помогите, пожалуйста, перевести часть фразы (CHARGED UPON THE UNDERTAKING) ...что-то я запуталась в ней....

The Board may raise, or secure the payment or repayment of, such sum or sums in such manner and upon such terms and conditions in all respects as it thinks fit and, in particular, by the issue of debentures of the Company CHARGED UPON THE UNDERTAKING and all or any of the property (both present and future) and the uncalled capital of the Company for the time being.

Заранее огромное приогромное спасибо!
