Hamm, who is chairman of both companies, upped his offer Monday for shares of Hiland Partners LP and Hiland Holdings GP LP.
Hamm is trying to buy all of the shares he does not own so he can take the companies private.
Shareholders were scheduled to vote on the proposal today, but meetings for both companies were adjourned until next week to allow the companies' boards of directors and conflict committees to consider Hamm's new offer.
Hamm is offering $10 per Hiland Partners share and $3.20 per Hiland Holdings share. His original offer was $7.50 for Hiland Partners shares and $2.40 for Hiland Holdings shares.
The meetings were reset for next Tuesday.
