as amended (the "Code");

         WHEREAS,  the Company has  established  and  maintains The ALLIED Group
Employee Stock  Ownership  Trust (the "Trust") and the Company has appointed the
Trustee to act as the trustee thereof pursuant to a trust agreement  between the
Company  and the Trustee  amended and  restated as of April 16, 1991 (the "Trust

created  thereunder  shall be invested in, among other things,  shares of common
stock of the Company  ("Common  Stock") or  convertible  preferred  stock of the
Company;

         WHEREAS,  the  Company has  previously  designated  85,000  shares as a
series  of  preferred  stock,  with  no par  value,  called  the  Series  C ESOP
Convertible  Preferred Stock, of which 75,753 shares were previously  issued and

Opinion") that the purchase of the shares of Series C Preferred Stock and Series
D Preferred  Stock pursuant to the terms to this Agreement is fair and equitable
to the  participants  in the  Plan and the  price  to be paid  for the  Series C
Preferred  Stock and  Series D  Preferred  Stock is not in  excess  of  adequate
consideration.

                       of the Code by  reason  of the  exemptions  set  forth in
                       Section  408(e) of ERISA and Section  4975(d) (13) of the
                       Code;   provided  that  in  making  the   representations
                       contained  in this Section  4(f),  the Trustee has relied
                       upon the  correctness  of the  Company's  representations
                       contained  in  Sections  3(g),  as limited by the proviso
                       therein,  and  3(i)  of  this  Agreement  as  well as the
                       Valuation Opinion;

                g.     the Shares purchased by the Trust have a conversion price
                       which  is  reasonable  as of the date  hereof;  provided,
                       however, that in making the representations  contained in
                       this  Section  4(g),  the  Trustee  has  relied  upon the
                       correctness of the Valuation Opinion; and

                h.     no person or other entity is entitled to any  commissions
                       due to the  Trustee's  actions  in  connection  with  the
                       purchase and sale of the Shares.

         5. The Trustee  hereby (i)  acknowledges  that the Shares  purchased on
behalf of the Trust pursuant to this  Agreement  may, by their terms,  be issued
only to the Trustee or a successor  trustee acting on behalf of the Trust,  (ii)
acknowledges  that  the  Trust  Agreement  provides  that  none of the  Series C
Preferred  Shares and Series D  Preferred  Shares  shall be  transferred  in any
manner to participants under the Plan but in lieu thereof shares of Common Stock
shall be distributed to participants or transferred to the participants' Section
401(k) accounts  pursuant to the terms of the Plan, (iii)  acknowledges that the
Certificate of Designations  provides that any Shares that are transferred  sold
or otherwise disposed of by the Trustee shall be automatically,  and without any
action on the part of the Company,  converted  into shares of Common Stock,  and
(iv) agrees not to transfer,  sell or otherwise  dispose of any of the Shares or
other  shares of Series C  Preferred  Stock and Series D  Preferred  Stock or to
attempt  to do so,  except  in  compliance  with the  Trust  Agreement.  Nothing
contained  in this  Section 5 shall be deemed to  restrict  the  ability  of the
Trustee to convert  shares of Series C  Preferred  Stock and Series D  Preferred
Stock into shares of Common Stock or to require the Company to redeem  shares of
Series C Preferred Stock and Series D Preferred


                                       89


Stock, in each case in accordance with the Certificate of  Designations,  or the
ability  of the  Trustee to  transfer,  sell or  otherwise  dispose of shares of
Common  Stock of the  Company  issued  upon  conversion  of  shares  of Series C
Preferred  Stock and Series D Preferred  Stock or upon a redemption of shares of
Series C Preferred Stock and Series D Preferred Stock.

         6. The Trustee  understands  that the  certificate(s)  representing the
Shares  will bear the  following  legend and that a notation  restricting  their
transfer will be made on the stock transfer books of the Company:

                a.     Series  C:  The  shares  of  Series  C  preferred   stock
                       represented by this  certificate have not been registered
                       under the Securities Act of 1933, as amended. Such shares
                       of stock may not be sold, assigned,  pledged or otherwise
                       transferred  in the absence of an effective  registration
                       statement   under  said   Securities  Act  covering  such
                       transfer  or an opinion of  counsel  satisfactory  to the
                       issuer that registration under said Securities Act is not
                       required.

                       The shares of stock  represented by this  certificate are
                       subject  to  restrictions  on  transfer  set forth in the
                       Certificate of Designations relating to the Corporation's
                       Series C ESOP Convertible  Preferred Stock and in a Stock
                       Purchase  Agreement  dated  as  December  30,  1994.  The
                       Corporation  will furnish a copy of such agreement to the
                       holder of this  certificate  without  charge upon written
                       request.

                b.     Series  D:  The  shares  of  Series  D  preferred   stock
                       represented by this  certificate have not been registered
                       under the Securities Act of 1933, as amended. Such shares
                       of stock may not be sold, assigned,  pledged or otherwise
                       transferred  in the absence of an effective  registration
                       statement   under  said   Securities  Act  covering  such
                       transfer  or an opinion of  counsel  satisfactory  to the
                       issuer that registration under said Securities Act is not
                       required.

                       The shares of stock  represented by this  certificate are
                       subject  to  restrictions  on  transfer  set forth in the
                       Certificate of Designations relating to the Corporation's
                       Series D ESOP Convertible  Preferred Stock and in a Stock
                       Purchase  Agreement  dated  as  December  30,  1994.  The
                       Corporation  will furnish a copy of such agreement to the
                       holder of this  certificate  without  charge upon written
                       request.

         7. Upon the  reasonable  written  request of the  Trustee,  the Company
agrees that, at the Company's expense,  it will prepare and file, as promptly as
practicable  after  such  request,  and use its best  efforts to cause to become


                                       90


effective,  a registration  statement on an appropriate form,  including a final
prospectus  (the  "Registration  Statement"),   under  and  complying  with  the
Securities Act and the rules and regulations thereunder,  relating to the number
of shares of the  Company's  Common Stock into which the Shares are from time to
time convertible or as are acquired upon a redemption or repurchase, including a
redemption  pursuant  to the  provisions  of  Section  7 of the  Certificate  of
Designations,  as shall be necessary,  in the opinion of counsel to the Company,
for the  Trustee  to carry  out its  responsibilities  under  the Plan and Trust
Agreement.  Whenever shares of Common Stock are so registered, the Company shall
also use its best  efforts to  register of qualify  such  shares  covered by the
Registration  Statement  under  the  "blue  sky"  or  securities  laws  of  such
jurisdictions  within the United States as the Trustee may  reasonably  request;
provided,  however,  that the  Company  shall not be  required to consent to the
general service of process for all purposes in any jurisdiction  where it is not
then qualified to do business.

         8. The Company  agrees  that it will use its best  efforts to (i) cause
the Plan to qualify as an employee  stock  ownership  plan within the meaning of
Section 4975(e)(7) of the Code and (ii) maintain such qualification at all times
prior to the termination of the Plan.

         9.     The representations, warranties and agreements in this
Agreement shall survive the date hereof and the Delivery Date.

         10. This  Agreement  shall be governed by and  construed in  accordance
with the laws of the  State of Iowa  applicable  to  contracts  to be  executed,
delivered and  performed in such state,  to the extent not preempted by the laws
of  the  United  States  of  America.   The  parties  hereby   irrevocably   and
unconditionally consent to submit to the exclusive jurisdiction of the courts of
the State of Iowa and the United States of America located in Polk County,  Iowa
for any  actions,  suits  or  proceedings  arising  out of or  relating  to this
Agreement.  This Agreement,  the Plan and Trust Agreement  (including  documents
referred  to  therein  or  delivered  pursuant  thereto)  set forth  the  entire
Agreement of the parties with respect to the subject matter contained herein and
supersede  all prior oral and written  agreements,  if any,  between the parties
with respect to such subject matter.  This Agreement shall bind and inure to the
benefit of all  successors  to, and assigns of, the  parties  hereto;  provided,
however,  that the Trustee  shall not assign or otherwise  transfer its interest
in, or  obligations  under,  this Agreement  without the written  consent of the
Company,  except  that the Trustee may  assign,  without the  Company's  written
consent, all its rights hereunder to any institution  exercising trust powers in
connection with any such institution  assuming the duties of a trustee under the
Trust  Agreement.  In the event that any  provision of this  Agreement  shall be
declared  unenforceable  by a court of competent  jurisdiction,  such  provision
shall be stricken  herefrom  and the  remainder of this  Agreement  shall remain
binding on the


                                       91


parties  hereto.   In  the  event  any  such  provision  shall  be  so  declared
unenforceable  due to its scope or  breadth,  then it shall be  narrowed  to the
scope or breadth permitted by law.

         11.    This Agreement may be executed in two counterparts, each of
which shall be deemed an original, but each of which taken together
shall constitute one and the same instrument.

         12. This Agreement may not be modified with respect to the  obligations
of a party hereto except by an instrument in writing signed by such party.

         13. The terms and  provisions  of the Trust  Agreement  relating to the
nature of the  responsibilities  of the Trustee and the  indemnification  by the
Company of the Trustee are incorporated  herein by reference and made applicable
to this Agreement.

         14.  All  notices,   requests,  or  other  communications  required  or
permitted to be delivered hereunder shall be in writing, delivered to each party
hereto  at its  address  specified  in the  Trust  Agreement  and  shall  become
effective  as  therein  provided.  Any party  hereto  may from time to time,  by
written notice given as aforesaid, designate any other address to which notices,
requests or other communications addressed to it shall be sent.

         IN WITNESS WHEREOF, the parties hereto have duly executed and delivered
this Agreement as of the date first above written.

          Re:  The ALLIED Group Employee Stock Ownership Trust
               -----------------------------------------------

Ladies and Gentlemen:

          We have  acted as  special  counsel  for State  Street  Bank and Trust
Company  ("State  Street"),  as trustee  (the  "Trustee")  of The  ALLIED  Group
Employee Stock Ownership  Trust (the "Trust"),  which forms a part of the ALLIED
Group  Employee Stock  Ownership  Plan  ("Plan"),  and which is evidenced by the
Trust  Agreement  dated  April 16,  1991 (the "ESOP  Trust  Agreement")  between
Trustee and ALLIED Group,  Inc. (the  "Company") in connection with the purchase
by the Trustee of 9,247 shares of Series C ESOP Convertible  Preferred Stock and
_______ shares Series D ESOP Convertible  Preferred Stock of the Company, no par
value (the "Preferred  Stock") pursuant to the Stock Purchase  Agreement between
the Company and the Trustee  dated as of December 30, 1994 (the "Stock  Purchase
Agreement").  Capitalized terms used herein that are not defined herein have the
meanings set forth in the Stock Purchase Agreement.

          In connection therewith,  we have reviewed executed copies of: (i) the
Stock Purchase Agreement;  (ii) the ESOP Trust Agreement;  (iii) the Certificate
of Designations of Series C ESOP  Convertible  Preferred Stock and Series D ESOP
Convertible  Preferred Stock of ALLIED Group,  Inc.; (iv) the corporate  charter
and  by-laws  of State  Street,  both as  amended  to date;  (v) other  records,
documents,  and  instruments  relating to the powers and  organization  of State
Street and to State Street's  acceptance of fiduciary  duties,  obligations  and
trusts;  and (vi)  such  other  certificates  and  documents  as we have  deemed
relevant or necessary as a basis for the opinion expressed below.

          In our examination,  we have assumed without any investigation (i) the
legal capacity of each natural person, (ii) the full power and authority of each
person other than State Street to execute,  deliver and perform its  obligations
under each  document  heretofore  executed  and  delivered  or  hereafter  to be
executed and delivered and to do each other act heretofore  done or hereafter to
be done by such person,  (iii) the due authorization,  execution and delivery by
each person other than

State Street of each document  heretofore executed and delivered by such person,
(iv) the legality, validity, binding effect and enforceability as to each person
other than State Street of each  document  heretofore  executed and delivered or
hereafter to be




                                       93


ALLIED Group, Inc.
December 30, 1994

executed and delivered and of each other act heretofore  done or hereafter to be
done by such person,  (v) the  genuineness of each signature other than those of
officers of State Street and the  completeness and authenticity of each document
submitted  to us as an  original,  (vi) the  conformity  to the original of each
document  submitted to us as a copy,  (vii) the  authenticity of the original of
each document  submitted to us as a copy and (viii) no amendment or modification
hereafter of any provision of any document.  Insofar as our opinion  relates to,
or depends  on, any matter of fact,  we have  relied on  representations  as set
forth  in  the  Stock  Purchase  Agreement,  and  upon  written  statements  and
certificates of officers of State Street and of public officials.

          We are members of the Bar of the  Commonwealth of  Massachusetts  and,
accordingly, we express no opinion herein concerning any law other than the laws
of the Commonwealth of  Massachusetts  and the Federal laws of the United States
of America, to the extent specifically referred to herein.

          As used in this  opinion with  respect to any matter,  the  qualifying
phrase "to the best of our knowledge" means that, without  independent review or
verification,  nothing has come to our attention in the course of our performing
legal services for the
Trustee with respect to said matter.

          We express no opinion as to matters  governed by the Internal  Revenue
Code of 1986 (the "Code") or the Employee Retirement Income Security Act of 1974
("ERISA"), both as amended, or federal or state
securities laws.

          Based on and subject to the foregoing, we are of the opinion that:

          1. State  Street,  acting  solely in its capacity as Trustee,  has all
requisite  power and authority to execute,  deliver and perform its  obligations
under the Stock Purchase Agreement.

          2. The  execution,  delivery  and  performance  of the Stock  Purchase
Agreement  by State  Street,  as  Trustee,  will not  violate the charter or the
by-laws of State Street or, to the best of our knowledge, any order, judgment or
decree binding on State Street (individually or as trustee).

          3.     The Stock Purchase Agreement has been duly executed and
delivered by State Street, as Trustee.

          4. No  authorization,  approval  or  consent  of,  and no  filings  or
registrations  with,  any  governmental  or  regulatory  authority or agency are
necessary  for the  execution,  delivery or  performance  by State Street of the
Stock Purchase Agreement or for the validity or enforceability  thereof,  except
for filings with the Internal  Revenue  Service or the Department of Labor which
may from time to time be required by ERISA or the Code.

December 30, 1994



State Street Bank and Trust Company
Legal Division, Q6N
200 Newport Avenue
North Quincy, MA 02171

Ladies and Gentlemen:

I have acted as legal counsel of ALLIED Group,  Inc., an Iowa  corporation  (the
"Company"),  and in such capacity I have advised the Company in connection  with
The ALLIED Group Employee  Stock  Ownership  Trust (the "ESOP  Trust"),  a trust
established  under that certain Trust Agreement amended and restated as of April
16, 1991 (the "Trust Agreement"),  between the Company and State Street Bank and
Trust Company,  as trustee (the "Trustee" or "State  Street"),  which implements
and forms a part of the ALLIED Group Employee Stock Ownership Plan (the "Plan"),
and in  connection  with the purchase by the Trustee of 9,247 shares of Series C
ESOP Convertible Preferred Stock and _______ shares of Series D ESOP Convertible
Preferred Stock of the Company, no par value (the "Preferred  Stock"),  pursuant
to the Stock  Purchase  Agreement  between the  Company  and the  Trustee  dated
December  30,  1994 (the "Stock  Purchase  Agreement").  Capitalized  terms used
herein without  definition shall have the meanings ascribed to them in the Stock
Purchase Agreement.

In  connection  therewith,  I have  reviewed  executed  copies  of (i) the Stock
Purchase  Agreement,  (ii) the  Certificate  of  Designations  in respect to the
Series C Convertible  Preferred  Stock and Series D Convertible  Preferred Stock
(the  "Certificate  of  Designations"),  and (iii) such other  certificates  and
documents  as I have  deemed  relevant or  necessary  as a basis for the opinion
expressed below.

In such  connection,  I have  assumed the  genuineness  of all  signatures,  the
authenticity  of all documents  submitted to me as originals,  the conformity to
original documents of all documents  submitted to me as photostatic or certified
copies,  and the authenticity of the originals of such copies. I have relied, to
the  extent  I deem  such  reliance  proper,  upon  representations  made in the
documents and certificates or representations made in writing by duly authorized
representatives of the Company.

In  rendering  the  opinions  contained  herein,  I have  assumed that (a) State
Street, as Trustee,  has all requisite power and authority to execute,  deliver,
and perform its  obligations  under the Stock Purchase  Agreement;  (b) that the
execution,  delivery,  and performance of the Stock Purchase  Agreement by State
Street, as Trustee,  will not violate the charter or bylaws of State Street; and
(c) that the Stock  Purchase  Agreement has been executed and delivered by State
Street as Trustee and constitutes the legal,






                                       96


December 30, 1994

valid, and binding obligation of the ESOP Trust,  enforceable in accordance with
its terms,  except as enforcement may be limited by (i) bankruptcy,  insolvency,
reorganization,  or similar laws affecting the enforcement of creditors'  rights
generally, or (ii) equitable principles of general applicability  (regardless of
whether such enforceability is considered in a proceeding in equity or law).

I express no opinion with respect to the laws of any jurisdiction other than the
State of Iowa and the United States of America.  These opinions are expressed as
of the  date  hereof  and are  therefore  subject  to  subsequent  interpretive,
regulatory, legislative, and
judicial developments.

Based on and subject to the foregoing, I am of the opinion that:

          1.     The Company is validly  existing and in good standing under the
                 laws of the State of Iowa and has all requisite corporate power
                 to execute,  deliver, and perform the Stock Purchase Agreement.
                 The  Company  has  taken  all  necessary  corporate  action  to
                 authorize the execution, delivery, and performance of the Stock
                 Purchase Agreement.

          2.     The  Stock  Purchase  Agreement  has  been  duly  executed  and
                 delivered by the Company and is the legal,  valid,  and binding
                 agreement  of the Company,  enforceable  against the Company in
                 accordance   with  its   respective   terms,   except   as  the
                 enforceability  thereof  may  be  limited  by  (i)  bankruptcy,
                 insolvency, reorganization,  moratorium, fraudulent conveyance,
                 or similar laws affecting the enforcement of creditors'  rights
                 generally or (ii) equitable principles of general applicability
                 (regardless of whether such  enforceability  is considered in a
                 proceeding in equity or at law).

          3.     The  Preferred  Shares  have  the  rights,   preferences,   and
                 qualifications  set forth in the  Certificate of  Designations,
                 have been  validly  authorized,  and upon  payment  therefor as
                 provided  in the  Stock  Purchase  Agreement,  will be  validly
                 issued  and  outstanding  and will  constitute  fully-paid  and

                 conversion  of the Preferred  Shares in  accordance  with their
                 terms have been duly and validly  authorized and are sufficient

                 clear  of  any   liens,   claims,   security   interests,   and
                 encumbrances,  except for beneficial interests accruing to Plan
                 participants and their beneficiaries.

          5.     As of the date hereof, the Plan and the ESOP Trust in form meet
                 in all material  respects (a) the  applicable  requirements  of
                 Section 401(a) of the Internal Revenue Code of 1986, as amended
                 (the "Code"),  (b) the  requirements  applicable to an employee
                 stock ownership plan for purposes of Section  4975(e)(7) of the
                 Code and the regulations  promulgated  thereunder,  and (c) the
                 requirements for exemption from tax under Section 501(a) of the
                 Code.

          6.     The shares of Preferred Stock to be purchased by the ESOP Trust
                 constitute "employer  securities" within the meaning of Section
                 409(1) of the Code and "qualifying  employer securities" within
                 the meaning of Section 407(d)(5) of ERISA.

          7.     The shares of Preferred Stock to be purchased by the ESOP Trust
                 have voting  rights  equivalent  to the common stock into which
                 such  shares  may be  converted,  and the Plan meets the voting
                 rights  requirements  of  Section  409(e)(2)  of the Code  with
                 respect to such shares.

          In rendering the foregoing  opinions and any other opinions  expressed
in this letter, I have relied on the following assumptions:

                  a.    Except as to matters  expressly  opined on  herein,  the
                        Plan and ESOP Trust have been,  and will continue to be,
                        administered  and  operated  at all  times  strictly  in
                        accordance with their terms and with all requirements of
                        applicable law including, but not limited to, all of the
                        requirements   applicable  to  a  qualified  plan  under
                        Section  401(a);  the  requirements   applicable  to  an
                        "employee  stock  ownership plan" (within the meaning of
                        Section  4975(e)(7))  under  Section 4975 and 409 of the
                        Code; and the  requirements  applicable to a tax- exempt
                        trust under Section  501(a);  and with the provisions of
                        ERISA and all regulations thereunder.

                 b.     The  conversion  price at which the shares of  Preferred
                        Stock may be converted to common stock of the Company is
                        reasonable  as  of  the  date  of  acquisition  of  such
                        Preferred Stock by the ESOP Trust.

                 c.     No fiduciary of the Plan has received any  consideration
                        of the type  described in Section  4975(c)(1)(F)  of the
                        Code and Section  406(b)(3) of ERISA in connection  with
                        the transactions described herein.



                                       98

                 d.     The  fiduciaries  of the Plan and the  ESOP  Trust  have
                        acted  prudently  and in  good  faith,  and  have  given
                        appropriate    consideration    to   those   facts   and
                        circumstances  that are relevant to the  transactions in
                        accordance with the fiduciary requirements of part 4
                        of Title I of ERISA.

In connection  with the  assumptions  made in paragraph (b) above,  I understand
that the Trustee has received an opinion from Whitman  Heffernan  and Rhein Co.,
Inc.  to  effect  that (i) the  price to be paid by the ESOP  Trust per share of
Preferred Stock is not in excess of fair market value or adequate consideration,
as defined under Title I of the Employee Retirement Income Security Act of 1974,
as amended,  including the regulations thereunder ("ERISA");  and (ii) the terms
and conditions of the proposed  transaction,  including the terms  governing the
right to convert the Preferred Stock into Common Stock of the Company,  are fair
and reasonable to the ESOP Trust from a financial point of view.

These  opinions  are  rendered  solely to the  Trustee  in  connection  with the
transactions  of the Trustee  contemplated by the Stock Purchase  Agreement.  No
other person,  firm, or corporation may rely upon these opinions for any purpose
without my prior written consent.

Yours very truly,
