                                    Covenants
                                    ---------
 
         (a) Confidentiality. Each of the parties hereto agrees that it will not
use, or permit any of its affiliates or their respective agents or employees to
use, any of the information relating to any other party hereto furnished to it
in connection with the transactions contemplated herein which is not in the
public domain ("Information") in a manner or for a purpose detrimental to such
other party or otherwise than in connection with the transaction, and that they
will maintain the confidentiality of and not disclose the Information to any
person or entity, other than their respective affiliates, directors, officers,
employees, and authorized representatives and agents who are similarly bound to
maintain such confidentiality, except as may be required by judicial or
administrative process or, in the opinion of such party's regular counsel, by
other requirements of Law. Each party hereto also agrees to promptly return to
the party from whom originally received all original and duplicate copies of
written materials containing Information should the transactions contemplated



                                       6



herein not occur. A party hereto shall be deemed to have satisfied its
obligations to hold the Information confidential if it exercises the same care
as it takes with respect to its own similar information. Each party hereto
agrees that it will not (nor will it permit any of its affiliates or their
respective agents or employees to), intentionally characterize any other party's
(or its affiliates') rationale or business purpose for entering into this
Agreement or consummating the transactions contemplated hereby in a manner which
causes economic loss to, or damage to the reputation of, another party.

         (b) Filings; Consents; Removal of Objections. Subject to the terms and
conditions herein provided, each party hereto shall, where reasonably within its
control, use its commercially reasonable efforts to take or cause to be taken
all actions necessary, proper or advisable under applicable Law to consummate
and make effective, as soon as reasonably practicable, the transactions
contemplated hereby, including without limitation obtaining all Consents of any
person or entity required in connection with the consummation of the
transactions contemplated herein. Without limiting the foregoing, MAM agrees to
use its good faith best efforts to ensure that any redomestication of MidAmerica
Life Insurance Company ("MALICO") to Minnesota does not result in the Minnesota
Department of Commerce ordering or otherwise causing the cancellation of the
fronting arrangements provided for in that certain Reinsurance and Assumption
Agreement dated as of May 1, 1996 among MAM, MALICO and Provident Life (the
"Reinsurance Agreement").

         (c) Public Announcements. None of the parties hereto shall make any
public announcement with respect to the transactions contemplated herein without
the prior written consent of the other parties, which consent shall not be
unreasonably withheld or delayed; provided, however, that any of the parties
hereto may at any time make any announcements which are required by applicable
Law so long as the party so required to make an announcement promptly upon
learning of such requirement notifies the other parties of such requirement and
discusses with the other parties in good faith the exact proposed wording of any
such announcement.

         (d) Guaranty of Payment and Performance. Subject only to the Closing
occurring, Provident hereby guarantees the full and timely payment and
performance of any and all obligations of NIA and ABC, contractual or otherwise
(including any arising in relation to any trust or other account controlled by
either of them) arising after the Effective Time, to MAM or any of its
affiliates, or which have been guaranteed by MAM or any of its affiliates,
including (i) the obligations of NIA under that certain promissory note in an
original principal amount of $150,000, (ii) all obligations of NIA to MAM or
MALICO as a third party administrator therefore under certain Policy
Administration Agreements, and (iii) the obligations of NIA under the lease of
its facility. In connection with the foregoing, Provident hereby agrees to
advance, on May 10, 1996, to trust accounts held by NIA for the purpose of



                                       7



depositing premium received with respect to policies issued by any carrier for
which it acts as an administrator amounts by which such accounts may be
deficient (including with respect to the accounts of MAM and MALICO an aggregate
amount of Two Hundred Forty-Five Thousand Three Hundred and Sixty-Five Dollars
($245,365), being the aggregate amount by which the parties agree such a deficit
exists with respect to them), and to cause NIA to pay to MAM, MALICO and any
such other carriers any amounts due them in connection therewith (being in the
case of MAM and MALICO collectively the amount of Five Hundred Seventy-Two
Thousand Eight Hundred Nineteen Dollars ($572,819), net of any expense
authorized to be paid by NIA on behalf of MAM or MALICO in the ordinary course
of its business consistent with past practice, and plus or minus, as the case
may be, the proration settlement provided for in Section 4 of the Reinsurance
Agreement).

         (a) Methods of Termination. This Agreement may be terminated and the
transactions contemplated herein may be abandoned at any time but not later than
the Closing:

                  (i) By mutual written consent of MAM and Purchaser; or

                  (ii) By Purchaser on or after the Termination Date, if any of
         the conditions provided for in Section 5 shall not have been satisfied
         or waived in writing by Purchaser prior to such date; or

                  (iii) By MAM on or after the Termination Date, if any of the
         conditions provided for in Section 6 shall not have been satisfied or
         waived in writing by MAM prior to such date.

         (b) Procedure Upon Termination. In the event of termination and
abandonment pursuant to subsection 7(a), written notice thereof shall forthwith
be given to the other party or parties, and the provisions of this Agreement
shall terminate, and the transactions contemplated herein shall be abandoned,
without further action by any party hereto. If this Agreement is terminated as
provided herein: (i) each party will, upon request, redeliver all documents,
work papers and other material of any other party (and all copies thereof)
relating to the transactions contemplated herein, whether so obtained before or
after the execution hereof, to the party furnishing the same; (ii) the
confidentiality obligations of subsection 4(a) shall continue to be applicable.
No such termination shall relieve any party hereto of any liability arising from
breach of its obligations hereunder arising prior to such termination.

                                   SECTION 8.
                                   ----------
  
                          Survival and Indemnification
                          ----------------------------

         (a) Survival. The representations, warranties and covenants of each of
the parties hereto shall survive the Closing.




                                       11
  


       (b) Indemnification by Purchaser. Purchaser agrees to indemnify MAM and
MEI from and against any and all claims, loss, liability, cost, expense or
damage (collectively "Damage") suffered or incurred by it or MEI by reason of
(i) any untrue representation of, or breach of warranty by, Purchaser in this
Agreement, provided, however, that no claim for indemnity may be made pursuant
to this clause (i): (A) unless and until and then only to the extent that the
aggregate Damage exceeds $25,000, and (B) after May 1, 1998; and (ii) any
nonfulfillment of any covenant, agreement or undertaking of Purchaser in this
Agreement which by its terms is to remain in effect after the Closing and has
not been specifically waived in writing at the Closing by the party or parties
hereof entitled to the benefits thereof.

         (c) Indemnification by MAM and MEI. MAM and MEI agree to indemnify and
hold the Purchaser harmless from and against any and all Damage suffered or
incurred by it by reason of (i) any untrue representation of, or breach of
warranty by MAM or MEI in this Agreement, provided, however, that no claim for
indemnity may be made pursuant to this clause (i): (A) unless and until and then
only to the extent that the aggregate Damage exceeds $25,000 and (B) after May
1, 1998, or (ii) any nonfulfillment of any covenant, agreement or undertaking of
MAM or MEI in this Agreement which by its terms is to remain in effect after the
Closing and has not been specifically waived in writing at the Closing by the
party or parties hereto entitled to the benefits thereof.

         (d) Claims for Indemnification. The parties intend that all claims for
indemnification or payment hereunder be made as promptly as practicable by the
party seeking indemnification or payment (the "Indemnified Party"). Whenever any
claim for such indemnification or payment shall arise hereunder (a"claim") the
Indemnified Party shall promptly notify in writing the party from whom
indemnification or payment is sought (the "Indemnifying Party") of the claim
and, when known, the facts constituting the basis for such claim (a "Claim
Notice"). In the case of any Claim resulting from or in connection with any
claim or legal proceedings of a third party (a "Third Party Claim"), the Claim
Notice shall also specify, if known, the amount or an estimate of the amount of
the liability arising therefrom. If the Indemnifying Party is of the opinion
that the Indemnified Party is not entitled to indemnification or payment, or is
not entitled to indemnification in the amount stated in the Claim Notice, it
shall promptly deliver a written objection to such claim and written
specifications in reasonable detail of the aspects or details objected to, and
the grounds for such objection. Payment for any claim for indemnification shall
become due if and when the Indemnifying Party shall fail to timely object to the
Claim, shall admit the Claim in writing or in the event of an arbitral finding
in favor of the Indemnified Party.





                                       12




         (e) Right of Recovery. In the event that any party (or its affiliates)
is entitled to recover any sum (whether by payment, discount, credit or
otherwise) from any third party in respect of any matter for which a Claim for
could be or has been made against the other party, it shall promptly inform such
other party of such entitlement and shall take such steps as shall have been
reasonably requested by such other party both before and after making any Claim
in relation thereto to recover, at such other party's expense, such sum (keeping
such other party fully informed of the progress of any action taken). Any sum
recovered will reduce the amount of the Claim; in the event of the recovery
being delayed until after the Claim has been satisfied, the party paying the
Claim shall account to the other party in respect of any amount so recovered
(after deduction of all reasonable costs and expenses of the recovery) up to the
amount of the Claim. The failure to comply with this subsection shall not
prejudice the right of a party to pursue any Claim.

         (f) Matters Involving Third Parties. In connection with any Third Party
Claim, the Indemnifying Party will have the right to defend the Indemnified
Party against such Third Party Claim with counsel of its choice reasonably
satisfactory to the Indemnified Party provided that:

                  (i) the Indemnifying Party provides the Indemnified Party with
         evidence reasonably acceptable to the Indemnified Party that the
         Indemnifying Party will have the financial resources to defend against
         the Third Party Claim and fulfill its indemnification obligations
         hereunder,

                  A.  the Third Party Claim involves only money damages and 
                      does not seek an injunction or other equitable relief,

                  B.  settlement of, or an adverse judgment with respect to, the
                      Third Party Claim is not, in the good faith judgment of 
                      the Indemnified Party, likely to establish a precedential
                      custom or practice materially adverse to the continuing 
                      business interests of the Indemnified Party, and

                  C.  the Indemnifying Party conducts the defense of the Third 
                      Party Claim actively and diligently.

                  (ii) So long as the Indemnifying Party is conducting the
         defense of the Third Party Claim in accordance with subsection:

                  A.  the Indemnified Party may retain separate co-counsel at 
                      its sole cost and expense and participate in the defense
                      of the Third Party Claim, and  
                      


                                       13




                  B.   the Indemnifying Party will determine whether to consent 
                       to the entry of any judgment or enter into any settlement
                       with respect to the Third Party Claim subject to the 
                       prior written consent of the Indemnified Party (not to be
                       withheld unreasonably).

                  (iii) In the event any of the conditions in clause (i) above
         is or becomes unsatisfied, however,

                  A.   the Indemnified Party may defend against, and consent to
                       the entry of any judgment or enter into any settlement
                       with respect to, the Third Party Claim in any manner it
                       reasonably may deem appropriate (and the Indemnified
                       Party need not consult with, or obtain any consent from,
                       any Indemnifying Party in connection therewith),

                  B.   the Indemnifying Parties will reimburse the Indemnified
                       Party promptly and periodically for the reasonable costs
                       of defending against the Third Party Claim (including
                       reasonable attorneys' fees and expenses), and

                  C.   the Indemnifying Parties will remain responsible for any
                       Damages the Indemnified Party may suffer resulting from,
                       arising out of, relating to, in the nature of, or caused
                       by the Third Party Claim to the fullest extent provided
                       in this Section.


                                   SECTION 9.
                                   ----------

              Stock Transfers, Registration and Added Consideration
              -----------------------------------------------------

         (a) Requirements for Transfer of Purchaser Common Stock. Except for the
sale of Acquired Shares pursuant to a public offering, no Acquired Shares shall
be transferred by MEI until, unless waived by Purchaser, a written opinion
reasonably satisfactory to Purchaser in form and substance from counsel
reasonably satisfactory to Purchaser to the effect that the holder may transfer
such Acquired Shares without registration under the Securities Act of 1933 (the
"Securities Act") or any applicable state securities or blue sky laws.




                                       14




         (b) Common Stock Legend. Each certificate representing Acquired Shares
will be imprinted with legends in substantially the following form:

                  The shares represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended, or
                  under any state securities or blue sky laws and may not be
                  transferred in the absence of such registration or any
                  exception therefrom under such Act or under such state
                  securities or blue sky laws.

         (c) Demand Registrations.

                   (i)   In the event the Acquired Shares have not then
                         previously been registered either by Purchaser of its
                         own volition or pursuant to Section 9(d), then upon the
                         written request of MEI or any permitted (pursuant to
                         Section 9(a) hereof) transferee of all the Acquired
                         Shares (a "Requesting Holder") given at anytime on or
                         after May 1, 1997, the Purchaser, to the extent
                         permitted by law and subject to the terms hereof, shall
                         register the Acquired Shares pursuant to an effective
                         registration statement (a "Registration") under the
                         Securities Act. Any such Registration pursuant to this
                         Section 9(c) is hereinafter referred to as a "Demand
                         Registration." 

                   (ii)  If a Demand Registration is an underwritten offering,
                         no securities other than the Acquired Shares shall be
                         included among the securities covered by such Demand
                         Registration unless (i) the managing underwriters in
                         such Demand Registration advise the Purchaser and the
                         Requesting Holder in writing that in their opinion the
                         inclusion of the securities requested to be included in
                         such Demand Registration by other persons would not
                         materially adversely affect such offering.

                   (iii) Notwithstanding the foregoing, Purchaser shall have the
                         right to delay any such Demand Registration for up to
                         twenty (20) business days if Purchaser's counsel has
                         advised Purchaser (which advice shall be given as soon
                         as practicable) that certain material information (the
                         "Required Information") must be included in the
                         registration statement and Purchaser's Board of
                         Directors has in good faith, in view of pending



                                       15




                         negotiations or other developments regarding Purchaser
                         not otherwise required to be made public, determined 
                         that disclosure of the Required Information is not in 
                         the best interest of Purchaser. Under no circumstances 
                         will one or more delays pursuant to this clause extend
                         beyond thirty (30) calendar days from the date
                         Purchaser receives a Requesting Holder's request for a
                         Demand Registration. The Company agrees to use
                         reasonable commercial efforts to resolve any pending
                         negotiations or other developments referred to in this
                         clause as soon as reasonably practicable. Notice of
                         Purchaser's postponement of a Demand Registration
                         pursuant to this Clause shall be given to the
                         Requesting Holder within ten (10) business days of the
                         receipt of notice requesting a Demand Registration.

         (d) Other Registrations. If the Purchaser, at any time when the
Acquired Shares have not been previously registered either through Purchaser of
its own volition (it being agreed that Purchaser has the right to register the
Acquired Shares, on any appropriate form, including a Form S-3, if it so
desires) or pursuant to Section 9(c), proposes to register any shares of its
Common Stock under the Securities Act, whether for its own account or for others
(other than a registration statement on Form S-4 or S-8 or any successor or
similar forms), and the registration form to be used may be used for a offering
of Common Stock (an "Other Registration") and at the time thereof MEI or any
permitted (pursuant to Section 9(a) hereof) transferee thereof (herein a
"Holder") continues to hold any Acquired Shares which have not then previously
been the subject of a Registration, the Purchaser will give written notice of
such determination to the Holder, not less than ten (10) business days prior to
the projected filing of a Registration statement with the Securities Exchange
Commission (the "Commission"), and Purchaser, to the extent permitted by law,
shall include in such Registration all Acquired Shares held thereby.

         (e) Registration Procedures. If and whenever the Purchaser effects a
Registration pursuant to the provisions of Sections 9(c) or (d) or otherwise
determines to effect of its own volition a Registration which covers the
Acquired Shares, Purchaser will as expeditiously as reasonably possible:

               (i) prepare and file with the Commission a registration
         statement on the appropriate form with respect to the shares proposed
         to be registered and use its reasonable commercial efforts to cause
         such registration statement to become effective (provided that at least
         fifteen (15) business days before filing a registration statement or
         prospectus or




                                       16



         any amendments or supplements thereto, Purchaser shall furnish to the
         counsel selected by the Requesting Holder or Holder (the term "Holder"
         as used in the Sections (e), (f), (g) and (j) to include both
         Requesting Holders and Holders as defined) copies of all such documents
         proposed to be filed, which documents shall be subject to the prior
         review of such counsel reasonably prior to such filing);

               (ii) prepare and file with the Commission such amendments and
         supplements to such registration statement and the prospectus used in
         connection therewith as may be necessary to keep such registration
         statement effective for a period of the lesser of sixty (60) calendar
         days or the completion of the plan of distribution described in such
         prospectus and completion of the plan of distribution described in such
         prospectus and comply with the provisions of the Securities Act with
         respect to the disposition of all shares covered by such registration
         statement during such period in accordance with the intended methods of
         disposition set forth in such registration statement;

               (iii) furnish to the Holder such number of copies of such
         registration statement, each amendment and supplement thereto, the
         prospectus included in such registration statement (including each
         preliminary prospectus) and such other documents as the Holder may
         reasonably request in order to facilitate the disposition of the
         Acquired Shares;

               (iv) use its reasonable commercial efforts to register or qualify
         the Acquired Shares under such other securities or blue sky laws of
         such jurisdictions as the Holder reasonably requests and do any and all
         other acts and things which may be reasonably necessary or advisable to
         enable the Holder to consummate the disposition of the Acquired Shares
         in such jurisdictions (provided that Purchaser will not be required to
         (i) qualify generally to do business in any jurisdiction where it would
         not otherwise be required to qualify but for this subsection, (ii)
         subject itself to taxation in any such jurisdiction or (iii) consent to
         general service of process in any such jurisdiction, if in the opinion
         of counsel reasonably acceptable to the Holder, any of such actions in
         this clause (iv) would occur or result);

               (v) notify the Holder, at any time when a prospectus relating
         thereto is required to be delivered under the Securities Act, of the
         happening of any event or the receipt of any information as a result of
         which the prospectus included in such registration statement contains
         an untrue statement of a material fact or omits any fact necessary to
         make the statements therein not misleading, and prepare a




                                       17





         supplement or amendment to such prospectus so that, as thereafter
         delivered to the purchasers of such shares of Common Stock, such
         prospectus will not contain an untrue statement of a material fact or
         omit to state any fact necessary to make the statements therein not
         misleading;

               (vi) enter into such customary agreements (including, unless the
         Holder shall designate to the contrary in writing, underwriting
         agreements in customary form) and use its reasonable best efforts to
         take all such other actions in order to expedite or facilitate the
         disposition of the Acquired Shares;

               (vii) comply with all applicable rules and regulations of the
         Commission, and make available to its security holders, as soon as
         reasonably practicable, an earnings statement covering the period of at
         least twelve months beginning with the first day of the Purchaser's
         first full calendar quarter after the effective date of the
         registration statement, which earnings statement shall satisfy the
         provisions of Section 11 (a) of the Securities Act and Rule 158
         thereunder;

               (viii) permit the Holder to participate in the preparation of
         such registration statement and to require the insertion therein of
         written material concerning the Holder (and any person included
         therein) and the intended method of distribution, furnished to
         Purchaser in writing, which in the reasonable judgment of the Holder
         and its counsel should be included;

               (ix) in the event of the issuance of any stop order suspending
         the effectiveness of a registration statement, or of any order
         suspending or preventing the use of any related prospectus or
         suspending the qualification of any shares of Common Stock included in
         such registration statement for sale in any jurisdiction, use its
         reasonable best efforts to promptly obtain the withdrawal of such
         order;

               (x) cause, subject to applicable law and regulations, the
         Acquired Shares to be listed on each securities exchange on which
         shares of Purchaser Common Stock are then listed and, if not so listed,
         to be listed on the NASD automated quotation system; and

               (xi) use its best efforts to deliver an opinion of counsel to the
         Purchaser and a cold comfort letter from Purchaser's independent public
         accountants each in customary form and covering such matters of the
         type customarily covered by such opinions and letters in an
         underwritten offering.




                                       18



Any Registration which covers the Acquired Shares, whether effected pursuant to
Sections 9(c) or (d) hereof or otherwise, shall remain effective for a period of
not less than six (6) months.

         (f) Registration Expenses. All expenses to Purchaser or the Holder
(including reasonable attorneys fees but excluding the underwriting fees,
commission and other costs of any underwriter, broker or other person through
which the Acquired Shares are sold (collectively "Commissions), in connection
with any Registration in which any Acquired Shares are included will be paid by
Purchaser ("Registration Expenses"); provided that the Holder shall pay to
Purchaser to help defray such expense an amount equal to $5,000, payment to be
made promptly following demand made not more than ten (10) days prior to the
date such expense is incurred. In addition, Purchaser will pay its internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, and the expense of any liability
insurance.

         (g) Indemnification.

                   (i) Purchaser agrees to indemnify, to the extent permitted by
               law, the Holder, its officers and directors, each person who
               controls the Holder (within the meaning of the Securities Act)
               and each underwriter for any Registration against all Damages
               caused by any untrue or alleged untrue statement of material fact
               contained in any registration statement, prospectus or
               preliminary prospectus or any amendment thereof or supplement
               thereto or any omission or alleged omission of a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading, except insofar as the same are caused by
               or contained in any information furnished in writing to Purchaser
               by or on behalf of the Holder expressly for use therein or arises
               out of such the Holder's failure to deliver a copy of the final
               prospectus to the person asserting such claim or loss at or prior
               to the written confirmation of the sale of Acquired Shares by the
               Holder to such person, provided the untrue statement or omission
               was corrected in the final prospectus and the Purchaser furnished
               such person with sufficient copies of the final prospectus for
               delivery to such person.

                   (ii) Each Holder, by availing itself of registration pursuant
               to the terms hereof, agrees to indemnify the Purchaser, its
               directors and officers, each person who controls the Purchaser
               (within the meaning of the Securities Act) and each underwriter
               for any Registration against any Damages resulting from any
               untrue or alleged untrue statement



                                       19



               of material fact contained in the registration statement,
               prospectus or preliminary prospectus or any amendment thereof or
               supplement thereto or any omission or alleged omission of a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, but only if, and to the
               extent that, such statement or omission was in reliance upon and
               in conformity with written information furnished to the Purchaser
               by or on behalf of such Holder specifically for use in the
               preparation of such Registration statement.

                   (iii) Any person entitled to indemnification hereunder will:

                     A.  give prompt written notice to the indemnifying party of
                         any claim with respect to which it seeks 
                         indemnification and

                     B.  unless in such indemnified party's reasonable
                         judgment a conflict of interest between such
                         indemnified and indemnifying parties may exist with
                         respect to such claim, permit such indemnifying party
                         to assume the defense of such claim with counsel
                         reasonably satisfactory to the indemnified party.

                         If such defense is assumed, the indemnifying party
                         will not be subject to any liability for any
                         settlement made by the indemnified party without its
                         consent (but such consent will not be reasonably
                         withheld).

                   (iv) The indemnification provided for under this Agreement
               will remain in full force and effect regardless of any
               investigation made by or on behalf of the indemnified party or
               any officer, director or controlling person of such indemnified
               party and will survive the transfer of the Acquired Shares.

                   (v) In the event the indemnification provided for under this
               Agreement is unavailable for any reason other than the exceptions
               to indemnification contained herein, then the indemnifying party
               shall contribute to the amount paid or payable by the indemnified
               party as a result of such Damages in such proportion as is
               appropriate to reflect the relative fault of the indemnifying
               party on one hand and the indemnified party on the other hand in
               connection with the statements or omissions that resulted in such
               Damages, as well as any other relevant equitable considerations.
               Notwithstanding the foregoing, no person guilty of fraudulent
               misrepresentations (within the meaning of Section 11(f) of the



                                       20



               Securities Act) shall be entitled to contribution from any person
               who was not guilty of such fraudulent misrepresentation.

         (h) Selection of Underwriters. The Purchaser will have the right to
select the investment banker(s) and manager(s) to administer the offering
pursuant to any Registration.

         (i) SEC Filings; Public Information. So long as MAM or its affiliates
holds unregistered Acquired Shares, the Purchaser shall use commercially
reasonable efforts to file on a timely basis all reports required to be filed
pursuant to the Securities Exchange Act of 1934.

         (j) Additional Shares. In the event that the Acquired Shares are sold
by the Holder within six (6) months of the time a Registration statement filed
pursuant to Section 9(c) or 9(d) hereof becomes effective, and the Holder of the
Acquired Shares does not receive in such sale a price per share, net of
Commissions, of at least $6.65 per share (the "Guaranteed Net Price Per Share"),
then the Purchaser will promptly following the demand of the Holder issue to
such Holder such number of additional shares of the common stock of Purchaser
(the "Additional Shares"), which will also be covered by such Registration
statement, as shall be equal to the result of dividing (i) fifty thousand
(50,000) multiplied by the difference between the (A) Guaranteed Net Price Per
Share minus (B) the difference between ninety five percent (95%) of the gross
price per Acquired Share at which the Holder actually so effects the sale of the
Acquired Shares less actual Commissions which will be due on such sale to the
extent in excess of five percent (5%) (the "Actual Net Price Per Share") by (ii)
the Actual Net Price Per Share. For the avoidance of doubt, no Holder shall be
entitled to any additional shares pursuant to this Section unless it sells the
Acquired Shares within six (6) months of the date the Registration statement
covering the Acquired Shares becomes effective. A Holder shall demand the
issuance of any additional shares to which it is entitled pursuant to this
Section within a reasonable time following the sale of the Acquired Shares.

                                  SECTION 10.
                                  -----------
 
                            Miscellaneous Provisions.

however, that all such amendments and modifications must be in writing duly
executed by the parties hereto.

         (c) Waiver of Compliance; Consents. Any failure of a party to comply
with any obligation, covenant, agreement or condition herein may be expressly
waived in writing by the party entitled hereby to such compliance, but such
waiver or failure to insist upon strict compliance with such obligation,
covenant, agreement or condition shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure. No single or partial exercise
of a right or remedy shall preclude any other or further exercise thereof or of
any other right or remedy hereunder. Whenever this Agreement requires or permits
the consent by or on behalf of a party, such consent shall be given in writing
in the same manner as for waivers of compliance.

         (d) No Third Party Beneficiaries. Nothing in this Agreement shall
entitle any person or entity (other than a party hereto and his, her or its
respective successors and assigns permitted hereby) to any claim, cause of
action, remedy or right of any kind.

or to such other person or address as a party shall furnish to the other parties
hereto in writing in accordance with this subsection.

         (f) Assignment. This Agreement and all of the provisions hereof shall
be binding upon and inure to the benefit of the parties hereto and their
respective heirs, legal representatives, successors and permitted assigns, but
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned (whether voluntarily, involuntarily, by operation of law or
otherwise) by any of the parties hereto without the prior written consent of the
other parties.

         (g) Governing Law. This Agreement and the legal relations among the
parties hereto shall be governed by and construed in accordance with the
internal substantive laws of the State of




                                       23



Minnesota (without regard to the laws of conflict that might otherwise apply) as
to all matters, including without limitation matters of validity, construction,
effect, performance and remedies.

         (h) Counterparts. This Agreement may be executed simultaneously in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

         (i) Headings. The table of contents and the headings of the sections
and subsections of this Agreement are inserted for convenience only and shall
not constitute a part hereof.

         (j) Entire Agreement. The MAM Disclosure Schedule and the exhibits and
other writings referred to in this Agreement or in the MAM Disclosure Schedule
or any such exhibit or other writing are part of this Agreement, together they
embody the entire agreement and understanding of the parties hereto in respect
of the transactions contemplated by this Agreement and together they are
referred to as "this Agreement" or the "Agreement". There are no restrictions,
promises, warranties, agreements, covenants or undertakings, other than those
expressly set forth or referred to in this Agreement. This Agreement supersedes
all prior agreements and understandings between the parties with respect to the
transaction or transactions contemplated by this Agreement.

         (k) Informal Dispute Resolution. If there shall be any dispute,
controversy or claim ("Dispute"), between the MAM or its affiliates or Purchaser
and its affiliates arising out of, relating to, or connected with this
Agreement, the negotiation thereof or the breach or invalidity thereof, or the
provisions contained therein or omitted therefrom, the parties shall use their
best endeavors to resolve the matter on an amicable basis and in a manner fair
and equitable to the parties hereto. If one party notifies the other party that
a Dispute has arisen and the parties are unable to resolve such Dispute within a
period of fifteen (15) days from such notice, then the matter shall be referred
to the Chief Executive Officer of MAM and Purchaser for attempted resolution,
who shall have a further thirty (30) days to resolve the Dispute. Except to the
extent the sole relief sought is equitable, no recourse to litigation shall take
place unless and until such procedure has been followed.

         (l) Agreement as to Venue. Should any party or its affiliates wish to
initiate litigation, whether by was of claim, counter-claim or otherwise, with
respect to a Dispute, each of the parties agrees to, and to cause any such
affiliate to, submit in respect thereto to the jurisdiction of the federal court
sitting in Denver, Colorado if it has subject matter jurisdiction over such




                                       24



claim, or if it does not state courts sitting in such city. Each party also
agrees not to bring any action or proceeding with respect to any Dispute in any
other court. Each of the parties waives any defense of inconvenient forum to the
maintenance of any action or proceeding so brought and waives any bond, surety,
or other security that might be required of any other party with respect
thereto. Any party may make service on any other party by sending or delivering
a copy of the process to the party to be served at the address and in the manner
provided for the giving of notices in Section 10(e) hereof. Nothing in this
Section 10(1), however, shall affect the right of any party to serve legal
process in any other manner permitted by law or at equity.

         (m) Further Assurances. Each party hereto shall, before, at and after
Closing, execute and deliver such instruments and take such other actions as the
other party or parties, as the case may be, may reasonably require in order to
carry out the intent of this Agreement.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of the day and year first above written.
