                                   PROMISSORY NOTE

$1,500,000.00                                                 Chicago, Illinois
                                                                  April 9, 1998


     FOR VALUE RECEIVED, the undersigned, FAMCO III LIMITED LIABILITY 
COMPANY, a Delaware limited liability company (the "Borrower"), promises to 
pay to the order of [name of bank omitted pursuant to Item 3 of Schedule 13D] 
the principal sum of One Million Five Hundred Thousand and no/100 Dollars 
($1,500,000.00) on July 18, 1998.  The borrower further promises to pay 
interest at such office on the balance of principal remaining from time to 
time unpaid hereon at the rates and times set forth in this Note.

SECTION 1.     APPOINTMENT OF FISCAL AGENT.

     The Borrower hereby irrevocably appoints Family Financial Strategies, 
Inc. ("FFS") as his/her fiscal agent for the purpose of receiving all notices 
hereunder and selecting interest rates and interest options available to the 
Borrower hereunder.  The Bank is hereby authorized and directed to follow all 
instructions of FFS with respect to all matters concerning this Note and to 
give to FFS all notices hereunder or with respect to the Collateral, all of 
which shall be binding upon the Borrower.  The Borrower hereby indemnifies 
the Bank from any liability or loss ensuing from the Bank's reliance upon 
such instructions and notices.  The Borrower acknowledges that FFS serves in 
a similar role of fiscal agent for other participating Bell family members 
under a Bank mortgage loan program, and that the interest rate alternatives 
available under this Note shall be exercised on behalf of the Borrower by FFS 
on a common and uniform basis for all or substantially all borrowers 
participating under this program.

SECTION 2.     INTEREST AND CHANGE IN CIRCUMSTANCES.

     SECTION 2.1.   INTEREST RATE OPTIONS. (a) Subject to all of the terms 
and conditions of this Section 2, portions of the principal indebtedness 
evidenced by this Note (all of the indebtedness evidenced by this Note 
bearing interest at the same rate for the same period of time being 
hereinafter referred to as a "PORTION") may, at the option of FFS acting on 
behalf of the Borrower, bear interest with reference to the Domestic Rate 
(the "DOMESTIC RATE PORTION") or with reference to the Adjusted LIBOR Rate 
("LIBOR PORTIONS"), and Portions may be converted from time to time from one 
basis to another.  The interest rate applicable to this Note will never be 
greater than 25% (the "MAXIMUM RATE"). All of the indebtedness evidenced by 
this Note which is not part of a LIBOR Portion shall constitute a single 
Domestic Rate Portion, and all of the indebtedness evidenced by the Note 
which bears interest with reference to a particular Adjusted LIBOR Rate for a 
particular Interest Period shall constitute a single LIBOR Portion.  Anything 
contained herein to the contrary notwithstanding, there shall not be more 
than one LIBOR Portion applicable to this Note outstanding at any one time.  

                                   Page 8 of 87 Pages
<PAGE>

The Borrower promises to pay interest on each Portion at the rates and times 
specified in this Section 2.

     (b)  DOMESTIC RATE PORTION.  The Domestic Rate Portion shall bear 
interest at the rate per annum determined by subtracting the rate of 1/2 of 
1% per annum from the Domestic Rate, provided that if the Domestic Rate 
Portion or any part thereof is not paid when due (whether by lapse of time, 
acceleration or otherwise) such Portion shall bear interest, whether before 
or after judgment, until payment in full thereof at the rate per annum 
determined by adding 2% to the Domestic Rate which would otherwise be 
applicable thereto from time to time. Interest on the Domestic Rate Portion 
shall be payable monthly in arrears on the last day of each month and at 
maturity of this Note and interest after maturity shall be due and payable 
upon demand.

     (c)  LIBOR PORTIONS.  Each LIBOR Portion shall bear interest for each 
Interest Period selected therefor at a rate per annum determined by adding 
 .70% to the Adjusted LIBOR Rate for such Interest Period, provided that if 
any LIBOR Portion is not paid when due (whether by lapse of time, 
acceleration or otherwise) such Portion shall bear interest, whether before 
or after judgment, until payment in full thereof through the end of the 
Interest Period then applicable thereto at the rate per annum determined by 
adding 2% to the interest rate which would otherwise be applicable thereto, 
and effective at the end of such Interest Period such LIBOR Portion shall 
automatically be converted into and added to the Domestic Rate Portion and 
shall thereafter bear interest at the interest rate applicable to the 
Domestic Rate Portion after default.  Interest on each LIBOR Portion shall be 
due and payable on the last day of each month and at maturity (whether by 
lapse of time, acceleration or otherwise) and interest after maturity shall 
be due and payable upon demand.  Anything contained herein to the contrary 
notwithstanding, the obligation of the Bank to create, continue or effect by 
conversion any LIBOR Portion shall be conditioned upon the fact that at the 
time no Default or Event of Default shall have occurred and be continuing, 
and that the interest rate under this subsection (c) does not exceed the 
Maximum Rate.  Each LIBOR Portion under this Note and other loans outstanding 
under the Bell family program referred to in Section 1 shall be in a minimum 
amount of $1,000,000 or such greater amount which is an integral multiple of 
$100,000.

     SECTION 2.2.   COMPUTATION OF INTEREST.  All interest on the LIBOR 
Portions of this Note shall be computed on the basis of a year of 360 days 
for the actual number of days elapsed, and all interest on the Domestic Rate 
Portion of this Note shall be computed on the basis of a year of 360 days for 
the actual number of days elapsed.

     SECTION 2.3.   MANNER OF RATE SELECTION.  FFS acting on behalf of the 
Borrower shall notify the Bank (i) by 10:00 a.m. (Chicago time) at least 
three (3) Business Days prior to the date upon which it requests that any 
LIBOR Portion be created or that any part of the Domestic Rate Portion be 
converted into a LIBOR Portion, and (ii) by 10:00 a.m. (Chicago time) on the 
date upon which it requests that any Domestic Rate Portion be created or that 
any part of a LIBOR Portion be converted into a Domestic Rate Portion (each 
such notice to specify in each instance the amount thereof and the Interest 
Period selected therefor).  If FFS fails to notify the Bank on or before 
10:00 a.m. (Chicago time) on the third Business Day preceding the end of an 
Interest Period applicable to a LIBOR Portion whether such LIBOR Portion is 
to continue as a LIBOR Portion and the new Interest Period selected therefor, 
such LIBOR Portion shall automatically be converted into and 

                                  Page 9 of 87 Pages
<PAGE>

added to the Domestic Rate Portion as of and on the last day of such Interest 
Period.  If any request is made to convert a LIBOR Portion into another type 
of Portion available hereunder, such conversion shall only be made so as to 
become effective as of the last day of the Interest Period applicable 
thereto.  All requests for the creation, continuance or conversion of 
Portions under this Note shall be irrevocable. Such requests may be written 
or oral and the Bank is hereby authorized to honor telephonic requests for 
creations, continuances and conversions received by it from any person the 
Bank in good faith believes to be a person authorized to act on behalf of the 
borrower hereunder, the Borrower hereby indemnifying the Bank from any 
liability or loss ensuing from so acting.

     SECTION 2.4.   CHANGE OF LAW.  Notwithstanding any other provisions of 
this Note, if at any time the Bank shall determine in good faith that any 
change in applicable laws, treaties or regulations or in the interpretation 
thereof makes it unlawful for the Bank to create or continue to maintain any 
LIBOR Portion, it shall promptly so notify FFS on behalf of the Borrower and 
the obligation of the Bank to create, continue or maintain such LIBOR Portion 
under this Note shall terminate as of the date of such determination until it 
is no longer unlawful for the Bank to create, continue or maintain such LIBOR 
Portion.  Upon receipt of such notice from the Bank the Borrower shall, if 
the continued maintenance of any LIBOR Portion is unlawful, thereupon prepay 
the outstanding principal amount of the affected LIBOR Portion, together with 
all interest accrued thereon and all other amounts payable to the Bank with 
respect thereto under this Agreement; provided, however, that FFS on behalf 
of the Borrower may elect to convert the principal amount of the affected 
Portion into the Domestic Rate Portion available hereunder, subject to the 
terms and conditions of this Note.

     SECTION 2.5.   UNAVAILABILITY OF DEPOSITS OR INABILITY TO ASCERTAIN 
LIBOR OR ADJUSTED LIBOR RATE.  Notwithstanding any other provision of this 
Note, if prior to the commencement of any Interest Period, the Bank shall 
determine that deposits in the amount of any LIBOR Portion scheduled to be 
outstanding during such Interest Period are not readily available to the Bank 
in the relevant market or by reason of circumstances affecting the relevant 
market, adequate and reasonable means do not exist for ascertaining LIBOR or 
the Adjusted LIBOR Rate, then the Bank shall promptly give notice thereof to 
FFS on behalf of the Borrower and the obligations of the Bank to create, 
continue or effect by conversion any LIBOR Portion, as the case may be, in 
such amount and for such Interest Period shall terminate until deposits in 
such amount and for the Interest Period selected by FFS on behalf of the 
Borrower shall again be readily available in the relevant market and adequate 
and reasonable means exist for ascertaining LIBOR or Adjusted LIBOR Rate, as 
the case may be.

     SECTION 2.6.   TAXES AND INCREASED COSTS.  With respect to any LIBOR 
Portion, if the Bank shall determine in good faith that any change in any 
applicable law, treaty, regulation or guideline (including, without 
limitation, Regulation D of the Board of Governors of the Federal Reserve 
System) or any new law, treaty, regulation or guideline, or any 
interpretation of any of the foregoing by any governmental authority charged 
with the administration thereof or any central bank or other fiscal, monetary 
or other authority having jurisdiction over the Bank or its lending branch or 
the LIBOR Portions contemplated by this Note (whether or not having the force 
of law) shall:

                                  Page 10 of 87 Pages
<PAGE>

          (i)       impose, increase, or deem applicable any reserve, special 
     deposit or similar requirement against assets held by, or deposits in or 
     for the account of, or loans by, or any other acquisition of funds or 
     disbursements by, the Bank which is not in any instance already 
     accounted for in computing the interest rate applicable to such LIBOR 
     Portion;

          (ii)      subject the Bank, any LIBOR Portion or this Note to the 
     extent it evidences such Portion, to any tax (including, without 
     limitation, any United States interest equalization tax or similar tax 
     however named applicable to the acquisition or holding of debt 
     obligations and any interest or penalties with respect thereto), duty, 
     charge, stamp tax, fee, deduction or withholding in respect of any LIBOR 
     Portion or this Note to the extent it evidences such Portion, except 
     such taxes as may be measured by the overall net income or gross 
     receipts of the Bank or its lending branches and imposed by the 
     jurisdiction, or any political subdivision or taxing authority thereof, 
     in which the Bank's principal executive office or its lending branch is 
     located;

          (iii)     change the basis of taxation of payments of principal and 
     interest due from the Borrower to the Bank under this Note to the extent 
     it evidences any LIBOR Portion (other than by a change in taxation of 
     the overall net income or gross receipts of the Bank); or

          (iv)      impose on the Bank any penalty with respect to the 
     foregoing or any other condition regarding its disbursement, any LIBOR 
     Portion or this Note to the extent it evidences any LIBOR Portion;

and the Bank shall determine that the result of any of the foregoing is to 
increase the cost (whether by incurring a cost or adding to a cost) to the 
Bank of creating or maintaining any LIBOR Portion hereunder or to reduce the 
amount of principal or interest received or receivable by the Bank (without 
benefit of, or credit for, any prorations, exemption, credits, or other 
offsets available under any such laws, treaties, regulations, guidelines or 
interpretations thereof), then the Borrower shall pay on demand to the Bank 
from time to time as specified by the Bank such additional amounts as the 
Bank shall reasonably determine are sufficient to compensate and indemnify it 
for such increased cost or reduced amount.  If the Bank makes such a claim 
for compensation, it shall provide to FFS on behalf of the Borrower a 
certificate setting for the computation of the increased cost or reduced 
amount as a result of any event mentioned herein in reasonable detail and 
such certificate shall be conclusive if reasonably determined.

     SECTION 2.7.   FUNDING INDEMNITY.  In the event the Bank shall incur any 
loss, cost or expense (including, without limitation, any loss, cost or 
expense incurred by reason of the liquidation or reemployment of deposits or 
other funds acquired or contracted to be acquired by the Bank to fund or 
maintain any LIBOR Portion or the relending or reinvesting of such deposits 
or other funds or amounts paid or prepaid to the Bank) as a result of any 
failure by the Borrower to create, borrow, continue or affect by conversion a 
LIBOR Portion on the date specified in a notice given pursuant to this Note, 
then upon the demand of the Bank, the Borrower shall pay to the Bank such 
amount as will reimburse the Bank for such loss, cost or expense.  If the 
Bank requests such a reimbursement it shall provide to FFS on behalf of the 
Borrower with a certificate setting forth the computation of 
                                       
                              Page 11 of 87 Pages
<PAGE>

the loss, cost or expense giving rise to the request for reimbursement in 
reasonable detail and such certificate shall be conclusive if reasonably 
determined.

     SECTION 2.8.   LENDING BRANCH.  The Bank may, at its option, elect to 
make, fund or maintain Portions of the loan hereunder at such of its branches 
or offices as the Bank may from time to time elect.

     SECTION 2.9.   DISCRETION OF BANK AS TO MANNER OF FUNDING.  
Notwithstanding any provision of this Note to the contrary, the Bank shall be 
entitled to fund and maintain its funding of all or any part of this Note in 
any manner it sees fit, it being understood, however, that for the purposes 
of this Note all determinations hereunder shall be made as if the Bank had 
actually funded and maintained each LIBOR Portion during each Interest Period 
applicable thereto through the purchase of deposits in the relevant market in 
the amount of such LIBOR Portion, having a maturity corresponding to such 
Interest Period and bearing an interest rate equal to the interest rate 
applicable to such LIBOR Portion for such Interest Period.

SECTION 3.     NOTATIONS AND REQUESTS.

     The loan made against this Note, the status of all amounts evidenced by 
this Note as constituting part of the Domestic Rate Portion or a LIBOR 
Portion, and the rates of interest and Interest Periods applicable to such 
Portions shall be recorded by the Bank on its books and records or, at its 
option in any instance, endorsed on a schedule to this Note and the unpaid 
principal balance and status, rates and Interest Periods so recorded or 
endorsed by the Bank shall be PRIMA FACIE evidence in any court or other 
proceeding brought to enforce this Note of the principal amount remaining 
unpaid thereon, the status of the loan evidenced thereby and the interest 
rates and Interest Periods applicable thereto; provided, however, that the 
failure of the Bank to record any of the foregoing shall not limit or 
otherwise affect the obligation of the Borrower to repay the principal amount 
of this Note together with accrued interest thereon. Prior to any negotiation 
of this Note, the Bank shall record on a schedule thereto the status of all 
amounts evidenced thereby as constituting part of the Domestic Rate Portion 
or LIBOR Portion and the rates of interest and the Interest Periods 
applicable thereto.

SECTION 4.     REPRESENTATIONS AND WARRANTIES.

     The Borrower represents and warrants to the Bank that this Note does not 
nor will the performance or observance by the Borrower of any of the matters 
and things herein provided contravene any provision of law or any instrument 
or agreement which affects the Borrower or any of its assets.  The Borrower 
is not engaged in the business of extending credit for the purpose of 
purchasing or carrying margin stocks (within the meaning of Regulation U of 
the Board of Governors of the Federal Reserve System) and no part of the 
proceeds of the loan evidenced hereby will be used to purchase or carry any 
margin stock or extend credit to others for the purpose of purchasing or 
carrying any margin stock.

SECTION 5.     THE COLLATERAL.

                                Page 12 of 87 Pages
<PAGE>

     This Note shall at all times be secured by first liens on certain 
residential real property of the Borrower and on readily marketable 
investment securities acceptable to the Bank (the "COLLATERAL") which shall 
be pledged to the Bank by either the Borrower or FFS on behalf of the 
Borrower pursuant to documentation acceptable to the Bank in form and 
substance (the "SECURITY DOCUMENTS").  The Bank shall have the right to call 
for additional security satisfactory to it should the value of the marketable 
investment securities portion of the Collateral decline or be deemed by the 
Bank inadequate or unsatisfactory.  The Borrower understands the Bank 
determined that the securities to be deposited initially with it by the 
Borrower or FFS must consist of readily marketable and freely tradeable 
securities acceptable to the Bank in an amount such that the total principal 
amount outstanding hereunder shall at no time exceed 50% of the fair market 
value thereof (as determined by the Bank) but the Borrower acknowledges and 
agrees that the Bank may by notice to FFS on behalf of the Borrower require a 
higher collateral coverage or require substitute collateral in the event that 
any security deposited with the Bank is not longer satisfactory to it.

                                       100%-Reserve Percentage

     "RESERVE PERCENTAGE" shall mean, for the purpose of computing the 
Adjusted LIBOR Rate, the maximum rate of all reserve requirements (including, 
without limitation, any marginal emergency, supplemental or other special 
reserves) imposed by the Board of Governors of the Federal Reserve System (or 
any successor) under Regulation D on Eurocurrency liabilities (as such term 
is defined in Regulation D) for the applicable Interest Period as of the 
first day of such Interest Period, but subject to any amendments to such 
reserve requirement by such Board or its successor, and taking into account 
any transitional adjustments thereto becoming effective during such Interest 
Period. For purposes of this definition, LIBOR Portions shall be deemed to be 
Eurocurrency liabilities as defined in Regulation D without benefit of or 
credit for prorations, exemptions or offsets under Regulation D.  "LIBOR" 
means, for an Interest Period,(a) the LIBOR Index Rate for such Interest 
Period, if such rate is available, and (b) if the LIBOR  Index Rate cannot be 
determined, the arithmetic average of the rates of interest per annum 
(rounded upwards, if necessary, to nearest 1/100 of 1%) at which deposits in 
U.S. dollars in immediately available funds are offered to the Agent at 11:00 
a.m. (London, England time) two (2) Business Days before the beginning of 
such Interest Period by three (3) or more major banks in the interbank 
eurodollar market selected by the Bank for a period equal to such Interest 
Period and in an amount equal or comparable to the principal amount of the 
LIBOR Portion scheduled to be made available by the Bank.

     "LIBOR INDEX RATE" means, for any Interest Period, the rate per annum 
(rounded upwards, if necessary, to the next higher one hundred-thousandth of 
a percentage point) for deposits in U.S. Dollars for a period equal to such 
Interest Period, which appears on the Telerate Page 3750 as of 11:00 a.m. 
(London, England time) on the day two Business Days before the commencement 
of such Interest Period.

     "TELERATE PAGE 3750" means the display designated as "PAGE 3750" on the 
Dow Jones Telerate Service (or such other page as may replace Page 3750 on

Bankers' Association as the information vendor for the purpose of displaying 
British Bankers' Association Interest Settlement Rates for U.S. Dollar 
deposits).

     "BUSINESS DAY" means a day on which the Bank is open for business in 
Chicago, Illinois other than a Saturday or Sunday and, when used with respect

     "COLLATERAL" means all of the real and personal property security for 
this Note provided to the Bank from time to time whether by the Borrower or 
others.

     "DEFAULT" means an event which with the passage of time, giving of

     "DOMESTIC RATE" shall mean a variable interest rate which may change
monthly, and for any calendar month shall be equal to the highest prime rate as
published in the Money Rates section of THE WALL STREET JOURNAL on the first
business day of that calendar month.  In the event THE WALL 

                               Page 15 of 87 Pages
<PAGE>

STREET JOURNAL does not publish a prime rate, the Bank may substitute a 
comparable, readily ascertainable index.

     "EVENT OF DEFAULT" means any of the events or conditions specified as 
such in Section 6 hereof.

     "INTEREST PERIOD" shall mean, with respect to any LIBOR Portion, the 
period commencing on, as the case may be, the creation, continuation or 
conversion date with respect to such LIBOR Portion and ending one (1), three 
(3) or six (6) months thereafter as selected by the Borrower in its notice as 
provided herein; PROVIDED THAT, all of the foregoing provisions relating to 
Interest Periods are subject to the following:

          (i)       if any Interest Period would otherwise end on a day which 
     is not a Business Day, that Interest Period shall be extended to the 
     next succeeding Business Day, unless in the case of an Interest Period 
     for a LIBOR Portion the result of such extension would be to carry such 
     Interest Period into another calendar month in which event such Interest 
     Period shall end on the immediately preceding Business Day;

          (ii)      no Interest Period may extend beyond the final maturity 
     date of this Note; and

          (iii)     the interest rate to be applicable to each Portion for 
     each Interest Period shall apply from and including the first day of 
     such Interest Period to but excluding the last day thereof.

For purposes of determining an Interest Period, a month means a period 
starting on one day in a calendar month and ending on a numerically 
corresponding day in the next calendar month, provided, however, if an 
Interest Period begins on the last day of a month or if there is no 
numerically corresponding day in the month in which an Interest Period is to 
end, then such Interest Period shall end on the last Business Day of such 
month.

     "SECURITY DOCUMENTS" means collectively any agreements now or hereafter 
executed and delivered to the Bank in respect of the Collateral.

SECTION 8.     MISCELLANEOUS.

     SECTION 8.1.   NO WAIVER OF RIGHTS.  No delay or failure on the part of 
the Bank or on the part of the holder or holders of the Note in the exercise

partial exercise of any power or right preclude any other or further exercise 
thereof, or the exercise of any other power or right, and the rights and 
remedies hereunder of the Bank and of the holder or holders of the Note are 
cumulative to, and not exclusive of, any rights or remedies which any of them 
would otherwise have.

     SECTION 8.2.   HOLIDAYS. (a)  If any payment of principal or interest on
the Domestic Rate Portion shall fall due on a day which is not a Business Day,
the payment date thereof shall be 

                               Page 16 of 87 Pages
<PAGE>

extended to the next Business Day and interest at the rate such Portion bears 
for the period prior to maturity shall continue to accrue on such principal 
from the stated due date thereof to and including the next succeeding 
Business Day on which the same is payable.

     (b)  If any payment of principal or interest on any LIBOR Portion shall 
fall due on a day which is not a Business Day, the payment date thereof shall 
be extended to the next date which is a Business day and the Interest Period 
for such Portion shall be accordingly extended, unless as result thereof any 
payment date would fall in the next calendar month, in which case such 
payment date shall be the next preceding Business Day and the relevant 
Interest Period shall be correspondingly abbreviated.  In either case, the 
next Interest Period shall be measured from the payment date so adjusted.

     SECTION 8.3.   COSTS AND EXPENSES.  The Borrower agrees to pay on demand 
all of the reasonable costs and expenses of the Bank in connection with the

Note in connection with the enforcement of this Note and the other

endeavoring to preserve, protect, perfect or realize upon the Collateral.

     SECTION 8.4.   SURVIVAL OF INDEMNITIES.  All indemnities and other 
provisions relative to reimbursement to the Bank of amounts sufficient to

          13.2      QUALIFICATION.  The Company is duly qualified or licensed 
as a foreign corporation in good standing in each jurisdiction wherein the 
nature of its activities or of its properties owned or leased makes such

licensed would have a material adverse impact on its business.

          13.3      CORPORATE ACTS AND PROCEEDINGS.  This Agreement has been
duly authorized by all necessary corporate action on behalf of the Company, and
will be duly executed and delivered by authorized officers of the Company.  All
corporate action necessary for the authorization, creation, issuance and

nature (whether absolute, accrued or contingent and whether due or to become 
due) of the Company as of their respective dates which, individually or in 
the aggregate, are material and which in accordance with generally accepted 
accounting principles would be required to be disclosed in such balance 
sheet, and the omission of which would, in the aggregate, have a material 
adverse impact on the Company.  The December 31, 1997 balance sheet includes

has been audited by governmental authorities in a manner to bring such audits 
to the Company's attention.  The Company does not have any tax liabilities 
except those reflected in the financial statements contained in its most 
recent 10-QSB Report filed with the Commission for the period ending on

The business and operations of the Company have been and are being conducted 
in accordance with all applicable laws, rules and regulations of all 
governmental authorities.  To the knowledge of the Company, neither the 
execution nor delivery of, nor the performance of or compliance with, this 
Agreement nor the consummation of the transactions contemplated hereby will 
conflict with, or, with or without the giving of notice or passage of time, 
result in any breach of, or constitute a default under, or result in the 
imposition of any lien or encumbrance upon any asset or property of the 
Company pursuant to, any applicable law, administrative regulation or 
judgment, order or decree of any court or governmental body, any agreement or 
other instrument to which the Company is a party or by which it or any of its 
properties, assets or rights is bound or affected, and will not violate the 
Articles of Incorporation or Bylaws of the Company.  The Company is not in 
violation of its Articles of Incorporation or its Bylaws nor, in violation 
of, or in default under, any lien, indenture, mortgage, lease, agreement, 
instrument, commitment or arrangement in any material respect.  To the 
knowledge of the Company all parties having material contractual arrangements 
with the Company are in substantial compliance therewith and none are in 
material default in any respect thereunder.

          13.10     PREFERRED SHARES AND CONVERSION STOCK; WARRANT STOCK.

and restrictions, except as set forth in Section 4 hereof, and  the shares of 
Conversion Stock and Warrant Stock issuable upon conversion of the Preferred 
Shares or exercise of the Warrants have been reserved for issuance based upon

conversion or exercise will be duly authorized, validly issued and 
outstanding, fully paid, nonassessable and free and clear of all pledges, 
liens, encumbrances and restrictions, except as set forth in Section 4

by the Company hereunder, and the certificates representing the Conversion 
Stock and Warrant Stock to be delivered upon the conversion of the Preferred 
Shares or exercise of the Warrants, will be genuine, and the Company has no 
knowledge of any fact which would impair the validity thereof. "Conversion 
Price" shall mean such price at which the Preferred Shares are convertible 
into Common Stock pursuant to the Certificate of Designation.

          13.11     GOVERNMENTAL CONSENTS.  Based in part upon the

authorization, approval, permit or order of or filing with any governmental

of the 

                               Page 25 of 87 Pages
<PAGE>

Conversion Stock or the Warrant Stock other than the qualification thereof, 
if required, under applicable state securities laws, which qualification has 
been or will be effected as a condition of these sales.  Under the 
circumstances contemplated hereby, the offer, issuance, sale and delivery of 
the Preferred Shares, the Warrants, the Conversion Stock and the Warrant 
Stock will not under current laws and regulations require compliance with the 
prospectus delivery or registration requirements of the Securities Act.

          13.12     CAPITAL STOCK.  The authorized capital stock of the 
Company consists of 12,500,000 shares, of which 10,000,000 are designated as 
common shares, with a par value of $.08 per share (the "Common Stock"), and 
2,500,000 are designated as preferred shares, with a par value of $.08 per

("Series I Preferred Stock") and 400,000 shares are designated as Series III 
Convertible Preferred Stock ("Series III Preferred Stock").  In addition, the 
Company has 127,600 shares of Common Stock reserved for issuance under its 
1988 Stock Option Plan (the "Plan").  All outstanding shares of Common Stock 
and Series I Preferred Stock have been duly authorized and validly issued and 
are fully paid and nonassessable.  Schedule 5.12A sets forth the Company's 
currently outstanding, reserved, and committed capital stock, options, shares 
reserved for issuance under the Plan, warrants, and the Company's 10% 
Convertible Debentures issued in September 1992 and originally due October 1, 
1995, and 10% Series B Debentures issued May 1993 and originally due May 1,

exchangeable for Common Stock or Preferred Stock, no contracts, rights, 
options, warrants or other agreements or commitments to purchase or otherwise 
acquire any shares of its capital stock or securities convertible into or 
exchangeable therefor, or any shares reserved for issuance under stock 
option, employee benefit or other plans or otherwise. Except as provided in 
the Certificate of Designation or otherwise required by law, all shares of 
capital stock of the Company vote as a single class on all matters submitted 
to the Company's shareholders.  Schedule 5.12B sets forth the Company's 
outstanding, reserved, and committed capital stock, options, shares reserved 
for issuance under the Plan, warrants, and Debentures after the Closing.  
There currently are no shares of  Series II Preferred Stock authorized and 
available for issuance.

          13.13     NO BROKERS OR FINDERS.  No person, firm or corporation has
or will have, as a result of any act or omission of the Company, any right,
interest or valid claim against or upon the Company or any Purchaser for any
commission, fee or other compensation as a finder or broker, or in any similar
capacity, in connection with the transactions contemplated by this Agreement.
The Company will defend and indemnify and hold each Purchaser harmless against
any and all liability with respect to any such commission, fee or other
compensation which may be payable or determined to be payable in connection with
the transactions contemplated by this Agreement.

          13.14     REGISTRATION RIGHTS.  Other than under this Agreement, 
the Company has not agreed to register any of its authorized or outstanding 
securities under the Securities Act.

          13.15     REGISTRATION STATEMENT.  To the knowledge of the Company,

preparation and filing of a registration statement on Form S-3 with respect 
to the Preferred Shares, the Conversion Stock and the Warrant Stock.

contemplated by this Agreement, satisfies all applicable requirements of 
NASDAQ for such listing, including, without limitation, all applicable

reports, statements (including proxy statements) and schedules with the 
Commission required to be filed pursuant to the Securities and Exchange Act 
of 1934 (the "Exchange Act") or other federal securities laws (the "SEC 
Reports"). The SEC Reports complied in all material respects with all 
applicable requirements of the Exchange Act or other federal securities laws 
and did not (as of their respective filing dates) contain any untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary in order to make the statements made therein, in 
light of the circumstances under which they were made, not misleading.  The 
audited and unaudited consolidated financial statements of the Company 
included (or incorporated by reference) in the SEC Reports have been prepared 
in accordance with generally accepted accounting principles applied on a 
consistent basis and fairly present the financial position of the Company as 
of the dates thereof and the results of its operations and changes in 
financial position for the periods then ended, subject, in the case of the 
unaudited financial statements, to normal year-end audit adjustments.  The 
Company has registration statements on file with the Commission which are set 
forth on Schedule 5.17.

          13.18     DISCLOSURE.  The Company has not knowingly withheld from 
the Purchasers any material facts relating to the assets, business, 
operations, financial condition or prospects of the Company.  No 
representation or warranty in this Agreement or in any certificate, schedule, 
statement or other document furnished or to be furnished to the Purchasers 
pursuant hereto or in connection with the transactions contemplated hereby, 
contains or will contain any untrue statement of a material fact or omits or 
will omit to state any material fact required to be stated herein or therein 
or necessary to make the statements herein or therein not misleading.

the Certificate of Designation which shall be filed and effective prior to 
the Closing.

          13.20     ANTI-DILUTION SHARES.  The issuance of the Preferred 
Shares, the Conversion Stock, the Warrants and the Warrant Stock will not 
result in the issuance of any additional shares of the capital stock of the 
Company or any triggering of any other rights of first refusal or 
anti-dilution, preemptive or similar rights contained in any options, 
warrants,  debentures, other securities or agreements or commitments of the 
Company.  All rights of first refusal, anti-dilution or similar rights with 
respect to the issuance of the Preferred Shares, the Warrants, the Conversion 
Stock and the Warrant Stock have been validly waived.

     14.  REPRESENTATIONS AND WARRANTIES OF PURCHASERS.  Each of the 
Purchasers represents and warrants for itself that:

          14.1      INVESTMENT INTENT.    The Preferred Shares being acquired 
by each Purchaser hereunder are being purchased, and the Conversion Stock and 
the Warrant Stock acquired by each Purchaser upon conversion of such 
Preferred Shares or exercise of the Warrants will be acquired, for such 
Purchaser's own account and not with the view to, or for resale in connection 
with, any distribution or public offering thereof within the meaning of the 
Securities Act, except pursuant to sales that are exempt from the 
registration requirements of the Securities Act and/or pursuant to 
registration as contemplated by Section 11 of this Agreement.  Such Purchaser 
understands that the Preferred Shares and the Conversion Stock, and the 
Warrants and the Warrant Stock, have not been registered under the Securities 
Act or any applicable state laws by reason of their issuance or contemplated 
issuance in a transaction exempt from the registration and prospectus 
delivery requirements of the Securities Act and such laws, and that the 
reliance of the Company upon this exemption is predicated in part upon this 
representation and warranty.  Such Purchaser further understands that the 
Preferred Shares and Conversion Stock, and the Warrants and the Warrant 
Stock, may not be transferred or resold without (a) registration under the 
Securities Act and any applicable state securities laws, or (b) an exemption 
from the requirements of the Securities Act and applicable state securities 
laws.

          Such Purchaser understands that an exemption from such registration 
is not presently available pursuant to Rule 144 promulgated under the 
Securities Act, and that in any event such Purchaser may not sell any 
securities pursuant to Rule 144 prior to the expiration of a one-year period 
after such Purchaser has acquired the securities.

          14.2      LOCATION OF PRINCIPAL OFFICE AND ACCESS TO COMPANY RECORDS.
The state in which each Purchaser's principal office is located is set forth in
Section 14 of this 

                               Page 28 of 87 Pages
<PAGE>

Agreement.  Such Purchaser has been provided with documents requested by it, 
and access to the Company's executive officers has been provided to such 
Purchaser or to such Purchaser's qualified agents.

          14.3      ACTS AND PROCEEDINGS.  This Agreement has been duly 
authorized by all necessary action on the part of such Purchaser, has been 
duly executed and delivered by such Purchaser, and is a valid and binding 
agreement upon the part of such Purchaser.

          14.4      NO BROKERS OR FINDERS.  No person, firm or corporation

The Company shall file prior to the Closing with the Minnesota Secretary of

     17.  THE PREFERRED SHARES.

          17.1      CONVERSION OF PREFERRED SHARES.  Any holder of Preferred 
Shares may, at its option, at any time and from time to time, convert such 
Preferred Shares, or any thereof,  into Conversion Stock at the rate and upon

Certificate of Designation.

          17.2      STOCK FULLY PAID: RESERVATION OF SHARES.  The Company 
covenants and agrees that all Conversion Stock that may be issued upon 
conversion of the Preferred Shares will, upon issuance in accordance with the 
terms of the Certificate of Designation, be fully paid and nonassessable, and 
that the issuance thereof shall not give rise to any preemptive rights on the 
part of any person.  The Company further covenants and agrees that the 
Company will at all times have authorized and reserved a sufficient number of 
shares of its Common Stock for the purpose of issue upon the conversion of 
the Preferred Shares.

     18.  THE WARRANTS.

          18.1      EXERCISE OF WARRANTS.  For a period of two (2) years from 
the Closing Date, any holder of any Warrants may, at its option, at any time 
and from time to time, exercise such Warrants, or any portion thereof, upon

Warrants.

          18.2      STOCK FULLY PAID; RESERVATION OF SHARES.  The Company 
covenants and agrees that all Warrant Stock that may be issued upon the 
exercise of the Warrants will, upon issuance in accordance with the terms of

shall not give rise to any preemptive rights on the part of any person.

     19.  REGISTRATION OF STOCK.

          19.1      REQUIRED REGISTRATION.  Within 30 days of the Closing, the
Company shall prepare and file one registration statement under the Securities
Act (the "Resale Registration Statement") covering all of the shares of
Conversion Stock and Warrant Stock (collectively, the "Registrable Securities")
and shall use its best efforts (i) to cause such 

                               Page 34 of 87 Pages
<PAGE>

Resale Registration Statement to be declared effective by the Commission for 
such Registrable Securities as soon as practicable thereafter and (ii) to 
keep the Resale Registration Statement continuously effective until the 
earliest of (x) the date on which the Purchasers no longer hold or have the 
right to acquire any Registrable Securities or (y) the third anniversary of 
the effective date of the Resale Registration Statement, or such earlier date 
at which Rule 144(k) under the Securities Act (or any successor rule thereto) 
enables each holder of Registrable Securities to sell all of its Registrable 
Securities without restriction under the Securities Act.

          19.2      INCIDENTAL REGISTRATION.  Each time the Company shall 
determine to proceed with the actual preparation and filing of a registration 
statement under the Securities Act in connection with the proposed offer and 
sale for cash of any of its securities by it or any of its security holders 
(other than a registration statement on a form that does not permit the 
inclusion of shares by its security holders), the Company will promptly give 
written notice of its determination to all record holders of Purchased Stock 
(as hereinafter defined). Upon the written request of a record holder of any 
shares of Purchased Stock given within 30 days after receipt of any such 
notice from the Company, the Company will, except as herein provided, cause 
all the shares of Conversion Stock and Warrant Stock, the Purchasers or 
record holders of which have so requested registration thereof, to be 
included in such registration statement, all to the extent requisite to 
permit the sale or other disposition by the prospective seller or sellers of 
the Conversion Stock or Warrant Stock to be so registered; provided, however, 
that nothing herein shall prevent the Company from, at any time, abandoning 
or delaying any such registration initiated by it; provided further, however, 
that if the Company determines not to proceed with a registration after the 
registration statement has been filed with the Commission and the Company's 
decision not to proceed is primarily based upon the anticipated public 
offering price of the securities to be sold by the Company, the Company shall 
promptly complete the registration for the benefit of those selling security 
holders who wish to proceed with a public offering of their securities at the 
Company's expense.  If any registration pursuant to this Section 11.2 shall 
be underwritten in whole or in part, the Company may require that the 
Conversion Stock or Warrant Stock requested for inclusion pursuant to this 
Section 11.2 be included in the underwriting on the same terms and conditions 
as the securities otherwise being sold through the underwriters. In the event 
that the Conversion Stock or Warrant Stock requested for inclusion pursuant 
to this Section 11.2 would constitute more than 25 % of the total number of 
shares to be included in a proposed underwritten public offering, and if in 
the good faith judgment of the managing underwriter of such public offering 
the inclusion of all of the Conversion Stock or Warrant Stock originally 
covered by a request for registration would reduce the number of shares to be 
offered by the Company or interfere with the successful marketing of the 
shares of stock offered by the Company, the number of shares of Conversion 
Stock and Warrant Stock otherwise to be included in the underwritten public 
offering may be reduced pro rata (by number of shares) among the holders 
thereof requesting such registration, provided, however, that after any such 
required reduction the Conversion Stock and Warrant Stock to 

                               Page 35 of 87 Pages
<PAGE>

be included in such offering shall constitute at least 25% of the total 
number of shares to be included in such offering.  "Purchased Stock" shall 
mean the Preferred Shares, the Conversion Stock, the Warrants, the Warrant 
Stock, and the stock or other securities of the Company issued in a stock 
split or reclassification of, or a stock dividend or other distribution on or 
in substitution or exchange for, or otherwise in connection with, any of the 
foregoing securities, or in a merger or consolidation involving the Company 
or a sale of all or substantially all of the Company's assets.

          19.3      REGISTRATION PROCEDURES.  If and whenever the Company is 
required by the provisions of Section 11.1 or 11.2 hereof to effect the 
registration of Registrable Securities under the Securities Act, the Company 
will:

          (a)  prepare and file with the Commission a registration statement 
     (a "Registration Statement") with respect to such Registrable 
     Securities, and use its best efforts to cause such Registration 
     Statement to become and remain effective for such period as may be 
     reasonably necessary to effect the sale of such securities, not to 
     exceed three years in the case of a registration pursuant to Section 
     11.1 and nine months in the case of a registration pursuant to Section 
     11.2 (subject to extension as set forth in the last paragraph of this 
     Section 11.3);

          (b)  prepare and file with the Commission such amendments to such 
     Registration Statement and supplements to such Registration Statement 
     and the Prospectus contained therein (a "Prospectus") as may be 
     necessary to keep such Registration Statement effective for such period 
     as may be reasonably necessary to effect the sale of such securities, 
     not to exceed three years in the case of a registration pursuant to 
     Section 11.1 and nine months in the case of a registration pursuant to 
     Section 11.2, and to comply with the provision of the Securities Act 
     (subject to extension as set forth in the last paragraph of this Section 
     11.3);

          (c)  use its best efforts to register and qualify the securities 
     covered by such Registration Statement under such state securities or 
     blue sky laws of such jurisdictions as such participating holders may 
     reasonably request in writing within 20 days following the original 
     filing of such Registration Statement, except that the Company shall not 
     for any purpose be required to qualify to do business as a foreign 
     corporation in any jurisdiction wherein it is not so qualified;

          (d)  notify the security holders participating in such
     registration, promptly after it shall receive notice thereof, of the
     time when such 

                               Page 36 of 87 Pages
<PAGE>

     Registration Statement has become effective or a supplement to any 
     Prospectus forming a part of such Registration Statement has been filed;

          (e)  notify such holders promptly of any request by the Commission 
     for the amending or supplementing of such Registration Statement or 
     Prospectus or for additional information;

          (f)  prepare and promptly file with the Commission and promptly 
     notify such holders of the filing of such amendment or supplement to 
     such Registration Statement or Prospectus as may be necessary to correct 
     any statements or omissions if, at the time when a Prospectus relating 
     to such securities is required to be delivered under the Securities Act, 
     any event shall have occurred as the result of which any such Prospectus 
     or any other prospectus as then in effect would include an untrue 
     statement of a material fact or omit to state any material fact 
     necessary to make the statements therein, in the light of the 
     circumstances in which they were made, not misleading;

          (g)  advise such holders, promptly after it shall receive notice or 
     obtain knowledge thereof, of the issuance of any stop order by the 
     Commission suspending the effectiveness of such registration statement 
     or the initiation or threatening of any proceeding for that purpose and 
     promptly use its best efforts to prevent the issuance of any stop order 
     or to obtain its withdrawal if such stop order should be issued;

          (h)  advise such holders (i) when a Prospectus or any Prospectus 
     supplement or post-effective amendment has been filed and, with respect 
     to a Registration Statement or any post-effective amendment, when the 
     same has become effective, (ii) of any request by the Commission or any 
     state securities authority for amendments and supplements to a 
     Registration Statement and Prospectus or for additional information 
     after the Registration Statement has become effective, (iii) of the 
     issuance by the Commission of any stop order suspending the 
     effectiveness of a Registration Statement, (iv) of the issuance by any 
     state securities commission or other regulatory authority of any order 
     suspending the qualification or exemption from qualification of any of 
     the Registrable Securities under state securities or "blue sky" laws, 
     and (v) of the happening of any event which makes any statement made in 
     a Registration Statement or related Prospectus untrue or which requires 
     the making of any changes in such Registration Statement or Prospectus 
     so that they will not contain any untrue statement of a material fact or 
     omit to state any material fact required to be stated therein or 
     necessary to make the statements therein, in light of the circumstances 
     under which they were made, not misleading.  As soon as practicable 
     following expiration of the Suspension Period (as defined 

                               Page 37 of 87 Pages
<PAGE>

     below), the Company shall prepare and file with the Commission and 
     furnish a supplement or amendment to such Prospectus so that, as 
     thereafter deliverable to the purchasers of such Registrable Securities, 
     such Prospectus will not contain any untrue statement of a material fact 
     or omit to state a material fact necessary to make the statements 
     therein, in light of the circumstances under which they were made, not 
     misleading;

          (i)  furnish to such holders such number of copies of a Prospectus, 
     including a preliminary Prospectus, in conformity with the requirements 
     of the Securities Act, and such other documents, as they may reasonably 
     request in order to facilitate the disposition of the Registrable 
     Securities owned by them that are included in such registration;

          (j)  in the event of any underwritten public offering, enter into 
     and perform its obligations under an underwriting agreement, in usual 
     and customary form, with the managing underwriter(s) of such offering; 
     and

          (k)  use its best efforts to secure the listing of the Registrable 
     Securities covered by a registration statement on the NASDAQ SmallCap 
     Market (or the principal exchange, market or system on which the 
     Company's Common Stock shall then be listed or traded).

          Upon receipt of any notice (a "Suspension Notice") by a holder from 
the Company of the happening of any event of the kind described in Section 
11.3(h)(ii), (iii) or (v), a holder shall forthwith discontinue disposition 
of the Registrable Securities pursuant to the Registration Statement covering 
such Registrable Securities until receipt of the copies of the supplemented 
or amended Prospectus contemplated by Section 11.3(h) or until the holder is 
advised in writing (the "Advice") by the Company that the use of the 
Prospectus may be resumed, and has received copies of any additional or 
supplemental filings which are incorporated by reference in the Prospectus, 
and, if so directed by the Company, will, or will request any broker-dealer 
acting as holder's agent to, deliver to the Company (at the Company expense) 
all copies, other than permanent file copies then in the holder's or 
broker-dealer's possession, of the Prospectus covering such Registrable 
Securities current at the time of receipt of such notice; PROVIDED, HOWEVER, 
that in no event shall the period from the date on which the holder receives 
a Suspension Notice to the date on which the holder receives either the 
Advice or copies of the supplemented or amended Prospectus contemplated by 
Section 11.3(h), and any additional or supplemental filings incorporated 
therein by reference (the "Suspension Period"), exceed 60 days.  The period 
during which the Company is required under this Agreement to keep any 
Registration Statement filed pursuant to Section 11.1 or 11.2 effective shall 
be extended by the number of days during a period that the Registration 
Statement required to be filed under Section 11.1 of the 

                               Page 38 of 87 Pages
<PAGE>

Agreement is subject to a stop order or is otherwise not in effect or the 
holder is advised that the prospectus included therein contains a material 
misstatement or omission.

          19.4      EXPENSES.  Except as provided in this Section 11.4, with 
respect to the registration pursuant to Section 11.1 hereof and with respect 
to each inclusion of shares of Conversion Stock and Warrant Stock in a 
Registration Statement pursuant to Section 11.2 hereof, the Company shall 
bear all fees, costs and expenses except expenses of counsel and accountants 
for the selling securities holders.

          19.5      INDEMNIFICATION.  In the event that any Conversion Stock 
or Warrant Stock is included in a Registration Statement under Section 11.1 
or 11.2 hereof:

          (a)  The Company will indemnify and hold harmless each holder of 
     Registrable Securities which are included in a Registration Statement 
     pursuant to the provisions of this Section 11, its directors, officers, 
     partners and affiliates, and any underwriter (as defined in the 
     Securities Act) for such holder and each person, if any, who controls 
     such holder or such underwriter within the meaning of the Securities 
     Act, from and against, and will reimburse such holder, director, 
     officer, partner and affiliate and each such underwriter and controlling 
     person with respect to, any and all loss, damage, liability, cost and 
     expense (including reasonable attorneys' fees) to which such holder, 
     director, officer, partner or affiliate or any such underwriter or 
     controlling person may become subject under the Securities Act or 
     otherwise, insofar as such losses, damages, liabilities, costs or 
     expenses (including reasonable attorneys' fees) are caused by any untrue 
     statement or alleged untrue statement of any material fact contained in 
     such Registration Statement, any Prospectus contained therein or any 
     amendment or supplement thereto, or arise out of or are based upon the 
     omission or alleged omission to state therein a material fact required 
     to be stated therein or necessary to make the statements therein, in 
     light of the circumstances in which they were made, not misleading; 
     provided, however, that the Company will not be liable in any such case 
     to the extent that any such loss, damage, liability, cost or expense 
     arises out of or is based upon an untrue statement or alleged untrue 
     statement or omission or alleged omission so made in conformity with 
     information furnished by such holder, such underwriter or such 
     controlling person in writing specifically for use in the preparation 
     thereof.

          (b)  Each holder of Registrable Securities which are included in a 
     Registration Statement pursuant to the provisions of this Section 11 
     will indemnify and hold harmless the Company, its directors and 
     officers, any controlling person and any underwriter from and against, 
     and will reimburse the Company, its directors and officers, any 
     controlling person and any 

                               Page 39 of 87 Pages
<PAGE>

     underwriter with respect to, any and all loss, damage, liability, cost 
     or expense to which the Company or any controlling person and/or any 
     underwriter may become subject under the Securities Act or otherwise, 
     insofar as such losses, damages, liabilities, costs or expenses are 
     caused by any untrue or alleged untrue statement of any material fact 
     contained in such Registration Statement, any Prospectus contained 
     therein or any amendment or supplement thereto, or arise out of or are 
     based upon the omission or the alleged omission to state therein a 
     material fact required to be stated therein or necessary to make the 
     statements therein, in light of the circumstances in which they were 
     made, not misleading, in each case to the extent, but only to the 
     extent, that such untrue statement or alleged untrue statement or 
     omission or alleged omission was so made in reliance upon and in strict 
     conformity with written information furnished by such holder 
     specifically for use in the preparation thereof.

          (c)  Promptly after receipt by an indemnified party pursuant to the 
     provisions of paragraph (a) or (b) of this Section 11.5 of notice of the 
     commencement of any action involving the subject matter of the foregoing 
     indemnity provisions such indemnified party will, if a claim thereof is 
     to be made against the indemnifying party pursuant to the provisions of 
     said paragraph (a) or (b), promptly notify the indemnifying party of the 
     commencement thereof; but the omission to so notify the indemnifying 
     party will relieve such indemnifying party of liability, but only to the 
     extent that such indemnifying party is prejudiced with respect to a 
     specific claim.  In case such action is brought against any indemnified 
     party and it notifies the indemnifying party of the commencement 
     thereof, the indemnifying party shall have the right to participate in, 
     and, to the extent that it may wish, jointly with any other indemnifying 
     party similarly notified, to assume the defense thereof, with counsel 
     satisfactory to such indemnified party, provided, however, if the 
     defendants in any action include both the indemnified party and the 
     indemnifying party and the indemnified party shall have reasonably 
     concluded that there may be legal defenses available to it and/or other 
     indemnified parties which are different from or additional to those 
     available to the indemnifying party, or if there is a conflict of 
     interest which would prevent counsel for the indemnifying party from 
     also representing the indemnified party, the indemnified party or 
     parties shall have the right to select separate counsel to participate 
     in the defense of such action on behalf of such indemnified party or 
     parties.  After notice from the indemnifying party to such indemnified 
     party of its election so to assume the defense thereof, the indemnifying 
     party will not be liable to such indemnified party pursuant to the 
     provisions of said paragraph (a) or (b) for any legal or other expense 
     subsequently incurred by such indemnified party in connection with the 
     defense thereof other than reasonable costs of investigation, unless (i) 
     the

                               Page 40 of 87 Pages
<PAGE>

     indemnified party shall have employed counsel in accordance with the 
     proviso of the preceding sentence, (ii) the indemnifying party shall not 
     have employed counsel satisfactory to the indemnified party to represent 
     the indemnified party within a reasonable time after the notice of the 
     commencement of the action, or (iii) the indemnifying party has 
     authorized the employment of counsel for the indemnified party at the 
     expense of the indemnifying party.

          (d)  If the indemnification provided for in paragraph (a) or (b) of 
     this Section 11.5 shall be unavailable to hold harmless an indemnified 
     party in respect of any loss, damage, liability, cost or expenses 
     (including reasonable attorneys' fees) under the Securities Act or 
     otherwise, then, and in each such case, the indemnifying party, in lieu 
     of indemnifying such indemnified party hereunder, shall contribute to 
     the amount paid or payable by such indemnified party as a result of such 
     loss, damage, liability, cost or expense in such proportion as is 
     appropriate to reflect the relative fault of the indemnifying party on 
     the one hand and of the indemnified party on the other in connection 
     with the statement or omissions that resulted in such loss, damage, 
     liability, cost or expenses (including reasonable attorneys' fees) as 
     well as any other relevant equitable considerations.  The relative fault 
     of the indemnifying party and of the indemnified party shall be 
     determined by reference to, among other things, whether the untrue or 
     alleged untrue statement of a material fact or the omission to state a 
     material fact relates to information supplied by the indemnifying party 
     or by the indemnified party and the parties' relative intent, knowledge, 
     access to information and opportunity to correct or prevent such 
     statement or omission; PROVIDED that in no event shall any contribution 
     under this subsection (d) by any holder exceed the gross proceeds from 
     the offering received by such indemnifying party.  No person or entity 
     guilty of fraudulent misrepresentation (within the meaning of Section 
     11(f) of the Securities Act) will be entitled to contribution from any 
     person or entity who was not guilty of such fraudulent misrepresentation.

          (e)  The obligations of the Company and the holders under this 
     Section 11.5 will survive the completion of any offering of Registrable 
     Securities in a Registration Statement, and otherwise.

     20.  GENERAL INDEMNITY.  The Company will indemnify and hold harmless the
Purchasers, and their respective officers, directors, general partners,
employees, agents and affiliates, from and against any and all claims,
liabilities, losses, damages and expenses (including reasonable attorneys' fees)
incurred by any of such indemnified parties in any way relating to, arising out
of or resulting from (i) the breach of any of the representations or warranties
made by the Company in this Agreement and (ii) the breach or the failure of

                               Page 41 of 87 Pages

                            CERTIFICATE OF DESIGNATION
                    OF SERIES III CONVERTIBLE PREFERRED STOCK

     I, the undersigned, as President and Chief Executive Officer of 
Telident, Inc., a Minnesota corporation (the "Corporation"), do hereby 
certify that the Board of Directors of the Corporation unanimously resolved, 
on April 8, 1998, to establish a class of Preferred Stock as permitted in 
Article III of the Corporation's Articles of Incorporation, as amended, in 
accordance with the following resolutions:
     RESOLVED, that the officers of the Corporation be, and they hereby are, 
     authorized and directed to issue 400,000 shares of the Corporation's 
     Preferred Stock and Warrants to purchase 400,000 shares of Common Stock 
     of the Corporation to the Purchasers identified in that certain Stock 
     Purchase Agreement dated April 13, 1998 by and among the Corporation and 
     the Purchasers named therein (the "Stock Purchase Agreement"), in 
     consideration for which the Purchasers shall pay the Corporation 
     $1,000,000.00, such amount to be paid by wire transfer concurrently with 
     the issuance of the Corporation's stock certificates representing said 
     shares and the warrants.

     FURTHER RESOLVED, that such shares of Preferred Stock shall be referred 
     to and designated as the Series III Convertible Preferred Stock of the 
     Corporation (the "Series III Preferred Stock") and shall have the 
     following relative rights and preferences:
                                       
                                   ARTICLE 31.

     TERMS OF THE SERIES III CONVERTIBLE PREFERRED STOCK:

     1.   VOTING PRIVILEGES.

     a.   GENERAL.  Each holder of Series III Preferred Stock shall have that 
number of votes on all matters submitted to the stockholders that is equal to 
the number of shares of Common Stock into which such holder's shares of 
Series III Preferred Stock are then convertible, as hereinafter provided.  
Except as provided herein or as otherwise required by agreement or law, all 
shares of capital stock of the Corporation shall vote as a single class on 
all matters submitted to the stockholders.

     b.   NO CUMULATIVE VOTING.  No holder of shares of Series III Preferred 
Stock of the Corporation shall have any cumulative voting rights.

                               Page 52 of 87 Pages
<PAGE>

     c.   MERGERS, CONSOLIDATIONS AND DISPOSITIONS OF ASSETS.  Without the 
affirmative vote or written consent of the holders (acting together as a 
class) of 66.67% of the shares of Series III Preferred Stock at the time 
outstanding, the Corporation shall not enter into any agreement or 
understanding to (i) merge or consolidate the Corporation into or with 
another corporation, (ii) merge or consolidate any other corporation into or 
with the Corporation, (iii) effectuate a plan of exchange between the 
Corporation and any other corporation, (iv) sell, transfer or dispose of all 
or substantially all of the assets of the Corporation; (v) amend this 
Certificate of Designation; or (vi) issue any shares of the Corporation's 
capital stock which have rights and preferences greater than those of the 
Series III Preferred Stock.

     2.   DIVIDENDS.

     In the event any dividend or distribution is declared or made with 
respect to outstanding shares of Common Stock or series I convertible 
preferred stock, a comparable dividend or distribution must be simultaneously 
declared or made with respect to the outstanding shares of Series III 
Preferred Stock.  In the event any dividend or distribution is declared or 
made with respect to the Common Stock or the series I convertible stock, each 
holder of shares of Series III Preferred Stock shall be paid such comparable 
dividend or receive such comparable distribution on the basis of the number 
of shares of Common Stock into which such holder's shares of such Series III 
Preferred Stock are then convertible, as hereinafter provided.

     Dividends on shares of capital stock of the Corporation shall be payable 
only out of funds legally available therefor.

     3.   OTHER TERMS OF THE SERIES III PREFERRED STOCK.

     a.   LIQUIDATION PREFERENCE.  In the event of an involuntary or 
voluntary liquidation or dissolution of the Corporation at any time, the 
holders of shares of Series III Preferred Stock shall be entitled to receive 
out of the assets of the Corporation an amount equal to the Per Share 
Purchase Price (appropriately adjusted to reflect stock splits, stock 
dividends, reorganizations, consolidations and similar changes hereafter 
effected), plus dividends unpaid and accumulated or accrued thereon.  In the 
event of either an involuntary or a voluntary liquidation or dissolution of 
the Corporation payment shall be made to the holders of shares of Series III 
Preferred Stock in the amounts herein fixed pari passu with series I 
convertible preferred stock and before any payment shall be made or any 
assets distributed to the holders of the Common Stock or any other class of 
shares of the Corporation ranking junior to the Series III Preferred Stock 
with respect to payment upon dissolution or liquidation of the Corporation.  
If upon any liquidation or dissolution of the Corporation the assets 
available for distribution shall be insufficient to pay the holders of all 
outstanding shares of Series III Preferred Stock the full amounts to which 
they respectively shall be 

                               Page 53 of 87 Pages
<PAGE>

entitled, the holders of such shares shall share pro rata in any such 
distribution in proportion to the full amounts to which such holders would 
otherwise be entitled.

     Nothing hereinabove set forth shall affect in any way the right of each 
holder of shares of Series III Preferred Stock to convert such shares at any 
time and from time to time in accordance with subparagraph (2) below.

     b.   CONVERSION RIGHT.  At the option of the holders thereof, all or any 
portion of the shares of Series III Preferred Stock shall be convertible, at 
the office of the Corporation (or at such other office or offices, if any, as 
the Board of Directors may designate).  Upon any such conversion, each share 
of Series III Preferred Stock which a holder elects to convert shall be 
converted into a number of fully paid and nonassessable shares (calculated as 
to each conversion to the nearest 1/100th of a share) of Common Stock of the 
Corporation equal to the quotient of (x) the Per Share Purchase Price 
(appropriately adjusted to reflect stock splits, stock dividends, 
reorganizations, consolidations and similar changes hereafter effected) of 
such share of Series III Preferred Stock, divided by (y) the lesser of (i) 
the Conversion Price (as hereinafter defined) or (ii) if the average of the 
closing bid price for the shares of Common Stock (appropriately adjusted to 
reflect stock splits, stock dividends, reorganizations, consolidations and 
similar changes hereafter effected) on the ten (10) trading days prior to the 
date that the Corporation receives written notice of conversion from such 
holder of such Series III Preferred Stock (the"Average Price") is less than 
the Per Share Purchase Price (appropriately adjusted to reflect stock splits, 
stock dividends, reorganizations, consolidations and similar changes 
hereafter effected), then 80% of such Average Price.  The initial Conversion 
Price shall be the Per Share Purchase Price; such Conversion Price shall be 
subject to adjustment from time to time in certain instances as hereinafter 
provided.  The following provisions shall govern such right of conversion:

     a.   In order to convert shares of Series III Preferred Stock into 
          shares of Common Stock of the Corporation, the holder thereof shall 
          surrender at any office hereinabove mentioned the certificate or 
          certificates therefor, duly endorsed to the Corporation or in 
          blank, and give written notice to the Corporation at such office 
          that such holder elects to convert such shares.  Shares of Series 
          III Preferred Stock shall be deemed to have been converted 
          immediately prior to the close of business on the day of the 
          surrender of such shares for conversion as herein provided, and the 
          person entitled to receive the shares of Common Stock of the 
          Corporation issuable upon such conversion shall be treated for all 
          purposes as the record holder of such shares of Common Stock at 
          such time.  Within two (2) business days after delivery of a 
          conversion notice, the Corporation shall issue and deliver or cause 
          to be issued and delivered to the holder a certificate or 
          certificates for the number of shares of Common Stock of the 
          Corporation issuable upon such conversion.  If the holder shall 
          elect to convert only a portion of the shares of Series III 
          Preferred Stock, the 

                               Page 54 of 87 Pages
<PAGE>

          Corporation shall deliver, within two (2) business days of the 
          conversion notice, a new stock certificate representing the balance 
          of the shares represented by the surrendered certificate which 
          shall not have been converted.

     b.   Except for (i) options to purchase shares of Common Stock pursuant 
          to the Corporation's 1988 Stock Option Plan adopted by the 
          Corporation which are outstanding as of the date hereof and except 
          for shares of Common Stock issued upon the exercise of such options 
          granted pursuant to such plan and (ii) shares of Common Stock 
          issued upon conversion of the Series III Preferred Stock or 
          exercise of the Warrants issued to the holders of the Series III 
          Preferred Stock pursuant to the Stock Purchase Agreement or other 
          warrants, or rights to purchase or convert into securities of the 
          Corporation, outstanding as of the date hereof, if and whenever the 
          Corporation shall issue or sell any additional shares of its Common 
          Stock for a consideration per share less than the Conversion Price 
          in effect immediately prior to the time of such issue or sale, 
          then, forthwith upon such issue or sale, the Conversion Price shall 
          be reduced to such lesser price as is determined by multiplying the 
          Conversion Price in effect immediately prior thereto by a fraction, 
          the numerator of which shall be the sum of the number of shares of 
          Common Stock outstanding immediately prior to the issuance or sale 
          of such additional shares and the number of shares of Common Stock 
          which the aggregate consideration received (determined in 
          accordance with this paragraph 2) for the issuance or sale of such 
          additional shares would purchase at the Conversion Price then in 
          effect, and the denominator of which shall be the number of shares 
          of Common Stock outstanding immediately after the issuance or sale 
          of such additional shares.

               For the purposes of this subparagraph (b), the following 
          provisions (1) to (3), inclusive, shall also be applicable:

          (1)  In case at any time the Corporation shall grant (whether 
               directly or by assumption in a merger or otherwise) any rights 
               to subscribe for or to purchase, or any options for the 
               purchase of, (a) Common Stock or (b) any obligations or any 
               shares of stock of the Corporation which are convertible into, 
               or exchangeable for, Common Stock (any of such obligations or 
               shares of stock being hereinafter called "Convertible 
               Securities") whether or not such rights or options or the 
               right to convert or exchange any such Convertible Securities 
               are immediately exercisable, and the price per share for which 
               Common Stock is issuable upon the exercise of such rights or 
               options or upon conversion or exchange of such Convertible 
               Securities (determined by dividing (x) the total amount, if 
               any, received or receivable by the Corporation as

                               Page 55 of 87 Pages

               consideration for the granting of such rights or options, plus 
               the minimum aggregate amount of additional consideration 
               payable to the Corporation upon the exercise of such rights or 
               options, plus, in the case of such rights or options which 
               relate to Convertible Securities, the minimum aggregate amount 
               of additional consideration, if any, payable upon the issue of 
               such Convertible Securities and upon the conversion or 
               exchange thereof, by (y) the total maximum number of shares of 
               Common Stock issuable upon the exercise of such rights or 
               options or upon the conversion or exchange of all such 
               Convertible Securities issuable upon the exercise of such 
               rights or options) shall be less than the Conversion Price in 
               effect immediately prior to the time of the granting of such 
               rights or options, then the total maximum number of shares of 
               Common Stock issuable upon the exercise of such rights or 
               options or upon conversion or exchange of the total maximum 
               amount of such Convertible Securities issuable upon the 
               exercise of such rights or options shall (as of the date of 
               granting of such rights or options) be deemed to be 
               outstanding and to have been issued for such price per share.  
               No further adjustments of the Conversion Price shall be made 
               upon the actual issue of such Common Stock or of such 
               Convertible Securities upon exercise of such rights or options 
               or upon the actual issue of such Common Stock upon conversion 
               or exchange of such Convertible Securities.

          (2)  In case the Corporation shall issue or sell (whether directly 
               or by assumption in a merger or otherwise) any Convertible 
               Securities, whether or not the rights to exchange or convert 
               thereunder are immediately exercisable, and the price per 
               share for which Common Stock is issuable upon such conversion 
               or exchange (determined by dividing (x) the total amount 
               received or receivable by the Corporation as consideration for 
               the issue or sale of such Convertible Securities, plus the 
               minimum aggregate amount of additional consideration, if any, 
               payable to the Corporation upon the conversion or exchange 
               thereof, by (y) the total maximum number of shares of Common 
               Stock issuable upon the conversion or exchange of all such 
               Convertible Securities) shall be less than the Conversion 
               Price in effect immediately prior to the time of such issue or 
               sale, then the total maximum number of shares of Common Stock 
               issuable upon conversion or exchange of all such Convertible 
               Securities shall (as of the date of the issue or sale of such 
               Convertible Securities) be deemed to be outstanding and to 
               have been issued for such price per share, provided that if 
               any such issue or sale of such Convertible Securities is made 
               upon exercise of any rights to subscribe for or to purchase or 
               any option to purchase any such 

                               Page 56 of 87 Pages
<PAGE>


               Convertible Securities for which adjustments of the Conversion 
               Price have been or are to be made pursuant to other provisions 
               of this subparagraph (b), no further adjustment of the 
               Conversion Price shall be made by reason of such issue or sale.

          (3)  In case any shares of Common Stock or Convertible Securities 
               or any rights or options to purchase any such Common Stock or 
               Convertible Securities shall be issued or sold for cash, the 
               consideration received therefor shall be deemed to be the 
               amount received by the Corporation therefor, without deducting 
               therefrom any expenses incurred or any underwriting 
               commissions, discounts or concessions paid or allowed by the 
               Corporation in connection therewith.  In case any shares of 
               Common Stock or Convertible Securities or any rights or 
               options to purchase any such Common Stock or Convertible 
               Securities shall be issued or sold for a consideration other 
               than cash, the amount of the consideration other than cash 
               received by the Corporation shall be deemed to be the fair 
               value of such consideration as determined by the Board of 
               Directors of the Corporation, without deducting therefrom any 
               expenses incurred or any underwriting commissions, discounts 
               or concessions paid or allowed by the Corporation in 
               connection therewith.  In case any shares of Common Stock or 
               Convertible Securities or any rights or options to purchase 
               such Common Stock or Convertible Securities shall be issued in 
               connection with any merger or consolidation in which the 
               Corporation is the surviving corporation, the amount of 
               consideration therefor shall be deemed to be the fair value as 
               determined by the Board of Directors of the Corporation of 
               such portion of the assets and business of the non-surviving 
               corporation or corporations as such Board shall determine to 
               be attributable to such Common Stock, Convertible Securities, 
               rights or options, as the case may be.  In the event of any 
               consolidation or merger of the Corporation in which the 
               Corporation is not the surviving corporation or in the event 
               of any sale of all or substantially all of the assets of the 
               Corporation for stock or other securities of any other 
               corporation, the Corporation shall be deemed to have issued a 
               number of shares of its Common Stock for stock or securities 
               of the other corporation computed on the basis of the actual 
               exchange ratio on which the transaction was predicated and for 
               a consideration equal to the fair market value on the date of 
               such transaction of such stock or securities of the other 
               corporation, and if any such calculation results in adjustment 
               of the Conversion Price, the determination of the number of 
               shares of Common Stock issuable upon conversion immediately 
               prior to such merger, conversion or sale, for 

                               Page 57 of 87 Pages

               purposes of subparagraph (f) below, shall be made after giving 
               effect to such adjustment of the Conversion Price.

     c.   In case the Corporation shall (i) declare a dividend upon the 
          Common Stock payable in Common Stock (other than a dividend 
          declared to effect a subdivision of the outstanding shares of 
          Common Stock, as described in subparagraph (d) below) or 
          Convertible Securities, or in any rights or options to purchase 
          Common Stock or Convertible Securities, or (ii) declare any other 
          dividend or make any other distribution upon the Common Stock 
          payable otherwise than out of earnings or earned surplus, then 
          thereafter each holder of shares of Series III Preferred Stock upon 
          the conversion thereof will be entitled to receive the number of 
          shares of Common Stock into which such shares of Series III 
          Preferred Stock have been converted, and, in addition and without 
          payment therefor, each dividend described in clause (i) above and 
          each dividend or distribution described in clause (ii) above which 
          such holder would have received by way of dividends or 
          distributions if continuously since the issuance of such shares of 
          Series III Preferred Stock, such holder (i) had been the record 
          holder of the number of shares of Common Stock then received, and 
          (ii) had retained all dividends or distributions in stock or 
          securities (including Common Stock or Convertible Securities, or in 
          any rights or options to purchase any Common Stock or Convertible 
          Securities) payable in respect of such Common Stock or in respect 
          of any stock or securities paid as dividends or distributions and 
          originating directly or indirectly from such Common Stock.  For the 
          purposes of the foregoing a dividend or distribution other than in 
          cash shall be considered payable out of earnings or earned surplus 
          only to the extent that such earnings or earned surplus are charged 
          an amount equal to the fair value of such dividend or distribution 
          as determined by the Board of Directors of the Corporation.

     d.   In case the Corporation shall at any time subdivide its outstanding 
          shares of Common Stock into a greater number of shares, the 
          Conversion Price in effect immediately prior to such subdivision 
          shall be proportionately reduced, and conversely, in case the 
          outstanding shares of Common Stock of the Corporation shall be 
          combined into a smaller number of shares, the Conversion Price in 
          effect immediately prior to such combination shall be 
          proportionately increased.

     e.   If (i) the purchase price provided for in any right or option 
          referred to in clause (1) of subparagraph (b), or (ii) the 
          additional consideration, if any, payable upon the conversion or 
          exchange of Convertible Securities referred to in clause (1) or 
          clause (2) of subparagraph (b), or (iii) the rate at which any 
          Convertible Securities referred to in clause (1) or clause (2) of 
          subparagraph (b) are 

                               Page 58 of 87 Pages
<PAGE>

          convertible into or exchangeable for Common Stock, shall change at 
          any time (other than under or by reason of provisions designed to 
          protect against dilution), the Conversion Price then in effect 
          hereunder shall forthwith be increased or decreased to such 
          Conversion Price as would have been obtained had the adjustments 
          made upon the issuance of such rights, options or Convertible 
          Securities been made upon the basis of (a) the issuance of the 
          number of shares of Common Stock theretofore actually delivered 
          upon the exercise of such options or rights or upon the conversion 
          or exchange of such Convertible Securities, and the total 
          consideration received therefor, and (b) the issuance at the time 
          of such change of any such options, rights, or Convertible 
          Securities then still outstanding for the consideration, if any, 
          received by the Corporation therefor and to be received on the 
          basis of such changed price; and on the expiration of any such 
          option or right or the termination of any such right to convert or 
          exchange such Convertible Securities, the Conversion Price then in 
          effect hereunder shall forthwith be increased to such Conversion 
          Price as would have obtained had the adjustments made upon the 
          issuance of such rights or options or Convertible Securities been 
          made upon the basis of the issuance of the shares of Common Stock 
          theretofore actually delivered (and the total consideration 
          received therefor) upon the exercise of such rights or options or 
          upon the conversion or exchange of such Convertible Securities.  If 
          the purchase price provided for in any right or option referred to 
          in clause (1) of subparagraph (b), or the rate at which any 
          Convertible Securities referred to in clause (1) or clause (2) of 
          subparagraph (b) are convertible into or exchangeable for Common 
          Stock, shall decrease at any time under or by reason of provisions 
          with respect thereto designed to protect against dilution, then in 
          case of the delivery of Common Stock upon the exercise of any such 
          right or option or upon conversion or exchange of any such 
          Convertible Security, the Conversion Price then in effect hereunder 
          shall forthwith be decreased to such Conversion Price as would have 
          obtained had the adjustments made upon the issuance of such right, 
          option or Convertible Security been made upon the basis of the 
          issuance of (and the total consideration received for) the shares 
          of Common Stock delivered as aforesaid.

     f.   If any capital reorganization or reclassification of the capital 
          stock of the Corporation, or consolidation or merger of the 
          Corporation with another corporation, or the sale of all or 
          substantially all of its assets to another corporation shall be 
          effected in such a way that the holders of Common Stock shall be 
          entitled to receive stock, securities or assets with respect to or 
          in exchange for Common Stock, then, as a condition of such 
          reorganization, reclassification, consolidation, merger or sale, 
          lawful and adequate provision shall be made whereby the holders of 
          Series III Preferred Stock shall thereafter 

                               Page 59 of 87 Pages
<PAGE>

          have the right to receive upon the basis and upon the terms and 
          conditions specified herein and in lieu of the shares of the Common 
          Stock of the Corporation immediately theretofore receivable upon 
          the conversion of Series III Preferred Stock, such shares of stock, 
          securities or assets as may be issued or payable with respect to or 
          in exchange for a number of outstanding shares of such Common Stock 
          equal to the number of shares of such stock immediately theretofore 
          receivable upon the conversion of Series III Preferred Stock had 
          such reorganization, reclassification, consolidation, merger or 
          sale not taken place, plus all dividends unpaid and accumulated or 
          accrued thereon to the date of such reorganization, 
          reclassification, consolidation, merger or sale, and in any such 
          case appropriate provision shall be made with respect to the rights 
          and interests of the holders of Series III Preferred Stock to the 
          end that the provisions hereof (including without limitation 
          provisions for adjustments of the Conversion Price and of the 
          number of shares receivable upon the conversion of Series III 
          Preferred Stock) shall thereafter be applicable, as nearly as may 
          be in relation to any shares of stock, securities or assets 
          thereafter receivable upon the conversion of Series III Preferred 
          Stock. The Corporation shall not effect any such consolidation, 
          merger or sale, unless prior to the consummation thereof the 
          successor corporation (if other than the Corporation) resulting 
          from such consolidation or merger or the corporation purchasing 
          such assets shall assume by written instrument executed and mailed 
          to the registered holders of Series III Preferred Stock, at the 
          last addresses of such holders appearing on the books of the 
          Corporation, the obligation to deliver to such holders such shares 
          of stock, securities or assets as, in accordance with the foregoing 
          provisions, such holders may be entitled to receive.

     g.   In case at any time:

          (1)  the Corporation shall declare any cash dividend on its Common 
               Stock at a rate in excess of the rate of the last cash 
               dividend theretofore paid;

          (2)  the Corporation shall pay any dividend payable in stock upon 
               its Common Stock or make any distribution (other than regular 
               cash dividends) to the holders of its Common Stock;

          (3)  the Corporation shall offer for subscription pro rata to the 
               holders of its Common Stock any additional shares of stock of 
               any class or other rights;

          (4)  there shall be any capital reorganization, or reclassification 
               of the capital stock of the Corporation, or consolidation or 
               merger of the 

                               Page 60 of 87 Pages
<PAGE>

               Corporation with, or sale of all or substantially all of its 
               assets to, another corporation; or

          (5)  there shall be a voluntary or involuntary dissolution, 
               liquidation or winding up of the Corporation;

          then, in any one or more of said cases, the Corporation shall give 
          written notice, by first-class mail, postage prepaid, addressed to 
          the registered holders of Series III Preferred Stock at the 
          addresses of such holders as shown on the books of the Corporation, 
          of the date on which (a) the books of the Corporation shall close 
          or a record shall be taken for such dividend, distribution or 
          subscription rights, or (b) such reorganization, reclassification, 
          consolidation, merger, sale, dissolution, liquidation or winding up 
          shall take place, as the case may be.  Such notice shall also 
          specify the date as of which the holders of Common Stock of record 
          shall participate in such dividend, distribution or subscription 
          rights, or shall be entitled to exchange their Common Stock for 
          securities or other property deliverable upon such reorganization, 
          reclassification, consolidation, merger, sale, dissolution, 
          liquidation, or winding up, as the case may be.  Such written 
          notice shall be given at least 20 days prior to the action in 
          question and not less than 20 days prior to the record date or the 
          date on which the Corporation's transfer books are closed in 
          respect thereto.

     h.   If any event occurs as to which in the opinion of the Board of 
          Directors of the Corporation the other provisions of this paragraph 
          (2) are not strictly applicable or if strictly applicable would not 
          fairly protect the rights of the holders of Series III Preferred 
          Stock in accordance with the essential intent and principles of 
          such provisions, then the Board of Directors shall make an 
          adjustment in the application of such provisions, in accordance 
          with such essential intent and principles, so as to protect such 
          rights as aforesaid.

     i.   As used in this paragraph (2) the term "Common Stock" shall mean 
          and include the Corporation's presently authorized Common Stock and 
          shall also include any capital stock of any class of the 
          Corporation hereafter authorized which shall not be limited to a 
          fixed sum or percentage in respect of the rights of the holders 
          thereof to participate in dividends or in the distribution of 
          assets upon the voluntary or involuntary liquidation, dissolution 
          or winding up of the Corporation; provided that the shares 
          receivable pursuant to conversion of shares of Series III Preferred 
          Stock shall include shares designated as Common Stock of the 
          Corporation as of the date of issuance of such shares of Series III 
          Preferred Stock, or, in case of any reclassification of the 
          outstanding shares thereof, the stock, securities or assets 
          provided for in subparagraph (f) above.

                               Page 61 of 87 Pages

     j.   No fractional shares of Common Stock shall be issued upon 
          conversion, but, instead of any fraction of a share which would 
          otherwise be issuable, the Corporation shall pay a cash adjustment 
          in respect of such fraction in an amount equal to the same fraction 
          of the Market Price per share of Common Stock as of the close of 
          business on the day of conversion.  "Market Price" shall mean if 
          the Common Stock is traded on a securities exchange, The NASDAQ 
          National Market or The NASDAQ SmallCap Market, the closing price of 
          the Common Stock on such exchange, The NASDAQ National Market or 
          The NASDAQ SmallCap Market, or, if the Common Stock is otherwise 
          traded in the over-the-counter market, the closing price, in each 
          case averaged over a period of 20 consecutive business days prior 
          to the date as of which "Market Price" is being determined.  If at 
          any time the Common Stock is not traded on an exchange, The NASDAQ 
          National Market or The NASDAQ SmallCap Market, or otherwise traded 
          in the over-the-counter market, the "Market Price" shall be deemed 
          to be the higher of (i) the book value thereof as determined by any 
          firm of independent public accountants of recognized standing 
          selected by the Board of Directors of the Corporation as of the 
          last day of any month ending within 60 days preceding the date as 
          of which the determination is to be made, or (ii) the fair value 
          thereof determined in good faith by the Board of Directors of the 
          Corporation as of a date which is within 15 days of the date as of 
          which the determination is to be made.

     k.   The holders of the Series III Preferred Stock shall be entitled to 
          the registration rights provided for in Section 11 of the Stock 
          Purchase Agreement.

     l.   Whenever the Conversion Price is adjusted, as provided herein, the 
          Corporation shall promptly, but in no event more than 3 days 
          following such adjustment, give each holder of Series III Preferred 
          Stock notice of such adjustment, certified by the chief financial 
          officer of the Corporation, setting forth the new Conversion Price, 
          the computation by which such adjustment was made and a brief 
          statement of the facts requiring such adjustment.

     m.   In the event that (i) (A) the Corporation shall fail for any reason 
          to deliver shares of Common Stock to a holder upon conversion of 
          the Series III Preferred Stock within the time period specified in 
          paragraph 2(a), or (B) the Corporation shall fail to remove any 
          restrictive legend on any certificates evidencing such shares of 
          Common Stock as and when required under Section 4.3 of the Stock 
          Purchase Agreement, and (ii) thereafter, such holder shall purchase 
          (in an open market transaction or otherwise) shares of Common Stock 
          to make delivery in satisfaction of a sale by such holder of (A) 
          all or part of the shares of Common Stock which such holder 
          anticipated receiving upon such conversion, or (B) all or a portion 
          of such unlegended shares of Common 

                               Page 62 of 87 Pages
<PAGE>

          Stock, as the case may be (in each case, the "Sold Shares"), then 
          the Corporation shall pay to such holder (in addition to any other 
          remedies available to the holder) the amount by which (x) such 
          holder's total purchase price (including brokerage commissions, if 
          any) for the shares of Common Stock so purchased shall exceed (y) 
          the net proceeds received by such holder from the sale of the Sold 
          Shares.  The Corporation shall make any payments required pursuant 
          to this paragraph (m) within five (5) days after the receipt of 
          written notice from a holder setting forth the calculation of the 
          amount due hereunder.

     c.   MANDATORY CONVERSION.  The Series III Preferred Stock shall 
automatically be converted into shares of Common Stock of the Corporation, 
without any act by the Corporation or the holders of such Preferred Stock, 
concurrently with the closing of any public offering by the Corporation of 
shares of Common Stock of the Corporation registered under the Securities Act 
of 1933, as amended, in which (1) the aggregate public offering price of the 
securities sold for cash by the Corporation in the offering is at least 
$5,000,000 or such lesser amount as may be approved by the holders of at 
least 66.67% of the shares of Preferred Stock then outstanding, and (2) the 
public offering price per share of Common Stock is at least $5.00 (as 
adjusted from time to time to reflect stock splits, dividends, 
recapitalizations, combinations or the like), or such lower amount as may be 
approved by the holders of 66.67% of the shares of Preferred Stock then 
outstanding.

     d.   DEFINITION.  All capitalized terms not otherwise defined herein 
shall have the definition ascribed to them in the Stock Purchase Agreement.

     e.   REMEDIES CUMULATIVE.  The remedies provided in this Certificate of 
Designation shall be cumulative and in addition to all other remedies 
available, at law or in equity (including a decree of specific performance 
and/or other injunctive relief), and nothing herein shall limit a holder's 
right to pursue actual damages for any failure by the Corporation to comply 
with the terms of this Certificate of Designation.  The Corporation 
acknowledges that a breach by it of its obligations under this Certificate of 
Designation shall cause irreparable harm to the holders of the Series III 
Preferred Stock and that the remedy at law for any such breach may be 
inadequate.  The Corporation agrees, in the event of any such breach or 
threatened breach, that each holder shall be entitled, in addition to all 
other available remedies, to an injunction restraining any breach, without 
the necessity of showing economic loss and without any bond or other security 
being required.

     FURTHER RESOLVED, that W. Edward McConaghay, President of the 
     Corporation, be, and hereby is, authorized and directed to make and 
     execute a Certificate of Designation embracing the foregoing resolutions 
     and to cause such Certificate of Designation to be filed with the office 
     of the Secretary of State of the State of Minnesota.

          THIS CERTIFIES THAT, for value received, SPECIAL SITUATIONS PRIVATE 
EQUITY FUND L.P. (the "Holder") or registered permitted assigns is entitled 
to purchase from TELIDENT, INC., (the "Corporation"), a corporation organized

Termination Date (as hereinafter defined) 200,000 fully paid and 
nonassessable shares of the Corporation's Common Stock, par value $0.08 per 
share (the "Warrant Stock") (subject to adjustment as noted below).  This 
Warrant has been issued in connection with the purchase from the Corporation 
of series III convertible preferred shares of the Corporation (the "Series 
III Preferred Stock") pursuant to a Stock Purchase Agreement dated April 13, 
1998 (the "Purchase Agreement"), by and among the Corporation, certain other 
equity investors and the Holder. For purposes of this Warrant, "Termination 
Date" shall mean 5:00 P.M. Minneapolis time on the second anniversary of the 
Closing Date unless extended as provided herein.  All capitalized terms not 
otherwise defined herein shall have the meaning ascribed to them in the 
Purchase Agreement.

          The purchase price of the Warrant Stock upon exercise of the 
Warrant shall be $3.125 per share (the "Purchase Price").  The Purchase Price 
shall be subject to adjustment as provided below.

          The Holder may sell, transfer, assign or otherwise dispose of any 
of its rights or obligations hereunder in accordance with applicable 
securities laws.

          This Warrant is subject to the following provisions, terms and 
conditions:

          1.   This Warrant may be exercised by the Holder hereof, in whole 
or in part, by written notice of exercise delivered to the Corporation along 
with the surrender of this Warrant (properly endorsed if required) at the 
principal office of the Corporation and upon payment to it by wire transfer 
of the Purchase Price for the number of shares of Warrant Stock which the 
Holder elects to purchase.  The Corporation agrees that the shares so 
purchased shall be and are deemed to be issued to the Holder hereof as the 
record owner of 

                               Page 65 of 87 Pages
<PAGE>

such shares as of the close of business on the date on which this Warrant 
shall have been surrendered and payment made for such shares as aforesaid.  
Subject to the provisions of the next succeeding paragraph, certificates for 
the Warrant Stock so purchased shall be delivered to the Holder hereof within 
a reasonable time, not exceeding two (2) days, after the rights represented 
by this Warrant shall have been so exercised, and, unless this Warrant has 
expired, a new Warrant representing the number of shares, if any, with 
respect to which this Warrant shall not then have been exercised shall also 
be delivered to the Holder hereof within such time.

          2.   Subject to the provisions of this Section 2, the Corporation 
shall have the right to require the Holder to exercise this Warrant (the 
"Call"), upon the Corporation's giving written notice to the Holder (the 
"Call Notice").  The Call may be exercised at the option of the Corporation 
at any time if the bid price of the Corporation's Common Stock on The NASDAQ 
SmallCap Market (or such other market or exchange as such Common Stock may be 
traded) has equaled or exceeded $4.375 per share (equitably adjusted to 
reflect stock splits, stock dividends, reorganizations, consolidations and 
similar changes hereafter effected) for a period of at least ten (10) 
consecutive trading days immediately prior to the Call Notice.  Upon receipt 
of such Call Notice, the Holder (i) shall surrender this Warrant to the 
Corporation together with payment of the Purchase Price for the number of 
shares of Warrant Stock to be purchased on or before the fifteenth day 
following the Corporation's giving of the Call Notice to the Holder, or (ii) 
shall decline to exercise the Warrant, in whole or in part, whereupon the 
Warrant shall immediately terminate with respect to any shares which the 
Holder does not exercise.  If Holder purchases less than all of the Warrant 
Stock within such fifteen (15) day period, the Warrant shall immediately 
terminate with respect to all shares of Warrant Stock not so purchased.  
Notwithstanding anything to the contrary contained herein, the Corporation 
cannot exercise the Call at any time that the Registration Statement required 
to be filed under Section 11.1 of the Purchase Agreement is not effective.  
Additionally, the 15-day period described herein shall be extended by the 
number of days during a period that such Registration Statement is subject to 
a stop order or is otherwise not in effect or the holder is advised that the 
prospectus included therein contains a material misstatement or omission.

          3.   The Corporation covenants and agrees that, the Warrant Stock 
will, upon issuance, be duly authorized and issued, fully paid and 
nonassessable.  The Corporation further covenants and agrees that during the 
period within which the rights represented by this Warrant may be exercised, 
the Corporation will, at all times have authorized and reserved for the 
purpose of issue or transfer upon exercise of the rights evidenced by this 
Warrant, a sufficient number of shares of Warrant Stock to provide for the 
exercise of the rights represented by this Warrant.

          4.   The above provisions are, however, subject to the following:

                               Page 66 of 87 Pages
<PAGE>

          (a)  The Purchase Price shall, from and after the date of issuance 
of this Warrant, be subject to adjustment from time to time as hereinafter 
provided.  Upon each adjustment of the Purchase Price, the Holder of this 
Warrant shall thereafter be entitled to purchase, at the Purchase Price 
resulting from such adjustment, the number of shares obtained by multiplying 
the Purchase Price in effect immediately prior to such adjustment by the 
number of shares purchasable pursuant hereto immediately prior to such 
adjustment and dividing the product thereof by the Purchase Price resulting 
from such adjustment.

          (b)  Except for (i) options to purchase shares of Common Stock 
pursuant to the Corporation's 1988 Stock Option Plan adopted by the 
Corporation which are outstanding as of the date hereof and except for shares 
of Common Stock issued upon the exercise of such options granted pursuant to 
such plan and (ii) shares of Common Stock issued upon conversion of the 
Series III Preferred Stock or exercise of this Warrant or other warrants or 
rights to purchase the securities of the Corporation outstanding as of the 
date hereof, if and whenever the Corporation shall issue or sell any 
additional shares of its Common Stock for a consideration per share less than 
the Purchase Price in effect immediately prior to the time of such issue or 
sale, then, forthwith upon such issue or sale, the Purchase Price shall be 
reduced to such lesser price as is determined by multiplying the Purchase 
Price in effect immediately prior thereto by a fraction, the numerator of 
which shall be the sum of the number of shares of Common Stock outstanding 
immediately prior to the issuance or sale of such additional shares and the 
number of shares of Common Stock which the aggregate consideration received 
(determined in accordance with this paragraph 4) for the issuance or sale of 
such additional shares would purchase at the Purchase Price then in effect, 
and the denominator of which shall be the number of shares of Common Stock 
outstanding immediately after the issuance or sale of such additional shares.

          (c)  For the purposes of paragraph (b), the following provisions 
(i) to (iii), inclusive, shall also be applicable:

          (i)  In case at any time the Corporation shall grant (whether 
     directly or by assumption in a merger or otherwise) any rights to 
     subscribe for or to purchase, or any options for the purchase of, (aa) 
     Common Stock or (bb) any obligations or any shares of stock of the 
     Corporation which are convertible into or exchangeable for Common Stock 
     (any of such obligations or shares of stock being hereinafter called 
     "Convertible Securities") whether or not such rights or options or the 
     right to convert or exchange any such Convertible Securities are 
     immediately exercisable, and the price per share for which Common Stock 
     is issuable upon the exercise of such rights or options or upon 
     conversion or exchange of such Convertible Securities (determined by 
     dividing (cc) the total amount, if any, received or receivable by the 
     Corporation as consideration for the granting of such rights or options, 
     plus the minimum aggregate amount of additional consideration payable to 
     the Corporation upon the exercise of such rights or options, plus, in 
     the case of such rights or options which relate to 

                               Page 67 of 87 Pages
<PAGE>

     Convertible Securities, the minimum aggregate amount of additional 
     consideration, if any, payable upon the issue or sale of such 
     Convertible Securities and upon the conversion or exchange thereof, by 
     (dd) the total maximum number of shares of Common Stock issuable upon 
     the exercise of such rights or options or upon the conversion or 
     exchange of all such Convertible Securities issuable upon the exercise 
     of such rights or options) shall be less than the Purchase Price in 
     effect immediately prior to the time of the granting of such rights or 
     options on the date of such grant, then the total maximum number of 
     shares of Common Stock issuable upon the exercise of such rights or 
     options or upon conversion or exchange of the total maximum amount of 
     such Convertible Securities issuable upon the exercise of such rights or 
     options shall (as of the date of granting of such rights or options) be 
     deemed to be outstanding and to have been issued for such price per 
     share.  No further adjustments of the Purchase Price shall be made upon 
     the actual issue of such Common Stock or of such Convertible Securities 
     upon exercise of such rights or options or upon the actual issue of such 
     Common Stock upon conversion or exchange of such Convertible Securities.

          (ii)  In case the Corporation shall issue or sell (whether directly 
     or by assumption in a merger or otherwise) any Convertible Securities, 
     whether or not the rights to exchange or convert thereunder are 
     immediately exercisable, and the price per share for which Common Stock 
     is issuable upon such conversion or exchange (determined by dividing 
     (aa) the total amount received or receivable by the Corporation as 
     consideration for the issue or sale of such Convertible Securities, plus 
     the minimum aggregate amount of additional consideration, if any, 
     payable to the Corporation upon the conversion or exchange thereof, by 
     (bb) the total maximum number of shares of Common Stock issuable upon 
     the conversion or exchange of all such Convertible Securities) shall be 
     less than the Purchase Price in effect immediately prior to the time of 
     such issue or sale, then the total maximum number of shares of Common 
     Stock issuable upon conversion or exchange of all such Convertible 
     Securities shall (as of the date of the issue or sale of such 
     Convertible Securities) be deemed to be outstanding and to have been 
     issued for such price per share, provided that if any such issue or sale 
     of such Convertible Securities is made upon exercise of any rights to 
     subscribe for or to purchase or any option to purchase any such 
     Convertible Securities for which adjustments of the Purchase Price have 
     been or are to be made pursuant to other provisions of this paragraph 
     (c), no further adjustment of the Purchase Price shall be made by reason 
     of such issue or sale.

          (iii)  In case any shares of Common Stock or Convertible Securities 
     or any rights or options to purchase any such Common Stock or 
     Convertible Securities shall be issued or sold for cash, the 
     consideration received therefor shall be deemed to be the amount 
     received by the Corporation therefor, without deduction therefrom of any 
     expenses incurred or any underwriting commissions, discounts or 
     concessions paid 

                               Page 68 of 87 Pages
<PAGE>

      or allowed by the Corporation in connection therewith.  In case any 
     shares of Common Stock or Convertible Securities or any rights or 
     options to purchase any such Common Stock or Convertible Securities 
     shall be issued or sold for a consideration other than cash, the amount 
     of the consideration other than cash received by the Corporation shall 
     be deemed to be the fair value of such consideration as determined by 
     the Board of Directors of the Corporation, without deducting therefrom 
     any expenses incurred or any underwriting commissions, discounts or 
     concessions paid or allowed by the Corporation in connection therewith.  
     In case any shares of Common Stock or Convertible Securities or any 
     rights or options to purchase such Common Stock or Convertible 
     Securities shall be issued in connection with any merger or 
     consolidation in which the Corporation is the surviving corporation, the 
     amount of consideration therefor shall be deemed to be the fair value as 
     determined by the Board of Directors of the Corporation of such portion 
     of the assets and business of the non-surviving corporation or 
     corporations as such Board shall determine to be attributable to such 
     Common Stock, Convertible Securities, rights or options, as the case may 
     be.  In the event of any consolidation or merger of the Corporation in 
     which the Corporation is not the surviving corporation or in the event 
     of any sale of all or substantially all of the assets of the Corporation 
     for stock or other securities of any other corporation, the Corporation 
     shall be deemed to have issued a number of shares of its Common Stock 
     for stock or securities of the other corporation computed on the basis 
     of the actual exchange ratio on which the transaction was predicated and 
     for a consideration equal to the fair market value on the date of such 
     transaction of such stock or securities of the other corporation, and if 
     any such calculation results in adjustment of the Purchase Price, the 
     determination of the number of shares of Common Stock issuable upon 
     exercise of this Warrant immediately prior to such merger, conversion or 
     sale, for purposes of paragraph (g) below, shall be made after giving 
     effect to such adjustment of the Purchase Price.

          (d)  In case the Corporation shall (i) declare a dividend upon the 
Common Stock payable in Common Stock (other than a dividend declared to 
effect a subdivision of the outstanding shares of Common Stock, as described 
in paragraph (e) below) or Convertible Securities, or in any rights or 
options to purchase Common Stock or Convertible Securities, or (ii) declare 
any other dividend or make any other distribution upon the Common Stock 
payable otherwise than out of earnings or earned surplus, then thereafter the 
Holder of this Warrant upon the exercise hereof will be entitled to receive 
the number of shares of Warrant Stock to which Holder shall be entitled upon 
such exercise, and, in addition and without further payment therefor, each 
dividend described in clause (i) above and each dividend or distribution 
described in clause (ii) above which Holder would have received by way of 
dividends or distributions if continuously since the issuance of this 
Warrant, Holder (i) had been the record Holder of the number of shares of 
Warrant Stock then received, and (ii) had retained all dividends or 
distributions in stock or securities (including Common Stock or Convertible 
Securities, or in any rights or options to purchase 

                               Page 69 of 87 Pages
<PAGE>

any Common Stock or Convertible Securities) payable in respect of such 
Warrant Stock or in respect of any stock or securities paid as dividends or 
distributions and originating directly or indirectly from such Warrant Stock. 
 For the purposes of the foregoing, a dividend or distribution other than in 
cash shall be considered payable out of earnings or earned surplus only to 
the extent that such earnings or earned surplus are charged an amount equal 
to the fair value of such dividend or distribution as determined by the Board 
of Directors of the Corporation.

          (e)  In case the Corporation shall at any time subdivide its 
outstanding shares of Common Stock into a greater number of shares, the 
Purchase Price in effect immediately prior to such subdivision shall be 
proportionately reduced, and conversely, in case the outstanding shares of 
Common Stock of the Corporation shall be combined into a smaller number of 
shares, the Purchase Price in effect immediately prior to such combination 
shall be proportionately increased.

          (f)  If (i) the purchase price provided for in any right or option 
referred to in clause (i) of paragraph (c), or (ii) the additional 
consideration, if any, payable upon the conversion or exchange of Convertible 
Securities referred to in clause (i) or clause (ii) of paragraph (c), or 
(iii) the rate at which any Convertible Securities referred to in clause (i) 
or clause (ii) of paragraph (c) are convertible into or exchangeable for 
Common Stock shall change at any time (other than under or by reason of 
provisions designed to protect against dilution), the Purchase Price then in 
effect shall forthwith be increased or decreased to such Purchase Price which 
would have been obtained had the adjustments made upon the issuance of such 
rights, options or Convertible Securities been made upon the basis of (i) the 
issuance of the number of shares of Common Stock theretofore actually 
delivered upon the exercise of such options or rights or upon the conversion 
or exchange of such Convertible Securities, and the total consideration 
received therefor, and (ii) the issuance at the time of such change of any 
such options, rights or Convertible Securities then still outstanding for the 
consideration, if any, received by the Corporation therefor and to be 
received on the basis of such changed price; and on the expiration of any 
such option or right or the termination of any such right to convert or 
exchange such Convertible Securities, the Purchase Price then in effect 
hereunder shall forthwith be increased to such Purchase Price which would 
have obtained had the adjustments made upon the issuance of such rights or 
options or Convertible Securities been made upon the basis of the issuance of 
the shares of Common Stock theretofore actually delivered (and the total 
consideration received therefor) upon the exercise of such rights or options 
or upon the conversion or exchange of such Convertible Securities.  If the 
purchase price provided for in any such right or option referred to in clause 
(i) of paragraph (c) or the rate at which any Convertible Securities referred 
to in clause (i) or clause (ii) of paragraph (c) are convertible into or 
exchangeable for Common Stock shall decrease at any time under or by reason 
of provisions with respect thereto designed to protect against dilution, then 
in case of the delivery of Common Stock upon the exercise of any such right 
or option or upon conversion or exchange of any such Convertible 

                               Page 70 of 87 Pages
<PAGE>

Security, the Purchase Price then in effect hereunder shall forthwith be 
decreased to such Purchase Price as would have obtained had the adjustments 
made upon the issuance of such right, option or Convertible Securities been 
made upon the basis of the issuance of (and the total consideration received 
for) the shares of Common Stock delivered as aforesaid.

          (g)  If any capital reorganization or reclassification of the 
capital stock of the Corporation, or consolidation or merger of the 
Corporation with another corporation, or the sale of all or substantially all 
of its assets to another corporation shall be effected in such a way that the 
holders of Common Stock shall be entitled to receive stock, securities or 
assets with respect to or in exchange for Common Stock, then, as a condition 
of such reorganization, reclassification, consolidation, merger or sale, 
lawful and adequate provision shall be made whereby the Holder hereof shall 
thereafter have the right to purchase and receive, upon the basis and upon 
the terms and conditions specified in this Warrant and in lieu of the shares 
of the Warrant Stock of the Corporation immediately theretofore purchasable 
and receivable upon the exercise of the rights represented hereby, such 
shares of stock, securities or assets as may be issued or payable with 
respect to or in exchange for a number of outstanding shares of such Common 
Stock equal to the number of shares of such stock immediately theretofore 
purchasable and receivable upon the exercise of the rights represented hereby 
had such reorganization, reclassification, consolidation, merger or sale not 
taken place, and in any such case appropriate provision shall be made with 
respect to the rights and interests of the Holder of this Warrant to the end 
that the provisions hereof (including without limitation provisions for 
adjustments of the Purchase Price and of the number of shares purchasable 
upon the exercise of this Warrant) shall thereafter be applicable, as nearly 
as may be, in relation to any shares of stock, securities or assets 
thereafter deliverable upon the exercise hereof.  The Corporation shall not 
effect any such consolidation, merger or sale, unless prior to the 
consummation thereof the successor corporation (if other than the 
Corporation) resulting from such consolidation or merger or the corporation 
purchasing such assets shall assume, by written instrument executed and 
mailed to the registered Holder hereof at the last address of Holder 
appearing on the books of the Corporation, the obligation to deliver to 
Holder such shares of stock, securities or assets as, in accordance with the 
foregoing provisions, the Holder may be entitled to purchase.

          (h)  In case any time:

               (1)  the Corporation shall declare any cash dividend on its 
     Common Stock or preferred stock at a rate in excess of the rate of the 
     last cash dividend theretofore paid;

               (2)  the Corporation shall pay any dividend payable in stock 
     upon its Common Stock or make any distribution (other than regular cash 
     dividends) to the holders of its Common Stock or preferred stock;

                               Page 71 of 87 Pages
<PAGE>

               (3)  the Corporation shall offer for subscription pro rata to 
     the holders of its Common Stock or preferred stock any additional shares 
     of stock of any class or other rights;

               (4)  there shall be any capital reorganization, or 
     reclassification of the capital stock of the Corporation, or 
     consolidation or merger of the Corporation with, or sale of all or 
     substantially all of its assets to, another corporation; or

               (5)  there shall be a voluntary or involuntary dissolution, 
     liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give written 
notice, by first-class mail, postage prepaid, addressed to the registered 
Holder of this Warrant at the address of the Holder as shown on the books of 
the Corporation, of the date on which (aa) the books of the Corporation shall 
close or a record shall be taken for such dividend, distribution or 
subscription rights, or (bb) such reorganization, reclassification, 
consolidation, merger, sale, dissolution, liquidation or winding up shall 
take place, as the case may be.  Such notice shall also specify the date as 
of which the holders of Common Stock of record shall participate in such 
dividend, distribution or subscription rights, or shall be entitled to 
exchange their Common Stock for securities or other property deliverable upon 
such reorganization, reclassification, consolidation, merger, sale, 
dissolution, liquidation or winding up, as the case may be.  Such written 
notice shall be given at least 20 days prior to the action in question and 
not less than 20 days prior to the record date or the date on which the 
Corporation's transfer books are closed in respect thereto.

          (i)  If any event occurs as to which in the opinion of the Board of 
Directors of the Corporation the other provisions of this paragraph 4 are not 
strictly applicable or if strictly applicable would not fairly protect the 
purchase rights of the Holder of this Warrant or of Warrant Stock in 
accordance with the essential intent and principles of such provisions, then 
the Board of Directors shall make an adjustment in the application of such 
provisions, in accordance with such essential intent and principles, so as to 
protect such purchase rights as aforesaid.

          (j)  No fractional shares of Warrant Stock shall be issued upon the 
exercise of this Warrant, but, instead of any fraction of a share which would 
otherwise be issuable, the Corporation shall pay a cash adjustment (which may 
be effected as a reduction of the amount to be paid by the Holder hereof upon 
such exercise) in respect of such fraction in an amount equal to the same 
fraction of the Market Price per share of Common Stock as of the close of 
business on the date of the notice required by paragraph 1 above.  "Market 
Price" shall mean, if the Common Stock is traded on a securities exchange, 
the NASDAQ National Market or on The NASDAQ SmallCap Market, the closing 
price of the Common Stock on 

                               Page 72 of 87 Pages
<PAGE>

such exchange, the NASDAQ National Market or the NASDAQ SmallCap Market, or, 
if the Common Stock is otherwise traded in the over-the-counter market, the 
closing price, in each case averaged over a period of 20 consecutive business 
days prior to the date as of which "Market Price" is being determined.  If at 
any time the Common Stock is not traded on an exchange, the NASDAQ National 
Market or The NASDAQ SmallCap Market, or otherwise traded in the 
over-the-counter market, the "Market Price" shall be deemed to be the higher 
of (i) the book value thereof as determined by any firm of independent public 
accountants of recognized standing selected by the Board of Directors of the 
Corporation as of the last day of any month ending within 60 days preceding 
the date as of which the determination is to be made, or (ii) the fair value 
thereof determined in good faith by the Board of Directors of the Corporation 
as of a date which is within 15 days of the date as of which the 
determination is to be made.

          (k)  Whenever the number of shares purchasable upon the exercise of 
this Warrant or the Purchase Price is adjusted, as provided herein, the 
Corporation shall promptly, but in no event more than 3 days following such 
adjustment, give the Holder notice of such adjustment, certified by the chief 
financial officer of the Corporation, setting forth the number of shares 
purchasable upon exercise of the Warrant and the Purchase Price, the 
computation by which such adjustment was made and a brief statement of the 
facts requiring such adjustment.

          5.   As used herein, the term "Common Stock" shall include the 
Corporation's presently authorized Common Stock and shall also include any 
capital stock of any class of the Corporation hereafter authorized which 
shall not be limited to a fixed sum or percentage in respect of the rights of 
the Holders thereof to participate in dividends or in the distribution of 
assets upon the voluntary or involuntary liquidation, dissolution or winding 
up of the Corporation; provided that the shares purchasable pursuant to this 
Warrant shall include shares designated as Common Stock of the Corporation on 
the date of original issue of this Warrant or, in the case of any 
reclassification of the outstanding shares thereof, the stock, securities or 
assets provided for in paragraph 4(g) above.

          6.   So long as this Warrant remains outstanding, the Corporation 
will not issue any additional capital stock of any class preferred as to 
dividends or as to the distribution of assets upon voluntary or involuntary 
liquidation, dissolution or winding up, unless the rights of the holders 
thereof shall be limited to a fixed sum or percentage of par, liquidation or 
redemption value in respect of participation in dividends and in the 
distribution of such assets.

          7.   This Warrant shall not entitle the Holder hereof to any voting 
rights or other rights as a stockholder of the Corporation.

                               Page 73 of 87 Pages
<PAGE>

          8.   The Holder of this Warrant, by acceptance hereof, agrees to 
give written notice to the Corporation before transferring this Warrant or 
transferring any unregistered Warrant Stock issuable or issued upon the 
exercise hereof of Holder's intention to do so, describing briefly the manner 
of any proposed transfer of this Warrant or Holder's intention as to the 
disposition to be made of shares of Common Stock issuable or issued upon the 
exercise hereof. Holder shall also provide the Corporation with an opinion of 
counsel satisfactory to the Corporation to the effect that the proposed 
transfer of this Warrant or disposition of unregistered shares may be 
effected without registration or qualification (under any Federal or State 
law) of this Warrant or the shares of Common Stock issuable or issued upon 
the exercise hereof.  Upon receipt of such written notice and opinion by the 
Corporation, Holder shall be entitled to transfer this Warrant, or to 
exercise this Warrant in accordance with its terms and dispose of the shares 
received upon such exercise or to dispose of shares of Common Stock received 
upon the previous exercise of this Warrant, provided that an appropriate 
legend respecting the aforesaid restrictions on transfer and disposition may 
be endorsed on this Warrant or the certificates for such shares.  The Holder 
and any assignee of the Holder shall be entitled to the registration rights 
provided in Section 11 of the Purchase Agreement.

          9.   Subject to the provisions of paragraph 8 hereof, this Warrant 
and all rights hereunder are transferable, in whole or in part, by the Holder 
hereof in person or by duly authorized attorney, upon surrender at the 
principal office of the Corporation of this Warrant properly endorsed.  Each 
taker and holder of this Warrant, by taking or holding the same, consents and 
agrees that the bearer of this Warrant, when endorsed, may be treated by the 
Corporation and all other persons dealing with this Warrant as the absolute 
owner hereof for any purpose and as the person entitled to exercise the 
rights represented by this Warrant, or to the transfer hereof on the books of 
the Corporation, any notice to the contrary notwithstanding; but until such 
transfer on such books, the Corporation may treat the registered Holder 
hereof as the owner for all purposes.

          10.  This Warrant is exchangeable, upon the surrender hereof by the 
Holder hereof at the principal office of the Corporation, for new Warrants of 
like tenor representing in the aggregate the right to subscribe for and 
purchase the number of shares which may be subscribed for and purchased 
hereunder, each of such new Warrants to represent the right to subscribe for 
and purchase such number of shares as shall be designated by said Holder 
hereof at the time of such surrender.

                                   ESCROW AGREEMENT
     This Agreement is entered into this 13th day of April, 1998, by and 
among Telident, Inc. (the "Company"), FAMCO III LIMITED LIABILITY COMPANY 
(the "Purchaser"), and Manchester Companies, Inc. (the "Escrow Agent").

     WHEREAS, the Company has undertaken to offer and sell to the Purchaser 
in a private placement transaction shares of its series III convertible 
preferred stock and warrants to purchase shares of its common stock (together 
the "Securities"), pursuant to the terms of a Stock Purchase Agreement, dated 
April 13, 1998 by and among the Company, the Purchaser and a certain other 
investor (the "Purchase Agreement"); and

     WHEREAS, as a condition of entering into the Purchase Agreement, the 
Purchaser requires and the Company agrees to place in escrow with the Escrow 
Agent the purchase price of the Securities (the "Purchase Price"), the stock 
certificate representing the shares of Series III Preferred Stock (the "Stock 
Certificate") and the warrant (the "Warrant") to be purchased by the 
Purchaser; and

     WHEREAS, the Company, the Purchaser and the Escrow Agent desire to enter 
into an agreement with respect to the escrow of the Purchase Price, the Stock 
Certificate and the Warrant.

     NOW, THEREFORE, in consideration of the premises and agreements set 
forth herein, the parties hereto agree as follows:

Q.   ITEMS TO BE PLACED IN ESCROW.  The Purchase Price, the Stock Certificate 
and the Warrant shall be delivered to the Escrow Agent within one (1) 
business day following the execution of the Purchase Agreement, and shall be 
retained in escrow by the Escrow Agent in an account which allows the Escrow 
Agent to individually account for funds received and any interest earned on 
such funds (the "Escrow Account").

R.   INVESTMENT OF FUNDS.  All funds held by the Escrow Agent pursuant to 
this Agreement shall constitute trust property for the purposes for which 
they are held.  The Escrow Agent shall invest all funds received from the 
Company in an interest bearing account.

S.   DISBURSEMENT OF FUNDS. Upon the Closing of the transaction set forth in 
the Purchase Agreement resulting from the satisfaction of the conditions of 
Closing in Section 7 thereof, the Purchaser shall cause the Escrow Agent  
promptly to release (a) the Purchase Price to the Company and (b) the Stock 
Certificate and the Warrant to the Purchaser.  If the Closing does not occur 
on or before May 8, 1998 (or such other later Closing Date as shall have been 
mutually agreed upon pursuant to Section 3 of the Purchase Agreement) or if 
the Purchaser 

                               Page 80 of 87 Pages
<PAGE>

receives notice on or before May 8, 1998, that the Company's Common Stock 
will no longer continue to be listed on the NASDAQ SmallCap Market, then the 
Purchaser shall cause the Escrow Agent promptly to release (y) the Purchase 
Price, and any interest thereon, to the Purchaser, and (z) the Stock 
Certificate and the Warrant to the Company, whereupon the Company will cancel 
such Securities.

     NAME OF PURCHASER                       PURCHASE PRICE
     -----------------         ----------------------------
     FAMCO III Limited Liability Company          $500,000

T.   TERM OF ESCROW.  The term of this escrow agreement (the "Term of 
Escrow") shall commence as of the date of this Agreement and terminate at 
5:00 p.m. New York time on May 8, 1998 (or such other later Closing Date as 
shall have been mutually agreed upon pursuant to Section 3 of the Purchase 
Agreement).  Upon termination hereof, whether after extension or otherwise, 
the Escrow Agent shall, without receipt of written notice from the Company, 
disburse the funds in the Escrow Account to the Purchaser and the Stock 
Certificate and the Warrant in the Escrow Account to the Company in the 
manner and upon the terms directed in Section 3 hereof.

U.   DUTY AND LIABILITY OF THE ESCROW AGENT; INDEMNIFICATION.  The sole duty 
of the Escrow Agent, other than as herein specified, shall be to receive the 
Purchase Price and the Stock Certificate and the Warrant and hold them 
subject to release, in accordance herewith, and the Escrow Agent shall be 
under no duty to determine whether the Company is complying with requirements 
of this Agreement.  The Escrow Agent may conclusively rely upon and shall be 
protected in acting upon any statement, certificate, notice, request, 
consent, order or other document believed by it to be genuine and to have 
been signed or presented by the Company.  The Escrow Agent shall have no duty 
or liability to verify any such statement, certificate, notice, request, 
consent, order or other document, and its sole responsibility shall be to act 
only as expressly set forth in this Agreement.  The Escrow Agent shall be 
under no obligation to institute or defend any action, suit or proceeding in 
connection with this Agreement unless first indemnified to its satisfaction.  
The Company and the Purchaser, jointly and severally, hereby indemnify and 
hold harmless the Escrow Agent from and against any and all loss, liability, 
cost, damage and expense, including, without limitation, reasonable 
attorneys' fees, which the Escrow Agent may suffer or incur by reason of any 
action, claim or proceeding brought against the Escrow Agent arising out of 
or relating in any way to this Agreement or any transaction to which this 
Agreement relates unless such action, claim or proceeding is the result of 
the willful misconduct of the Escrow Agent.  The Escrow Agent may consult 
counsel in respect of any question arising under this Agreement and the 
Escrow Agent shall not be liable for any action taken or omitted in good 
faith upon advice of such counsel.

V.   BINDING AGREEMENT AND SUBSTITUTION OF ESCROW AGENT.  The terms and 
conditions of this Agreement shall be binding on the assigns, creditors or 
transferees, or successors in interest, whether by operation of law or 
otherwise, of the parties hereto.  If, for any reason, the Escrow Agent named 
herein should be unable or unwilling to continue as such Escrow Agent, then 
the Company may substitute another escrow agent.

                      REPRESENTATIONS AND WARRANTIES OF COMPANY


     a.   REPRESENTATION 5.6(a).  The Company has a line of credit facility 
with Norwest Bank Minnesota, N.A.  This line of credit is secured by the 
Company's inventory and accounts receivable.

     b.   REPRESENTATION 5.8.  There is a pending NASDAQ inquiry into the 
continued listing of the Company's Common Stock on the NASDAQ SmallCap Market.

     c.   REPRESENTATION 5.14.  The following documents contain registration 
rights provisions:

          (1)  10% Series B Convertible Debenture issued by the Company in 
          connection with its May 1993 offering;

          (2)  Exercise, Conversion, Subscription and Purchase Agreement, 
          dated October 12, 1995, by and between the Company and Okabena 
          Partnership K ("Okabena");

          (3)  Warrant issued by the Company in connection with its April 
          1996 bridge financing;

          (4)  Warrant issued by the Company to R.J. Steichen & Co. in 
          connection with its August 1996 public offering; and

          (5)  Stock Purchase Agreement, dated July 23, 1997, by and between 
          the Company and FAMCO III Limited Liability Company.

     d.   REPRESENTATION 5.16.  The Company has received a letter from

          exercisable at $16.00 per share of such stock, issued by the 
          Company to Okabena in October 1995.  Okabena will not waive the 
          anti-dilution provisions contained in this warrant.  The 
          anti-dilution provisions only adjust the price at which the Warrant 
          can be exercised and not the number of shares for which it can be 
          exercised.

          connection with its May 1993 offering.  Such anti-dilution 
          provisions will not be waived by holders thereof.  Such debentures
