Item 1.01 Material Definitive Agreement.

MFB Corp.'s wholly owned banking subsidiary, MFB Financial, and Mellinger
Financial Services, Inc., operator of Northwestern Mutual Financial
Network-South Bend ("Tenant"), have entered into a lease agreement as of
February 2, 2005. MFB Financial will lease to Tenant approximately 15,000 square
feet on the second floor of MFB Corp.'s corporate headquarters located in the
Edison Lakes office park in Mishawaka, Indiana.

The lease term extends for 84 months, or 7 years, commencing when the space is
built out and delivered to Tenant, anticipated to occur in May 2005. The term
may be renewed by the Tenant for 2 additional 5-year terms, with an agreed-upon
increase in rent, provided that the Tenant is not in default under the lease.
MFB Financial has also granted the Tenant a right of first refusal to additional
space contiguous to its leased space, if it becomes available.

In addition to basic rent payable to MFB Financial monthly during the lease
term, the Tenant has agreed to pay additional rent in the form of the Tenant's
percentage share of the operating costs of the building.

Both MFB Financial and the Tenanat have undertaken specific responsibilities
under the terms and conditions of the lease, such as MFB Financial's obligations
as a landlord to maintain the building and the leased premises in an appropriate
manner, and a default by either party of these obligations may lead to
cancellation of the lease and or other remedies available at law or in the lease
agreement. In addition, each party has agreed to indemnify and hold the other
party harmless from losses caused by or suffered as a result of violations of
the lease obligations.

Tenant is the general agent for a sales territory for The Northwestern Life
Insurance Company, a Wisconsin corporation ("Northwestern Life"). MFB Financial,
the Tenant and Northwestern Life have entered into an agreement supplemental and
attached to the lease agreement pursuant to which the parties agree that the
Tenant may voluntarily assign the lease to Northwestern Life or to any successor
general agent for the sales territory, and the assignee will assume and continue
to be obligated to MFB Financial under the lease. Further, if for any reason the
Tenant's agreement to serve as a general agent for Northwestern Life is
terminated, then Northwestern Life or the successor general agent will
automatically be assigned and assume the lease obligations to MFB Financial.

In addition, The Northwestern Mutual Life Insurance Company, a Wisconsin
corporation ("Northwestern Mutual") has, as a condition to the lease, executed
and delivered a Lease Guaranty in favor of MFB Financial. Northwestern Mutual
irrevocably guarantees to MFB Financial the full and prompt payment and
performance by Tenant (including Northwestern Life or any successor general
agent which becomes the Tenant by assignment) of the obligations under the
lease, to the extent those obligations are not increased or expanded by any
options or other actions of the Tenant.

MFB Financial announced the lease agreement in a press release dated February 2,
2005, a copy of which is attached as Exhibit 99.1 to this Current Report on Form
8-K.
