July 18, 2001 Smith Barney Technology Fund 7 World Trade Center New York, New York 10048 Smith Barney Global Technology Fund 7 World Trade Center New York, New York 10048 Ladies and Gentlemen: You have asked us for our opinion concerning certain federal income tax consequences to (a) Smith Barney Technology Fund (the "Acquiring Fund") and Smith Barney Global Technology Fund (the "Acquired Fund"), each a separate series of Smith Barney Sector Series Inc., a Maryland corporation ("Sector Series"), and (b) holders ("Acquired Fund Shareholders") of voting shares of common stock of the Acquired Fund ("Acquired Fund Shares") when Acquired Fund Shareholders receive voting shares of common stock of the Acquiring Fund (the "Acquiring Fund Shares") in exchange for their Acquired Fund Shares pursuant to the acquisition by the Acquiring Fund of all of the assets of the Acquired Fund in exchange for the Acquiring Fund Shares and the assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund (the "Reorganization"), all pursuant to that certain Plan of Reorganization, dated July 18, 2001 (the "Plan"). We have reviewed such documents and materials as we have considered necessary for the purpose of rendering this opinion. In rendering this opinion, we have assumed that such documents as yet unexecuted will, when executed, conform in all material respects to the proposed forms of such documents that we have examined. In addition, we have assumed the genuineness of all signatures, the capacity of each party executing a document to so execute that document, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as certified or photostatic copies. We have made inquiry as to the underlying facts which we considered to be relevant to the conclusions set forth in this letter. The opinions expressed in this letter are based upon certain factual statements relating to the Acquiring Fund and the Acquired Fund set forth in the Registration Statement on Form N-14 (the "Registration Statement") filed by Sector Series with the Securities and Exchange Commission and representations made in letters from Sector Series, on behalf of the Acquiring Fund and the Acquired Fund, addressed to us for our use in rendering this opinion (the "Tax Representation Letters"). We have no reason to believe that these representations and facts are not valid, but we have not attempted to verify independently any of these representations and facts, and this opinion is based upon the assumption that each of them is accurate. Capitalized terms used herein and not otherwise defined shall have the meaning given them in the Registration Statement. The conclusions expressed herein are based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations issued thereunder, published rulings and procedures of the Internal Revenue Service and judicial decisions, all as in effect on the date of this letter. Based upon the foregoing, we are of the opinion that for federal income tax purposes: (a)	the Reorganization will constitute a "reorganization" within the meaning of Section 368(a)(1) of the Code, and the Acquiring Fund and the Acquired Fund will each be a "party to a reorganization" within the meaning of Section 368(b) of the Code; (b)	no gain or loss will be recognized by the Acquiring Fund on the receipt of the assets of the Acquired Fund in exchange for the Acquiring Fund Shares and the assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund; (c)	no gain or loss will be recognized by the Acquired Fund upon the transfer of the Acquired Fund's assets to the Acquiring Fund in exchange for the Acquiring Fund Shares and the assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund or upon the distribution (whether actual or constructive) of the Acquiring Fund Shares to the Acquired Fund Shareholders in exchange for their Acquired Fund Shares; (d)	no gain or loss will be recognized by the Acquired Fund Shareholders upon the exchange of their Acquired Fund Shares for the Acquiring Fund Shares or upon the assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund; (e)	the aggregate tax basis for the Acquiring Fund Shares received by each Acquired Fund Shareholder pursuant to the Reorganization will be the same as the aggregate tax basis of the Acquired Fund Shares held by such Acquired Fund Shareholder immediately prior to the Reorganization, and the holding period of the Acquiring Fund Shares to be received by each Acquired Fund Shareholder will include the period during which the Acquired Fund Shares exchanged therefor were held by such Acquired Fund Shareholder (provided that such Acquired Fund Shares were held as capital assets on the date of the Reorganization); and (f)	the tax basis of the Acquired Fund's assets acquired by the Acquiring Fund will be the same as the tax basis of such assets to the Acquired Fund immediately prior to the Reorganization, and the holding period of the assets of the Acquired Fund in the hands of the Acquiring Fund will include the period during which such assets were held by the Acquired Fund. Our opinion is based upon the accuracy of the certifications and warranties and the satisfaction of the covenants and obligations in the Plan, the Tax Representation Letters and the various documents relating thereto. Our opinion may not be relied upon if any such certifications, representations or warranties are not accurate or if any of such covenants or obligations are not satisfied in all material respects. Very truly yours, Willkie Farr & Gallagher 920849.1 	- 3 -
