) of suchCertificates. Beneficial Owners should consult their own tax advisors with respect to the taxconsequences of ownership of Certificates with original issue discount, including the treatment ofBeneficial Owners who do not purchase such Certificates in the original offering to the public at the firstprice at which a substantial amount of such Certificates is sold to the public.

19

Certificates purchased, whether at original execution and delivery or otherwise, for an amounthigher than their principal evidenced thereby payable at maturity (or, in some cases, at their earlierprepayment date) (“Premium Certificates”) will be treated as having amortizable premium. No deductionis allowable for the amortizable premium in the case of obligations, like those evidenced by the PremiumCertificates, the interest with respect to which is excluded from gross income for federal income taxpurposes. However, the amount of tax-exempt interest received, and a Beneficial Owner’s basis in aPremium Certificate, will be reduced by the amount of amortizable premium properly allocable to suchBeneficial Owner. Beneficial Owners of Premium Certificates should consult their own tax advisors withrespect to the proper treatment of amortizable premium in their particular circumstances.

The Code imposes various restrictions, conditions and requirements relating to the exclusion fromgross income for federal income tax purposes of interest on obligations such as the Certificates. TheCounty and the Corporation have made certain representations and covenanted to comply with certainrestrictions, conditions and requirements designed to ensure that the interest portion of the InstallmentPayments received by the Beneficial Owners will not be included in federal gross income. Inaccuracy ofthese representations or failure to comply with these covenants may result in such interest componentbeing included in gross income for federal income tax purposes, possibly from the date of originalexecution and delivery of the Certificates. The opinion of Special Counsel assumes the accuracy of theserepresentations and compliance with these covenants. Special Counsel has not undertaken to determine(or to inform any person) whether any actions taken (or not taken), or events occurring (or not occurring),or any other matters coming to Special Counsel’s attention after the date of execution and delivery of theCertificates may adversely affect the value of, or the tax status of the interest portion of the InstallmentPayments evidenced by, the Certificates.

In addition, Special Counsel has relied, among other things, on the opinion of Allen Matkins LeckGamble Mallory & Natsis LLP, Counsel to the Corporation, regarding the current qualification of theCorporation as an organization described in Section 501(c)(3) of the Code and the intended operation ofthe facilities to be financed by the Certificates as substantially related to the Corporation’s charitablepurpose under Section 513(a) of the Code. Such opinion is subject to a number of qualifications andlimitations. Furthermore, Counsel to the Corporation cannot give and has not given any opinion orassurance about the future activities of the Corporation, or about the effect of future changes in the Code,the applicable regulations, the interpretation thereof or changes in enforcement thereof by the IRS.Failure of the Corporation to be organized and operated in accordance with the IRS’s requirements for themaintenance of its status as an organization described in Section 501(c)(3) of the Code, or to operate thefacilities financed by the Certificates in a manner that is substantially related to the Corporation’scharitable purpose under Section 513(a) of the Code, may result in the interest portion of the InstallmentPayments to be paid by the County under the Purchase Agreement and received by the Beneficial Ownersbeing included in federal gross income, possibly from the date of the original execution and delivery ofthe Certificates.

Although Special Counsel is of the opinion that the interest component of the InstallmentPayments to be paid by the County and received by the Beneficial Owners is excluded from gross incomefor federal income tax purposes and is exempt from State of California personal income taxes, theownership or disposition of, or the accrual or receipt of interest evidenced by, the Certificates mayotherwise affect a Beneficial Owners’ federal, state or local tax liability. The nature and extent of theseother tax consequences depends upon the Beneficial Owner’s particular tax status and other items ofincome or deduction. Special Counsel expresses no opinion regarding any such other tax consequences.

Future legislative proposals, if enacted into law, clarification of the Code or court decisions maycause the interest component of the Installment Payments to be paid by the County and received by theBeneficial Owners to be subject, directly or indirectly, to federal income taxation or to be subject to

20

exempted from state income taxation otherwise prevent Beneficial Owners from realizing the full currentbenefit of the tax status of such interest component. The introduction or enactment of any such futurelegislative proposals, clarification of the Code or court decisions may also affect the market price for, ormarketability of, the Certificates. Prospective purchasers of the Certificates should consult their own taxadvisors regarding any pending or proposed federal or state tax legislation, regulations or litigation, as towhich Special Counsel expresses no opinion.

The opinion of Special Counsel is based on current legal authority, covers certain matters notdirectly addressed by such authorities, and represents Special Counsel’s judgment as to the propertreatment of the Certificates for federal income tax purposes. It is not binding on the IRS or the courts.Furthermore, Special Counsel cannot give and has not given any opinion or assurance about the futureactivities of the County or the Corporation, or about the effect of future changes in the Code, theapplicable regulations, the interpretation thereof or the enforcement thereof by the IRS. The County andthe Corporation have covenanted, however, to comply with the requirements of the Code.

Special Counsel’s engagement with respect to the Certificates ends with the execution anddelivery of the Certificates, and, unless separately engaged, Special Counsel is not obligated to defend theCounty, the Corporation or the Beneficial Owners regarding the tax-exempt status of the Certificates inthe event of an audit examination by the IRS. Under current procedures, parties other than the County,the Corporation and their appointed counsel, including the Beneficial Owners, would have little, if any,right to participate in the audit examination process. Moreover, because achieving judicial review inconnection with an audit examination of tax-exempt bonds is difficult, obtaining an independent reviewof IRS positions with which the County or the Corporation legitimately disagrees, may not be practicable.Any action of the IRS, including but not limited to selection of the Certificates for audit, or the course orresult of such audit, or an audit of obligations presenting similar tax issues may affect the market pricefor, or the marketability of, the Certificates, and may cause the County, the Corporation or the BeneficialOwners to incur significant expense.

CONTINUING DISCLOSURE

The County has determined that no financial or operating data concerning the County is materialto an evaluation of the offering of the Certificates or to any decision to purchase, hold or sell theCertificates, and the County will not provide any such information.

HISTORY AND BACKGROUND

The Salk Institute for Biological Studies (“Salk” or the "Institute"), a California non-profit publicbenefit organization, is one of the world's pre-eminent basic research institutions, whereinternationally renowned faculty probe fundamental life science questions in a unique,collaborative, and creative environment. Since 1960, when Dr. Jonas Salk, the developer of thepolio vaccine, founded his world-renowned Institute, scientists at the Institute have activelypursued innovative basic research that has led to a string of seminal papers with enormousimpact toward a better understanding of human health and disease. Focused both on discoveryand on mentoring future generations of researchers, Salk scientists have made groundbreakingcontributions to the understanding of cancer, aging, Alzheimer's disease, diabetes, and infectiousdiseases by studying neuroscience, genetics, cell and plant biology, and related disciplines.

Dr. Salk’s goal was to establish an institute that would explore questions about the basicprinciples of life. He wanted to make it possible for biologists and others to work together in acollaborative environment that would encourage them to consider the wider implications of theirdiscoveries for the future of humanity. In December 1959, Dr. Salk and architect Louis Kahnbegan a unique partnership to design the Institute, which Dr. Salk envisioned as “a facilityworthy of a visit by Picasso”. Kahn, a devoted artist before he became an architect, was able torespond to this challenge. In 1960, the City of San Diego granted Dr. Salk a gift of land on theTorrey Pines Mesa overlooking the Pacific Ocean.

When the first laboratory was opened in 1963, there were five senior scientists and their researchteams. This distinguished group of fellows formed members of Salk’s first faculty group and inaddition to Jonas Salk included Jacob Bronowski, Melvin Cohn, Renato Dulbecco, EdwinLennox, and Leslie Orgel. The first Non-Resident Fellows (appointed scientists from otherinstitutions) selected were Francis Crick, Salvador Luria, Jacques Monod, Leo Szilard, andWarren Weaver. During the next few years, as the Institute expanded, resident fellows (nowgenerally regarded as professors) and Non-Resident Fellows together advised Dr. Salk aboutfuture scientific directions. The organization of the Institute has evolved with time to its presentstructure which consists of a Board of Trustees (the “Board”), a President (the “President”), anAcademic Council, and a Chair of the Faculty.

The Salk Institute’s major areas of study are focused on molecular biology and genetics, theneurosciences, plant biology, and infectious disease. Today, the Salk Institute conducts itsbiomedical research in 24 laboratories. At present, the faculty numbers 60, with a scientific staffof more than 850. This latter group consists of visiting scientists, some 285 postdoctoral trainees,approximately 130 graduate and rotation students, and more than 90 undergraduate students.Although not a degree-granting institution, the Salk has trained more than 2,300 scientists; manyhave gone on to positions of leadership in other prominent research centers worldwide. Five ofthe scientists trained at the Institute have won the Nobel Prize. Three of the Institute’s currentresident faculty members and four Non-Resident Fellows are Nobel Laureates.

The Institute has been supported over the years by funds awarded to its faculty in the form ofresearch grants, most from the National Institutes of Health (“NIH”), and from privatefoundations and individuals. Especially important has been the continued support of the March

A-3

of Dimes Foundation which, in addition to funds for the original structure, has contributedsignificantly every year to the Institute’s financial needs.

GOVERNANCE AND MANAGEMENT

Governance of the Institute is vested in the Institute’s Board of Trustees (the “Board”) whichprovides policy and management oversight. The Non-Resident Fellows provide the Board, theInstitute’s President (the “President”), and faculty with insight into long-range scientific programplanning and direction.

Board of TrusteesThe Board of Trustees is composed of proven leaders from the world’s business and non-profitcommunities who bring a range of skills and perspectives to the Institute. They are committed toscience, innovation and high-quality research, and support the Institute’s mission. Trustees arecharged with monitoring Institute operations to ensure the organization fulfills its scientific andtraining efforts while operating in a financially responsible manner.

Trustees are elected by the Board to serve three-year terms, staggered to ensure organizationalcontinuity. Elected Trustees may not serve more than three consecutive full terms, but shall beeligible to serve again for a single three-year term after an absence of at least one year.

The Board is currently chaired by Irwin Mark Jacobs, Sc.D. Dr. Jacobs has been Chairman of theInstitute’s Board since November 2006. Dr. Jacobs is co-founder (1985) and director ofQUALCOMM Incorporated, previously serving as its chairman and chief executive officer. Heserved as chief executive officer of QUALCOMM until July 2005 and led the successfuldevelopment and commercialization of Code Division Multiple Access (“CDMA”) technologyfor cellular phones. Dr. Jacobs holds 13 CDMA patents. In 1969, Dr. Jacobs co-foundedLINKABIT Corporation. The company merged with M/A-Com in 1980 and he remained asexecutive vice president of M/A-Com until 1985. Over 35 San Diego companies trace their rootsto LINKABIT. Dr. Jacobs was an assistant and associate professor of electrical engineering atMassachusetts Institute of Technology (“MIT”) from 1959 to 1966 before moving to San Diegoin 1966 to help establish the Electrical Engineering department at UCSD. He served as professorfor Information and Computer Science until 1972. While at MIT, he coauthored Principles ofCommunication Engineering, the first text book on digital communications. Dr. Jacobs earnedhis bachelor’s of science degree in electrical engineering from Cornell University, and hismaster’s and doctorate of science degrees in electrical engineering from MIT.

The Institute, similar to comparable institutions, experiences a modest, but certain, annualturnover of faculty. The Institute’s ability to meet its long-term objectives depends significantlyupon the identification, recruitment, and retention of faculty of the highest caliber. The Instituteintends to continue its aggressive efforts to recruit additional faculty to replace those who depart.

SCIENTIFIC PROGRAMS

The Institute’s scientists maintain working relationships with clinical centers throughout theworld to facilitate practical applications of the Institute’s basic science discoveries. Thesediscoveries have the overall objective of discerning the molecular biology and genetic basis ofhuman development and disease so that targeted treatments or cures may be formulated for awide variety of health problems. Groundbreaking discoveries by Salk scientists have helped shedlight on the molecular underpinnings of many devastating conditions including cancer, diabetes,Alzheimer’s disease, obesity, and anomalies of the brain. Several of the Institute’s scientificinitiatives are summarized below:

Aging. Aging is a biological phenomenon that affects virtually every living organism. Butdiseases associated with age will compromise the quality of life and economic well-being ofmany. As we age, the risk of developing Type II diabetes increases; we lose bone and musclemass, leading to frailty; and three-quarters of all cancers are diagnosed after age 55. Anestimated 4.5 million Americans have Alzheimer’s disease, and approximately 60,000 new casesof Parkinson’s disease are diagnosed each year, usually after age 65. As the average age of theU.S. population climbs, the number of people ravaged by diseases related to aging will continueto rise. Salk researchers seek to understand the basic molecular mechanisms that drive the agingprocess and to contribute scientific discoveries that can promote healthy aging. The Institute’sCenter of Aging Research and Mechanistic Analysis (CARMA) focuses on understanding thecascade of events that accompany the aging process.

Biophotonics. Science thrives on new technologies and nothing embodies this better than lightmicroscopy. The convergence of technological advances in several areas – faster cameras, newlight-emitting dyes, and enough computing power to handle images that occupy up to a terabyteof storage space – puts the formerly unthinkable within the grasp of scientific inquiry. Being ableto detect single photons allows scientists to follow molecules throughout the cell, understandhow single molecules and cells function in real time, and decipher what goes wrong when they

A-11

malfunction. One of the foremost goals of Salk researchers is to understand the basic molecularand biochemical principles that guide the function and behavior of living organisms and theindividual cells within. This knowledge will allow Institute scientists to contribute answers toquestions such as: How does Alzheimer’s disease work? How does a cancer cell become a tumorcell? Why are some cancer cells resistant to therapy while others respond? A $20 million giftfrom Institute Trustee Ted Waitt and the Waitt Family Foundation established the WaittAdvanced Biophotonics Center at the Salk Institute, a state-of the art imaging center withinnovative technology in optics, engineering, computer programming, and image processing totake full advantage of recent and future technological advances in the field of biophotonics.

Immunobiology and Microbial Pathogenesis. An increasing number of reports show thatchronic inflammation is the culprit behind the most common illnesses of middle and old age. It iscapable of bursting plaques in coronary arteries leading to heart attacks and damaging nerve cellsin Alzheimer patients. It drives autoimmune disorders and is intricately linked with the early-stage development of cancer and diabetes. The view of inflammation as the driving force behinda wide-ranging variety of diseases has turned immunological research into one of the hottest andmost promising areas of medical research. A gift of $11.5 million, received on behalf of theNomis Foundation, a European foundation established by former Trustee G.H. Thyssen-Bornemisza, helped establish the Nomis Laboratory of Immunobiology and MicrobialPathogenesis at the Salk Institute. The lab’s goal is to shed light on the molecular mechanismsthat cause infectious diseases, define key molecules involved in the body’s response to injury orinfection, and understand why inflammatory processes spin out of control under somecircumstances. The benefits of bringing together a critical mass of internationally outstandingresearchers in inflammation research, synergizing with experts in both microbial pathogenesisand cellular immunology, are potentially enormous. It will enable Salk researchers to make amajor contribution to preventing and treating the cause of a majority of deaths in the UnitedStates and worldwide.

Metabolism. The prevalence of adult obesity has increased an alarming 75% since 1980,rendering one-third of all men and women obese in the U.S. Increased body weight is associatedwith a slew of metabolic disorders including glucose intolerance, insulin resistance, highcholesterol, and high blood pressure, all of which are well-established risk factors forcardiovascular disease and Type II diabetes. Obesity increases the risk for certain cancers andlowers life expectancy. Consistent with its central place in biology, the study of metabolismextends to a number of fields such as aging, cancer, neuroscience, and immunology. A goal atthe Institute is to develop new approaches to understanding how metabolism is affected by foodintake, age, and gender, as well as to identify new targets for pharmacological interventions withthe potential to control weight gain, and to diminish diabetic and cardiovascular complications ofmetabolic syndrome. Recent discoveries by Salk researchers working in such disparate fields asaging, biological chemistry, cancer, and steroid hormone receptors have led them to the great“metabolic intersection”, putting the Salk Institute in a unique position to unravel the body’snetwork of metabolic regulators.

Neuroscience. Our brains perform millions of complex computations every second allowing usto understand language, recognize faces, and schedule our day. We need to know how the brain’sneural circuits form, connect, and function to allow us in turn to understand the brain’s ability to

A-12

adapt and rewire, as well as its remarkable capacity to learn and remember. The key to decodingthe brain – in both healthy and diseased states – lies in exploiting technical and intellectualadvances at every level – from single molecules to large-scale recording technologies – andlinking them with sophisticated behavioral testing. A goal of Salk researchers is to discover howthe 100 billion neurons that make up the brain are produced, grow, and organize into an intricate,functionally active network that controls how we perceive, behave, and remember. Ultimately,Salk researchers want to understand the brain’s development, structure, and mature function insufficient detail to be able to intervene therapeutically in devastating neurological diseases suchas Alzheimer’s and Parkinson’s diseases, and for treating strokes, addiction, schizophrenia, etc.

Plant Biology. All of our lives depend on plants’ ability to harvest the sun’s energy, but theimportance of plant biology is often overshadowed by medical research. Yet, securing theworld’s food supply in a changing climate may be one of the biggest challenges we face thiscentury. Every day 18,000 children under age five die of hunger and malnutrition; almost all ofthem live in developing countries, the very countries expected to be most affected by climatechange. Worldwide fertilizer shortages, rising energy costs, growth of protein-rich diets indeveloping countries, an increasing demand for biofuels, and market speculation all add to thecurrent global food crisis. Understanding the molecular underpinnings of how plants adapt tochallenging environments and defend themselves against insects and fungal infections will becrucial to ensuring the world’s food supply into the future, making basic plant research moreimportant than ever. The Salk Institute is home to some of the world’s leading plant biologistswhose ground-breaking research profoundly impacts many areas of science, from agriculture tostem cell research, from tumor biology to drug development.

Stem Cell Research. Every single cell in our body, from beating muscle cells in our heart toinformation-processing neurons in our brains, from supple skin fibroblasts to bone-producingosteoblasts, can trace its origin to a handful of embryonic stem cells. This is why the amazingversatility of embryonic stem cells holds the tantalizing promise of supplying the body with stemcell transplants to regenerate diseased tissue. But, before Salk scientists can harness the power ofstem cells, they need to learn more about the molecular mechanisms that give cells theirplasticity. A goal at the Salk Institute is to understand how stem cells give rise to all the differentcell types in the body; how they reprogram themselves to become a different cell type; and howthey come together to form tissues and organs. Importantly, Salk researchers will use theseremarkable cells to model human diseases and determine the underlying molecular mechanisms,and then use this knowledge to develop new therapies for those diseases.

Systems Biology. The complexity of even a single cell can be overwhelming. To break down theHerculean task, traditional biologists reduced biological systems into individual components andstudied them gene by gene, protein by protein. But analyzing single cells or aspects of anorganism, such as the cells of the immune system or sugar metabolism, will not reveal how thehuman body functions as a whole. For the first time, scientists can now attempt to vieworganisms as integrated and interacting networks of genes, proteins, and biochemical reactionsthat give rise to life. This unprecedented ability is possible with the help of the genetic “partscatalog” provided by the Human Genome Project, the development of powerful new researchtechnology, more efficient computing power, and the ease of storing and distributing massiveamounts of data over the Internet. Scientists can only hope to understand the fundamental

A-13

working principles of life by studying the interactions of all the parts that comprise a wholeorganism. The growing understanding of how genes and proteins work enables scientists at theInstitute to take an increasingly global approach to addressing biological questions. This willlead to rapid advances in understanding disease-causing alterations in the molecular networksunderlying metabolic, physiological, and behavioral processes.

PLANT AND EQUIPMENT

FacilitiesThe Institute’s campus consists of a 26-acre site and four buildings, two of which each consist of212,000 gross square feet of space, and two which consist of 113,000 gross square feet at 10010North Torrey Pines Road in La Jolla, California. The original site of the Institute’s facilities wasdeeded to the Institute by the citizens of San Diego and is adjacent to the campus of theUniversity of California, San Diego. This location provides ready access to the University aswell as to other members of San Diego's research community including The Scripps ResearchInstitute and Sanford/Burnham Medical Research Institute, and is home to one of the largestconcentrations of biotechnology companies in the United States. The buildings were designedspecifically for the scientific work of the Institute by architect Louis Kahn in conjunction withJonas Salk.

Technical Support ActivitiesThe research activities of Institute scientists require significant technical support including corefacilities such as the Razavi Newman Center for Bioinformatics, the Center of Cytometry andMolecular Imaging, the Functional Genomics Core, the Peptide Synthesis Facility, The VincentJ. Coates Foundation Mass Spectometry Center, the Stem Cell Core Facility, the TransgenicCore, and many other specialized facilities devoted to collaborative research.

FINANCIAL OPERATIONS

GrantsGrants provide the major source of revenue for the Institute's research activities. In the fiscalyear ended June 30, 2009, the Institute received approximately $71 million of government andother private and public grants and contracts, including $55 million from the federal government,primarily from the NIH. Other grantors include California Institute for Regenerative Medicine,Sanofi-Aventis, National Science Foundation, University of California, Clayton Foundation,Leona M. & Harry B.

The Salk InstituteSources of Grants Revenue

Grant funding for the first nine months of fiscal year 2010, is 10% or $5 million higher than thesame period in fiscal year 2009, with grants from corporations and other and from the State ofCalifornia increasing $3 million and $1 million, respectively. Through March 31, 2010, grantsfrom the NIH and from all other sources increased slightly.

NIH Funding ProcessThe NIH utilizes a competitive process to award the funds available to its research programs.The Institute's scientists submit grant applications that are reviewed and rated through the NIHpeer review process. NIH officials make the final award decision based on the percentile rankingassigned to the application relative to all other applications. While the awards are generally for aperiod of four to five years and provide for a budget to cover direct and indirect costs, some ofthe Institute's senior scientists are recipients of NIH Merit Awards that provide funding for aperiod of seven to ten years.

Direct and Indirect CostsThe Institute's research programs are supported by two types of costs:

1. Direct Costs are directly charged to a research project and include wages of scientistsand technicians, supplies and grant-specific equipment; and

2. Indirect Costs are also incurred in the performing of research, but they have beenincurred for purposes common to some or all of the research programs and includeinterest on long-term debt, depreciation, utilities, occupancy and facility costs, andgeneral management and administrative services such as accounting, purchasing, humanresources and the library.

The federal Office of Management and Budget ("OMB") has established indirect cost

A-15

reimbursement recovery principles and procedures to ensure that the federal government bears afair share of the total costs associated with research programs. While the cost principles areintended to provide for sharing and allocation of indirect costs, certain costs are not allowable.For example, fundraising and other specified miscellaneous costs are not reimbursable.

Each year, the Institute negotiates, prospectively, an indirect cost rate with the U.S. Departmentof Health and Human Services. The indirect costs that are recovered with respect to anyindividual grant are determined by applying the negotiated indirect cost rate to the total of thatgrant's direct costs which are subject to indirect cost reimbursement.

Although institutional authorizations for grants from federal agencies have been funded in pastyears, they are subject to annual congressional appropriations and payment. No assurance can begiven that such appropriations or payments will be made in the future or that the various forms offederal grant programs will continue at current levels. A loss or significant reduction of suchprograms could have a material adverse effect on the Institute's activities and financial position.The Institute's management is not currently aware that any such programs will be discontinued ormaterially reduced.

Other Research SupportAnother source of research funding at the Institute is the Howard Hughes Medical Institute("HHMl"). HHMI is an operating foundation that conducts research at the Institute's facilities byvirtue of the First Amended and Restated Collaboration Agreement with the Institute datedJanuary 15, 1991, as amended by the First Amendment dated September 1, 1993 (the"Collaboration Agreement"). The Collaboration Agreement provides that the Institute and HHMIwill conduct a research program in the fields of neuroscience and plant biology funded byHHMl, in space at the Institute's facility, by specified scientists. Since the costs of such researchprogram are borne directly by HHMI, the direct costs of this research are not included in thefinancial statements of the Institute. Under the Collaboration Agreement, HHMI pays theInstitute a fee for occupancy, utilities, and services. In the fiscal year ended June 30, 2009, thosedirect costs were approximately $7 million. As of June 30, 2009, HHMI had seven investigatorswho are members of the Faculty of the Institute and they operate in approximately 24,400 netusable square feet of laboratory space.

Fund Raising ProgramsThe Institute has enjoyed considerable success in fundraising in past years and anticipatesfundraising will continue to provide a significant source of revenue. The Institute has or isreceiving funding from the major foundations involved in biomedical research, including:Howard Hughes Medical Institute; Bill and Melinda Gates Foundation; Joan and Irwin JacobsFund of the Jewish Community Foundation; Waitt Family Foundation; Leona M. and Harry B.Helmsley Charitable Trust; Glenn Foundation for Medical Research; G. Harold & Leila MathersCharitable Foundation; the H.A. and Mary K. Chapman Charitable Trust; the Clayton MedicalResearch Foundation, Inc.; the Nomis Foundation; the Larry L. Hillblom Foundation; SkirballFoundation; Henry L. Guenther Foundation; Hearst Foundation; the H.N. and Frances C. BergerFoundation; W. M Keck Foundation; Pew Charitable Trusts; the James S. McDonnellFoundation; the Alfred P. Sloan Foundation; the Kohlberg Foundation, Inc., The Samuel Roberts

A-16

Nobel Foundation, Inc., the Christopher Reeve Foundation; and the Hilton Foundation. Inaddition, the March of Dimes Birth Defects Foundation provides in excess of $1 millionannually. Attracting and retaining these sources of support, with the assistance of the Board, isthe responsibility of the President, Development Office, the Faculty, and other members of theexecutive management.

Technology Transfer ActivitiesThe Institute and its scientists are responsible for many commercially relevant discoveries. Thepassage of the Bayh-Dole Act in 1980 permits the Institute and all NIH grantees to retain title toand manage the commercialization of intellectual property generated with NIH funding. Underfederal law, the U.S. Government has a right to take over the licensing effort with respect to agiven invention under certain circumstances. To date, the U.S. Government has not exercisedthis right. While the Institute has been successful in its licensing efforts to date, there is nocertainty that such efforts will be successful in the future.

Since the early 1980s, the Institute has entered into research funding agreements with for-profitpharmaceutical and biotechnology firms that have provided funding in exchange for options tolicense Institute technology. Most recently, the Institute has entered into strategic alliances withtwo worldwide pharmaceutical companies to work on collaborations to translate Institute basicscience into potential human therapeutics and diagnostics. The Institute has also entered intotechnology license agreements with for-profit entities. These license agreements have provided avehicle to transfer the Institute's basic research findings into commercial products. There areapproximately 250 active license agreements. The Institute has held over 1,000 United Statesand foreign patents, of which 480 are active and approximately 250 are pending United Statesand foreign patent applications. Over the years, thirty-one companies have been formed based onInstitute discoveries. Revenues from license agreements accounted for approximately 3% oftotal revenues in the last five fiscal years.

The Salk InstituteDetail of Revenues, Gains, and Other Support

For the first nine months of fiscal year 2010, grant revenues and contributions represent 68% and23%, respectively, of total revenues, gains, and other support. Investment return designated forcurrent operations represents 5% of total revenues, and other income comprise the remaining4%.

MANAGEMENT'S DISCUSSION AND ANALYSIS

The Institute is a nonprofit public benefit corporation. Operations are managed to producesufficient resources to allow the Institute to meet its operating goals and its commitment to thescientific community, to generate funds for the future development of new programs, and toprovide operating flexibility. The following highlights some of the key trends in the itemscomprising revenue, support and expenditures.

Grants and ContractsSince fiscal year 2005, grants and contracts for research have remained steady in the range of$70.5 million to $73.8 million as congressional appropriations to the NIH have leveled out since2004. Management attributes the Institute’s ability to maintain its grant funding level to itssuccess in attracting and retaining researchers who are successful in obtaining funding from theNIH and other sources. The Institute has an average award rate for grant applications of 30.4%.According to NIH reports, the average national success rate for the NIH is only 20.6%.

Grants – Indirect Cost ReimbursementVariations in the Institute's total indirect cost reimbursements from year to year are a function ofthe total amount of actual indirect costs, the level of direct research, the NIH-approved indirectcost rate, and the mix of funding sources. Since 2005, the Institute's NIH-approved indirect costrate has remained relatively constant within a range of 87% to 89.5%. The current provisionalrate for fiscal year 2010 is 90.5%.

A-19

Research ExpendituresResearch expenditures closely coincide with direct and indirect research revenues and support.Budgeting and cost controls of grant expenditures and departmental administrative expenseshave enabled the Institute to maintain a balanced budget or minimize operating deficits in eachof the last five years. In the event external support diminishes, the Institute has the ability toreduce the number of its personnel through attrition and thereby contain operating costs.

Investment Return Designated for Current OperationsThe Board has designated a portion of the Institute's cumulative investment return to be used forsupport of current operations. Under the Institute's spending policy, 5% of the average of themarket value of the Institute's investment balances for the previous three years is appropriated tosupport current operations. In general, these funds provide discretionary resources for the supportof programs and projects not reimbursed by a grantor. Unrestricted investment income providesdiscretionary resources for the support of fundraising, recruiting commitments and otheractivities for which grant support is not available.

Investment Return (Shortfall) in Excess of Amount Designated for Current OperationsThe investment return (shortfall) in excess of the amount designated for current operationsfluctuated significantly over the last five fiscal years and suggests the importance and volatilityof investment income. The Institute's ability to continue to generate investment income isdependent, in part, on market conditions and the allocation of the investment portfolio. The valueof the Institute's investments has fluctuated from time to time and is expected to fluctuate in thefuture. Variations in market performance may impact the Institute's level of earnings from itsinvestments. See "Investments-Investment Policy" below.

Diversification is achieved through investments indomestic and international common stocks, bonds, mutual funds, cash equivalents, limitedpartnerships in marketable alternative strategies and other investments. Additional diversificationis achieved by allocating assets to various investment styles within asset classes and retaininginvestment managers with complementary investment philosophies, styles and approaches. Theallocation to alternative investments includes long/short equity, distressed/special situations andabsolute return strategies. Management is not aware of any non-compliance with the policies.

The Institute’s investment allocation targets as of March 31, 2010, are 70% equities (domesticequity – 25%, global/international equity – 20%, long/short equity – 20%, and private equity –5%), 15% fixed income, 15% special situations, and 5% cash.

INDEPENDENT AUDITOR’S REPORT Board of Trustees The Salk Institute for Biological Studies We have audited the accompanying statements of financial position of The Salk Institute for Biological Studies (Institute) as of June 30, 2009 and 2008 and the related statements of activities and cash flows for the years then ended. These financial statements are the responsibility of the Institute’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Institute’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of The Salk Institute for Biological Studies as of June 30, 2009 and 2008, and the changes in its net assets and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands)

Note 1 – Nature of the Institute

The Salk Institute for Biological Studies, San Diego, California (the “Institute”), conducts basic biomedical research funded primarily with grants and contributions from agencies of the United States government, foundations, and the general public. The Institute is a California not-for-profit public benefit corporation exempt from federal income taxes under section 501(c)(3) of the Internal Revenue Code and section 23701(d) of the California Revenue and Taxation Code. Income determined to be unrelated business income is taxable, when present.

Note 2 – Significant Accounting Policies

General: The financial statements have been prepared on the accrual basis of accounting and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Net assets and activities are presented as unrestricted, temporarily restricted, and permanently restricted based on related donor restrictions or lack of such restrictions. Unrestricted net assets represent expendable funds available for operations, which are not otherwise limited by donor restrictions. Temporarily restricted net assets consist of contributed funds whose use is limited by donor-imposed restrictions that either expire by passage of time or can be fulfilled and removed by actions of the Institute pursuant to the stipulations. Permanently restricted net assets are subject to irrevocable donor restrictions requiring the assets be maintained in perpetuity, usually for the purpose of generating investment income to fund current operations. The costs of providing the program and other activities are summarized on a functional expense basis in the statement of activities. Accordingly, certain costs have been allocated among the programs and supporting services benefited. Revenue Recognition

Grants: Grant revenue is recognized as unrestricted revenue when the related research costs are incurred, up to the maximum grant amount. Unspent grant funds received in advance of the related expenditures are reported as unexpended advances. Reimbursement for indirect expenses on certain research grants is based on a fixed rate applied to allowable direct expenses. Contributions: Contributions are recorded as revenue at their fair value when unconditionally pledged or when received, whichever is earlier. Contributions subject to donor-imposed restrictions for use in a future period or for a specific purpose are reported as either temporarily or permanently restricted depending on the nature of the donor’s restriction. When a donor restriction expires or is fulfilled, temporarily restricted net assets are reclassified to unrestricted net assets and reported in the statement of activities as net assets released from restrictions. Contributions of equipment or other long-lived assets are recognized when pledged or received, whichever is earlier, and recorded at the fair value of the contributed asset at the time of donation. If donors stipulate how long the assets must be used, the contributions are recorded as restricted support. In the absence of such stipulations, contributions of property and equipment are recorded as unrestricted support.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands)

Note 2 – Significant Accounting Policies (Continued) Cash and Cash Equivalents: Cash and cash equivalents are defined as cash on hand and in banks, plus highly liquid investments, which fund the daily operating activities of the Institute and have a maturity, at the date of purchase, of three months or less. Cash and cash equivalents held within the investment portfolio as part of the Institute’s investment strategy are included in investments on the statement of financial position. Receivables and Other Assets: Receivables and other assets include amounts billed and unbilled on grants and other agreements through June 30. An allowance for estimated uncollectible accounts is recorded based on past experience and on an analysis of current receivable balances. Accounts are written off against the allowance when deemed uncollectible. Management has determined that an allowance of $70 and $80 is necessary at June 30, 2009 and 2008, respectively. Also included in receivables and other assets is the Institute’s beneficial interest in split-interest agreements which provide for the payment of distributions to the donor or other designated beneficiaries over the split-interest agreement’s term (usually the beneficiary’s lifetime). At the end of a split-interest agreement’s term, the remaining assets are available for use by the Institute for the purpose specified by the donor. The portion of the assets attributable to the fair value of the future benefits to be received by the Institute is recorded in the statement of activities as temporarily or permanently restricted contribution revenue in the year the split-interest agreement is established. The fair value of the Institute’s beneficial interest in split-interest agreements is calculated based on a discounted cash flow model using applicable mortality tables and discount rates of 2.8 percent and 3.8 percent at June 30, 2009 and 2008, respectively. The fair value of the Institute’s beneficial interest in split-interest agreements totaled $2,123 and $2,754 at June 30, 2009 and 2008, respectively. At June 30, 2009 and 2008, $1,900 and $2,082, respectively, in notes receivable from employees of the Institute for relocation expenses are included in receivables and other assets. The notes bear interest at rates ranging from 0 percent to 6 percent, are secured by second priority deeds of trust, and are forgiven or repaid over terms of 2 to 12 years, subject to continued employment and service to the Institute. Contributions Receivable: Contributions receivable consists of unconditional promises to give. Unconditional promises to give that are expected to be collected in future years are recorded at fair value when the promise is made based on a discounted cash flow model. The discounts on these amounts are computed using risk-free rates established at the time those promises are received. The discount rate for the contributions receivable range from .9 percent to 4.5 percent and from 2.0 percent to 4.5 percent for fiscal years 2009 and 2008, respectively. Amortization of the discounts is included in contributions. Conditional promises to give are not recorded as revenue until the conditions are substantially met. An allowance for estimated uncollectible contributions receivable is recorded based on management’s judgment and analysis of the creditworthiness of the donors, past collection experience, and other relevant factors. Accounts are written off against the allowance when deemed uncollectible. Management has determined that no allowance for uncollectible contributions receivable is necessary as of June 30, 2009 and 2008.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands)

Note 2 – Significant Accounting Policies (Continued) Investments: Investments in marketable equity securities and all investments in debt securities are carried at their fair values based on quoted market prices. Non-marketable securities for which quoted market prices are not available are valued at fair value by third-party fund managers or the general partners of the related investment partnerships, based on factors deemed relevant by the general partners including, but not limited to, market conditions, purchase price, estimated liquidation value, restrictions on transfer, and meaningful third-party transactions in the private market. The Institute reviews and evaluates the values provided by third-party fund managers and general partners and agrees with the valuation methods and assumptions used in determining the fair value of non-marketable securities, including alternative investments. For these investments, the Institute uses the net asset value (“NAV”) provided by the investment fund managers to evaluate the fair value of the investments. The NAV may be adjusted based on liquidity factors or other information about the investments that management considers significant to the valuation of the investments. Realized and unrealized gains and losses are included in the change in net assets in the accompanying statement of activities. The Institute’s portfolio is managed by independent professional investment managers subject to direction and oversight by a committee of the Board of Trustees. Certain of these managers are authorized to invest a limited portion of the Institute’s portfolio in alternative investments to increase portfolio diversification and return and reduce volatility. Funds Held by Trustee: Funds held by trustee are amounts required to be held in a separate account under the Certificates of Participation agreements (Note 6) and are comprised of cash and cash equivalents. Property: Property is carried at cost. Donated property is recorded at its fair value as determined at the time of contribution. The Institute capitalizes acquisitions of property of $5 or more. Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the assets ranging from 3 to 50 years. Impairment of Long-lived Assets: The Institute evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If the estimated future cash flows (undiscounted and without interest charges) from the use of an asset are less than the carrying value, a write-down will be recorded to reduce the related asset to its estimated fair value. To date, no such write-downs have occurred. Endowments: The Institute’s endowment consists of approximately 60 individual funds established for a variety of purposes. The endowment includes both donor-restricted endowment funds and funds designated by the Board of Trustees to function as endowments. Net assets associated with endowment funds, including funds designated by the Board of Trustees to function as endowments, are classified and reported based on the existence or absence of donor-imposed restrictions.

Note 2 – Significant Accounting Policies (Continued) In August 2008, the Financial Accounting Standards Board (“FASB”) issued Staff Position FAS 117-1, Endowments of Not-for-Profit Organizations: Net Asset Classification of Funds Subject to an Enacted Version of the Uniform Prudent Management of Institutional Funds Act and Enhanced Disclosures for All Endowment Funds (“FSP FAS 117-1”). FSP FAS 117-1 provides guidance on the net asset classification of donor-restricted endowment funds for a not-for-profit organization that is subject to an enacted version of the Uniform Prudent Management of Institutional Funds Act of 2006 (“UPMIFA”). Effective January 1, 2009, the State of California enacted a version of UPMIFA, the provisions of which apply to endowment funds existing on or established after that date. The Institute has considered the effects of and implemented UPMIFA during the year ended June 30, 2009. A key component of FSP FAS 117-1 is an interpretation by the FASB that there is a requirement to classify the portion of a donor-restricted endowment fund that is not classified as permanently restricted net assets as temporarily restricted net assets until those funds have been appropriated for expenditure. The Institute has reviewed its net assets to identify the cumulative amount of unspent endowment earnings that had not yet been appropriated for expenditure as of January 1, 2009, and determined that no reclassification of net assets from unrestricted to temporarily restricted was necessary. The Board of Trustees of the Institute has interpreted California’s enacted version of UPMIFA as requiring the preservation of the fair value of the original gift as of the gift date of the donor-restricted endowment funds, absent explicit donor stipulations to the contrary. As a result of this interpretation, the Institute classifies as permanently restricted net assets (a) the original value of gifts donated to the permanent endowment, (b) the original value of subsequent gifts to the permanent endowment, and (c) accumulations to the permanent endowment made in accordance with the direction of the applicable donor gift instrument at the time the accumulation is added to the fund. The remaining portion of the donor-restricted endowment fund that is not classified in permanently restricted net assets is classified as temporarily restricted net assets until those amounts are appropriated for expenditure by the Institute in a manner consistent with the standard of prudence prescribed by UPMIFA. In accordance with UPMIFA, the Institute considers the following factors in making a determination to appropriate or accumulate donor-restricted endowment funds:

1) The duration and preservation of the fund; 2) The purposes of the Institute and the donor-restricted endowment fund; 3) General economic conditions; 4) The possible effect of inflation and deflation; 5) The expected total return from income and the appreciation of investments; 6) Other resources of the Institute; and 7) The investment policies of the Institute.

The Institute has adopted investment and spending policies for endowment assets that attempt to provide a predictable stream of funding to programs and activities supported by its endowment while seeking to maintain the purchasing power of the endowment assets. The Institute’s spending and investment policies work together to achieve this objective. The investment policy establishes an achievable return objective through diversification of asset classes. The current long-term return objective is a total return, over rolling ten-year periods, which exceeds inflation by an average of 5.5 percent per year. Actual returns in any given year may vary from this amount.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands)

Note 2 – Significant Accounting Policies (Continued) To satisfy its long-term rate-of-return objectives, the Institute relies on a total return strategy in which investment returns are achieved through both capital appreciation (realized and unrealized) and current yield (interest and dividends). The Institute targets a diversified asset allocation that places a greater emphasis on equity-based investments to achieve its long-term return objectives within prudent risk constraints. The Institute has a policy of appropriating for distribution each year a percentage of its endowment funds’ average fair value over the prior 12 quarters through the calendar year-end preceding the fiscal year in which the distribution is planned. The percentage distribution is determined annually by the Board in the budget approval process and was 5 percent for each of the years ended June 30, 2009 and 2008. In establishing this policy, the Institute considered the long-term expected return on its endowment. Accordingly, over the long term, the Institute expects the current spending policy to allow its endowment to grow at an average of .5 percent over inflation annually. This is consistent with the Institute’s objective to maintain the purchasing power of the endowment assets held in perpetuity or for a specified term as well as to provide additional real growth through new gifts and investment return. Use of Estimates: The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair Value of Financial Instruments: The Institute carries certain assets at fair value as described in Note 9. The Institute has determined the fair value of these assets in accordance with the provisions of Statement of Financial Accounting Standards No. 157, Fair Value Measurements, (“SFAS No. 157”) which provides a framework for measuring fair value under GAAP. SFAS No. 157 has been applied prospectively as of the beginning of fiscal year 2009. The carrying values of cash and cash equivalents, receivables, and accounts payable approximate their fair values due to the relatively short period of time between origination of the instruments and their expected realization. Risks and Uncertainties: The Institute invests in various types of securities which are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near-term and such changes could materially affect the amounts reported in the statement of financial position. In 2009 and 2008, there has been significant volatility in the domestic and international investment markets, primarily as a result of liquidity issues in credit markets. Consequently, the fair value of the Institute’s investments is exposed to higher than typical price volatility which could result in a substantial reduction in the fair value of certain investments from the amounts reported as of June 30, 2009.

Note 2 – Significant Accounting Policies (Continued)

Subsequent Events: Subsequent events are events or transactions that occur after the statement of financial position date but before financial statements are issued. The Institute recognizes in the financial statements the effects of all significant subsequent events that provide additional evidence about conditions that existed at the date of the statement of financial position, including the estimates inherent in the process of preparing the financial statements. The Institute’s financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the statement of financial position but arose after the statement of financial position date and before financial statements are available to be issued. The Institute has evaluated subsequent events through October 29, 2009, which is the date the financial statements are issued.

Note 3 – Contributions Receivable Contributions receivable are summarized as follows at June 30:

Total contributions receivable, net 12,535$ 17,599$

At June 30, 2009 and 2008, net pledges receivable of $3,558 and $1,340, respectively, are from members of the Board of Trustees of the Institute. In 2008, the Institute received two conditional promises to give from members of the Board of Trustees. One of the conditional gifts is a promise to give $1,000 for each $2,000 endowed chair established by other donors, up to a maximum of $10,000. A pledge for $2,000 was received in 2009, and the related matching pledge of $1,000 was recorded. The second conditional gift is a promise to match up to $20,000 in contributions for any purpose resulting from a specific development plan over five years ending April 30, 2013. The promised matching funds are restricted for the creation of a biophotonics center. An advance payment of $3,000 was received from the donor in May 2008 and recorded as a refundable advance. Contributions of $2,146 and $150 were received in response to the development plan in 2009 and 2008, respectively. As a result, $2,296 of the refundable advance has been recognized as temporarily restricted contributions, and the remaining $704 is included in unexpended advances in the statement of financial position as of June 30, 2009. In late 2009, the Institute received a conditional promise to give from a member of the Board of Trustees to match up to $1,000 raised to fund a specific capital project.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 6 – Debt (Continued)

In July 2005, the Institute issued revenue bonds through the California Statewide Communities Development Authority totaling $25,135 to prepay, together with other available moneys, $26,940 aggregate principal amount of the outstanding Certificates of Participation issued in 1994 to fund the construction of the research buildings expansion project. The 2005 bonds consist of $25,135 in serial bonds due from July 1, 2007 through July 1, 2024 at interest rates ranging from 3.00 percent to 5.25 percent. At June 30, 2009, a premium of $471 on the bonds is being amortized over the life of the bonds.

As of June 30, 2009, future annual principal payments under the Certificates of Participation and revenue bonds are as follows:

Years ending June 30,2010 1,325$ 2011 1,370 2012 1,425 2013 1,480 2014 1,530 Thereafter 28,150

35,280$

The Institute’s debt is collateralized by all of the revenue of the Institute and further secured by a deed of trust on the Institute’s main campus. The fair value of the debt as of June 30, 2009 and 2008 is approximately $34,715 and $36,959, respectively, based on current interest rates for obligations with similar terms. Issuance costs related to the Certificates of Participation and revenue bonds are included in receivables and other assets in the accompanying statements of financial position and are being amortized over the life of the certificates; the unamortized balance of such costs is $873 and $935 at June 30, 2009 and 2008, respectively. Amortization expense related to the issuance costs was $62 for each of the years ended June 30, 2009 and 2008. Interest expense related to the Certificates of Participation and revenue bonds was $1,683 and $1,727 for the years ended June 30, 2009 and 2008, respectively. Under the terms of the Certificates of Participation and revenue bonds, the Institute is subject to compliance with certain covenants, including restrictions on additional indebtedness.

From time to time, the fair value of assets associated with individual donor-restricted endowment funds may fall below the level that the donor or UPMIFA requires the Institute to retain as a fund of perpetual duration. In accordance with GAAP, deficiencies of this nature are reported in unrestricted. As of June 30, 2009 and 2008, respectively, these deficiencies totaled $3,673 and $80. These deficiencies resulted from unfavorable financial market conditions over the past year.

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 8 – Employee Benefit Plans

Retirement Plans: The Institute has an Employee Retirement Plan and a Professor and Executive Officer Retirement Plan for certain of its employees. Both plans are defined contribution plans under which the Institute contributes a percentage of the participant’s annual compensation. The Institute’s contributions are made in accordance with section 403(b) of the Internal Revenue Code. Total contributions expense related to both plans was $4,096 and $4,070 for the years ended June 30, 2009 and 2008, respectively. Retiree Health Benefits Plan: The Institute sponsors a defined benefit plan (the “Plan”) that provides for retirees’ health and related benefits. Employees hired prior to June 30, 1993 may become eligible for these postretirement benefits upon attainment of age 60 with 10 years of service. The Plan contains cost-sharing features such as deductibles, coinsurance, and contributions, which can be adjusted annually, and the Institute’s policy is to fund these benefits through a rabbi trust. The Institute uses a June 30 measurement date for the Plan. The changes in the accumulated postretirement benefit obligation for the Plan are as follows:

2009 2008

Benefit obligation, beginning of year 5,629$ 5,491$ Service cost 34 34 Interest cost 334 330 Actuarial gain (170) (52) Benefits paid (167) (174)

Benefit obligation, end of year 5,660$ 5,629$

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 8 – Employee Benefit Plans (Continued)

The deferred transition obligation and deferred actuarial gains and losses are not reflected in net periodic postretirement benefit cost and are included in unrestricted net assets at June 30. The changes in the deferred amounts are as follows:

Deferred Transition Deferred TransitionGain Obligation Gain Obligation

Balance, beginning of year 1,370$ (816)$ 1,408$ (933)$ Actuarial gain 170 - 52 - Amortization

Balance, end of year 1,439$ (699)$ 1,370$ (816)$

2009 2008

The amounts of the transition obligation and the net actuarial gain included in unrestricted net assets at June 30, 2009 that are expected to be recognized in net periodic postretirement benefit cost during the fiscal year ending June 30, 2010 are ($117) and $103, respectively. The benefits expected to be paid from the Plan in each of the next five years and in the aggregate for the following five years are as follows:

Years ending June 30,2010 391$ 2011 411 2012 410 2013 404 2014 413 2015-2019 2,092

4,121$

Contributions to the Plan are expected to equal benefit payments. For the years ended June 30, 2009 and 2008, employer contributions were $167 and $174, respectively, and participant contributions were $98 and $100, respectively. The Plan’s weighted-average assumptions used to determine net periodic postretirement benefit cost for the years ended June 30 were as follows:

2009 2008

Discount rate 6.25% 6.25%Rate of compensation increase 5.00% 5.00%

20

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 8 – Employee Benefit Plans (Continued)

The amounts reported are affected by the healthcare trend assumptions. The assumed healthcare cost trend rate used in measuring the accumulated benefit obligation was 10 percent for 2009 and 2008 and is assumed to decrease gradually to 5 percent in 2020 and remain at that level thereafter. If the healthcare cost trend assumptions were increased by 1 percent, the accumulated postretirement benefit obligation at June 30, 2009 and 2008 would be increased by approximately $104 and $100, respectively. The effect of this change would increase the aggregate of the service and interest cost components of the net periodic postretirement benefit cost by approximately $6 in each of the years ended June 30, 2009 and 2008. If the healthcare cost trend assumptions were decreased by 1 percent, the accumulated postretirement benefit obligation as of June 30, 2009 and 2008 would be decreased by approximately $93 and $91, respectively. The effect of this change would reduce the aggregate of the service and interest cost components of the net periodic postretirement benefit cost by approximately $6 and $5 for the years ended June 30, 2009 and 2008, respectively.

Note 9 – Fair Value of Financial Instruments

SFAS No. 157 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. SFAS No. 157 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

� Level 1 – quoted prices in active markets for identical assets or liabilities; � Level 2 – inputs, other than quoted prices, that are observable for the asset or liability, either

directly or indirectly, including inputs in markets that are not considered to be active; and � Level 3 – unobservable inputs that are supported by little or no market activity and that are

significant to the fair value of the assets or liabilities.

The following table presents information about each major category of the Institute’s financial assets measured at fair value on a recurring basis as of June 30, 2009:

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 9 – Fair Value of Financial Instruments (Continued)

The following table presents the summary of changes in the fair value of the Institute’s Level 3 classified assets for 2009:

BeneficialInterest in

Realized and unrealized losses of $7,023 are reported in the statement of activities as a component of investment losses in excess of amount designated for current operations. The change in the value of the beneficial interest in split-interest agreements is included in contributions on the statements of activities. Of the total fiscal year 2009 net losses that are included in investment losses in excess of amount designated for current operations, $6,196 are due to unrealized gains and losses from Level 3 assets still held at June 30, 2009.

See Note 2 for the valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying statements of financial position. The Institute had no liabilities required to be reported at fair value at June 30, 2009.

Note 10 – Commitments and Contingencies Commitments: At June 30, 2009, contractual commitments on construction and purchases pending or in process are $6,503. In addition, the Institute has a capital commitment of $3,120 for a private equity investment at June 30, 2009.

Leases: The Institute has entered into operating leases for building space and equipment that expire through March 2014. Rent expense totaled $683 and $709 for the years ended June 30, 2009 and 2008, respectively. Future minimum rental payments required under non-cancelable operating leases that have remaining lease terms in excess of one year as of June 30, 2009, are as follows:

Years ending June 30,2010 675$ 2011 360 2012 100 2013 49 2014 8 Total 1,192$

22

THE SALK INSTITUTE FOR BIOLOGICAL STUDIES NOTES TO FINANCIAL STATEMENTS (In Thousands) Note 10 – Commitments and Contingencies (Continued)

Workers’ Compensation Claims: The Institute self-insures for workers’ compensation claims to a maximum of $250 per claim for years prior to fiscal year 2007. Under an arrangement with an insurance carrier, amounts in excess of this level are the responsibility of the insurer. The Institute maintains an accrual reflecting its expected claims obligation under this arrangement that is adjusted in future periods as claims are finalized. The Institute obtained a letter of credit as required by the workers’ compensation arrangement in the amount of $70 for each of the years ended June 30, 2009 and 2008, respectively. There were no draws on the letter of credit in 2009 or 2008. Grants: The Institute has grants with various organizations and government agencies which are subject to audit. Management believes that any liability which may result from these audits would not be material. Income Taxes: The Institute adopted the provisions of Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the “Interpretation”), on July 1, 2007. No adjustment to net assets was required upon the adoption of the Interpretation, as the Institute had no unrecognized tax benefits. The Institute has no unrecognized tax benefits as of June 30, 2009 and 2008. The Institute files an exempt organization tax return in the United States federal jurisdiction and a copy with the state charities division. With few exceptions, the Institute is no longer subject to United States federal or state/local income tax examinations by tax authorities for years before 2006. Legal: The Institute is a party to certain legal actions arising in the ordinary course of business. In the opinion of management, additional liabilities, if any, under these actions will not result in material charges against net assets. Guarantees and Indemnities: From time to time, the Institute enters into certain types of contracts that contingently require the Institute to indemnify parties against third-party claims. These contracts primarily relate to: (i) certain technology transfer/license agreements under which the Institute may be required to indemnify licensees, and (ii) certain agreements with the Institute’s officers, directors, and employees, under which the Institute may be required to indemnify such persons for liabilities arising out of their employment relationship. The terms of such obligations vary by contract and, in most instances, a specific or maximum dollar amount is not explicitly stated therein. Generally, amounts under those contracts cannot be reasonably estimated until a specific claim is asserted. Consequently, no liabilities have been recorded for these obligations on the Institute’s statements of financial position for the years ended June 30, 2009 and 2008.

FORMOF FINAL OPINION OF SPECIAL COUNSEL

Upon execution and delivery of the Certificates, Orrick, Herrington & Sutcliffe LLP, Los Angeles,California, Special Counsel, proposes to render its final approving opinion with respect to theCertificates in substantially the following form:

[Date of Delivery]

Board of Supervisors of theCounty of San Diego1600 Pacific HighwaySan Diego, California 92101

Certificates of ParticipationEvidencing Proportionate Interests of the Holders Thereof

in Installment Payments to be Paid by theCounty of San Diego

from Purchase Payments to be Received fromThe Salk Institute for Biological Studies, San Diego, California

(Final Opinion)

Ladies and Gentlemen:

We have acted as special counsel to the County of San Diego, California (the “County”) inconnection with the execution and delivery of $37,445,000 principal amount of certificates ofparticipation (the “Certificates”), each evidencing a proportionate ownership interest of the holdersthereof in the rights to receive certain installment payments (the “Installment Payments”) to be paid bythe County pursuant to an installment purchase agreement, dated as of May 1, 2010 (the “PurchaseAgreement”), between the County and The Salk Institute for Biological Studies, San Diego, California(the “Corporation”), all of which rights to receive such Installment Payments having been assignedwithout recourse by the Corporation to The Bank of New York Mellon Trust Company, N.A., as trustee(the “Trustee”). The Certificates have been executed by the Trustee pursuant to the terms of a trustagreement, dated as of May 1, 2010 (the “Trust Agreement”), among the County, the Corporation and theTrustee. Capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in aninstallment sale agreement, dated as of May 1, 2010 (the “Sale Agreement”), between the County and theCorporation.

In such connection, we have reviewed the Purchase Agreement, the Sale Agreement, the TrustAgreement, a Tax Certificate and Agreement, dated the date hereof (the “Tax Agreement”), between theCounty and the Corporation, opinions of counsel to the County, the Corporation and the Trustee,certificates of the County, the Corporation, the Trustee and others, and such other documents, opinionsand matters to the extent we deemed necessary to render the opinions set forth herein.

We have relied on the opinion of Allen Matkins Leck Gamble Mallory & Natsis LLP, LosAngeles, California, Counsel to the Corporation, regarding, among other matters, the current qualificationof the Corporation as an organization described in Section 501(c)(3) of the Internal Revenue Code of1986 (the “Code”) and use of the facilities financed and refinanced with the proceeds of the Certificates inactivities that are not considered unrelated trade or business activities of the Corporation within the

E-2

meaning of Section 513 of the Code. We note that such opinion is subject to a number of qualificationsand limitations. Furthermore, Counsel to the Corporation cannot give and has not given any opinion orassurance about the future activities of the Corporation, or about the effect of future changes in the Code,the applicable regulations, the interpretation thereof or changes in enforcement thereof by the InternalRevenue Service. Failure of the Corporation to be organized and operated in accordance with the InternalRevenue Service’s requirements for the maintenance of its status as an organization described in Section501(c)(3) of the Code, or to operate the facilities financed and refinanced by the Certificates in a mannerthat is substantially related to the Corporation’s charitable purpose under Section 513(a) of the Code, mayresult in the interest portion of the Installment Payments to be paid by the County under the PurchaseAgreement and received by the Beneficial Owners being included in federal gross income, possibly fromthe date of the original execution and delivery of the Certificates.

The opinions expressed herein are based on an analysis of existing laws, regulations, rulings andcourt decisions and cover certain matters not directly addressed by such authorities. Such opinions maybe affected by actions taken or omitted or events occurring after the date hereof. We have not undertakento determine, or to inform any person, whether any such actions are taken or omitted or events do occur orany other matters come to our attention after the date hereof. Accordingly, this opinion speaks only as ofits date and is not intended to, and may not, be relied upon in connection with any such actions, events ormatters. Our engagement with respect to the Certificates has concluded with their execution and delivery,and we disclaim any obligation to update this letter. We have assumed the genuineness of all documentsand signatures presented to us (whether as originals or as copies) and the due and legal execution anddelivery thereof by, and validity against, any parties other than the County. We have assumed, withoutundertaking to verify, the accuracy of the factual matters represented, warranted or certified in thedocuments, and of the legal conclusions contained in the opinions, referred to in the second and thirdparagraphs hereof. Furthermore, we have assumed compliance with all covenants and agreementscontained in the Purchase Agreement, the Sale Agreement, the Trust Agreement and the Tax Agreement,including (without limitation) covenants and agreements compliance with which is necessary to assurethat future actions, omissions or events will not cause the interest components of the InstallmentPayments to be included in gross income for federal income tax purposes.

We call attention to the fact that the rights and obligations under the Certificates, the PurchaseAgreement, the Sale Agreement, the Trust Agreement and the Tax Agreement and their enforceabilitymay be subject to bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance,moratorium and other laws relating to or affecting creditors’ rights, to the application of equitableprinciples, to the exercise of judicial discretion in appropriate cases and to the limitations on legalremedies against counties in the State of California. We express no opinion with respect to anyindemnification, contribution, penalty, choice of law, choice of forum, choice of venue, waiver orseverability provisions contained in the foregoing documents nor do we express any opinion with respectto the state or quality of title to or interest in any of the real or personal property described in or subject tothe lien of the Purchase Agreement, the Sale Agreement or the Trust Agreement or the accuracy orsufficiency of the description contained therein of, or the remedies available to enforce liens on, any suchproperty. Finally, we undertake no responsibility for the accuracy, completeness or fairness of theOfficial Statement or other offering material relating to the Certificates and express no opinion withrespect thereto.

Based on and subject to the foregoing, and in reliance thereon, as of the date hereof, we are of thefollowing opinions:

1. The Purchase Agreement, the Sale Agreement and the Trust Agreement have been dulyexecuted and delivered, and constitute valid and binding obligations of the County. The obligation of theCounty to make Installment Payments does not constitute a debt of the County or the State of California

E-3

or any political subdivision thereof within the meaning of any constitutional or statutory debt limit orrestriction.

2. The Trust Agreement creates a valid pledge, to secure the payment of the principal andinterest components of the Installment Payments, of the Revenues and any other amounts (includingproceeds of the sale of the Certificates) held by the Trustee in any fund or account established pursuant tothe Trust Agreement (except the Rebate Fund) subject to the provisions of the Trust Agreementpermitting the application thereof for the purposes and on the terms and conditions set forth in the TrustAgreement.

3. Assuming due authorization, execution and delivery of the Trust Agreement and theCertificates by the Trustee, the Certificates are entitled to the benefits of the Trust Agreement.

4. The interest component of the Installment Payments to be paid by the County under thePurchase Agreement and received by the registered owners of the Certificates is excluded from grossincome for federal income tax purposes under Section 103 of the Code and is exempt from State ofCalifornia personal income taxes. Such interest component is not a specific preference item for purposesof the federal individual or corporate alternative minimum taxes. We express no opinion regarding othertax consequences related to the ownership or disposition of, or the accrual or receipt of interest withrespect to, the Certificates, including whether the interest component of the Installment Payments to bepaid by the County under the Purchase Agreement is included in adjusted current earnings whencalculating corporate alternative minimum taxable income.

Faithfully yours,

ORRICK, HERRINGTON & SUTCLIFFE LLP

APPENDIX F

BOOK-ENTRY ONLY SYSTEM

The information in this Appendix F concerning The Depository Trust Company, New York, NewYork, and DTC’s book entry system has been obtained from DTC and neither the County nor theCorporation takes no responsibility for the completeness or accuracy thereof. The County and theCorporation cannot and do not give any assurances that DTC, DTC Participants or Indirect Participantswill distribute to the Beneficial Owners (a) payments of interest, principal or premium, if any, withrespect to the Certificates, (b) certificates representing ownership interest in or other confirmation orownership interest in the Certificates, or (c) prepayment or other notices sent to DTC or Cede & Co., itsnominee, as the registered owner of the Certificates, or that they will do so on a timely basis, or thatDTC, DTC Participants or DTC Indirect Participants will act in the manner described in thisAppendix F. The current “Rules” applicable to DTC are on file with the Securities and ExchangeCommission and the current “Procedures” of DTC to be followed in dealing with DTC Participants areon file with DTC.

The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for theCertificates (the “Securities”). The Securities will be issued as fully-registered securities registered in thename of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by anauthorized representative of DTC. One fully-registered Security certificate will be issued for each issueof the Securities, each in the aggregate principal amount of such issue, and will be deposited with DTC.

DTC, the world’s largest securities depository, is a limited-purpose trust company organizedunder the New York Banking Law, a “banking organization” within the meaning of the New YorkBanking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning ofthe New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisionsof Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and moneymarket instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit withDTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and othersecurities transactions in deposited securities, through electronic computerized book-entry transfers andpledges between Direct Participants’ accounts. This eliminates the need for physical movement ofsecurities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers,banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-ownedsubsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding companyfor DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of whichare registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to theDTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers,banks, trust companies, and clearing corporations that clear through or maintain a custodial relationshipwith a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has Standard &Poor’s highest rating: AAA. The DTC Rules applicable to its Participants are on file with the Securitiesand Exchange Commission. More information about DTC can be found at www.dtcc.com andwww.dtc.org.

Purchases of Securities under the DTC system must be made by or through Direct Participants,which will receive a credit for the Securities on DTC’s records. The ownership interest of each actualpurchaser of each Security (“Beneficial Owner”) is in turn to be recorded on the Direct and IndirectParticipants’ records. Beneficial Owners will not receive written confirmation from DTC of theirpurchase. Beneficial Owners are, however, expected to receive written confirmations providing details ofthe transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant

F-2

through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in theSecurities are to be accomplished by entries made on the books of Direct and Indirect Participants actingon behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing theirownership interests in Securities, except in the event that use of the book-entry system for the Securities isdiscontinued.

To facilitate subsequent transfers, all Securities deposited by Direct Participants with DTC areregistered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may berequested by an authorized representative of DTC. The deposit of Securities with DTC and theirregistration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficialownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s recordsreflect only the identity of the Direct Participants to whose accounts such Securities are credited, whichmay or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsiblefor keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by DirectParticipants to Indirect Participants, and by Direct Participants and Indirect Participants to BeneficialOwners will be governed by arrangements among them, subject to any statutory or regulatoryrequirements as may be in effect from time to time. Beneficial Owners of Securities may wish to takecertain steps to augment the transmission to them of notices of significant events with respect to theSecurities, such as redemptions, tenders, defaults, and proposed amendments to the Security documents.For example, Beneficial Owners of Securities may wish to ascertain that the nominee holding theSecurities for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In thealternative, Beneficial Owners may wish to provide their names and addresses to the registrar and requestthat copies of notices be provided directly to them.

Redemption notices shall be sent to DTC. If less than all of the Securities within an issue arebeing redeemed, DTC’s practice is to determine by lot the amount of the interest of each DirectParticipant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect toSecurities unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Underits usual procedures, DTC mails an Omnibus Proxy to the County as soon as possible after the recorddate. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants towhose accounts Securities are credited on the record date (identified in a listing attached to the OmnibusProxy).

Redemption proceeds, distributions, and dividend payments on the Securities will be made toCede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’spractice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detailinformation from the County or the Trustee, on payable date in accordance with their respective holdingsshown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standinginstructions and customary practices, as is the case with securities held for the accounts of customers inbearer form or registered in “street name,” and will be the responsibility of such Participant and not ofDTC, the Trustee, or the County, subject to any statutory or regulatory requirements as may be in effectfrom time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co.(or such other nominee as may be requested by an authorized representative of DTC) is the responsibilityof the County or the Trustee, disbursement of such payments to Direct Participants will be theresponsibility of DTC, and disbursement of such payments to the Beneficial Owners will be theresponsibility of Direct and Indirect Participants.

F-3

NONE OF THE COUNTY, THE CORPORATION OR THE TRUSTEE WILL HAVE ANYRESPONSIBILITY OR OBLIGATION TO DTC PARTICIPANTS, INDIRECT PARTICIPANTS ORBENEFICIAL OWNERS WITH RESPECT TO THE PAYMENTS OR THE PROVIDING OF NOTICETO DTC PARTICIPANTS, INDIRECT PARTICIPANTS OR BENEFICIAL OWNERS OR THESELECTION OF CERTIFICATES FOR PREPAYMENT.

Neither the County, the Corporation nor the Trustee can give any assurances that DTC, DTCParticipants, Indirect Participants or others will distribute payments of principal, premium, if any, andinterest evidenced by the Certificates paid to DTC or its nominee, as the registered Owner, or anyprepayment or other notice, to the Beneficial Owners or that they will do so on a timely basis or that DTCwill serve and act in a manner described in this Official Statement.

DTC may discontinue providing its services as depository with respect to the Securities at anytime by giving reasonable notice to the County or the Trustee. Under such circumstances, in the eventthat a successor depository is not obtained, Security certificates are required to be printed and delivered.

The County (at the Direction of the Corporation) may decide to discontinue use of the system ofbook-entry-only transfers through DTC (or a successor securities depository). In that event, Securitycertificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtainedfrom sources that the County believes to be reliable, but the County takes no responsibility for theaccuracy thereof.
