Re:      Registration Statement on Form S-8
         ----------------------------------

Ladies and Gentlemen:

We have  acted as  counsel  for  Northeast  Indiana  Bancorp,  Inc.,  a Delaware
corporation (the "Company"),  in connection with the preparation and filing of a
Registration  Statement  on Form  S-8  (the  "Registration  Statement")  for the
registration  under the  Securities  Act of 1933,  as amended (the "Act"),  of a
total of 158,753 shares (the "Shares") of the Company's  common stock,  $.01 par
value per share  (the  "Common  Stock"),  which  may be issued  pursuant  to the
Company's  2002  Omnibus  Incentive  Plan (the  "Plan").  This  opinion is being
furnished in accordance  with the  requirements  of Item 601(b)(5) of Regulation
S-K under the Act.

In connection  with this opinion,  we have examined and relied upon originals or
copies, certified or otherwise identified to our satisfaction, of the following:

1.       The Registration Statement;

2.       The Certificate of Incorporation of the Company;

3.       The By-laws of the Company;

4.       Records of proceedings and actions of the Board of Directors of the
         Company relating to the Plan and the Registration  Statement;

5.       The Plan;

6.       The form of specimen certificate representing the Common Stock; and

7.       Such other instruments, documents, statements and records of the
         Company and others as we have deemed relevant and necessary to examine
         and rely upon for the purpose of this opinion.

In connection with this opinion,  we have assumed the accuracy and  completeness
of all  documents  and records that we have  reviewed,  the  genuineness  of all
signatures, the authenticity





of the documents  submitted to us as originals  and the  conformity to authentic
original documents of all documents  submitted to us as certified,  conformed or
reproduced  copies. We have further assumed that all natural persons involved in
the  transactions  contemplated by the  Registration  Statement (the "Offering")
have  sufficient  legal  capacity  to enter into and  perform  their  respective
obligations and to carry out their roles in the Offering.

Based  upon  the  foregoing,  we are  of  the  opinion  that  when  certificates
representing the Shares in the form of the specimen  certificate  examined by us
have been  manually  signed by an authorized  officer of the transfer  agent and
registrar for the Common Stock or registered and issued  electronically  through
The Depository  Trust Company,  and when such Shares are issued and delivered by
the Company and paid for in accordance with the terms of the Plan, up to 158,753
Shares issuable under the Plan and covered by the Registration Statement will be
validly issued, fully paid and nonassessable securities of the Company.

Our opinion  expressed  above is limited to the General  Corporation  Law of the
State of Delaware,  the applicable  provisions of the Delaware  Constitution and
the reported  judicial  decisions  interpreting such laws, and we do not express
any opinion herein concerning any other laws. In addition, we express no opinion
herein concerning any statutes,  ordinances,  administrative decisions, rules or
regulations of any county, town,  municipality or special political  subdivision
(whether created or enabled through legislative action at the federal,  state or
regional  level).  This  opinion is given as of the date hereof and we assume no
obligation  to advise  you of  changes  that may  hereafter  be  brought  to our
attention. In connection therewith, we hereby consent to the use of this opinion
for filing as Exhibit 5 to the Registration Statement.

In giving  this  consent,  we do not thereby  admit that we are  included in the
category of persons whose consent is required  under Section 7 of the Act or the
related rules and regulations thereunder.

Very truly yours,
