the couplings $\lambda_1$ and $\lambda_2$ in (\[Wnu\]) must now be modified to reflect the fact that the Higgs doublets must also come from two different species. These are denoted in the same manner as the lepton doublets: $H_{1,2}$ for $(\mathbf{2},1)$ representations and $H'_{1,2}$ for $(1,\mathbf{2})$ representations. The second line in (\[Wfull\]) are the dynamically-generated supersymmetric mass terms, with $\lambda_3 \lang S_3 \rang \equiv M_T$. The fields $S_3$, $S_4$ and $S_5$ are singlets under $SU(2)_A \times SU(2)_B$ with hypercharge $Y=0$, while $\wh{S}_4$ and $\wh{S}_5$ are $SU(2)_L$ singlets with $Y=0$ transforming as $(\mathbf{2},\mathbf{2})$ under $SU(2)_A \times SU(2)_B$. We anticipate a large vev for $S_3$. The fields $S_4, S_5, \wh{S}_4$, and $\wh{S}_5$ may acquire TeV scale vevs from supersymmetry breaking, leading to generalized $\mu$ terms[^2], or some could have vevs near the string scale (or at an intermediate scale), projecting some of the Higgs states out of the low energy theory. From the point of view of both $SU(2)_L$ as well as the underlying $SU(2)_A \times
SU(2)_B$ it is not necessary that $S_4$ and $S_5$ be distinct fields; there may be string selection rules forbidding their identification in an explicit construction, however. Similar statements apply to $\wh{S}_4$ and $\wh{S}_5$. Of course, some of
