A light CP-even Higgs boson (h) with a mass of about 10 GeV could explain therecent BNL measurement of the muon anomalous magnetic moment, in the frameworkof a general CP-conserving two-Higgs-doublet extension of the Standard Modelwith no tree-level flavor-changing neutral Higgs couplings. However, theallowed Higgs mass window is quite small and the corresponding model parametersare very constrained. The Higgs sector can contribute significantly to theobserved BNL result for g-2 without violating known experimental constraintsonly if the hZZ coupling (approximately) vanishes and m_h lies between theUpsilon mass and 2m_B.Comment: 16 pages, 1 figure, JHEP style, typographical errors and one reference corrected, a new footnote, paragraph and one new reference adde
