Parameterized form of Zilber's conjecture on intersections with tori

Let KK be an algebraically closed field extending k0k_0, and let B=B(K)B=\mathbb{B}(K) be a semiabelian variety defined over a field k0k_0 of characteristic zero. For a subvariety W(x,y)W(x,y) of B1+kB^{1+k}, a point cBkc\in B^k, and a coset α+C\alpha+C of a proper algebraic subgroup CC of BB, let SS be an atypical component of the intersection of W(x,c)W(x,c) and α+C\alpha+C. Parameterized CIT. For every k0k\geq 0, every such W(x,y)W(x,y) defined over k0k_0, and every cBkc\in B^k, there exist a finite collection of proper algebraic subgroups C1,,CsC_1,\dots,C_s of BB and elements α1,,αrB\alpha^1,\dots,\alpha^r\in B such that, for every coset α+C\alpha+C, some i{1,,s}i\in\{1,\dots,s\} and j{1,,r}j\in\{1,\dots,r\} satisfy that SS is contained in αj+Ci\alpha^j+C_i and is a typical component of the intersection of W(x,c)W(x,c) and α+C\alpha+C with respect to αj+Ci\alpha^j+C_i. The source states that the original CIT implies this parameterized version in the multiplicative-group case; it gives no resolution status.
