     The Company represents and warrants to the Buyer, that, except as 
specifically disclosed in a letter of the Company delivered to the Buyer

     2.1.  Incorporation, Capitalization, Etc.  The Company has been duly 
incorporated, is validly existing as a corporation in good standing under the 
laws of the State of Delaware and is duly qualified to do business as a

preferred stock have ever been issued or authorized to be issued. All 
outstanding shares of Common Stock have been duly authorized and validly

accordance with this Agreement the Shares will be duly authorized, validly

performance by the Company of this Agreement and the Stockholder Agreement 
and the consummation of the transactions contemplated hereby and thereby have 
been duly authorized by all required action on the part of the Company and 
its stockholders, and each of this Agreement and the Stockholder Agreement 
has been duly executed and delivered by the Company and constitutes a valid 
and binding obligation of the Company, enforceable against the Company in 
accordance with its terms, subject to bankruptcy, insolvency, fraudulent 
transfer, reorganization, moratorium and other similar laws of general 
applicability relating, to or affecting creditors' rights and to general 
equity principles. The execution and delivery by the Company of this 
Agreement and the Stockholder Agreement and the consummation of the 
transactions contemplated hereby and thereby do not and will not conflict 
with or result in a breach or violation of or default under any law, rule or 
regulation, the certificate of incorporation or by-laws of the Company or the 
corresponding documents of any of the Subsidiaries, any judgement, decree, 
order, license or permit issued by any governmental or regulatory body, board

therein or necessary to make the statements made therein, in the light of the 
circumstances under which they were made, not misleading. True and complete 
copies of all Reports filed since January 1, 1995 have been furnished by the 
Company to the Buyer. The financial statements contained or incorporated by 
reference in the Reports fairly present the financial position, results of 
operations and changes in financial position to which they relate as at the 
dates and for the periods covered thereby (subject, in the case of unaudited 
interim statements, to normal year-end audit adjustments) in each case in 
accordance with generally accepted accounting principles consistently applied 
during the periods involved, except as otherwise stated therein. The Company 
and its Subsidiaries have timely filed all required reports, registrations 
and statements, together with any amendments thereto, with the SEC, THE OTS,

Insurance Corporation, any state banking commission or other regulatory 
authority, the National Association of Securities Dealers, Inc. and any other 
self-regulatory organization.

    2.5. No Material Adverse Change. Except as otherwise disclosed in the

change in the financial condition, results of operations, properties, assets,

applications and registrations with, all federal, state, local and foreign 
governmental or regulatory bodies that are required in order to permit it to 
carry on its business as presently conducted, and all such material permits, 
licenses, authorizations, orders and approvals are in full force and effect, 
except in each case where the failure to do so or to have done so would not 
have a material adverse effect on the Company or any of its Subsidiaries. 
Neither the Company nor any of its Subsidiaries is a party to any cease and 
desist order, written agreement or memorandum of understanding with, or a 
party to any commitment letter or similar undertaking to, or is subject to 
any order or directive by, or is a recipient of any extraordinary supervisory 
letter from, federal or state governmental authorities charged with the 
supervision or regulation of depository institutions or depository 
institution holding companies or engaged in the insurance of bank and/or 
savings and loan deposits, nor has it been advised by any such authorities 
that they are contemplating issuing or requesting (or are considering the 
appropriateness of issuing or requesting) any such order, directive, written 
agreement, memorandum of understanding, extraordinary supervisory letter, 
commitment letter or similar undertaking.

XIII and XIV of the Company's restated certificate of incorporation do not 
and will not apply to this Agreement or the Stockholder Agreement or the 
transactions contemplated hereby or thereby, in the case of Article XIII, 
because the time provision applicable to that article has expired, and in the 
case of Article XIV, because the transactions contemplated thereby have 
received all of the required approvals stated therein.

    WHEREAS, concurrently with the execution and delivery hereof, Deltec has 
purchased 111,563 2/3 shares (the "Shares") of original common stock, par 
value $0.01 per share (the "Common Stock") of the Company, pursuant to the 
Stock Purchase Agreement, dated as of December 31, 1996 (the "Stock Purchase 
Agreement"), between the Company and Deltec;

    WHEREAS, as of the date hereof, the Company has the authority to issue 
5,000,000 shares of the par value $0.01 per share, of which 4,500,000 shares 
are common stock and 500,000 shares are serial preferred stock, and the 
Company's authorized common stock consists of 3,020,000 shares designated as 
original common stock, 340,000 shares designated as Class B common stock, 
340,000 shares designated as Class C common stock and 800,000 shares 
designated as Class D common stock, of which 446,254 2/3 shares of Common 
Stock have been issued (after giving effect to Deltec's purchase of the 
Shares) and no shares of Class B common stock, Class C common stock or Class 
D common stock have ever been issued or authorized to be issued, and no 
shares of serial preferred stock have ever been issued or authorized to be 
issued; and

    WHEREAS, by entering into this Agreement and the Stock Purchase 
Agreement, the Company, Deltec and the Controlling Stockholder understand 
that Deltec's acquisition of the Shares is solely for Deltec's own account 
for the purpose of investment and for the purpose of owning up to, but not 
more than, 25% of the outstanding voting stock of the Company and with no 
purchase or effect of controlling or exercising a controlling influence over 
the management or policies of the Company;

    NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements set forth herein and for other good and valuable 
consideration, the receipt and sufficiency of which is hereby acknowledged, 
and in order to induce Deltec to purchase the Shares as contemplated by the 
Stock Purchase Agreement, the parties hereto hereby agree as follows:




                                  ARTICLE I

                              BOARD OF DIRECTORS

    1.1 Directors. So long as this Agreement shall continue in effect and 
so long as Deltec shall own at least 15% of the outstanding Common Stock of 
the Company, Deltec shall have the right to nominate one director to serve on 
the Board of Directors of the Company, and so long as Deltec shall remain in 
compliance with Section 1.2 of this Agreement, the Controlling Stockholder 
shall vote (or cause to be voted) all shares of Common Stock owned by him for 
the election as a director of the Company of the nominee designated by Deltec 
at any annual or special meeting called for such purpose.

    1.2 Rebuttal Agreement. While this Agreement continues in effect, 
Deltec shall remain in compliance with the Rebuttal Agreement between Deltec 
and the Office of Thrift Supervision.

                                       
                                  ARTICLE II

                       SALE OR PURCHASE OF CAPITAL STOCK

      2.1 Issuance of Capital Stock. If the Company shall at any time propose 
to issue or sell any additional shares of its Common Stock (the "Additional 
Shares"), whether such shares are authorized but previously unissued shares 
or are treasury shares, then the Company shall notify Deltec thereof as 
promptly as practicable and shall offer to sell to Deltec, concurrently with 
the issuance and sale of the Additional Shares, such number of additional 
shares of Common Stock (including fractional shares) so that Deltec shall 
continue, after giving effect to such sales, to own exactly 25% of the 
outstanding shares of Common Stock. In case such sale of Additional Shares is 
for cash, the Company's offer to Deltec shall be at a purchase price equal to 
the price per share paid for the Additional Shares and shall be upon 
substantially the same other terms and conditions, except that in the case of 
the exercise of employee stock options, the Company's offer to Deltec shall 
be at a price equal to the Market Price (as hereinafter defined) on the date 
of sale. In case such sale of Additional Shares is for consideration other 
than cash, the Company's offer to Deltec shall be a price equal to the fair 
market value per share of such other consideration, as determined by the 
Board of Directors of the Company for purposes of the Company's financial 
statements. "Market Price" as of any date shall mean the average of the high 
and low sale prices of the Company's Common Stock as reported on the NASDAQ 
Stock Market (the "Average") for the 30 business days immediately preceding 
the date in question, provided that (i) prior to the issuance of stock 
pursuant to a public offering (the "Public Offering") expected to occur prior 
to June 30, 1997, or such later date as the Company and its underwriters may 
determine, the Market Price shall equal 94.7% of the book value of the 
Company as set forth on the Company's most recent balance sheet prior to the 
date in question, (ii) the Market Price of stock purchased in connection with 
the Public

                                     2


Offering shall equal the public offering price, (iii) during the 30-day 
period following the Public Offering the Market Price will equal the greater 
of the public offering price or the Average for the period from the date of 
the Public Offering to the date in question, and (iv) the Market Price of 
stock purchased in connection with any subsequent public offering shall equal 
the public offering price in such subsequent public offering.

    2.2 Purchase or Acquisition of Common Stock. If at any time the Company 
shall propose to purchase or otherwise acquire any outstanding shares of its 
Common Stock, then the Company shall notify Deltec thereof as promptly as 
practicable and shall offer to purchase from Deltec, concurrently with such 
purchase or other acquisition, such number of shares (including fractional 
shares) that, after giving effect thereto, Deltec will own exactly 25% of the 
outstanding shares of Common Stock.

    2.3 Other Classes of Stock. If at any time the Company shall propose to 
issue or sell any shares of Class B common stock, Class C common stock, Class 
D common stock or serial preferred stock authorized by its certificate of 
incorporation or any other class of common stock hereafter authorized by the 
Company, then the Company shall notify Deltec thereof as promptly as 
practicable and shall offer to sell to Deltec, concurrently with the issuance 
of such shares such number of such shares as will enable Deltec to maintain 
ownership of 25% of such other class of stock.

    2.4 Registration Rights. The Company hereby grants Deltec the following 
rights with respect to registration under the Securities Act of 1933 (the 
"Securities Act") of any shares of Common Stock or other equity securities 
(hereinafter referred to as the "Registrable Securities") acquired by Deltec 
from the Company under the Stock Purchase Agreement or this Agreement. If 
Deltec desires to sell any Registrable Securities at any time after the 
earlier of the completion of the Public Offering or June 30, 1997, Deltec 
shall give the Company at least 30 days' notice thereof, specifying the 
approximate number of Registrable Securities Deltec desires to sell and the 
intended method of disposition thereof, and if the opinion of Deltec or the 
Company such intended method of disposition requires registration under the 
Securities Act, the Company will promptly prepare and file a Registration 
Statement under the Securities Act covering the Registrable Securities and 
will use its best efforts to cause such Registration Statement to become 
effective as promptly as practicable. If at any time after the completion of 
the Public Offering the Company shall propose to file a Registration 
Statement under the Securities Act, the Company shall give Deltec at least 10 
days' notice thereof and shall afford Deltec the opportunity to include any 
Registrable Securities it proposes to sell in such Registration Statement. In 
connection with any such Registration Statement, the Company shall indemnify 
and hold harmless Deltec and any underwriter or placement agent of such 
Registrable Securities (each an "Underwriter") against any losses, claims, 
damages or liabilities, joint or several, or actions in respect thereof 
("Claims"), to which Deltec or such Underwriter may become subject, under the 
Securities Act or otherwise, insofar as such Claims arise out of or are based 
upon any untrue statement or alleged untrue statement of any material fact 
contained in the Registration Statement, the related prospectus, any 
preliminary prospectus or any 

                                       3


amendment or supplement thereto (collectively, "Registration Documents") or 
the omission or alleged omission to state in any Registration Document a 
material fact required to be stated therein or necessary to make the 
statements made therein not misleading, and will reimburse Deltec or any such 
Underwriter for any legal or other expenses reasonably incurred in 
investigating or defending any such Claim as such expenses are incurred; 
provided, that the Company shall not be liable in any such case to the extent 
that any such Claim arises out of or is based upon an untrue statement or 
alleged untrue statement or omission or alleged omission made in any 
Registration Document in reliance upon and in conformity with written 
information furnished to the Company by or on behalf of Deltec or any such 
Underwriter specifically for use in such Registration Document.  In 
connection with any such Registration Statement, Deltec shall indemnify and 
hold harmless the Company and any Underwriter against any Claims to which the 
Company or such Underwriter may become subject, under the Securities Act or 
otherwise, insofar as such Claims arise out of or are based upon any untrue 
statement or alleged untrue statement of any material fact contained in 
written information furnished to the Company by or on behalf of Deltec 
specifically for use therein, and will reimburse the Company or any such 
Underwriter for any legal or other expenses reasonably incurred in 
investigating or defending any such Claim as such expenses are incurred.  In 
connection with only the first two Registration Statements filed by the 
Company pursuant to the second sentence of this Section 2.4 and all 
Registration Statements filed by the Company pursuant to the third sentence 
of this Section 2.4, the Company shall be responsible for all expenses and 
fees incident to the preparation of such Registration Statement, including 
all registration and filing fees, the cost of preparing and printing the 
Registration Documents and any other documents used in connection with the 
offering, purchase, sale and delivery of the Registrable Securities, the 
costs and charges of any transfer agent, registrar, custodian or 
attorneys-in-fact and the fees and disbursements of counsel for the Company 
and the Company's independent public accountants, including the expenses of 
any "comfort" letters; provided that Deltec shall be responsible for the 
fees and disbursements of its own counsel, if any, and all underwriting 
discounts and commissions relating to the sale or disposition of the 
Registrable Securities.
                                       
                                 ARTICLE III

                   [Letterhead of Muldoon, Murphy & Faucette]


                                                             [December 31, 1996]



The Deltec Banking Corporation Limited
Deltec House, P.O. Box N-3229
Lyford Cay, Nassau, Bahamas

Ladies and Gentlemen:

             We have acted as counsel for Argo Bancorp, Inc., a Delaware 
corporation (the "Company"), in connection with the Stock Purchase Agreement, 
dated as of [December 30, 1996] (the "Stock Purchase Agreement"), between the 
Company and The Deltec Banking Corporation Limited, a Bahamas banking 
corporation (the "Buyer"), and the Stockholder Agreement among the Company, 
the Buyer and John G. Yedinak, dated as of December [31], 1996 (the 
"Stockholder Agreement"). Unless otherwise defined herein, capitalized terms 
used herein have the respective meanings ascribed to them in the Stock 
Purchase Agreement. We have examined the Stock Purchase Agreement and such 
corporate records, certificates and other documents, and such questions of 
law, as we have considered necessary or appropriate for the purposes of this 
opinion. Upon the basis of such examination, it is our opinion that:

             1.  The Company has been duly incorporated and is validly existing
       as a corporation in good standing under the laws of the State of 
       Delaware. The Company is duly registered as a savings and loan holding 
       company with the Office of Thrift Supervision under Section 10 of the 
       Home Owners' Loan Act, as amended. The Company has all requisite power 
       and authority to enter into the Stock Purchase Agreement and the 
       Stockholder Agreement and to perform its respective obligations 
       thereunder.

             2.  The Company has the authority to issue 5,000,000 shares of the
       par value $0.01 per share, of which 4,500,000 shares are common stock and
       500,000 shares are serial preferred stock. The Company's authorized 
       common stock consists of 3,020,000 shares designated as original common 
       stock (herein, the "Common Stock"), 340,000 shares designated as Class B
       common stock, 340,000 shares designated as Class C common stock and 
       800,000 shares designated as Class D common stock, of which 334,691 
       shares designated as original common stock have been issued prior to the
       date hereof. All outstanding shares of Common Stock have been duly 
       authorized and validly




The Deltec Banking Corporation Limited                                        2


       issued and are fully paid and nonassessable, and the Shares issued to 
       the Buyer have been duly authorized and validly issued and are fully 
       paid and nonassessable.

             3.  The execution, delivery and performance by the Company of 
       the Stock Purchase Agreement and the Stockholder Agreement and the 
       consummation of the transactions completed thereby have been duly 
       authorized by all required action on the part of the Company and its 
       stockholders, and each of the Stock Purchase Agreement and the 
       Stockholder Agreement has been duly executed and delivered by the 
       Company and constitutes a valid and binding obligation of the Company, 
       enforceable against the Company in accordance with its terms, subject to
       bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium 
       and other similar laws of general applicability relating to or affecting
       creditors' rights and to general equity principles. The execution and 
       delivery by the Company of the Stock Purchase Agreement and the 
       Stockholder Agreement and the consummation of the transactions 
       contemplated thereby do not and will not conflict with or result in a 
       breach or violation of or default under any law, rule or regulation, the
       certificate of incorporation or by-laws of the Company, any judgment, 
       decree, order, license or permit, known to us, issued by any governmental
       or regulatory body, board or agency, or any agreement, indenture or 
       instrument, known to us, to which the Company is a party or is otherwise
       subject.

             4.  The provisions of Articles XIII and XIV of the Company's 
       restated certificate of incorporation do not and will not apply to the 
       Stock Purchase Agreement or the Stockholder Agreement or the 
       transactions contemplated thereby, in the case of Article XIII, 
       because the time provision applicable to that article has expired, and 
       in the case of Article XIV, because the transactions contemplated 
       thereby have received all of the approvals required by that article.

              In rendering the foregoing opinion, we have relied as to certain 
matters upon information obtained from public officials, officers of the 
Company and other sources believed by us to be responsible, and we have 
assumed that the signatures on all documents examined by us are genuine, 
assumptions which we have not independently verified.

                                                 Very truly yours,
