FOR IMMEDIATE RELEASE

MICHAEL FOODS AND NORTH STAR UNIVERSAL TO CLOSE MERGER BASED ON TAX OPINION
- ---------------------------------------------------------------------------

MINNEAPOLIS, December 23 -- Michael Foods, Inc. ("MFI") (Nasdaq\NMS:MIKL) and 
North Star Universal, Inc. ("NSU") (Nasdaq\NMS:NSRU) jointly announced today
that due to continuing delays with the Internal Revenue Service ("IRS"), they
have elected to proceed with the merger of the companies based upon the receipt
of a mutually acceptable opinion of certified public accountants as to the tax
consequences of the transactions. As a result, the parties will withdraw a
revenue ruling request that was filed nearly one year ago with the IRS. In a
recent meeting with the IRS, the companies learned that it could take another
six months, or longer, for the IRS to complete the ruling request process.

It is expected that the tax opinion will be obtained in early 1997 and that the
transactions affecting the merger of the companies will close in the first
quarter of 1997, pending stockholder approvals and other closing conditions.
Both MFI and NSU are holding stockholder meetings on December 30, 1996.

As background, MFI and NSU previously announced that they had entered into an
agreement which provides for a series of transactions. First, MFI will purchase
and retire a portion of NSU's stock holdings in MFI by assuming NSU's net
outstanding debt. NSU's remaining MFI stock holdings will be allocated pro rata
to NSU's shareholders. The repurchase transaction will be accomplished through
a business combination of MFI and NSU. In conjunction with this, ENStar Inc., a
wholly-owned subsidiary of NSU, will hold NSU's non-food assets, including its
computer networking companies, Americable, Inc. and Transition Networks, and an
equity holding in CorVel Corporation. In the second part of the series of
transactions, shares of ENStar Inc. will be spun-off to NSU's shareholders and
will be publicly traded after the spin-off. The tax opinion will relate to the
tax-free nature of the business combination and spin-off.
