T-SQL EXEC command inside transaction

Question

I need to execute a store procedure from another with the common EXEC command. I need to be sure, that all the sql statements will be under transaction.

BEGIN TRANSACTION
BEGIN TRY   

    SET @Esercizio = (SELECT ESERCIZIO_OBIETTIVI_CONSUNTIVARE from TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE)
    SET @TipoProcesso = (SELECT ISNULL(TipoProcesso, 'middle') from TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE)

    DELETE FROM TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE
    DELETE FROM TB_SCHEDE_AUTOVAL WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE
    DELETE FROM TB_OBIETTIVI WHERE MATRICOLA = @iMATRICOLA and ESERCIZIO =  @Esercizio
    DELETE FROM TB_OBIETTIVI_AUTOVAL WHERE MATRICOLA = @iMATRICOLA and ESERCIZIO =  @Esercizio

    EXEC AnotherStore @iCOD_VALUTAZIONE, @iMATRICOLA, @TipoProcesso
    COMMIT TRANSACTION

END TRY
BEGIN CATCH
    ROLLBACK TRANSACTION
END CATCH

If the AnotherStore procedure throw an exception, does the DB engine ensure rollback from the caller store procedure?

Hope to be clear.

See Exception handling and nested transactions for an example of execption handling in the presence of transactions:

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
    end catch   
end
