                               JANUARY 4, 1996 

Dear Stockholder: 

   On September 25, 1995, United Counties Bancorporation ("UCB") mailed to 
you a Notice of Special Meeting and Proxy Statement/Prospectus ("Proxy 
Statement/Prospectus") relating to the Special Meeting of Stockholders of UCB 
(the "Special Meeting") initially convened on Wednesday, November 1, 1995 at 
10:00 a.m. at the corporate headquarters of UCB, Four Commerce Drive, 
Cranford, New Jersey 07016. The Special Meeting was adjourned until further 
notice in order to permit UCB stockholders to receive and consider the 
information contained in the accompanying Proxy Statement/Prospectus 
Supplement (the "Supplement") and the Special Meeting will now be held, in 
accordance with the enclosed Notice of Meeting, at 10:00 a.m., Wednesday, 
February 7, 1996 at the corporate headquarters of UCB. 

   As described in the Proxy Statement/Prospectus, another copy of which has 
been included with this Supplement for your convenience, at the reconvened 
Special Meeting you will be asked to consider and vote upon a proposal to 
approve and adopt an Agreement and Plan of Merger, dated as of May 23, 1995 
(the "Merger Agreement"), by and between Meridian Bancorp, Inc. ("Meridian") 
and UCB, pursuant to which UCB will merge (the "Merger") with and into 
Meridian, with Meridian surviving the Merger and each share of common stock, 
no par value, $1.00 stated value per share, of UCB ("UCB Common Stock") at 
the closing of the Merger will be converted into 5.00 shares of common stock, 
par value $5.00 per share, of Meridian ("Meridian Common Stock"). 

   After the mailing of the Proxy Statement/Prospectus, Meridian and 
CoreStates Financial Corp, a bank holding company with its principal offices 
located in Philadelphia, Pennsylvania ("CoreStates"), entered into an 
Agreement and Plan of Merger, dated as of October 10, 1995 (the 
"Meridian/CoreStates Merger Agreement"), pursuant to which Meridian will 
merge with and into CoreStates (the "Meridian/CoreStates Merger"), with 
CoreStates being the surviving corporation. The Meridian/CoreStates Merger 
Agreement provides that upon completion of the Meridian/CoreStates Merger, 
each share of Meridian Common Stock will be exchanged for 1.225 shares of 
common stock, par value $1.00 per share, of CoreStates ("CoreStates Common 
Stock"), subject to increase under certain limited circumstances but not 
subject to decrease. Accordingly, if the Merger is completed, each share of 
UCB Common Stock ultimately will be converted into 6.125 shares of CoreStates 
Common Stock, assuming the Meridian/CoreStates Merger is also completed, 
subject to increase under certain limited circumstances but not subject to 
decrease. 

   Because of the pendency of the Meridian/CoreStates Merger, UCB postponed 
the stockholder vote on the Merger Agreement in order to furnish you with 
information regarding the proposed Meridian/CoreStates Merger. The enclosed 
Supplement provides you with such information. 

   As described in the Proxy Statement/Prospectus, completion of the Merger 
is subject to certain conditions, including the approval of the Merger 
Agreement by UCB's stockholders and by various regulatory agencies. Subject 
to the foregoing conditions, the Merger currently is expected to close early 
in the first quarter of 1996, but there can be no assurance that such 
conditions will be met or, if met, as to the timing of the closing of the 
Merger. 

   As described in this Supplement, the Meridian/CoreStates Merger is subject 
to certain conditions, including the approval of the Meridian/CoreStates 
Merger Agreement by the shareholders of both Meridian and CoreStates and 
various regulatory agencies, including the Board of Governors of the Federal 
Reserve System. Subject to the foregoing conditions, the Meridian/CoreStates 
Merger currently is expected to close in the second quarter of 1996, but 
there can be no assurance as to whether such conditions will be met or, if 
met, as to the timing of the closing. 

   UCB's Board of Directors has considered the Meridian/CoreStates Merger, 
confirmed its approval of the Merger and determined that the Merger remains 
in the best interests of the stockholders of UCB. The Board accordingly 
confirms its recommendation that you vote for APPROVAL of the Merger 
Agreement. 

   This Supplement describes the Meridian/CoreStates Merger and provides 
information which may be important to your vote at the Special Meeting. 
Please review this material carefully. The Supplement should be read in 
conjunction with the Proxy Statement/Prospectus mailed to you on or about 
September 25, 1995, a copy of which has been included with the Supplement for 
your convenience.

   IF YOU HAVE NOT YET SIGNED AND RETURNED THE PROXY CARD ENCLOSED WITH THE 
PROXY STATEMENT/PROSPECTUS DATED SEPTEMBER 25, 1995, OR IF YOU WISH TO REVOKE 
SUCH PROXY AND CHANGE YOUR VOTE, I URGE YOU TO EXECUTE, DATE, AND RETURN THE 
ENCLOSED BLUE PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE AS SOON AS 
POSSIBLE TO ENSURE THAT YOUR SHARES WILL BE VOTED AT THE SPECIAL MEETING. YOU 
NEED NOT EXECUTE THE ENCLOSED BLUE PROXY CARD IF YOU PREVIOUSLY HAVE 
EXECUTED, DATED, AND RETURNED A PROXY CARD AND YOU DO NOT WISH TO CHANGE YOUR 
VOTE. YOU SHOULD NOT SEND IN CERTIFICATES FOR YOUR SHARES OF UCB COMMON STOCK 
AT THIS TIME. 
    
   
   
As of November 1, 1995, the date the Special Meeting was originally 
convened, UCB had received proxies from holders representing 91.7% of the 
outstanding shares of UCB Common Stock and 91.4% of the outstanding shares 
had been voted in favor of the Merger Agreement. Unless a substantial number 
of such proxies are revoked, the management of UCB expects the Merger 
Agreement to be approved at the Special Meeting, although there can be no 
assurance that stockholders will not revoke their proxies. 

   It is very important for your shares to be represented at the Special 
Meeting, regardless of whether you plan to attend in person and whether or 
not you have previously executed and returned the proxy card enclosed with 
the Proxy Statement/Prospectus dated September 25, 1995. The affirmative vote 
of at least 66 2/3 % of the outstanding shares of UCB Common Stock is 
required to approve the Merger Agreement. Therefore, a failure to vote will 
have the same effect as a vote against the Merger Agreement. 

   On behalf of the UCB Board of Directors, I thank you for your support and 
patience in light of the delay resulting from the proposed 
Meridian/CoreStates Merger, and urge you to vote for approval of the Merger 
Agreement. 






                                Sincerely yours, 

            
                                /s/  Eugene H. Bauer

                         READING, PENNSYLVANIA 19601 

   This Proxy Statement/Prospectus Supplement (the "Supplement") is being 
furnished by United Counties Bancorporation, a New Jersey corporation 
("UCB"), to the holders of UCB common stock, no par value, $1.00 stated value 
per share ("UCB Common Stock"), in connection with the solicitation of 
proxies by UCB's Board of Directors for use at a Special Meeting of 
Stockholders of UCB initially convened on Wednesday, November 1, 1995, at 
Four Commerce Drive, Cranford, New Jersey 07016 (the "Special Meeting"), and 
at any adjournment or adjournments thereof. The Special Meeting was adjourned 
until further notice as a result of events subsequent to the mailing of the 
Proxy Statement/Prospectus to permit stockholders of UCB to receive and 
consider the information contained herein. The Special Meeting will be 
reconvened at 10:00 a.m., Wednesday, February 7, 1996, at the corporate 
headquarters of UCB, Four Commerce Drive, Cranford, New Jersey. If there are 
not sufficient shares represented for a quorum or votes to approve the Merger 
Agreement at the Special Meeting, the Special Meeting may be further 
adjourned to permit further solicitation. This Supplement is a supplement to 
and should be read in conjunction with the accompanying Proxy 
Statement/Prospectus dated September 25, 1995, which was initially mailed to 
UCB stockholders on or about September 25, 1995. Any statement contained in 
that Proxy Statement/Prospectus will be deemed to be modified or superseded 
to the extent that a statement set forth herein, or in a document 
subsequently filed under the Securities Exchange Act of 1934 and incorporated 
by reference herein, modifies or supersedes such statement but, except as so 
modified or superseded, all statements contained therein shall remain in full 
force and effect as if fully set forth herein. 

   This Supplement and the accompanying form of Proxy are first being mailed 
to the stockholders of record of UCB on or about January 5, 1996. 

   The purpose of the Special Meeting is to consider and vote upon a proposal 
to approve the Agreement and Plan of Merger, dated as of May 23, 1995 (the 
"Merger Agreement"), between UCB and Meridian Bancorp, Inc. ("Meridian"), 
pursuant to which UCB will merge with and into Meridian (the "Merger"), 
subject to the terms and conditions contained therein. See "SUMMARY" and "THE 
MERGER AGREEMENT" in the accompanying Proxy Statement/Prospectus, and a copy 
of the Merger Agreement which is attached as ANNEX A to the accompanying 
Proxy Statement/Prospectus. 

   Upon completion of the Merger each outstanding share of UCB Common Stock 
will be converted into and represent the right to receive 5.00 shares (the 
"Exchange Ratio") of Meridian's common stock, $5.00 par value per share 
("Meridian Common Stock"). Pursuant to the terms of the Merger Agreement, 
cash will be paid in lieu of fractional shares of Meridian Common Stock. For 
a more complete description of the Merger Agreement and the terms of the 
Merger, see "THE MERGER" in the accompanying Proxy Statement/Prospectus. 

   Subsequent to mailing the Proxy Statement/Prospectus, Meridian and 
CoreStates Financial Corp ("CoreStates") entered into an Agreement and Plan 
of Merger, dated as of October 10, 1995 (the "Meridian/CoreStates Merger 
Agreement"), which provides for the merger (the "Meridian/CoreStates Merger") 
of Meridian into CoreStates, with CoreStates the surviving corporation in the 
Meridian/CoreStates Merger. The Meridian/CoreStates Merger Agreement provides 
that upon completion of the Meridian/CoreStates Merger, each share of 
Meridian Common Stock will be exchanged for 1.225 shares of common stock, par 
value $1.00 per share, of CoreStates ("CoreStates Common Stock"), subject to 
possible increase under certain limited circumstances but not subject to 
decrease. Accordingly, if the Merger is completed, each share of UCB Common 
Stock ultimately will be converted into 6.125 shares of CoreStates Common 
Stock, assuming the Meridian/CoreStates Merger is also completed. The 
Meridian/CoreStates Merger is subject to certain conditions, including the 
approval of the Meridian/CoreStates Merger Agreement by the shareholders of 
both Meridian and CoreStates and various regulatory agencies. 

   Meridian Common Stock is traded on the NASDAQ Stock Market under the 
symbol "MRDN." On January 3, 1996, the closing price of Meridian Common Stock 
was $46.875 per share. UCB Common Stock is listed on the NASDAQ Small-Cap 
Market under the symbol "UCTC." On January 3, 1996, the last reported sale 
price of UCB Common Stock on the NASDAQ Small-Cap Market was $230.50 per 
share. CoreStates Common Stock is listed on the New York Stock Exchange under 
the symbol "CFL." On January 3, 1996, the last reported sale price of 

<PAGE>
CoreStates Common Stock was $38.25 per share. See "UPDATED MARKET PRICES" 
herein. UCB stockholders are urged to obtain current market quotations for 
Meridian Common Stock, UCB Common Stock and CoreStates Common Stock. UCB 
stockholders are not assured of receiving any specific market value of 
Meridian Common Stock or CoreStates Common Stock. The price of Meridian 
Common Stock at the effective date of the Merger may be higher or lower than 
the market price at the time of entering into the Merger Agreement, at the 
time of mailing this Supplement or at the time the Special Meeting is 
reconvened. Similarly, the price of CoreStates Common Stock at the effective 
date of the Meridian/CoreStates Merger may be higher or lower than the market 
price at the time Meridian and CoreStates entered into the 
Meridian/CoreStates Merger Agreement, at the time of mailing this Supplement 
or at the time the Special Meeting is reconvened or on the dates of the 
meetings of CoreStates and Meridian shareholders at which those shareholders 
will vote on the Meridian/CoreStates Merger. 

   Meridian has filed a Registration Statement pursuant to the Securities Act 
of 1933, as amended (the "Securities Act"), covering the shares of Meridian 
Common Stock which will be issued in connection with the Merger. In addition 
to constituting the UCB Proxy Statement for the Special Meeting, the 
accompanying Proxy Statement/Prospectus, as amended and supplemented by this 
Supplement, constitutes a Prospectus of Meridian with respect to the Meridian 
Common Stock to be issued if the Merger is consummated. 

   THE SHARES OF MERIDIAN COMMON STOCK OFFERED HEREBY HAVE NOT BEEN APPROVED 
OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE 
SECURITIES COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY 
STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS 
PROXY STATEMENT/PROSPECTUS SUPPLEMENT. ANY REPRESENTATION TO THE CONTRARY IS 
A CRIMINAL OFFENSE. 

   THE SHARES OF MERIDIAN COMMON STOCK OFFERED HEREBY ARE NOT SAVINGS 
ACCOUNTS, DEPOSITS OR OTHER OBLIGATIONS OF A BANK OR SAVINGS ASSOCIATION AND 
ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER 
GOVERNMENTAL AGENCY.

MERIDIAN/CORESTATES MERGER AGREEMENT 

   
   On October 10, 1995, Meridian entered into the Meridian/CoreStates Merger 
Agreement with CoreStates, which provides for the Meridian/CoreStates Merger. 
Upon completion of the Meridian/CoreStates Merger, among other things, each 
outstanding share of Meridian Common Stock will be converted into and 
exchanged for 1.225 shares of CoreStates Common Stock, subject to possible 
increase under certain limited circum- stances but not subject to decrease. 
See "CERTAIN INFORMATION REGARDING PENDING MERIDIAN/CORESTATES MERGER -- 
Termination; Possible Exchange Ratio Increase." 

   Under applicable law, the Meridian/CoreStates Merger requires distribution 
to UCB stockholders of the information contained herein for their 
consideration in connection with their vote regarding the Merger Agreement. 
As a result, UCB adjourned until further notice the Special Meeting from its 
originally scheduled date of November 1, 1995 and by means of this Supplement 
has notified shareholders of record as of the record date that the adjourned 
meeting will be reconvened at 10:00 a.m. on February 7, 1996. Assuming (i) 
UCB stockholders approve the Merger Agreement at the Special Meeting, (ii) 
the Merger is completed and (iii) the Merger is completed prior to the 
completion of the Meridian/CoreStates Merger, each outstanding share of UCB 
Common Stock will be converted into and exchangeable for 5.00 shares of 
Meridian Common Stock. 

   In addition, assuming completion of the Meridian/CoreStates Merger, each 
outstanding share of Meridian Common Stock (including each share of Meridian 
Common Stock that will have been issued to UCB stockholders pursuant to the 
Merger, assuming the Meridian/CoreStates Merger is completed subsequent to 
completion of the Merger) will be converted into and exchanged for 1.225 
shares of CoreStates Common Stock, subject to possible increase under certain 
limited circumstances but not subject to decrease (the "Meridian/CoreStates 
Exchange Ratio"), pursuant to the terms of the Meridian/CoreStates Merger 
Agreement. See "CERTAIN INFORMATION REGARDING PENDING MERIDIAN/CORESTATES 
MERGER -- Termination; Possible Exchange Ratio Increase." If both the Merger 
and the Meridian/CoreStates Merger are completed, each share of UCB Common 
Stock ultimately would be converted into 6.125 shares of CoreStates Common 
Stock (the product of the Exchange Ratio and the Meridian/CoreStates Exchange 
Ratio) except that cash will be paid in lieu of fractional shares of 
CoreStates Common Stock, subject to possible increase under certain limited 
circumstances but not subject to decrease. 

   Meridian has set ____________, 1996 as the date for a special meeting of 
shareholders at which the holders of Meridian Common Stock are to vote on the 
Meridian/CoreStates Merger Agreement and has established December 26, 1995 as 
the record date for its shareholders entitled to vote at such meeting. 
ACCORDINGLY, THE MERGER WILL NOT BE COMPLETED IN TIME FOR UCB STOCKHOLDERS TO 
BECOME MERIDIAN SHAREHOLDERS AND HAVE AN OPPORTUNITY TO VOTE AS MERIDIAN 
SHAREHOLDERS ON THE MERIDIAN/CORESTATES MERGER. 
    

   AT THE SPECIAL MEETING UCB STOCKHOLDERS WILL BE VOTING ON THE MERGER, AND 
THERE IS NO ASSURANCE THAT THE MERIDIAN/CORESTATES MERGER WILL BE COMPLETED. 
IF UCB STOCKHOLDERS VOTE TO APPROVE THE MERGER, SUCH STOCKHOLDERS MUST BE 
WILLING TO ACCEPT THEIR OWNERSHIP INTEREST IN MERIDIAN WITHOUT REGARD TO 
WHETHER THE MERIDIAN/CORESTATES MERGER IS CONSUMMATED. SEE "UNAUDITED PRO 
FORMA CONDENSED COMBINED FINANCIAL INFORMATION" HEREIN. 

   
   Subject to the conditions described in "CERTAIN INFORMATION REGARDING 
PENDING MERIDIAN/CORESTATES MERGER -- Conditions to Completion of the 
Meridian/CoreStates Merger" below and the accompanying Proxy 
Statement/Prospectus under "THE MERGER -- Conditions to the Merger," the 
Merger presently is expected to close early in the first quarter of 1996 and 
the Meridian/CoreStates Merger presently is expected to close in the second 
quarter of 1996.

(1) The market value for Meridian Common Stock, UCB Common Stock and 
    CoreStates Common Stock represents the last reported sale prices per 
    share on May 23, 1995, the last business day preceding public 
    announcement of the Merger and January 3, 1996, the latest practicable 
    date prior to the mailing of this Supplement. 
    

(2) The pro forma equivalent per share market value of UCB Common Stock at 
    each specified date was determined by multiplying the last reported sale 
    price of a share of Meridian Common Stock on such date by the Exchange 
    Ratio of 5.00 shares of Meridian Common Stock for each share of UCB 
    Common Stock outstanding. 

   
(3) The pro forma equivalent per share market value of UCB Common Stock at 
    each specified date was determined by multiplying the last reported sale 
    price of CoreStates Common Stock on such date by 6.125 (the product of 
    the Exchange Ratio of 5.00 shares of Meridian Common Stock for each share 
    of UCB Common Stock outstanding and the Meridian/CoreStates Exchange 
    Ratio of 1.225 shares of CoreStates Common Stock for each share of 
    Meridian Common Stock). The Meridian/CoreStates Exchange Ratio is subject 
    to possible increase under certain limited circumstances but is not 
    subject to decrease. See "CERTAIN INFORMATION REGARDING PENDING 
    MERIDIAN/CORESTATES MERGER -- Termination; Possible Exchange Ratio 
    Increase." 
    

   Stockholders are advised to obtain current market quotations for Meridian 
Common Stock. No assurance can be given as to the market price of Meridian 
Common Stock on or after the Effective Date of the Merger. Stockholders are 
also advised to obtain current market quotations for CoreStates Common Stock. 
No assurance can be given as to the market price of CoreStates Common Stock at 
             
                                      5 

<PAGE>

the effective date of the Meridian/CoreStates Merger (assuming the 
Meridian/CoreStates Merger is completed). It is expected that the market 
price of Core- States Common Stock will fluctuate between the date of this 
Proxy Statement/Prospectus Supplement and the date on which the 
Meridian/CoreStates Merger is completed (assuming the Meridian/CoreStates 
Merger is completed) and thereafter. UCB stockholders should understand that 
at the Special Meeting the stockholders are voting on the Merger, and that 
there is no assurance that the Meridian/CoreStates Merger will be completed. 
If UCB stockholders vote to approve the Merger, such stockholders must be 
willing to accept their ownership interest in Meridian without regard to 
whether the Meridian/CoreStates Merger is completed. See "UNAUDITED PRO FORMA 
CONDENSED COMBINED FINANCIAL INFORMATION" herein. 

                  UPDATED COMPARATIVE PER COMMON SHARE DATA 

   
   The following table sets forth certain unaudited comparative per share 
data relating to book value per common share, cash dividends declared per 
common share, net income per common share and net income per common share 
excluding significant items (i) on an historical basis for Meridian, 
CoreStates and UCB, (ii) on a pro forma basis to reflect completion of the 
Merger, (iii) on a pro forma basis to reflect completion of the 
Meridian/CoreStates Merger, (iv) on an equivalent pro forma basis per share 
of UCB Common Stock to reflect completion of the Merger, and (v) on an 
equivalent pro forma basis per share of UCB Common Stock to reflect 
completion of the Meridian/CoreStates Merger. The following equivalent per 
share data assume the Exchange Ratio of 5.00 shares of Meridian Common Stock 
for each share of UCB Common Stock outstanding for the Merger and an exchange 
ratio of 1.225 shares of CoreStates Common Stock for each share of Meridian 
Common Stock for the Meridian/CoreStates Merger. 

   Meridian expects to achieve certain operating cost savings and revenue 
enhancements as a result of the Merger and similarly CoreStates expects to 
achieve operating cost savings as a result of the Meridian/CoreStates Merger. 
Such cost savings and revenue enhancements are not reflected in the 
historical pro forma information set forth in this Supplement. See "THE 
MERGER -- Management and Operations After the Merger" in the accompanying 
Proxy Statement/Prospectus and "CERTAIN INFORMATION REGARDING PENDING 
MERIDIAN/CORESTATES MERGER -- Consolidation of Operations; Anticipated Cost 
Savings" herein. This information should be read in conjunction with the 
consolidated financial statements of Meridian, CoreStates, UCB, including the 
notes thereto, incorporated by reference in this Supplement and accompanying 
Proxy Statement/Prospectus and the other financial data appearing elsewhere

- ------ 
(1) Pro forma dividends per share for Meridian and UCB represent historical 
    dividends paid by Meridian. UCB pro forma equivalent dividends per share 
    (Meridian and UCB) represent such amounts multiplied by 5.00. Based on 
    Meridian's current quarterly dividend of $.37 per share, equivalent pro 
    forma quarterly cash dividends per share of UCB Common Stock (Meridian 
    and UCB) would be $1.85 per share as a result of the Merger, an increase 
    of 131.25% from the $.80 normal quarterly dividend paid by UCB for the 
    quarter immediately prior to execution of the Merger Agreement. See 
    "UPDATED MARKET PRICES," herein and "DESCRIPTION OF MERIDIAN -- Market 
    Price of and Dividends on Meridian Common Stock"; "THE MERGER -- Terms of 
    the Merger -- Management and Operations After the Merger; Post-Merger 
    Dividend Policy" in the accompanying Proxy Statement/Prospectus.

   
    Pro forma dividends per share for Meridian, CoreStates and UCB represent 
    historical dividends paid by CoreStates. UCB pro forma equivalent 
    dividends per share (Meridian, CoreStates and UCB) represent such amounts 
    multiplied by 6.125). Based on CoreStates' current quarterly dividend of 
    $.42 per share, equivalent pro forma quarterly cash dividends per share 
    of UCB Common Stock would be $2.5725 per share as a result of the Merger 
    and the Meridian/CoreStates Merger, an increase of 221.6% from the $.80 
    normal quarterly dividend paid by UCB for the quarter immediately prior 
    to execution of the Merger Agreement. See "UPDATED MARKET PRICES," 
    herein. 

(2) Based on income before cumulative effect of a change in accounting 
    principle. 

    The computation of earnings per share does not include the effect of (i) 
    Meridian Common Stock which may be issued in connection with Meridian's 
    Floating Rate Subordinated Capital Notes (the "Notes"), (ii) a 

                                      7

    repurchase of up to one million shares of Meridian Common Stock 
    authorized by Meridian, provided such repurchase does not adversely 
    affect the ability of Meridian to account for the Merger as a pooling of 
    interests or (iii) any repurchase of CoreStates Common Stock by 
    CoreStates. See "DESCRIPTION OF MERIDIAN CAPITAL SECURITIES -- Capital 
    Notes" in the accompanying Proxy Statement/Prospectus. 
    Meridian's historical earnings per share are based on weighted average 
    fully diluted shares outstanding. CoreStates and UCB historical earnings 
    per share and all pro forma earnings per share are based on weighted 
    average common shares outstanding. 
    

(3) Pro forma net income per common share for Meridian and UCB represents 
    historical net income for Meridian and UCB combined on the assumption 
    that Meridian and UCB had been combined for each period presented on a 
    pooling of interests basis, divided by the number of shares of Meridian 
    Common Stock which will be issued and outstanding after the Merger. UCB 
    equivalent pro forma net income per common share (Meridian and UCB) 
    represents such amounts multiplied by 5.00. 

   
(4) Pro forma net income per common share for Meridian, CoreStates and UCB 
    represents historical net income for CoreStates, Meridian and UCB 
    combined on the assumption that CoreStates, Meridian and UCB had been 
    combined for each period presented on a pooling of interests basis, 
    divided by the number of shares of CoreStates Common Stock which will be 
    issued and outstanding after both the Merger and the Meridian/CoreStates 
    Merger. UCB equivalent pro forma net income per common share (Meridian, 
    CoreStates and UCB) represents such amounts multiplied by 6.125. 

(5) The following significant non-recurring items are excluded from net 
    income per share for the nine-month periods ended September 30, 1995 and 
    1994 and for the years ended December 31, 1994 and 1993:

                   UPDATE OF REQUIRED REGULATORY APPROVALS 

   The Merger is subject to approval by the Board of Governors of the Federal 
Reserve System (the "Federal Reserve") under Sections 3 and 4 of the Bank 
Holding Company Act of 1956 (the "BHCA"), but the Federal Reserve's 
regulations permit such approval requirement to be waived and for the Federal 
Deposit Insurance Corporation (the "FDIC") to undertake the approval process 
in connection with its review under the Bank Merger Act. The Federal Reserve 
granted Meridian's waiver request by letter dated September 15, 1995. 

   The FDIC approved the merger of United Counties Trust Company into 
Meridian Bank, New Jersey (the "Bank Merger") under the Bank Merger Act by 
order dated November 2, 1995. The FDIC approval order expires if the Bank 
Merger is not completed by June 2, 1996. 

   
   The New Jersey Department of Banking has not yet approved the Bank Merger. 
    

   The Meridian/CoreStates Merger is also subject to various regulatory 
approvals. See "CERTAIN INFORMATION REGARDING PENDING MERIDIAN/CORESTATES 
MERGER -- Regulatory Approvals Required." 

                 MERIDIAN SELECTED HISTORICAL FINANCIAL DATA 

   
   The following table sets forth certain selected historical consolidated 
summary financial data for Meridian. This data is derived from, and should be 
read in conjunction with, the consolidated financial statements of Meridian, 
including the notes thereto, and management's discussions and analysis of 
financial conditions and results of operations incorporated by reference in 
this Supplement and the accompanying Proxy Statement/Prospectus. See 
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and "AVAILABLE 
INFORMATION." The data for the years ended December 31, 1994 through December 
31, 1990 are derived from Meridian's consolidated financial statements, which 
have been audited. Interim unaudited data for the nine months ended September 
30, 1995 and 1994 reflect, in the opinion of management of Meridian, all 
adjustments (consisting of normal recurring adjustments) necessary for a fair 
presentation of such data. During the second quarter of 1995, Meridian 
recorded a restructuring charge of $32.0 million ($20.8 million after tax). 
The restructuring charge related to the implementation of a program intended 
to reduce Meridian's performance ratio (non-interest expense as a percentage 
of income) from its current level to 59.9% or lower by the end of the first 
quarter of 1996. The following historical financial data at and for the nine 
month period ended September 30, 1995 reflect this restructuring charge. 
Results for the nine months ended September 30, 1995 are not necessarily 
indicative of results which may be expected for any other interim period or 
for the year as a whole.

(1) Meridian's provision for loan losses on loans in 1990 included an 
    addition of $75 million to its provision in the third quarter of that 
    year made in response to weakening of the economy and the real estate 
    sector in particular and to the changing banking climate. 

(2) In June 1995, Meridian completed an internal review of its operations and 
    businesses and announced a company-wide plan designed to improve its 
    operating performance and competitive position. As a result of this 
    review, Meridian recorded a restructuring charge in the second quarter of 
    1995 of $32.0 million ($20.8 million after-tax or $0.37 per share). 
    Implementation of the plan began at the end of the second quarter of 1995 
    and will continue over approximately the next twelve months from that 
    date. At the end of that period, the process is expected to reduce net 
    operating expenses on an annualized pre-tax basis by $55 million, while 
    providing recurring revenue enhancements of $13 million, increasing 
    Meridian's net income on an annual basis by $0.78 per share. 

(3) Return on average total assets and return on average total shareholders' 
    equity are calculated based on income before cumulative effect of a 
    change in accounting principle, and where applicable, on income from 
    continuing operations, net of income taxes. The interim data is 
    calculated on an annualized basis for purposes of comparability with full 
    year data. 

(4) Cash dividends declared per share for the respective periods prior to 
    Meridian's acquisition of Commonwealth Bancshares Corporation (on August 
    31, 1993) and UCB assume that Meridian would have declared cash dividends 
    per share equal to the cash dividends per share actually declared by 
    Meridian. 

    Meridian's historical cash dividends declared per share for the year 
    ended December 31, 1992, reflect a new dividend payment schedule adopted 
    in the first quarter of 1992. Dividends paid in 1992 aggregated $1.20 per 
    share.

   The following table sets forth certain selected historical consolidated 
financial data for UCB. This data is derived from, and should be read in 
conjunction with, the consolidated financial statements of UCB, including the 
notes thereto, incorporated by reference into this Supplement and the 
accompanying Proxy Statement/Prospectus. See "INCORPORATION OF CERTAIN 
DOCUMENTS BY REFERENCE" and "AVAILABLE INFORMATION." The data for the years 
ended December 31, 1994 through December 31, 1990 are derived from UCB's

opinion of the management of UCB, all adjustments (consisting of normal 
recurring adjustments) necessary for a fair presentation of such data. 
Results for the nine months ended September 30, 1995 are not necessarily 
indicative of results which may be expected for any other interim period or

              SELECTED PRO FORMA COMBINED FINANCIAL INFORMATION 

   The following sets forth selected unaudited pro forma financial data 
reflecting the Merger and the Meridian/CoreStates Merger (each accounted for 
using the pooling of interests method of accounting). The pro forma financial 
information does not necessarily reflect what the actual results of Meridian 
or CoreStates would be following completion of the Merger or the 
Meridian/CoreStates Merger. 

   
   The pro forma information has been prepared based upon a fixed exchange 
ratio of 5.00 shares of Meridian Common Stock for each share of UCB Common 
Stock outstanding with respect to the Merger. See "THE MERGER -- Terms of the 
Merger" in the accompanying Proxy Statement/Prospectus. The pro forma 
information also has been prepared assuming that options to purchase 47,601 
shares of UCB Common Stock are converted into options to purchase or 
exercised for 238,005 shares of Meridian Common Stock as required by the 
Merger Agreement. The pro forma information also assumes a fixed exchange 
ratio of 1.225 shares of CoreStates Common Stock for each share of Meridian 
Common Stock outstanding with respect to Meridian/CoreStates Merger. The 
Meridian/CoreStates Exchange Ratio is subject to possible increase under 
certain limited circumstances but is not subject to decrease. See "CERTAIN 
INFORMATION REGARDING PENDING MERIDIAN/CORESTATES MERGER -- Termination; 
Possible Exchange Ratio Increase" herein. 
    

   Meridian expects to realize certain revenue enhancements and to achieve 
certain cost savings through the consolidation of certain back office and 
support functions and through elimination of redundant costs after the Merger 
and CoreStates also expects to achieve operating costs savings as a result of 
the Meridian/CoreStates Merger. No assurance can be given that any such cost 
savings or revenue enhancements will be realized. The pro forma information 
does not reflect any of these anticipated cost savings or revenue 
enhancements. See "THE MERGER -- Management and Operations After the Merger" 
in the accompanying Proxy Statement/Prospectus and "CERTAIN INFORMATION 
REGARDING PENDING MERIDIAN/CORESTATES MERGER -- Consolidation of Operations; 
Anticipated Cost Savings" herein.

    30, 1995 after giving effect to the cancellation of 381 thousand shares 
    of UCB Common Stock held as treasury stock. 

   
(4) Effective January 1, 1995, Meridian adopted Statement of Financial 
    Accounting Standards No. 114, "Accounting by Creditors for Impairment of 
    a Loan". Prior period financial information has been restated to reflect 
    the reclassification of in-substance foreclosed loans to non-performing 
    loans and writedowns against in-substance foreclosed loans from 
    non-interest expenses to the provision for possible loan losses.
 
    In-substance foreclosed loans for UCB are immaterial.
 
    CoreStates prospectively adopted FAS 114 on January 1, 1995, and as 
    foreclosed loans are immaterial to CoreStates, prior period financial 
    information was not restated.

    As permitted under pooling of interests accounting, the pro forma 
    financial information is presented as if CoreStates reclassified 
    in-substance foreclosed loans to loans, and writedowns against 
    in-substance foreclosed loans from non-interest expenses to the provision 
    for possible loan losses for all periods presented. 
    

(5) Loans held for sale in CoreStates' historical financial information have 
    not exceeded the requirements for separate balance sheet disclosure and 
    accordingly have been included in total loans. Meridian's historical 
    financial information reflects loans held for sale as a separate caption 
    on the balance sheet (or in other assets in a condensed balance sheet). 
    In the pro forma financial information, combined loans held for sale do 
    not exceed the requirements for separate balance sheet disclosure and 
    therefore Meridian's loans held for sale have been reclassified to total 
    loans. 

   
(6) Based on a preliminary review of Meridian's loan portfolio, CoreStates 
    has decided to take a different approach to the workout of certain 
    assets. In CoreStates' general experience, a strategy that involves the 
    accelerated resolution of problem assets has been more economical than a 
    long-term work out approach. It has been CoreStates' general experience 
    that the costs of working out assets as well as other carrying costs 
    typically outweigh any improvement in those assets' realized value. 
    CoreStates currently estimates that in connection with the change in 
    strategic direction and to conform Meridian's consumer lending charge-off 
    policies to those of CoreStates, CoreStates will take an addition to the 
    allowance for possible loan losses of approximately $50 million to $80 
    million and, accordingly, has adjusted September 30, 1995 pro forma 
    shareholders' equity by $70.0 million, $45.5 million after-tax, the 
    current estimate based on the preliminary review. CoreStates currently 
    estimates that the assets related to $66 million of the $70 million 
    estimated provision will be disposed of within eighteen months of 
    completion of the Meridian/CoreStates Merger. The carrying value of these 
    assets is approximately $225 million and the estimated provision 
    represents 29% of this amount. It is also estimated that the conforming 
    adjustments, mostly related to consumer lending charge-off policies, will 
    comprise approximately $4 million of the $70 million estimated provision.
     
    Pro forma shareholders' equity at September 30, 1995 also reflects 
    charges of approximately $105.0 million, which include: $40.0 million for 
    employee severance costs; $24.1 million for the costs of consolidating 
    and closing branches and other duplicate facilities; and $40.9 million 
    for other expenses directly attributable to CoreStates' pending 
    acquisition of Meridian. Accordingly, pro forma shareholders' equity at 
    September 30, 1995 has been reduced by $75.1 million, the after-tax 
    effect of the charges and expenses directly attributable to CoreStates' 
    pending acquisition of Meridian. The aggregate cash outflow related to 
    these charges is expected to be approximately $80 million.

    Deferred taxes receivable at statutory rates totalling $54.4 million 
    related to the approximately $105.0 million of expenses directly 
    attributable to CoreStates' pending acquisition of Meridian and the $70.0 
    million addition to Meridian's allowance for possible loan losses are 
    reflected in other assets. 

(7) Reflects the pro forma adoption by Meridian of the FAS 106 transitional 
    liability of $28.8 million, $18.7 million after-tax, effective January 1, 
    1992. See footnote 4 on page 24. 
    

(8) Reflects the conversion of 68.563 million pro forma shares of Meridian 
    Common Stock into 83.990 million shares of CoreStates Common Stock on 
    September 30, 1995 after giving effect to the cancellation of 515 
    thousand shares of Meridian Common Stock held as treasury stock.

        FOOTNOTES TO PRO FORMA CONDENSED COMBINED STATEMENTS OF INCOME 
                                 (UNAUDITED) 

   
(1) The Pro Forma Condensed Combined Statements of Income do not reflect the 
    estimated $16.0 million of charges and expenses directly attributable to 
    the Merger since these charges are non-recurring. See footnote 2 on page 
    16. The Pro Forma Condensed Combined Statements of Income also do not 
    reflect the estimated $70.0 million provision for possible loan losses 
    related to Meridian's loan portfolio, or charges and expenses of 
    approximately $105.0 million directly attributable to CoreStates pending 
    acquisition of Meridian, since these charges are non-recurring. Were 
    these expenses reflected in the Pro Forma Condensed Combined Statement of 
    Income for the nine months ended September 30, 1995, net income would 
    decrease by $135.1 million, or $0.61 per share. 
    

(2) Reflects the elimination of intercompany interest on Federal funds 
    transactions between CoreStates and UCB. 

(3) Includes gain on exchange of securities available for sale of $12 million 
    pre-tax and $7.6 million after-tax. 

   
(4) Reflects the adoption of FAS 106, "Employers Accounting for 
    Postretirement Benefits Other Than Pensions." Meridian adopted FAS 106 on 
    January 1, 1993, the date required under that statement. As permitted by 
    FAS 106, Meridian elected not to recognize immediately its $28.8 million 
    transitional liability, but to amortize that liability over 20 years. 

    UCB adopted FAS 106 effective January 1, 1992 and elected to recognize 
    immediately the transitional liability of $6.2 million, $4.0 million 
    after-tax, as the cumulative effect of a change in accounting principle. 

    As permitted under FAS 106, CoreStates elected to recognize immediately 
    the January 1, 1992 transitional liability of $128.7 million pre-tax, 
    $84.9 million after-tax, as the cumulative effect of a change in 
    accounting principle in the first quarter of 1992. 

    As permitted under pooling of interests accounting, the pro forma 
    financial information is prepared as if Meridian adopted FAS 106 
    effective January 1, 1992 and immediately recognized the $28.8 million, 
    $18.7 million after-tax, transitional liability. Pro forma salaries, 
    wages and benefits have been adjusted accordingly. 
    

(5) CoreStates, Meridian, UCB and pro forma earnings per common share for the 
    nine months ended September 30, 1995 and 1994 and for the years ended 
    December 31, 1994, 1993 and 1992 were based on weighted average common 
    shares outstanding as dilution from potentially dilutive common stock 
    equivalents was less than 3% for each period. 

(6) Meridian adopted FAS 112, "Employers' Accounting for Postemployment 
    Benefits" on January 1, 1994, the date required under the statement. The 
    adoption of FAS 112 resulted in a charge of $4.2 million, $2.7 million 
    after-tax, in the first quarter of 1994. As permitted under pooling of 
    interests accounting, the pro forma information is prepared as if 
    Meridian adopted FAS 112 effective January 1, 1993. 

    The impact of FAS 112 on UCB is immaterial. 

    Effective January 1, 1993, CoreStates adopted FAS 112. CoreStates 
    recognized the January 1, 1993 FAS 112 transitional liability of $20.0 
    million, $13.0 million after-tax as the cumulative effect of a change in 
    accounting principle. 

(7) In June 1995, Meridian completed an internal review of its operations and 
    businesses and announced a company-wide plan designed to improve its 
    operating performance and competitive position. As a result of this 
    review Meridian recorded a restructuring charge in the second quarter of 
    1995 of $32.0 million ($20.8 million after-tax or $0.37 per share). 

    In March 1995, CoreStates completed an intensive review of its operations 
    and businesses and announced a corporate-wide process redesign plan, 
    which restructures its banking services around customers and enhances 
    employees' authority to make decisions to benefit customers. As a result 
    of this process redesign, CoreStates recorded a $110 million pre-tax 
    restructuring charge, $70.0 million after-tax or $0.49 per share, 

                                      24 

<PAGE>
    in March 1995. CoreStates recorded restructuring credits of $3.0 million, 
    $1.9 million after-tax or $0.01 per share in the second quarter of 1995 
    and $2.4 million, $1.5 million after-tax or $0.01 per share in the third 
    quarter of 1995, related to gains on the curtailment of future pension 
    benefits associated with employees terminated during the second and third 
    quarters. 

   
 (8) Cash dividends declared per share for the respective periods prior to 
     Meridian's acquisition of Commonwealth Bancshares Corporation (on August 
     31, 1993) and UCB assume that Meridian would have declared cash 
     dividends per share equal to the cash dividends declared per share 
     actually declared by Meridian. 

     Cash dividends declared per share for the respective periods prior to 
     CoreStates' acquisition of First Peoples Corporation (on September 3, 
     1992), Constellation Bancorp (on March 16, 1994), Independence Bancorp, 
     Inc. (on June 27, 1994) and Meridian assume that CoreStates would have 
     declared cash dividends per share equal to the cash dividends per share 
     actually declared by CoreStates. 

 (9) Meridian and UCB elected to prospectively adopt FAS 109 on January 1, 
     1993 and recognize a cumulative benefit/(expense) of $7.2 million and 
     $(579) thousand, respectively, as the cumulative effect of a change in 
     accounting principle. CoreStates retroactively adopted FAS 109 in the 
     first quarter of 1992. As permitted under pooling of interests 
     accounting, the pro forma financial information is prepared as if 
     Meridian and UCB also retroactively adopted FAS 109 effective January 1, 
     1987. 

(10) In connection with the adoption of FAS 114, Meridian's historical 
     Condensed Combined Statements of Income reflect the reclassification of 
     writedowns against in-substance foreclosed loans from non-interest 
     expenses to the provision for possible loan losses. As in-substance 
     foreclosed loans are immaterial to Core- States, CoreStates' historical 
     financial information reflects the charges associated with writedowns 
     against in substance foreclosed loans in other non-interest expenses. As 
     permitted under pooling of interests accounting, the pro forma financial 
     information is presented as if CoreStates reclassified writedowns 
     against in substance foreclosed loans from other non-interest expenses 
     to the provision for possible loan losses. 

     In-substance foreclosed loans for UCB are immaterial.

                  UPDATED OPINION OF UCB'S FINANCIAL ADVISOR 

   On May 23, 1995, Goldman, Sachs & Co. ("Goldman Sachs") delivered its 
written opinion to the Board of Directors of UCB that as of the date of such 
opinion, the Exchange Ratio pursuant to the Merger Agreement was fair to the 
holders of shares of UCB Common Stock. Goldman Sachs subsequently confirmed 
its earlier opinion by delivery of its written opinion dated as of September 
21, 1995 and its written opinion dated as of January 4, 1996. 

   The full text of the written opinion of Goldman Sachs dated as of January 
3, 1996, which sets forth assumptions made, matters considered and 
limitations on the review undertaken in connection with the opinion, is 
attached hereto as Annex A to this Supplement and is incorporated herein by 
reference. Stockholders of UCB are urged to, and should, read such opinion in 
its entirety. In connection with the delivery of its written opinion dated as 
of January 4, 1996, Goldman Sachs reviewed the analyses referred to in the 
accompanying Proxy Statement/Prospectus (a summary of which is set forth in 
the accompanying Proxy Statement/Prospectus, see "THE MERGER -- Opinion of 
Financial Advisor") and updated such analyses to the extent they considered 
appropriate and also reviewed certain financial information relating to 
CoreStates and the Meridian/CoreStates Merger, as set forth in the Goldman 
Sachs opinion dated as of January 4, 1996. In addition, Goldman Sachs 
confirmed with the managements of UCB, Meridian and CoreStates the absence of 
any material change to the information previously reviewed. 

   Pursuant to a letter agreement dated July 27, 1994 and executed by UCB on 
August 5, 1994 (the "Engagement Letter"), UCB has agreed to pay Goldman Sachs 
a transaction fee upon consummation of the Merger based on the value of the 
consideration received by UCB stockholders. As a result of the increase in 
the value of Meridian Common Stock following execution of the 
Meridian/CoreStates Merger Agreement, UCB will pay Goldman Sachs a 
transaction fee of approximately $3.2 million. 

   As indicated in the Proxy Statement/Prospectus, Goldman Sachs regularly 
provides investment banking and financial advisory services to Meridian. In 
that regard, Goldman Sachs has been engaged to provide Meridian certain 
financial advisory services in connection with the Meridian/Corestates 
Merger. Meridian has paid Goldman Sachs a fee of $3.3 million for providing 
such services. In addition, Meridian has paid Goldman Sachs a fee of $250,000 
for work relating to preparation of a strategic alternatives study and 
presentation of such study to Meridian's Board of Directors in September 
1995. Meridian has agreed to reimburse Goldman Sachs for its reasonable 
out-of-pocket expenses, including attorneys' fees, and to indemnify Goldman 
Sachs against certain liabilities, including certain liabilities under the 
federal securities laws, in connection with these engagements. 
    

                    CERTAIN INFORMATION REGARDING PENDING 
                          MERIDIAN/CORESTATES MERGER 

   
   The following summary of the pending Meridian/CoreStates Merger is 
included to provide certain information regarding that transaction should it 
be completed. Information provided regarding the Meridian/CoreStates Merger 
will apply to UCB stockholders only if both the Merger and the 
Meridian/CoreStates Merger are completed. This summary is necessarily 
incomplete and is qualified in its entirety by reference to the more detailed 
information, including a copy of the Meridian/CoreStates Merger Agreement and 
historical financial information regarding CoreStates, contained in 
Meridian's Current Reports on Form 8-K dated October 10, 1995 and December 
28, 1995 (which are incorporated herein by reference). 

CORESTATES FINANCIAL CORP 

   CoreStates is a bank holding company incorporated under the laws of the 
Commonwealth of Pennsylvania. CoreStates' principal bank subsidiaries are 
CoreStates Bank, N.A., a national banking association headquartered in 
Philadelphia, Pennsylvania; New Jersey National Bank, a national banking 
association headquartered in Ewing Township, New Jersey; and CoreStates Bank 
of Delaware, N.A., a national banking association with its sole office in New 
Castle County, Delaware (collectively, the "CoreStates Banking 
Subsidiaries"). Through the CoreStates Banking Subsidiaries, CoreStates is 
engaged in the business of providing wholesale banking services, Consumer 
Financial Services, including retail banking, trust and investment management 
services, and electronic payment services. As of September 30, 1995, 
CoreStates had, on a consolidated basis, approximately $28.85 bil-

                                      27 
    

<PAGE>
   
lion in assets, $20.69 billion in deposits and $2.32 billion in shareholders' 
equity. CoreStates was the 31st largest bank holding company in the United 
States measured by total assets at September 30, 1995; after giving effect to 
the Meridian/CoreStates Merger, CoreStates believes it would have been the 
21st largest in the United States as of that date. 
    

STRUCTURE OF THE MERIDIAN/CORESTATES MERGER 

   
   Subject to the terms and conditions of the Meridian/CoreStates Merger 
Agreement and in accordance with Pennsylvania law, at the effective time of 
the Meridian/CoreStates Merger (the "Meridian/CoreStates Effective Time"), 
Meridian will merge with and into CoreStates. CoreStates will be the 
continuing corporation in the Meridian/CoreStates Merger, and will continue 
its corporate existence under Pennsylvania law under the name "CoreStates 
Financial Corp." At the Meridian/CoreStates Effective Time, the separate 
corporate existence of Meridian will terminate. The Articles of Incorporation 
and Bylaws of CoreStates, as in effect immediately prior to the 
Meridian/CoreStates Effective Time, will continue unchanged after the 
Meridian/CoreStates Effective Time. 
    

EFFECT OF MERIDIAN/CORESTATES MERGER ON UCB AND UCB STOCKHOLDERS 

   
   Upon completion of the Meridian/CoreStates Merger, except as described 
below, each outstanding share of Meridian Common Stock, other than certain 
shares held in Meridian's treasury or held by CoreStates or any wholly-owned 
subsidiary of CoreStates or Meridian, will be automatically converted into 
1.225 fully paid and nonassessable shares of CoreStates Common Stock (except 
that cash will be paid in lieu of fractional shares), subject to possible 
increase in certain limited circumstances but not subject to decrease. See 
"-- Termination; Possible Exchange Ratio Increase" below. Accordingly, if 
both the Merger and the Meridian/CoreStates Merger are completed, each share 
of UCB Common Stock ultimately would be converted into 6.125 shares of 
CoreStates Common Stock (the product of the Exchange Ratio and the 
Meridian/CoreStates Exchange Ratio), except that cash will be paid in lieu of 
fractional shares of Meridian Common Stock. 

   Meridian and UCB presently expect that the Merger, if approved by UCB's 
stockholders at the Special Meeting, will close early in the first quarter of 
1996, although there can be no assurance that all conditions to the Merger 
will be met or as to the timing of such conditions being met and, 
accordingly, there can be no assurance as to the timing or occurrence of the 
Merger. See "THE MERGER -- Conditions to the Merger" in the accompanying 
Proxy Statement/Prospectus. As of November 1, 1995, the date the Special 
Meeting was originally convened, UCB had received proxies from holders 
representing 91.7% of the outstanding shares of UCB Common Stock and 91.4% of 
the outstanding shares had been voted in favor of the Merger Agreement. 
Unless a substantial number of such proxies are revoked, the management of 
UCB expects the Merger Agreement to be approved at the Special Meeting, 
although there can be no assurance that shareholders will not revoke their 
proxies. 
    

   The Meridian/CoreStates Merger is subject to the conditions described 
below under "Conditions to Completion of the Meridian/CoreStates Merger." The 
Meridian/CoreStates Merger presently is expected to close in the second 
quarter of 1996, but there can be no assurance that all conditions to the 
Meridian/CoreStates Merger will be met or as to the timing of such conditions 
being met and, accordingly, there can be no assurance as to the timing or 
occurrence of the Meridian/CoreStates Merger. 

   
   Meridian has set ____________, 1996 as the date for a special meeting of 
shareholders at which the holders of Meridian Common Stock are to vote on the 
Meridian/CoreStates Merger Agreement and has established December 26, 1995 as 
the record date for its shareholders entitled to vote at such meeting. 
ACCORDINGLY, THE MERGER WILL NOT BE COMPLETED IN TIME FOR UCB STOCKHOLDERS TO 
BECOME MERIDIAN SHAREHOLDERS AND HAVE AN OPPORTUNITY TO VOTE AS MERIDIAN 
SHAREHOLDERS ON THE MERIDIAN/CORESTATES MERGER. 

   The Meridian/CoreStates Exchange Ratio was determined through arm's-length 
negotiations between Core- States and Meridian. The Meridian/CoreStates 
Exchange Ratio is subject to increase in certain limited circumstances but is 
not subject to decrease. See "-- Termination; Possible Exchange Ratio 
Increase." 

                                      28 
    

<PAGE>
   
   On a pro forma basis after giving effect to the Meridian/CoreStates Merger 
(and after giving effect to the Merger), the percentage of total assets, 
shareholders' equity, net interest income and net income of CoreStates at and 
for the three months ended September 30, 1995 contributed by Meridian would 
have been 36.0%, 40.0%, 31.2% and 31.7%, respectively. 
    

MERIDIAN AND CORESTATES STOCK OPTION AGREEMENTS 

   
   In conjunction with the execution and delivery of the Meridian/CoreStates 
Merger Agreement, Meridian and CoreStates entered into stock option 
agreements, dated as of October 10, 1995 (in each case, a "Stock Option 
Agreement"), pursuant to which Meridian and CoreStates granted to each other 
options to purchase up to 19.9% of the outstanding Meridian Common Stock, in 
the case of CoreStates, and up to 19.9% of the outstanding Core- States 
Common Stock, in the case of Meridian. The Stock Option Agreements will 
become exercisable upon the occurrence of certain events as set forth in the 
respective Stock Option Agreements and will be exercisable at a per share 
price of $38.50, in the case of Meridian Common Stock, and $38.8125, in the 
case of CoreStates Common Stock. The number of shares subject to such options 
and the purchase price per share provided for therein are subject to 
adjustment as provided in the respective Stock Option Agreements. Meridian 
and Core- States approved and entered into the respective Stock Option 
Agreements to induce each other to enter into the Meridian/CoreStates Merger 
Agreement. The Stock Option Agreements are intended to increase the 
likelihood that the Meridian/CoreStates Merger will be completed in 
accordance with its terms. Consequently, certain aspects of the Stock Option 
Agreements may have the effect of discouraging persons who might now or prior 
to the completion of the Meridian/CoreStates Merger be interested in 
acquiring all of or a significant interest in Meridian or CoreStates from 
considering or proposing such an acquisition, even if, in the case of 
Meridian, such persons were prepared to offer to pay consideration to 
Meridian shareholders which had a higher current market price than the shares 
of CoreStates Common Stock to be received per share of Meridian Common Stock 
pursuant to the Meridian/CoreStates Merger Agreement. 
    

REQUIRED SHAREHOLDER VOTE 

   
   Meridian. Shareholders of Meridian entitled to cast at least 66-2/3% of 
the votes which all shareholders are entitled to cast on the record date (the 
"Meridian Record Date," which has been established as the close of business 
on December 26, 1995) must be represented in person or by proxy at the 
special meeting of Meridian shareholders called to approve the 
Meridian/CoreStates Merger Agreement in order for a quorum to be present for 
purposes of voting on the Meridian/CoreStates Merger Agreement. The approval 
and adoption of the Meridian/CoreStates Merger Agreement will require the 
affirmative vote of the holders of a majority of the shares of Meridian 
Common Stock present and voting at the special meeting of Meridian 
shareholders. 

   As of the Meridian Record Date, directors and executive officers of 
Meridian and their affiliates beneficially owned and were entitled to vote 
4,970,703 shares of Meridian Common Stock, which represented approximately 
8.55% of the shares of Meridian Common Stock outstanding on the Meridian 
Record Date. Each Meridian director and executive officer has indicated his 
or her present intention to vote the Meridian Common Stock so owned by him or 
her for approval and adoption of the Meridian/CoreStates Merger Agreement. As 
of the Meridian Record Date, various subsidiaries of Meridian, as 
fiduciaries, custodians or agents, had sole or shared voting power with 
respect to 6,078,960 shares of Meridian Common Stock, representing 
approximately 10.46% of the shares of Meridian Common Stock outstanding on 
the Meridian Record Date. As of the Meridian Record Date, CoreStates' 
directors and executive officers beneficially owned 1,700 shares of Meridian 
Common Stock, which represented less than 0.01% of the shares of Meridian 
Common Stock outstanding on the Meridian Record Date, and various

shared voting power with respect to 94,867 shares of Meridian Common Stock, 
or 0.16% of the shares of Meridian Common Stock outstanding on the Meridian 
Record Date. Each CoreStates director and executive officer has indicated his 
or her present intention to vote all of the shares of Meridian Common Stock 
so owned by him or her for approval and adoption of the Meridian/CoreStates 
Merger Agreement. Based on the foregoing, persons holding an aggregate of 
approximately 8.5% of the outstanding shares of Meridian Common Stock on the 
Meridian Record Date have indicated their present intention to vote for 
approval and adoption of the Meridian/CoreStates Merger Agreement. 

   CoreStates. Shareholders of CoreStates entitled to cast at least a 
majority of the votes which all shareholders are entitled to cast on the 
record date (the "CoreStates Record Date," which has been established as the 

                                      29 
    

<PAGE>
   
close of business on December 18, 1995) must represented in person or by 
proxy at the special meeting of CoreStates shareholders called to approve the 
Meridian/CoreStates Merger Agreement in order for a quorum to be present for 
purposes of voting on the Meridian/CoreStates Merger Agreement and the 
proposal to amend the Articles of Incorporation of CoreStates to increase 
authorized shares of CoreStates Common Stock (the "CoreStates Charter 
Amendment"). See "DESCRIPTION OF CORESTATES CAPITAL STOCK -- General." The 
approval and adoption of the Meridian/CoreStates Merger Agreement and the 
approval of the CoreStates Charter Amendment will each require the 
affirmative vote of the holders of a majority of the shares of CoreStates 
Common Stock present and voting at the special meeting of CoreStates 
shareholders. The approval of the Meridian/CoreStates Merger Agreement and 
the CoreStates Charter Amendment are each contingent upon approval of both 
such proposals by CoreStates shareholders. Unless both proposals are 
approved, neither will be effected by CoreStates, and the Meridian/CoreStates 
Merger will not be consummated. 

   As of the CoreStates Record Date, directors and executive officers of 
CoreStates and their affiliates beneficially owned and were entitled to vote 
1,688,238 shares of CoreStates Common Stock, which represented approximately 
1.22% of the shares of CoreStates Common Stock outstanding on the CoreStates 
Record Date. Each CoreStates director and executive officer has indicated his 
or her present intention to vote the CoreStates Common Stock so owned by him 
or her for approval of the Meridian/CoreStates Merger Agreement and the 
CoreStates Charter Amendment. As of the CoreStates Record Date, CoreStates 
and its subsidiaries, as fiduciaries, custodians or agents, had sole or 
shared voting power with respect to 2,357,967 shares of CoreStates Common 
Stock, representing approximately 1.71% of the shares of CoreStates Common 
Stock outstanding on the CoreStates Record Date. As of the CoreStates Record 
Date, Meridian's directors or executive officers beneficially owned 4,132 
shares of CoreStates Common Stock, which represented less than 0.01% of the 
shares of CoreStates Common Stock outstanding on the CoreStates Record Date, 
and various subsidiaries of Meridian, as fiduciaries, custodians of agents, 
had sole of shared voting power with respect to 373,027 shares of CoreStates 
Common Stock, representing approximately 0.16% of the shares of CoreStates 
Common Stock outstanding on the CoreStates Record Date. Each Meridian 
director and executive officer has indicated his or her present intention to 
vote all of the shares of CoreStates Common Stock so owned by him or her for 
approval and adoption of the Meridian/ CoreStates Merger Agreement and 
approval of the CoreStates Charter Amendment. Based on the foregoing, persons 
holding an aggregate of approximately 1.23% of the shares of Core-States 
Common Stock outstanding on the CoreStates Record Date have indicated a 
present intention to vote for approval and adoption of the 
Meridian/CoreStates Merger Agreement and approval of the CoreStates Charter 
Amendment. 
    

MERIDIAN/CORESTATES EFFECTIVE TIME 

   The Meridian/CoreStates Effective Time will be the time of the filing of 
Articles of Merger with the Secretary of the Commonwealth of Pennsylvania or 
such later time as is specified in such Articles of Merger. The closing of 
the Meridian/CoreStates Merger will occur on the first day which is at least 
two business days after satisfaction or waiver (subject to applicable law) of 
the conditions to completion of the Meridian/CoreStates Merger set forth in 
the Meridian/CoreStates Merger Agreement (excluding conditions that, by their 
terms, cannot be satisfied until the date of closing) unless another date is 
agreed to in writing by Meridian and CoreStates. The Meridian/CoreStates 
Merger Agreement may be terminated by either party if, among other reasons, 
the Merger is not completed on or before September 30, 1996. See "-- 
Conditions to Completion of the Meridian/CoreStates Merger" and "-- 
Termination; Possible Exchange Ratio Increase" below. 

CONDUCT OF BUSINESS PENDING MERIDIAN/CORESTATES MERGER AND RELATED MATTERS 

   Pursuant to the Meridian/CoreStates Merger Agreement, each of CoreStates 
and Meridian has made certain covenants, with respect to itself and its 
subsidiaries, relating to the conduct of business pending completion of the 
Meridian/CoreStates Merger. Among other things, each has agreed (except as 
otherwise contemplated by the Meridian/CoreStates Merger Agreement or with 
the written consent of the other party) not to do any of the following: 

       (i) conduct its business other than in the ordinary and usual course; 

       (ii) issue, sell or otherwise permit to become outstanding any 
   additional shares of capital stock or give any person the right to acquire 
   any such shares, other than (a) pursuant to the exercise of stock options 
   outstanding on October 10, 1995, (b) in connection with acquisitions of 
   businesses otherwise permitted pending the Meridian/CoreStates Merger,

                                      30

   including the Merger, (c) in the case of CoreStates, pursuant to (x) employee
   benefit plans in effect on October 10, 1995 or (y) a rights agreement which
   CoreStates may enter into pending the Meridian/CoreStates Merger of similar
   effect as the Meridian rights agreement relating to its shareholder rights
   plan or (d) under the relevant Stock Option Agreement;

       (iii) make, declare or pay dividends on shares of its capital stock 
   other than regular quarterly cash dividends of $.37 per share of Meridian 
   Common Stock and $.34 per share of CoreStates Common Stock (provided that 
   CoreStates may increase its first quarterly dividend in 1996 and 
   thereafter and in such case the limit on dividends payable on Meridian 
   Common Stock will increase proportionately) and dividends by a wholly 
   owned subsidiary, or redeem or otherwise acquire shares of its capital 
   stock; 

       (iv) in the case of Meridian, increase any salaries or employee 
   benefits or enter into or modify any employee agreements (other than 
   certain termination agreements contemplated by the Meridian/CoreStates 
   Merger Agreement) or benefit plans, except for certain increases in the 
   ordinary course of business, as required by law, to satisfy pre-existing 
   contractual obligations; 

       (v) dispose of any material assets, business or property or acquire 
   material business or property of any other entities except that (a) 
   Meridian may complete the Merger and (b) CoreStates may make acquisitions 
   in which the aggregate purchase price paid does not exceed $1.0 billion or 
   in which the aggregate number of CoreStates shares issued does not exceed 
   20% of the number of such shares outstanding on September 30, 1995; 

       (vi) amend its articles of incorporation or bylaws or, in the case of 
   Meridian, the Meridian Rights Agreement, except that CoreStates may amend 
   its Articles of Incorporation to increase its authorized capital stock 
   (see "DESCRIPTION OF CORESTATES CAPITAL STOCK -- General" herein); 

       (vii) change its accounting methods; 

       (viii) knowingly take any action that (a) would, or is reasonably 
   likely to, prevent or impede the Meridian/CoreStates Merger from 
   qualifying for "pooling of interests" accounting treatment or as a 
   reorganization within the meaning of Section 368(a) of the Code, or (b) is 
   intended or is reasonably likely to result in a breach of any 
   representation or warranty, a condition not being satisfied or a violation 
   of either Stock Option Agreement or of the Meridian/CoreStates Merger 
   Agreement; or 

       (ix) incur any long-term debt other than in the ordinary course. 

   The Meridian/CoreStates Merger Agreement also provides that without the 
prior written consent of the other party, neither Meridian nor CoreStates 
will solicit or encourage inquiries or proposals with respect to, or engage 
in negotiations concerning, or provide any confidential information to, or 
have any discussions with, any person relating to a Takeover Proposal (as 
defined in the Meridian/CoreStates Merger Agreement).

Section 368(a) of the Code and (u) the conduct of the business in the ordinary
course and the absence of certain changes since December 31, 1994 which would be
likely to have a Material Adverse Effect (as defined in the Meridian/CoreStates
Merger Agreement). The Meridian/CoreStates Merger Agreement provides that no
representation or warranty shall be deemed to be untrue or incorrect as a result
of the existence or absence of any fact, if such fact together with all other
facts inconsistent with any such representation or warranty, is not reasonably
likely to have a Material Adverse Effect, except that certain representations
and warranties, including those concerning subsidiaries, corporate power and
authority, the inapplicability of certain takeover laws, the required vote and
the conduct of the business in the ordinary course, must be true and correct in
all material respects.

CONDITIONS TO COMPLETION OF THE MERIDIAN/CORESTATES MERGER 

   Each party's obligation to effect the Meridian/CoreStates Merger is 
subject to various conditions which include, in addition to other customary 
closing conditions, the following: 

   
       (i) approval of the Meridian/CoreStates Merger Agreement by the 
   requisite vote of the shareholders of CoreStates and Meridian; 

       (ii) receipt of all required regulatory approvals without the 
   imposition of any condition or restriction which would reasonably be 
   expected either (x) to have a Material Adverse Effect after the 
   Meridian/CoreStates Effective Time on the present or prospective 
   consolidated financial condition, business or operating results of 
   CoreStates, or (y) to prevent the parties from realizing a major portion 
   of the economic benefits of the Meridian/CoreStates Effective Time that 
   they anticipated at the date of entering into the Meridian/CoreStates 
   Merger Agreement; 

       (iii) the receipt of any required third party consents; 

       (iv) no court or agency having taken any action, nor law or regulation 
   having been enacted or adopted, which prohibits the Meridian/CoreStates 
   Merger; 

       (v) the receipt of letters from each party's independent auditors 
   relating to "pooling of interests" accounting treatment for the 
   Meridian/CoreStates Merger; 

       (vi) in the case of Meridian, the continued accuracy of the 
   representations and warranties of Core- States, the performance by 
   CoreStates of all covenants and the delivery by CoreStates of an officers'

the party benefitted thereby. 
    

DIVIDENDS 

   Each of CoreStates and Meridian has elected to continue to declare until 
the Meridian/CoreStates Effective Time their respective regularly scheduled 
dividends. The Meridian/CoreStates Merger Agreement requires each of 
CoreStates and Meridian to coordinate with the other the payment of dividends 
with the intent that holders of CoreStates Common Stock and Meridian Common 
Stock shall not receive two dividends, or fail to receive one dividend, for 
any calendar quarter.

REGULATORY APPROVALS REQUIRED 

   The Meridian/CoreStates Merger is subject to the prior approval of the 
Federal Reserve Board and the banking authorities of the Commonwealth of 
Pennsylvania and the States of New Jersey and Delaware. In addition, aspects 
of the Meridian/CoreStates Merger will require notifications to, and/or 
approvals from, certain other federal and state authorities. 

   
   The Meridian/CoreStates Merger is subject to approval by the Federal 
Reserve Board under Sections 3 and 4 of the Bank Holding Company Act of 1956, 
as amended (the "BHCA"). CoreStates filed applications for such approvals 
with the Federal Reserve Board on December 12, 1995. Under Section 3 of the 
BHCA, the Federal Reserve Board must withhold approval of the 
Meridian/CoreStates Merger if it finds that the transaction would result in a 
monopoly or be in furtherance of any combination or conspiracy to monopolize 
or attempt to monopolize the business of banking in any part of the United 
States. In addition, the Federal Reserve Board may not approve the 
Meridian/CoreStates Merger if it finds that the effect thereof may be 
substantially to lessen competition or to tend to create a monopoly or would 
in any other matter be in restraint of trade, unless it finds that any such 
anti-competitive effects are clearly outweighed in the public interest by the 
probable effects of the Meridian/CoreStates Merger in meeting the convenience 
and needs of the communities to be served. In each case, the Federal Reserve 
Board will also take into consideration the financial and managerial 
resources and future prospects of the banking subsidiaries following the 
transactions. The Federal Reserve Board has indicated that it will not 
approve a significant acquisition unless the resulting institution has 
sufficient capitalization, taking into account, among other things, asset 
quality. 
    

   In addition, under the Community Reinvestment Act of 1977, as amended (the 
"CRA"), the Federal Reserve Board must take into account the record of 
performance of each of CoreStates and Meridian in meeting the credit needs of 
the entire community, including low and moderate income neighborhoods, served 
by each company. As part of its review process in merger transactions, the 
Federal Reserve Board frequently receives protests from community groups and 
others. All of the banking subsidiaries of CoreStates and Meridian have 
received either an "outstanding" or a "satisfactory" CRA rating in their most 
recent CRA examinations by their respective federal regulators. 

   Under the Riegle-Neal Interstate Banking and Branching Efficiency Act of 
1994 (the "Interstate Act"), certain sections of which became effective 
September 29, 1995, the Federal Reserve Board generally may not approve an 
application if the applicant (including all insured depository institutions 
which are affiliates of the applicant), upon completion of the acquisition, 
would control more than 10% of the total deposits of all insured depository 
institutions in the United States or 30% or more of the total amount of 
deposits of all insured depository institutions in a particular state. 
CoreStates does not believe that after the Meridian/CoreStates Merger it 
would control deposits in excess of either limitation. 

   The Federal Reserve Board will furnish notice and a copy of the 
application for approval of the Meridian/CoreStates Merger to the Office of 
the Comptroller of the Currency (the "OCC"), the Federal Deposit Insurance 
Corporation (the "FDIC") and the appropriate state regulatory authorities. 
These agencies have 30 days to submit their views and recommendations to the 
Federal Reserve Board. The Federal Reserve Board is required to hold a public 
hearing in the event it receives a written recommendation of disapproval of 
the application from any of these agencies within such 30-day period. 
Furthermore, the BHCA and Federal Reserve Board regulations require 
publication of notice of, and the opportunity for public comment on the 
application submitted by CoreStates for approval of the Meridian/CoreStates 
Merger and authorize the Federal Reserve Board to hold a public hearing in 
connection therewith if the Federal Reserve Board determines that such a 
hearing would be appropriate. Any such hearing or comments provided by third 
parties could prolong the period during which the application is subject to 
review by the Federal Reserve Board. 

   Under Section 3 of the BHCA, the Meridian/CoreStates Merger may not be 
completed for 30 days from the date of approval by the Federal Reserve Board, 
during which time the Merger could be challenged on antitrust grounds. With 
the approval of the Federal Reserve Board and the Department of Justice, 
however, this waiting period may be reduced to no less than 15 days. The 
commencement of an antitrust action by the Justice Department would stay the 
effectiveness of Federal Reserve Board approval of the Meridian/CoreStates 
Merger unless a court specifically orders otherwise. In reviewing 

                                      33 

<PAGE>

the Meridian/CoreStates Merger, the Justice Department could analyze the
Meridian/CoreStates Merger's effect on competition differently than the Federal
Reserve Board, and thus it is possible that the Justice Department could reach a
different conclusion than the Federal Reserve Board regarding competitive
effects.

   Under Section 4 of the BHCA and related regulations, the Federal Reserve 
Board must consider whether the performance of CoreStates' and Meridian's 
nonbanking activities on a combined basis can reasonably be expected to 
produce benefits to the public (such as greater convenience, increased 
competition and gains in efficiency) that outweigh possible adverse effects 
(such as undue concentration of resources, decreased or unfair competition, 
conflicts of interest and unsound banking practices). This consideration 
includes an evaluation of the financial and managerial resources of 
CoreStates and Meridian and the effect of the proposed transaction on those 
resources. 

   Using the above standards, CoreStates and Meridian expect that the Federal 
Reserve Board or the Justice Department will request that CoreStates and/or 
Meridian divest certain operations in order to alleviate what such agencies 
believe would otherwise be an adverse competitive effect. At present, only 
preliminary discussions with regulatory authorities have taken place and the 
nature and amount of divestitures cannot be determined until further 
discussions with the Federal Reserve Board and the Justice Department are 
held; accordingly, as of the date of this Supplement, neither CoreStates nor 
Meridian can predict with any assurance what the aggregate amount of any such 
divestitures might be. While any potential divestitures may affect certain 
pro forma combined financial statement amounts, merger and restructuring 
costs, cost savings and revenues, CoreStates and Meridian believe, based on 
divestitures required in recent comparable transactions, that the aggregate 
amount and financial impact of divestitures should not be material to the 
business, operations or financial condition of CoreStates and its 
subsidiaries, taken as a whole. Under the Meridian/CoreStates Merger 
Agreement, CoreStates and Meridian are not obligated to complete the 
Meridian/CoreStates Merger if any requisite approval or consent of a 
Regulatory Authority (as defined in the Meridian/CoreStates Merger Agreement) 
is subject to the imposition of any condition or restriction which would be 
reasonably expected either (i) to have a Material Adverse Effect (as defined 
in the Meridian/CoreStates Merger Agreement) after the Meridian/CoreStates 
Effective Time in the present or prospective consolidated financial 
condition, business or operating results of CoreStates, or (ii) to prevent 
the parties from realizing the major portion of the economic benefits of the 
Meridian/CoreStates Merger and the transactions contemplated thereby that 
they anticipated obtaining therefrom on the date of the Meridian/CoreStates 
Merger Agreement. 

   The Meridian/CoreStates Merger will be subject to the prior approval of 
the banking regulatory authorities of Pennsylvania, New Jersey and Delaware. 
The factors that such state banking authorities will consider in determining 
whether to grant their approval include the competitive effects of the 
Meridian/CoreStates Merger, the principles of sound banking and the public 
interest and the needs of the communities served by CoreStates and Meridian. 
Information regarding the competitive effects of the Meridian/CoreStates 
Merger is also being provided to the Attorney General of Pennsylvania. 

   
   CoreStates' and Meridian's rights to exercise their respective options 
under the Stock Option Agreements are also subject to the prior approval of 
the Federal Reserve Board, to the extent that the exercise of such respective 
options would result in CoreStates or Meridian, as the case may be, owning 
more than 5% of the outstanding shares of the other party's common stock. In 
considering whether to approve CoreStates' or Meridian's right to exercise 
its option, the Federal Reserve Board would generally apply the same 
statutory criteria it would apply to its consideration of approval of the 
Meridian/CoreStates Merger. 

   There can be no assurance as to whether or when any of the above-described 
regulatory approvals required for completion of the Meridian/CoreStates 
Merger will be obtained or as to any conditions that may be imposed in 
connection with the granting of such approvals. See "-- Conditions to 
Completion of the Meridian/CoreStates Merger." 
    

CERTAIN FEDERAL INCOME TAX CONSEQUENCES 

   The following describes the principal federal income tax consequences of 
the Meridian/CoreStates Merger under the Code, assuming that the 
Meridian/CoreStates Merger is completed as contemplated herein. This 

                                      34 

<PAGE>
discussion is based on current laws and interpretations thereof, which are 
subject to change. The discussion assumes that the Meridian Common Stock 
exchanged by each holder thereof in the Meridian/CoreStates Merger is held as 
a capital asset and does not take account of rules that may apply to holders 
of Meridian Common Stock ("Meridian Shareholders") that are subject to 
special treatment under the Code (including, without limitation, insurance 
companies, dealers in securities, certain retirement plans, financial 
institutions, tax exempt organizations, shareholders who acquired shares 
pursuant to the exercise of an employee stock option or otherwise as 
compensation or foreign persons). Also, the discussion does not address 
state, local or foreign tax consequences. 

   Tax Opinions. The obligations of CoreStates and of Meridian to complete 
the Meridian/CoreStates Merger are subject to the receipt of the opinions of 
tax counsel outlined below, unless waived. Neither CoreStates nor Meridian 
has requested or will request an advance ruling from the Internal Revenue 
Service (the "IRS") as to the tax consequences of the Meridian/CoreStates 
Merger. 

   As of the date of the joint proxy statement prospectus to be mailed to 
shareholders of Meridian and Core- States in connection with the 
Meridian/CoreStates Merger, Simpson Thacher & Bartlett, counsel to 
CoreStates, and Stevens & Lee, counsel to Meridian, will have advised 
CoreStates and Meridian, respectively, that in their opinion, based on 
certain customary representations and assumptions referred to in such 
opinions, (i) the Meridian/CoreStates Merger will be treated for federal 
income tax purposes as a "reorganization" within the meaning of Section 
368(a) of the Code and (ii) no income, gain or loss will be recognized for 
federal income tax purposes by Meridian shareholders upon the exchange in the 
Meridian/CoreStates Merger of shares of Meridian for shares of CoreStates 
(except to the extent of any cash received in lieu of fractional shares). In 
addition, completion of the Meridian/CoreStates Merger is conditioned upon 
the receipt by CoreStates and Meridian of the opinions described above dated 
as of the closing date of the Meridian/CoreStates Merger. 

   Cash Received in Lieu of Fractional Shares. A Meridian Shareholder who 
receives cash in the Meridian/CoreStates Merger in lieu of a fractional share 
interest in CoreStates Common Stock will be treated for federal income tax 
purposes as receiving such fractional share interest and then redeeming it 
for cash. Such a Meridian Shareholder will recognize gain or loss as of the 
Meridian/CoreStates Effective Time in an amount equal to the difference 
between the amount of cash received and the portion of the shareholder's 
adjusted tax basis in the shares of Meridian Common Stock allocable to the 
fractional share interest. Any gain or loss will be capital gain or loss if 
the shareholder holds the Meridian Common Stock as a capital asset at the 
CoreStates/Meridian Merger and will be long-term capital gain or loss if the 
holding period for the fractional share interest deemed to be received and 
then redeemed is more than one year. 

   Tax Basis and Holding Period of CoreStates Common Stock. The tax basis of 
the shares of CoreStates Common Stock received by Meridian shareholders will 
be the same as the tax basis of their Meridian Common Stock exchanged 
therefor (reduced by any amount allocable to a fractional share interest for 
which cash is received). The holding period of CoreStates Common Stock 
received by Meridian Shareholders will include the holding period of their 
Meridian Common Stock exchanged therefor, provided such Meridian Common Stock 
is held as a capital asset at the Meridian/CoreStates Effective Time. 

ANTICIPATED ACCOUNTING TREATMENT 

   
   Management of each of Meridian and CoreStates expect the 
Meridian/CoreStates Merger to qualify as a "pooling of interests" for 
accounting and financial reporting purposes. 

   The Meridian/CoreStates Merger Agreement provides that a condition to 
completion of the Meridian/CoreStates Merger is the receipt of letters from 
Ernst & Young LLP, independent auditors for Core- States, and KPMG Peat 
Marwick LLP, independent auditors for Meridian, concurring with managements' 
conclusions that the Meridian/CoreStates Merger qualifies for "pooling of 
interests" accounting treatment. 
    

TERMINATION; POSSIBLE EXCHANGE RATIO INCREASE 

   The Meridian/CoreStates Merger Agreement may be terminated at any time 
prior to the Meridian/CoreStates Effective Time, by action taken or 
authorized by the Board of Directors of the terminating party or parties, 
whether before or after approval and adoption of the Meridian/CoreStates 
Merger Agreement by the shareholders of Meridian or CoreStates: (a) by mutual 
consent of CoreStates and Meridian; (b) by either CoreStates or Meridian if the

                                      35 

<PAGE>

CoreStates/Merger is not completed by September 30, 1996 (except to the extent
that the failure of the Meridian/CoreStates Merger then to be completed arises
out of or results from the knowing action or inaction of the terminating party);
or (c) by either CoreStates or Meridian if (i) the consent of the Federal
Reserve Board for completion of the Meridian/CoreStates Merger and the other
transactions contemplated by the Meridian/CoreStates Merger Agreement has been
denied by final action and the time for appeal has expired or (ii) any approval
of the shareholders of Meridian or of CoreStates required for the completion of
the Meridian/CoreStates Merger has not been obtained. The Meridian/CoreStates
Merger Agreement may also be terminated at any time prior to (a) the Meridian
special meeting of shareholders to approve the Meridian/CoreStates Merger
Agreement, by CoreStates, if the Board of Directors of Meridian fails to
recommend to its shareholders the approval of the Meridian/CoreStates Merger or
withdraws or modifies or changes such recommendation in a manner adverse to
CoreStates, and (b) the CoreStates special meeting of shareholders to approve
the Meridian/CoreStates Merger Agreement, by Meridian, if the Board of Directors
of CoreStates fails to recommend to its shareholders approval of the
Meridian/CoreStates Merger and the related amendment to the Articles of
Incorporation of CoreStates or withdraws or modifies or changes such
recommendations in a manner adverse to Meridian.

   In addition, the Meridian/CoreStates Merger Agreement may be terminated by 
the Meridian Board of Directors at its sole option, if either: 

       (i) both (a) the Average Closing Price on the Determination Date (i.e., 
   the average closing price of CoreStates Common Stock for the ten full 
   trading days ending on the date the Federal Reserve Board approves the 
   Meridian/CoreStates Merger) is less than $32.725 and (b) the number 
   obtained by dividing the Average Closing Price on the Determination Date 
   by $38.50 (the "CoreStates Ratio") is less than the number obtained by 
   dividing the Index Price (being the weighted average on a given date of 
   the closing prices of the companies composing the Index Group described 
   below) on the Determination Date by $41.71 (being the Index Price on 
   October 9, 1995) and subtracting .15 from such latter number (after such 
   subtraction, the "Index Ratio"); or 

       (ii) the Average Closing Price on the Determination Date is less than 
   $27.75 (the number obtained by multiplying $37.00 (being the last sale 
   price of CoreStates Common Stock on October 10, 1995 on the NYSE Tape) and 
   0.75); 

provided, however, that the Meridian/CoreStates Merger Agreement would not be 
so terminated if Core- States elects, at its sole option, to increase the 
Meridian/CoreStates Exchange Ratio as set forth in the Meridian/CoreStates 
Merger Agreement and as illustrated below. There can be no assurance that the 
Meridian Board of Directors would exercise its right to terminate the 
Meridian/CoreStates Merger Agreement if a Termination Event (i.e., the 
conditions in either (i) or (ii) above) exists, and if the Meridian Board of 
Directors does elect to so terminate the Meridian/CoreStates Merger 
Agreement, there can be no assurance that CoreStates will elect to increase 
the Meridian/CoreStates Exchange Ratio as provided in the Meridian/CoreStates 
Merger Agreement and as illustrated below. 

   Certain possible effects of the above provisions of the 
Meridian/CoreStates Exchange Ratio may be illustrated by the following four 
scenarios: 

   
       (1) If the Average Closing Price on the Determination Date is not less 
   than $32.725, there would be no Termination Event and no adjustment to the 
   Meridian/CoreStates Exchange Ratio. 

       (2) If the Average Closing Price on the Determination Date is less than 
   $32.725 and greater than or equal to $27.75, but the CoreStates Ratio is 
   equal to or greater than the Index Ratio, there would be no Termination 
   Event and no increase in the Meridian/CoreStates Exchange Ratio. 

       (3) If the Average Closing Price on the Determination Date is less than 
   $32.725 and the CoreStates Ratio is less than the Index Ratio, there would 
   be a Termination Event and the Meridian Board of Directors could, at its 
   sole option, elect to terminate the Meridian/CoreStates Merger Agreement; 
   provided that CoreStates could, at its sole option, override such 
   termination by electing to increase the Meridian/CoreStates Exchange Ratio 
   to equal the lesser of (i) the result of dividing $40.09 (the product of 
   $32.725 and the Exchange Ratio) by the Average Closing Price on the 
   Determination Date, and (ii) the result of dividing the product of the 
   Index Ratio and the Meridian/CoreStates Exchange Ratio (as then in 
   effect), by the CoreStates Ratio. 
    
                                      36 

<PAGE>
   
       (4) If the Average Closing Price on the Determination Date is less than 
   $27.75, there would be a Termination Event and the Meridian Board of 
   Directors could, at its sole option, elect to terminate the 
   Meridian/CoreStates Merger Agreement, provided that CoreStates could, at 
   its sole option, override such termination by electing to increase the 
   Meridian/CoreStates Exchange Ratio to equal the quotient obtained by 
   dividing $33.99 (the product of $27.75 and the Meridian/CoreStates 
   Exchange Ratio (as then in effect)) by the Average Closing Price. 
       These four scenarios may be summarized as follows:

        [$27.75                     --                               yes 
</TABLE>

    
   If there would be a Termination Event described in both paragraphs (3) and 
(4) above, the Meridian Board of Directors could elect which Termination 
Event to assert. The above scenarios are for illustrative purposes only and 
are not intended to, and do not, reflect the value of the CoreStates Common 
Stock that may actually be received by holders of Meridian Common Stock in 
the Meridian/CoreStates Merger, nor do they reflect all possible 
termination/increase scenarios. 

   The Average Closing Price on the Determination Date on which the 
occurrence of a Termination Event and the subsequent increase, if any, in the 
Meridian/CoreStates Exchange Ratio may be determined, will be based on the 
average of the last sale prices of CoreStates Common Stock during the ten-day 
period ending on the Determination Date. Accordingly, because the market 
price of CoreStates Common Stock between the Determination Date and the 
effective time of the Meridian/CoreStates Merger, as well as on the date 
certificates representing shares of CoreStates Common Stock are delivered in 
exchange for shares of Meridian Common Stock following completion of the 
Meridian/CoreStates Merger, will fluctuate and possibly decline, the value of 
the CoreStates Common Stock actually received by holders of Meridian Common 
Stock may be more or less than (i) the Average Closing Price on the 
Determination Date, or (ii) the value of the CoreStates Common Stock on the 
Closing Date resulting from the Meridian/CoreStates Exchange Ratio or any 
possible adjustment to the Meridian/CoreStates Exchange Ratio as illustrated 
above. 

   
   At the close of business on December 15, 1995, the Index Price was $43.18 
    

   The Index Group consists of 11 bank holding companies selected by 
CoreStates and Meridian as being directly relevant for purposes of 
distinguishing changes in CoreStates; stock prices that are unique from those 
reflective of general changes in comparable companies. The 11 bank holding 
companies are Bank of Boston, Barnett Banks, Inc., Boatmen's Bancshares, 
Inc., Comerica, First Bank System Inc., Fleet Financial Group, Inc., KeyCorp, 
Mellon Bank Corporation, National City Corporation, PNC Financial Corp and 
The Bank of New York Company, Inc. If CoreStates or any company belonging to 
the Index Group declares or effects a stock dividend, reclassification, 
recapitalization, split-up, combination, exchange of shares or similar 
transaction between October 10, 1995 and the Determination Date, the prices 
of CoreStates Common Stock or such other common stocks shall be appropriately 
adjusted for all purposes, including determining whether there is a 
Termination Event or determining any possible increase in the 
Meridian/CoreStates Exchange Ratio as illustrated above (and, in the case of 
any such transaction by CoreStates, the Meridian/CoreStates Exchange Ratio 
also shall be appropriately adjusted). In the event the common stock of any 
such company ceases to be publicly traded or there has been an announcement 
of a proposal for the acquisition or sale of such company, such company will 
be removed from the Index Group and the weights will be redistributed 
proportionately for purposes of determining whether there has been a 
Termination Event. 

   It is not possible to know whether a Termination Event will occur until 
after the Determination Date. The Meridian Board of Directors has made no 
decision as to whether it would exercise its right to terminate the 
Meridian/CoreStates Merger Agreement if there is a Termination Event. In 
considering whether to exercise its termination right in such situation, the 
Meridian Board of Directors would, consistent with its fiduciary duties, take 
into account all relevant facts and circumstances that exist at such time and 
would consult with its financial advisors and legal counsel. Approval of 

                                      37

the Meridian/CoreStates Merger Agreement by the shareholders of Meridian at the
Meridian special meeting of shareholders will confer on the Meridian Board of
Directors the power, consistent with its fiduciary duties, to elect to complete
the Meridian/CoreStates Merger in the event of a Termination Event whether or
not there is any increase in the Meridian/CoreStates Exchange Ratio and without
any further action by, or resolicitation of, the shareholders of Meridian. If
the Meridian Board of Directors elects to exercise its termination right,
Meridian must give CoreStates prompt notice of that decision during a ten-day
period. During the five-day period commencing with receipt of such notice,
CoreStates has the option, in its sole discretion, to increase the
Meridian/CoreStates Exchange Ratio in the manner set forth in the
Meridian/CoreStates Merger Agreement and as illustrated above and thereby avoid
such termination of the Meridian/CoreStates Merger Agreement. CoreStates is
under no obligation to increase the Meridian/CoreStates Exchange Ratio, and
there can be no assurance that CoreStates would elect to increase the
Meridian/CoreStates Exchange Ratio if the Meridian Board of Directors were to
exercise its right to terminate the Meridian/CoreStates Merger Agreement as set
forth above. Any such decision would be made by CoreStates in light of the
circumstances existing at the time CoreStates has the opportunity to make such
an election. If CoreStates elects to increase the Meridian/CoreStates Exchange
Ratio, no termination of the Meridian/CoreStates Merger Agreement would occur as
a result of a Termination Event.

   
   Although CoreStates has the right in the limited circumstances described 
above to increase the Meridian/CoreStates Exchange Ratio, under no 
circumstances may the Meridian/CoreStates Exchange Ratio be decreased. 
    

   In the event of termination of the Meridian/CoreStates Merger Agreement by 
either Meridian or CoreStates, there will be no liability or obligation on 
the part of CoreStates or Meridian other than the obligation dealing with 
confidentiality, and other than any liabilities or damages incurred as a 
result of the willful breach by a party of any of its representations, 
warranties, covenants or agreements set forth in the Meridian/CoreStates 
Merger Agreement. 

AMENDMENT AND WAIVER 

   Prior to the Meridian/CoreStates Effective Time, any provision of the 
Meridian/CoreStates Merger Agreement may be: (i) waived by the party 
benefitted by the provision; or (ii) amended or modified at any time by an 
agreement in writing among the parties thereto, approved by their respective 
Boards of Directors and executed in the same manner as the 
Meridian/CoreStates Merger Agreement, provided that, after approval by the 
shareholders of Meridian, the consideration to be received by the 
shareholders of Meridian Common Stock may not thereby be decreased. 

INTERESTS OF CERTAIN PERSONS IN THE MERIDIAN/CORESTATES MERGER 

   Certain members of the Boards of Directors and management of CoreStates 
and Meridian may be deemed to have certain interests in the 
Meridian/CoreStates Merger in addition to their interests generally as 
shareholders of CoreStates or Meridian, as the case may be. All of such 
additional interests are described below, to the extent material, and except 
as described below such persons have, to the best knowledge of CoreStates and 
Meridian, no material interests in the Meridian/CoreStates Merger apart from 
those of shareholders generally. The CoreStates Board of Directors and the 
Meridian Board of Directors were each aware of these interests of their 
respective directors and officers and considered them, among other matters, 
in approving the Meridian/CoreStates Merger Agreement and the transactions 
contemplated thereby. 

   Indemnification and Board Membership. The Meridian/CoreStates Agreement 
provides that CoreStates will maintain all rights of indemnification existing 
in favor of the directors, officers and employees of Meridian for six years 
(and, with respect to transactions arising out of the Meridian/CoreStates 
Merger Agreement or the Stock Option Agreements, indefinitely) after the 
Meridian/CoreStates Effective Time to the full extent that Meridian would 
have been permitted under Pennsylvania law and the Meridian Articles of 
Incorporation (the "Meridian Charter") and By-laws to indemnify such person 
and will cause to be maintained for six years after the Meridian/CoreStates 
Effective Time directors' and officers' liability insurance on terms no less 
favorable than those contained in policies maintained by Meridian; provided 
that if the annual premium payments for such insurance exceeds 250% of the 
annual premiums paid as of the date of the Meridian/CoreStates Merger 
Agreement by Meridian, CoreStates is required to maintain the maximum 
coverage available at an annual premium equal to 250% of Meridian's annual 
premium. 

                                      38 

<PAGE>
   The Board of Directors of CoreStates as of the Meridian/CoreStates 
Effective Time is expected to consist of persons currently serving as 
directors of CoreStates and Meridian, and certain officers of CoreStates and 
Meridian will become officers of CoreStates as of the Effective Time. See "-- 
Management and Operations After the Merger." 

   
   Termination Agreements. Prior to the execution of the Meridian/CoreStates 
Merger Agreement, four executive officers of Meridian, Messrs. McCullough, 
Sparks, Grosz and Fenimore, were parties to termination agreements. Under the 
terms of the Meridian/CoreStates Merger Agreement, (i) Messrs. Fenimore and 
Grosz were to retain their existing termination agreements, and (ii) Messrs. 
McCullough and Sparks were to enter into new termination agreements. With the 
consent of CoreStates, Meridian will not enter into a new termination 
agreement with Mr. McCullough and Mr. McCullough will retain his existing 
termination agreement. Mr. Sparks and five other senior executives, Ms. P. 
Sue Perrotty, a Group Executive Vice President of Meridian, Mr. R. William 
Holland, an Executive Vice President of Meridian, Mr. Wayne R. Huey, an 
Executive Vice President of Meridian, Mr. Richard E. Meyers, an Executive 
Vice President of Meridian and Mr. Thomas G. Strohm, an Executive Vice 
President of Meridian, are to enter into new termination agreements pursuant 
to the Meridian/CoreStates Merger Agreement, which, in the case of Mr. 
Sparks, will supersede the prior agreement with Meridian. 

   In the event, and only in the event, an executive's employment is 
terminated under the circumstances hereinafter described, each executive 
would be entitled to receive cash payments ("Termination Payments"). The 
factors that provide the basis for calculating Termination Payments vary over 
time, and consequently a sum certain for such Termination Payments could be 
determined only as of the specific dates upon which any such payments were 
made. Under the existing termination agreements for Messrs. McCullough, 
Fennimore and Grosz, and assuming new termination agreements are executed for 
Mr. Sparks, Ms. Perrotty and Messrs. Holland, Huey, Meyers and Strohm in the 
form contemplated by the Meridian/CoreStates Merger Agreement, then, if 
Termination Payments were determined as of the Meridian/CoreStates Effective 
Time, the total of such payments (exclusive of additional retirement 
benefits) to Messrs. McCullough, Sparks, Fennimore, Grosz, Ms. Perrotty and 
Messrs. Holland, Huey, Meyers and Strohm would be approximately $3,196,000, 
$1,742,000, $766,000, $731,000, $689,000, $511,000, $582,000, $561,000 and 
$433,000, respectively. 

   The new termination agreement for Mr. Sparks will have a three-year term 
commencing as of the Meridian/CoreStates Effective Time and provide for 
severance benefits for a period of three years in the event of the 
termination of the executive's employment without "Cause" or by the executive 
with "Good Reason" (as each such term is defined). Such severance benefits 
would consist of (i) salary continuation (based on the highest salary during 
the year of termination and the two-year period preceding termination); (ii) 
annual payments of the greater of (A) the highest bonus paid in respect of 
the year of termination or the preceding two years or (B) the highest bonus 
paid with respect to calendar years 1992-1994; (iii) annual payments of the 
highest amount contributed by the employer in the year of termination or the 
preceding three years under any tax- qualified defined contribution plans, 
supplemental salary reduction plan, defined contribution portion of a 
retirement restoration plan and other nonqualified plans; (iv) accrual of 
additional benefits under any tax-qualified defined benefit plan, 
supplemental retirement plan and defined benefit portion of a retirement 
restoration plan based on the highest compensation in the year of termination 
or the preceding three years; and (v) continued participation in welfare 
benefit plans or tax- effected payments in lieu thereof. The payments and 
benefits under this agreement will be limited to the extent necessary to 
avoid application of the "golden parachute" deduction and excise tax 
provisions of Sections 280G and 4999 of the Code. 
    

   The existing termination agreements for Messrs. McCullough, Fennimore and 
Grosz are similar to the termination agreement described above except that 
(i) such agreements do not contain the Code Sections 280G and 4999 limitation 
on the amount of payments and benefits and (ii) the agreements for Messrs. 
Fennimore and Grosz provide, in general, for two years of payments and 
benefits. 

   
   The termination agreements for Ms. Perrotty and Messrs. Holland, Huey, 
Meyers and Strohm have three- year terms commencing as of the 
Meridian/CoreStates Effective Time and provide for severance benefits for the 
balance of the term, up to a maximum of 24 months, in the event of the 
termination of an executive's employment without "Cause" or by the executive 
due to certain job changes, relocations or reductions in compensation or 
benefits. Such severance benefits would consist of (i) salary continuation 
(based on the highest salary in the three-year period preceding the executive's
    

                                      39 

<PAGE>

termination); (ii) monthly prorated payments in respect of targeted incentive
compensation for the year in which the Merger occurs; (iii) monthly prorated
payments in respect of benefits the executive would have received under the
Meridian 401(k) plan, or a successor plan, for the year prior to termination;
(iv) continued participation in Meridian's retirement plan and supplemental
retirement plan (including any successor plan); and (v) continued life,
disability and medical insurance benefits. The payments and benefits under these
agreements will be limited to the extent necessary to avoid application of the
"golden parachute" deduction and excise tax provisions of Sections 280G and 4999
of the Code.

   CoreStates had no comparable termination arrangements. However, 
approximately 24 executive officers of CoreStates generally at the level of 
Executive Vice-President and above will be offered an executive severance 
policy which is substantially equivalent to the policy covering Meridian 
executives. 

   
   The Meridian/CoreStates Merger will not, however, constitute a change of 
control or otherwise trigger or accelerate any payment for purposes of such 
severance agreements or any other agreement or arrangement between CoreStates 
and its existing executive officers. 
    

MANAGEMENT AND OPERATIONS AFTER THE MERIDIAN/CORESTATES MERGER 

   
   Directors After the Meridian/CoreStates Merger. CoreStates has agreed in 
the Meridian/CoreStates Merger Agreement to fix the size of its Board of 
Directors at 15 members, comprised of ten of the current directors of 
CoreStates and five of the current directors of Meridian, which five 
directors shall consist of Samuel A. McCullough, Robert W. Cardy, Lawrence R. 
Pugh, George Strawbridge, Jr. and Judith M. von Seldeneck ("Former Meridian 
Directors"). CoreStates has agreed in the Meridian/CoreStates Agreement to 
cause the Former Meridian Directors to be elected or appointed as directors 
of CoreStates at, or as promptly as practicable after, the 
Meridian/CoreStates Effective Time. 
    

   Two of the Former Meridian Directors, including Mr. McCullough, will be 
appointed to the class of the Board of Directors of CoreStates elected by the 
shareholders of CoreStates at the annual meeting of CoreStates immediately 
preceding the Meridian/CoreStates Effective Time. Two of the Former Meridian 
Directors will be appointed to the class of the Board of Directors of 
CoreStates elected by the shareholders of CoreStates at the annual meeting of 
CoreStates immediately preceding the annual meeting referenced in the 
preceding sentence. The remaining Former Meridian Director will be appointed 
to the remaining class of the CoreStates Board of Directors. 

   
   Except as set forth herein, the parties have not yet determined which 
members of their respective current Boards of Directors will continue as 
members of the Board of Directors of CoreStates after the Meridian/CoreStates 
Effective Time. The determination as to the composition of the Board of 
Directors of CoreStates after the Meridian/CoreStates Effective Time is not 
expected to be made until shortly before the Effective Time. Although two UCB 
directors will be added to the Meridian Board of Directors upon completion of 
the Merger, these persons are not anticipated to be among the directors to be 
considered for the CoreStates Board of Directors. 

   Management After the Meridian/CoreStates Merger. The Board of Directors of 
CoreStates has agreed in the Meridian/CoreStates Merger Agreement to take 
appropriate action so that as of the Meridian/CoreStates Effective Time, Mr. 
Larsen will be Chairman and Chief Executive Officer of CoreStates and Mr. 
McCullough will become President and Chief Operating Officer of CoreStates. 
    

   In addition, the Board of Directors of CoreStates has agreed in the 
Meridian/CoreStates Merger Agreement to take appropriate action so that as of 
the Meridian/CoreStates Effective Time the following persons will hold the 
offices of CoreStates having the functions set forth below: 

   Rosemarie B. Greco: President and Chief Executive Officer of CoreStates 
Bank, N.A. 

   Charles L. Coltman III: Vice Chairman. 

   Charles P. Connolly, Jr.: Senior Executive Vice President and Chief Risk 
Management Officer. 

   Robert N. Gilmore: Chief Processing Services Officer. 

                                      40 

<PAGE>
   David E. Sparks: Chief Financial Officer. 

   The Office of the Chairman of CoreStates after the Meridian/CoreStates 
Effective Time will consist of Messrs. Larsen, McCullough, Coltman, Connolly, 
Gilmore and Sparks and Ms. Greco. 

   As of the date hereof, neither CoreStates nor Meridian is aware of any 
material relationship between Core- States or its directors or executive 
officers and Meridian or its directors or executive officers, except as 
contemplated by the Meridian/CoreStates Merger Agreement or as described 
herein or in the documents incorporated by reference herein. In the ordinary 
course, of business and from time to time, CoreStates may do business with 
Meridian, CoreStates may enter into banking transactions with certain of 
Meridian's directors, executive officers and their affiliates, Meridian may 
do business with CoreStates, and Meridian may enter into banking transactions 
with certain of CoreStates' directors, officers and their affiliates. 

CONSOLIDATION OF OPERATIONS; ANTICIPATED COST SAVINGS 

   
   Although no assurances can be given that any specific level of expense 
savings will be achieved or as to the timing thereof, the managements of 
Meridian and CoreStates currently expect to achieve substantial savings in 
the base of operating expenses by consolidating certain operations, 
facilities and business lines and eliminating redundant expenses. Such 
savings (the principal components of which are described in greater detail 
below) are expected to be realized over time as such consolidation is 
completed. Annual pre-tax savings are expected to amount to approximately 
$186 million (or approximately 12% of the projected annual operating expense 
base) by the end of 1997, assuming among other things that the reductions in 
staff, branch consolidations and consolidations of other operations on which 
such estimates are based are accomplished within such time period. Such 
savings are expected to be realized primarily through reductions in staff, 
the consolidation and elimination of certain branches and office facilities 
and the consolidation of certain data processing and other back office 
operations. These anticipated expense savings are in addition to the 
projected savings from CoreStates' previously- announced "BEST" program and 
Meridian's previously-announced "59.9" program, which are anticipated to 
result in annual expense reductions of $145 million and $55 million, 
respectively, in 1996. It is expected that one-time, pre-tax merger-related 
and other charges of $175 million will be incurred upon completion of the 
Meridian/CoreStates Merger, principally as a result of an addition to the 
allowance for loan losses which CoreStates has determined will be necessary 
in connection with a change in strategy related to problem assets and to 
conform Meridian's consumer lending charge-off policies to those of 
CoreStates, and also as a result of severance expenses to be incurred in 
connection with anticipated staff reductions, expenses in connection with 
planned office eliminations and other Meridian/CoreStates Merger-related 
expenses, including costs to eliminate redundant back office and other 
operations of CoreStates and Meridian and other expenses related directly to 
the Meridian/CoreStates Merger. See "SELECTED COMBINED PRO FORMA FINANCIAL 
INFORMATION." While the managements of Meridian and CoreStates believe such 
expectations have a reasonable basis and have been prepared in good faith, 
the extent to which cost savings will be achieved is dependent upon various 
factors beyond the control of Meridian and CoreStates, including the 
regulatory environment, economic changes, unanticipated changes in business 
conditions and inflation. Therefore, no assurances can be given with respect 
to the ultimate level and composition of cost savings to be realized, or that 
such savings will be realized in the time frame currently anticipated. 

   Of the projected annual expense savings of $186 million expected to be 
realized from the Meridian/CoreStates Merger, approximately $112 million is 
expected to be derived from the reduction in personnel, approximately $20 
million is expected to be derived from the elimination of redundant outside 
services, approximately $12 million is expected to be derived from reduction 
in occupancy expense resulting from branch consolidations, and the remaining 
approximately $42 million is expected to be derived from other areas. 

   CoreStates and Meridian are currently conducting a branch network review 
which is expected to result in the consolidation, closing or sale of 
approximately 115 branch offices out of a combined total of 666 branches. 
CoreStates and Meridian also anticipate that less than 10% of the combined 
total of 19,127 personnel positions will need to be eliminated in order to 
achieve the projected cost savings in personnel expense described above. In 
order to reduce the number of potential layoffs associated with the 
anticipated reduction in staff positions, both CoreStates and Meridian have 
instituted hiring freezes except for critical positions.

<PAGE>
                   DESCRIPTION OF CORESTATES CAPITAL STOCK 

GENERAL 

   
   As of September 30, 1995, the authorized capital stock of CoreStates 
consisted of 10,000,000 shares of Series Preferred Stock, without par value 
("Series Preferred Stock"), of which none was issued and outstanding and 
200,000,000 CoreStates Common Stock, par value $1.00 per share, of which 
138,909,597 shares were issued and outstanding. 
    

   At the special meeting of shareholders of CoreStates to consider the 
Meridian/CoreStates Merger Agreement, the Board of Directors of CoreStates 
will submit for consideration by shareholders of CoreStates a proposal to 
amend the Articles of Incorporation of CoreStates to increase the number of 
authorized shares of Core- States Common Stock from 200,000,000 to 
350,000,000. 

   CoreStates' Board of Directors is authorized to issue the shares of Series 
Preferred Stock in series without further shareholder action with such voting 
rights, designations, preferences, qualifications, privileges, limitations, 
restrictions, options, conversion rights and other special or relative rights 
of any series as it may determine from time to time by resolution. 

CORESTATES COMMON STOCK 

   Dividend Rights. The holders of CoreStates Common Stock are entitled to 
share ratably in dividends out of funds legally available therefor, when and 
as declared by the CoreStates Board of Directors, after full cumulative 
dividends on all shares of Series Preferred Stock, and any other class or 
series of preferred stock ranking superior as to dividends to CoreStates 
Common Stock, have been paid or declared and funds sufficient for the payment 
thereof set apart. 

   Voting Rights. Each holder of CoreStates Common Stock has one vote on 
matters presented for consideration by the shareholders for each share held. 
There are no cumulative voting rights in the election of directors. All 
issued and outstanding shares of CoreStates Common Stock are fully paid and 
nonassessable. In certain circumstances, issued and outstanding Series 
Preferred Stock or any other class or series of preferred stock issued by 
CoreStates may affect voting rights of CoreStates Common Stock. There are no 
shares of Series Preferred Stock or any other class or series of preferred 
stock issued by CoreStates outstanding. 

   Size and Classification of Board of Directors. The Articles of 
Incorporation of CoreStates provide for a classified Board of Directors, 
consisting of three substantially equal classes of directors, each serving 
for a three-year term, with the term of each class of directors ending in 
successive years. The CoreStates Board of Directors currently consists of 19 
members. Classification of the Board of Directors may have the effect of 
decreasing the number of directors that could otherwise be elected at a given 
meeting by anyone who obtains a controlling interest in CoreStates Common 
Shares and thereby could impede a change in control of CoreStates. CoreStates 
has agreed in the Meridian/CoreStates Merger Agreement to fix the size of its 
Board of Directors at 15 members, comprised of ten of the current directors 
of CoreStates and five of the current directors of Meridian. See "CERTAIN 
INFORMATION REGARDING PENDING MERIDIAN/CORESTATES MERGER -- Management and 
Operations After the Meridian/CoreStates Merger." 

   Preemptive Rights. The holders of CoreStates Common Stock have no 
preemptive rights to acquire any new or additional unissued shares or 
treasury shares of CoreStates capital stock. 

   Liquidation Rights. In the event of a liquidation, dissolution or winding 
up of CoreStates, whether voluntary or involuntary, the holders of CoreStates 
Common Stock will be entitled to share ratably in any of CoreStates' assets 
or funds that are available for distribution to its shareholders after the 
satisfaction of its labilities (or after adequate provision is made therefor) 
and after preferences on any outstanding preferred stock. 

   Assessment and Redemption. The shares of CoreStates Common Stock issuable 
pursuant to the Meridian/CoreStates Merger will be, when issued, fully paid 
and nonassessable. CoreStates Common Stock does not have any redemption 
provisions.

CORESTATES SERIES PREFERRED STOCK 

   CoreStates' Articles of Incorporation contain general terms for Series 
Preferred Stock, and specific terms for a series of 3,041,000 shares 
designated as Series A Preferred Stock with a stated value of $25 per share. 
No shares of Series Preferred Stock or Series A Preferred Stock are issued or 
outstanding. 

   Dividend Rights. The holders of Series A Preferred Stock are entitled to 
receive out of any funds legally available therefor, when and as declared by 
CoreStates' Board of Directors, cash dividends at an annual per share rate 
equal to 12.3%. 

   Voting Rights. Except as otherwise required by law or as provided in any 
resolution of the CoreStates Board of Directors designating a series of 
Series Preferred Stock (a "Creating Resolution"), any series of Series 
Preferred Stock has no voting rights and shall not be entitled to notice of 
any meeting of the shareholders of CoreStates. Except as otherwise provided 
by law or in any Creating Resolution, upon any matter on which the shares of 
Series Preferred Stock of any series have voting rights, each holder of 
shares of Series Preferred Stock of such series shall be entitled to one vote 
for each $25 which would be payable with respect to the holder's shares of 
Series Preferred Stock of such series upon any involuntary liquidation, 
dissolution or winding up of CoreStates. The Creating Resolution relating to 
the Series A Preferred Stock did not provide for any voting rights or notice 
of any meeting of the shareholders of CoreStates. Except as otherwise 
provided in a Creating Resolution, in the event that dividends upon any 
series of the Series Preferred Stock shall be in arrears in an amount equal 
to six full quarterly dividends thereon, the holders of such series shall 
become entitled to vote noncumulatively at all elections of directors of 
CoreStates, and to receive notice of all shareholders' meetings to be held 
for such purpose. At such meetings, the holders of such series, voting as a 
class together with the holders of any other series then having the right to 
elect directors under such circumstances, shall be entitled solely to elect 
two members of the Board of Directors of CoreStates and all other directors 
of CoreStates shall be elected by the other shareholders of CoreStates 
entitled to vote in the election of directors. Such voting rights of the 
holders of such series shall continue until all accumulated and unpaid 
dividends thereon shall have been paid or funds sufficient therefor set 
aside, whereupon all such voting rights of the holders of shares of such 
series shall cease, subject to being revived from time to time upon the 
reoccurrence of the conditions above described as giving rise thereto. 

   At any time when such right to elect directors separately as a class has 
so vested, CoreStates may, and upon written request of the holders of record 
of not less than 20% of the then outstanding total number of shares of all 
the Series Preferred Stock having the right to elect directors in such 
circumstances shall, call a special meeting of holders of such Series 
Preferred Stock for the election of directors. Upon the mailing of the notice 
of such special meeting to the holders of such Series Preferred Stock, or, if 
no such meeting is held, then upon the mailing of the notice of the next 
annual or special meeting of shareholders for the election of directors, the 
number of directors of CoreStates shall be increased only to the extent 
necessary to provide sufficient vacancies to enable the holders of such 
Series Preferred Stock to elect the two directors discussed herein, and all 
such vacancies shall be filled only by a vote of the holders of such Series 
Preferred Stock as discussed herein. Whenever the number of directors of 
CoreStates shall have been increased, the number as so increased may 
thereafter be further increased or decreased in such manner as may be 
permitted by CoreStates' By-laws and without the vote of the holders of 
Series Preferred Stock, provided that no such action shall impair the right 
of the holders of Series Preferred Stock to elect and to be represented by 
two directors as herein discussed. 

   So long as the holders of any series of Series Preferred Stock are 
entitled to voting rights under the Articles of Incorporation of CoreStates, 
any vacancy in the Board of Directors caused by the death or resignation of 
any director elected by the holders of Series Preferred Stock, shall, until 
the next meeting of shareholders for the election of directors, in each case 
be filled by the remaining director elected by the holders of Series 
Preferred Stock having the right to elect directors in such circumstances. 

   Upon termination of the voting rights of the holders of any series of 
Series Preferred Stock, so long as no other Series of Preferred Stock then 
outstanding has the right to elect directors in such circumstances, the terms 
of the office of all persons who shall have been elected directors of 
CoreStates by vote of the holders of Series Preferred Stock or by a director 
elected by such holders shall forthwith terminate. 

   Except in certain cases, as long as two or more series of Series Preferred 
Stock are outstanding, no particular series of Series Preferred Stock shall 
be entitled to vote as a separate series on any matter and all shares of 

                                      43 

<PAGE>
Series Preferred Stock of all series shall be deemed to constitute but one 
class for any purpose for which a vote of the shareholders of CoreStates by 
classes may now or hereafter be required. 

   Preemptive Rights. No holder of Series Preferred Stock shall have any 
preemptive right to acquire any new or additional unissued shares or treasury 
shares of CoreStates capital stock. 

   Liquidation Rights. In the event of a liquidation, dissolution or winding 
up of CoreStates, whether voluntary or involuntary, the holders of Series A 
Preferred Stock shall be entitled only to payment in cash of $25 per share, 
plus an amount equal to full cumulative dividends to the date when such 
payments shall be made available to the holders thereof. 

   Redemption. The Series A Preferred Stock may be called for redemption and 
redeemed by the payment therefor of $25 per share, plus an amount equal to 
full cumulative dividends to the date fixed by the Board of Directors as such 
redemption date. 

   Certain Corporate Action. Without the consent of the holders of at least a 
majority of the shares of Series Preferred Stock at the time outstanding, 
CoreStates cannot (i) authorize any new class or series of shares or any 
series of Series Preferred Stock, or an increase in the authorized amount of 
any class or series of shares or any series of Series Preferred Stock, which 
shall rank senior to any series of the Series Preferred Stock with respect to 
payment of dividends or distribution upon liquidation; provided, however, 
that if shares of such class or series would rank prior to one or more but 
not all the several series of the Series Preferred Stock at the time 
outstanding, the consent of the holders of a majority of the shares of all 
series with respect to which shares of such class or series would rank prior 
shall be required in lieu of the consent of holders of all Series Preferred 
Stock; or (ii) increase the authorized Series Preferred Stock to any amount 
in excess of 5,000,000 shares; or (iii) merge or consolidate with any other 
corporation if the corporation resulting from such merger or consolidation 
would have after such merger or consolidation any authorized class of shares 
ranking prior to or equal with the Series Preferred Stock with respect to 
payment of dividends or distributions upon liquidation, except for classes 
having the same number of shares with the same rights and preferences as the 
authorized shares of CoreStates immediately preceding such merger or 
consolidation.

Articles of Incorporation or Bylaws," for a description of the manner in 
which CoreStates' Articles of Incorporation and By-laws may be amended. 
    

                       COMPARISON OF SHAREHOLDER RIGHTS 

GENERAL 

   Meridian and CoreStates are each Pennsylvania corporations subject to the 
provisions of the PaBCL. UCB is a New Jersey corporation subject to the 
provisions of the New Jersey Business Corporation Act ("NJBCA"). Stockholders 
of UCB, whose rights are governed by UCB's Certificate of Incorporation and 
Bylaws and the NJBCA will, upon completion of the Merger, become shareholders 
of Meridian and, on the Effective Date, their rights as shareholders of 
Meridian will be determined by Meridian's Articles of Incorporation, 
Meridian's Bylaws and the PaBCL. If both the Merger and the 
Meridian/CoreStates Merger are completed, stockholders of UCB will ultimately 
become shareholders of CoreStates and their rights as shareholders of 
CoreStates will be determined by the PaBCL, CoreStates' Articles of 
Incorporation and CoreStates' Bylaws. 

   The rights of a holder of UCB Common Stock are similar in some respects 
and different in other respects from the rights of a holder of Meridian 
Common Stock or CoreStates Common Stock. The following summarizes certain 
similarities and differences but does not purport to be a complete 
description of the similarities and differences between the rights of holders 
of the common stock of UCB, Meridian and CoreStates. Such differences may be 
determined in full by reference to New Jersey law, Pennsylvania law, UCB's 
Certificate of Incorporation and Bylaws, Meridian's Articles of Incorporation 
and Bylaws and CoreStates' Articles of Incorporation and Bylaws. The 
information related to CoreStates will be applicable to UCB stockholders only 
if the Merger and the Meridian/CoreStates Merger are completed.

   The following discussion does not purport to be a complete discussion of, 
and is qualified in its entirety by reference to, the governing law and the 
Articles or Certificate of Incorporation and Bylaws of each corporation. 

AUTHORIZED CAPITAL 

   Meridian's Articles of Incorporation authorize the issuance of 200,000,000 
shares of Meridian Common Stock, par value $5.00 per share, and 25,000,000 
shares of preferred stock, par value $25.00 per share. As of September 30, 
1995, there were 57,822,604 shares of Meridian Common Stock and no shares of 
Meridian Preferred Stock issued and outstanding. See "DESCRIPTION OF MERIDIAN 
CAPITAL SECURITIES" in the accompanying Proxy Statement/Prospectus. 

   CoreStates' Articles of Incorporation authorize the issuance of 
200,000,000 shares of CoreStates Common Stock, par value $1.00 per share, and 
10,000,000 shares of Series Preferred Stock, without par value. As of 
November 1, 1995, there were 139,152,444 shares of CoreStates Common Stock 
issued and outstanding and no shares of Series Preferred Stock issued and 
outstanding. 

   
   UCB's Certificate of Incorporation authorizes the issuance of 6,000,000 
shares of UCB Common Stock, no par value $1.00 stated value per share, and 
3,000,000 shares of preferred stock, no par value (the "UCB Preferred 
Stock"). As of the Record Date, there were 2,148,150 shares of UCB Common 
Stock and no shares of UCB Preferred Stock issued and outstanding. UCB 
Preferred Stock is issuable in series, each having such rights, and 
preferences as the Board of Directors of UCB may, by adoption of an amendment 
of UCB's Certificate of Incorporation, fix and determine. 
    

DIRECTORS 

  REMOVAL 

   Pursuant to Meridian's Articles of Incorporation, Meridian directors may 
be removed from office without cause by the affirmative vote of a majority of 
outstanding voting shares. 

   Under CoreStates' Bylaws and Pennsylvania law, directors may only be 
removed for cause. In case the Board of Directors or a class of the Board of 
Directors or any one or more directors are so removed, new directors may be 
elected at the same meeting. 

   UCB's Certificate of Incorporation does not provide for the removal of 
directors. However, pursuant to the NJBCA, one or more UCB directors may be 
removed without cause by the affirmative vote of the majority of votes cast 
by stockholders entitled to vote for the election of directors. 

 NOMINATION 

   Meridian's Bylaws provide that nominations for the election of directors 
may be made by the Board of Directors or any shareholder entitled to vote for 
the election of directors. Written notice of a shareholder's intent to 
nominate a director at the meeting must be given by the shareholder and 
received by the Secretary of Meridian not less than 30 days nor more than 50 
days prior to the date of the annual meeting of shareholders. However, if 
less than 21 days' notice of the meeting is given to shareholders, written 
notice of a shareholder's intent to nominate a director is required to be 
delivered to the Secretary of Meridian not later than the seventh day 
following the day on which notice of the meeting was first mailed to 
shareholders. The notice is required to be in writing and contain or be 
accompanied by certain information about such shareholder, as described in 
Meridian's Bylaws. The chairman of the meeting may, if the facts warrant, 
determine and declare to the meeting that any nomination made at the meeting 
was not made in accordance with the foregoing procedures and, in such event, 
the nomination will be disregarded. 

   CoreStates' Bylaws provide that nominations for election of directors may 
be made by any shareholder entitled to vote for the election of directors so 
long as written notice of such shareholder's intent to nominate a director at 
the meeting is given by the shareholder and received by the Secretary of 
CoreStates not less than 45 days prior to the date of the annual meeting of 
shareholders. If directors are to be elected by shareholders at any other 
time, notice is required to be delivered to the Secretary of CoreStates not 
later than the seventh day following the date on which notice of the 

                                      45 

<PAGE>

meeting was first mailed to shareholders. In lieu of delivery to the Secretary
of CoreStates, such notice may be mailed to the Secretary of CoreStates
certified mail, return receipt requested, but shall be deemed to have been given
only upon actual receipt by the Secretary of CoreStates. The notice is required
to be in writing and contain or be accompanied by certain information about such
shareholder, as described in CoreStates Bylaws. The chairman of the meeting may,
if the facts warrant, determine and declare to the meeting that any nomination
made at the meeting was not made in accordance with the foregoing procedures
and, in such event, the nomination will be disregarded.

   Neither the Certificate of Incorporation or Bylaws of UCB nor the NJBCA 
sets forth the procedures pursuant to which UCB shareholders may nominate a 
candidate for election as a director. 

 ELECTION OF DIRECTORS 

   Meridian's Articles of Incorporation and Bylaws provide that the Meridian 
Board of Directors shall be composed of not less than 12 nor more than 24 
directors, the number of which may be determined by the Meridian Board of 
Directors. Currently, the Meridian Board of Directors is composed of 24 
members. The Meridian Board of Directors is divided into three classes, each 
serving three-year terms, so that approximately one-third of the directors of 
Meridian are elected at each annual meeting of shareholders of Meridian. 
Classification of the Meridian Board of Directors has the effect of 
decreasing the number of directors that could be elected in a single year by 
any person who seeks to elect its designees to a majority of the seats on the 
Meridian Board of Directors and thereby could impede a change in control of 
Meridian. 

   CoreStates' Articles of Incorporation provide for a classified Board of 
Directors, consisting of three substantially equal classes of directors, each 
serving for a three-year term, with the term of each class of directors 
ending in successive years. The CoreStates Board of Directors currently 
consists of 17 members. See "CERTAIN INFORMATION REGARDING PENDING 
MERIDIAN/CORESTATES MERGER -- Management and Operations After the 
Meridian/CoreStates Merger. Classification of the CoreStates Board may have 
the effect of decreasing the number of directors that could otherwise be 
elected at a given annual meeting by anyone who obtains a controlling 
interest in CoreStates Common Stock and thereby could impede a change in 
control of CoreStates. 

   UCB's Bylaws provide that the UCB Board of Directors shall be composed of 
not less than 5 nor more than 25 directors, the number of which may be 
determined by the UCB Board of Directors. Currently, the UCB Board of 
Directors is composed of six members. UCB's Board of Directors is not 
classified. All directors of UCB are elected at each annual meeting of 
shareholders of UCB. Therefore, any person who seeks to elect its designees 
to a majority of the seats on the UCB Board of Directors could do so at any 
annual meeting. 

 CUMULATIVE VOTING 

   Neither Meridian's, CoreStates' nor UCB's shareholders are permitted to 
cumulate votes in the election of directors. 

 LIMITED LIABILITY 

   As permitted by the PaBCL, Meridian's Bylaws provide that directors of 
Meridian are not personally liable for taking or failing to take any action 
unless the director breached or failed to perform the duties of his or her 
office as set forth under Pennsylvania law and such breach or failure 
constitutes self-dealing, willful misconduct or recklessness; provided, 
however, that there is no such elimination of liability arising under any 
criminal statute or with respect to the payment of taxes pursuant to local, 
state or federal law. 

   As permitted by the PaBCL, CoreStates' Articles of Incorporation and 
CoreStates' Bylaws provide that a director or officer shall not be personally 
liable, as such, for monetary damages for any action taken, or any failure to 
take any action, unless the director or officer has breached or failed to 
perform the duties of his or her office and the breach or failure to perform 
constitutes self-dealing, willful misconduct or recklessness. Such limitation 
(i) does not apply to the responsibility or liability of a director or 
officer pursuant to any criminal statute or the liability of a director or 
officer for the payment of taxes, and (ii) may, in the view of certain 
commentators, shield a director from liability for certain breaches of his or 
her duty of loyalty as well as his or her duty of care. 

                                      46 

<PAGE>
   As permitted by the NJBCA, UCB's Certificate of Incorporation provides 
that directors of UCB are not personally liable for breach of any duty owed 
to UCB or its shareholders, unless such breach of duty is the result of an 
act or omission (i) in breach of such director's duty of loyalty to UCB or 
its shareholders, (ii) not in good faith or involving a knowing violation of 
law, or (iii) resulting in receipt by such person of an improper personal 
benefit. 

 INDEMNIFICATION 

   As permitted by the PaBCL, Meridian's Bylaws provide for indemnification 
of directors, officers and agents for certain litigation-related liabilities 
and expenses unless the individual's conduct is determined by a court to have 
constituted willful misconduct or reckless conduct. 

   In accordance with the PaBCL, and pursuant to its Bylaws, CoreStates is 
obligated to indemnify an Indemnified representative (as defined below) 
against any Liability (as defined below) incurred in connection with any 
Proceeding (as defined below) in which the Indemnified representative may be 
involved as a party or otherwise, by reason of the fact that such person is 
or was serving in an Indemnified capacity (as defined below), including, 
without limitation, liabilities resulting from any actual or alleged breach 
or neglect of duty, error, misstatement or misleading statement, negligence, 
gross negligence or act giving rise to strict or product Liabilities; except: 

   1. where such indemnification is expressly prohibited by applicable law, 
or 

   2. where the conduct of the Indemnified representative has been determined 
to constitute willful misconduct or recklessness within the meaning of 42 
Pa.C.S. Section8365(b) (now a reference to PaBCL Section1746(b) or any 
superseding provision of law, sufficient in the circumstances to bar 
indemnification against Liabilities arising from the conduct. 

   For purposes of the foregoing, 

   "Indemnified capacity" means any and all past, present and future service 
by an indemnified representative in one or more capacities as a director, 
officer, employee or agent of CoreStates, or, at the request of CoreStates, 
as a director, officer, employee, agent, fiduciary or trustee of another 
corporation, partnership, joint venture, trust, employee benefit plan or 
other entity or enterprise; 

   "Indemnified representative" means any and all directors and officers of 
the corporation and any other person designated as an indemnified 
representative by the Board of Directors of CoreStates (which may, but need 
not, include any person serving at the request of CoreStates, as a director, 
officer, employee, agent, fiduciary or trustee of another corporation, 
partnership, joint venture, trust, employee benefit plan or other entity or 
enterprise); 

   "Liability" means any damage, judgment, amount paid in settlement, fine, 
penalty, punitive damages, excise tax assessed with respect to an employee 
benefit plan, or other cost or expense of any nature (including, without 
limitation, attorneys' fees and disbursements); and 

   "Proceeding" means any threatened, pending or completed action, suit, 
appeal or other proceeding of any nature, whether civil, criminal, 
administrative or investigative, whether formal or informal, and whether 
brought by or in the right of CoreStates, a class of its security holders or 
otherwise. 

   As permitted by the NJBCA, UCB's Certificate of Incorporation provides for 
indemnification of directors, officers, employees and agents of UCB, and any 
other person serving in such capacity with any other entity at the request of 
UCB, for certain litigation-related liabilities and expenses to the full 
extent permitted under the NJBCA. 

SHAREHOLDERS' MEETINGS 

   Meridian's Bylaws provide that the Board of Directors may fix the date and 
time of the annual meeting of shareholders, but if no such date is fixed, the 
meeting for any calendar year is to be held on the third Tuesday of April in 
such year. Notice of the annual meeting of shareholders must be given not 
less than 10 days before the date of the meeting. The presence, in person or 
by proxy, of shareholders entitled to cast at least 66 2/3% of the votes

                                      47 

<PAGE>

that all shareholders are entitled to cast constitutes a quorum for the
transaction of business at the meeting. Meridian's Bylaws provide that special
meetings of shareholders may be called at any time by any of the following: (1)
the Chief Executive Officer, Chairman or President of Meridian; (2) the Board of
Directors of Meridian or the Executive Committee thereof; or (3) Meridian
shareholders entitled to cast at least 20% of the votes which all shareholders
are entitled to cast at the meeting. Notice of special meetings of shareholders
must be given not less than 10 days before the date of the meeting.

   CoreStates Bylaws provide that the Board of Directors may fix and 
designate the date and time of the annual meeting of shareholders, but if no 
such date is fixed, the meeting for any calendar year is to be held on the 
third Tuesday of April in such year. The presence in person or by proxy of 
shareholders entitled to cast at least a majority of the votes that all 
shareholders are entitled to cast on a particular matter to be acted upon at 
the meeting constitutes a quorum at that meeting. CoreStates Bylaws provide 
that a special meeting of the shareholders may be called at any time by the 
Chairman of the Board, the President, or the Board of Directors, who may fix 
the date, time and place of the meeting. If the date, time or place of the 
meeting is not so fixed, it will be fixed by the Secretary. A date fixed by 
the secretary cannot be more than 60 days after the date of the calling of 
the meeting. CoreStates' Bylaws expressly provide that, except when acting by 
unanimous consent to remove a director or directors, shareholders may act 
only at a duly organized meeting. 

   UCB's Bylaws provide that the Board of Directors may fix the date and time 
of the annual meeting of shareholders. Notice of the annual meeting of 
shareholders must be given not less than 10 days nor more than 60 days prior 
to the date of the meeting. The presence, in person or by proxy, of a 
majority of the outstanding voting shares constitutes a quorum for the 
transaction of business at the meeting. A special meeting of UCB's 
shareholders may be called at any time by any of the following: (1) the 
Chairman or President of UCB, or (2) a majority of the Board of Directors. 
The NJBCA provides that holders of 10% or more of all the shares entitled to 
vote may apply to the Superior Court of New Jersey to order that a special 
meeting of shareholders be held. Notice of a special meeting of shareholders 
must be given not less than 10 nor more than 60 days prior to the date of the 
meeting. 

   Meridian's Bylaws set forth procedures pursuant to which any business, 
including the nomination of directors by a shareholder, may be properly 
brought by a shareholder before an annual meeting of shareholders. Core- 
States' Bylaws set forth procedures pursuant to which shareholders may submit 
nominations for the election of directors, but neither its Bylaws nor its 
Articles of Incorporation set forth procedures pursuant to which other 
businesses may be properly brought by a shareholder before an annual meeting 
of shareholders. Neither UCB's Bylaws nor its Certificate of Incorporation 
set forth similar procedures pursuant to which business, including the 
nomination of directors by a shareholder, may be brought before an annual 
meeting of shareholders. 

SHAREHOLDER RIGHTS PLAN 

   Meridian has adopted a shareholder rights plan pursuant to which holders 
of Meridian Common Stock are entitled, under certain circumstances generally 
involving an accumulation of Meridian Common Stock, to purchase Meridian 
Common Stock or common stock of the potential acquiror at a substantially 
reduced price. See "DESCRIPTION OF MERIDIAN CAPITAL SECURITIES -- Shareholder 
Rights Plan" in the accompanying Proxy Statement/Prospectus. On October 10, 
1995, Meridian amended its shareholder rights plan so that such plan would 
not be triggered by the execution of the Meridian/CoreStates Merger Agreement 
or the Meridian Stock Option Agreement or completion of the transactions 
contemplated thereby. Neither CoreStates nor UCB has adopted a shareholder 
rights plan. 

ANTITAKEOVER PROVISIONS 

   Meridian and CoreStates are each subject to some, but not all, of various 
provisions of the PaBCL which are triggered, in general, if any person or 
group acquires, or discloses an intent to acquire, 20% or more of the voting 
power of a covered corporation, other than pursuant to a registered firm 
commitment underwriting or, in certain cases, pursuant to the approving vote 
of the board of directors. The relevant provisions are contained in 
Subchapters 25E-H of the PaBCL. 

   Subchapter 25E of the PaBCL (relating to control transactions) provides 
that if any person or group acquires 20% or more of the voting power of a 
covered corporation, the remaining shareholders may demand from such person 
or group the fair value of their shares, including a proportionate amount of 
any control premium. 

                                      48 

<PAGE>
   Subchapter 25F of the PaBCL (relating to business combinations) delays for 
five years and imposes conditions upon "business combinations" between an 
"interested shareholder" and the corporation. The term "business combination" 
is defined broadly to include various transactions utilizing a corporation's 
assets for purchase price amortization or refinancing purposes. For this 
purpose, an "interested shareholder" is defined generally as the beneficial 
owner of at least 20% of a corporation's voting shares. 

   Subchapter 25G of the PaBCL (relating to control-share acquisitions) 
prevents a person who has acquired 20% or more of the voting power of a 
covered corporation from voting such shares unless the "disinterested" 
shareholders approve such voting rights. Failure to obtain such approval 
exposes the owner to the risk of a forced sale of the shares to the issuer. 
Even if shareholder approval is obtained, the corporation is also subject to 
Subchapters 25I and J of the PaBCL. Subchapter 25I provides for a minimum 
severance payment to certain employees terminated within two years of the 
approval. Subchapter 25J prohibits the abrogation of certain labor contracts 
prior to their stated date of expiration. 

   Subchapter 25H of the PaBCL (relating to disgorgement) applies in the 
event that (i) any person or group publicly discloses that the person or 
group may acquire control of the corporation or (ii) a person or group 
acquires (or publicly discloses an offer or intent to acquire) 20% or more of 
the voting power of the corporation and, in either case, sells shares within 
18 months thereafter. Any profits from sales of equity securities of the 
corporation by the person or group during the 18-month period belong to the 
corporation if the securities that were sold were acquired during the 
18-month period or within 24 months prior thereto. 

   Subchapters 25E-H of the PaBCL contain a wide variety of transactional and 
status exemptions, exclusions and safe harbors. As permitted under the PaBCL, 
Meridian and CoreStates have each opted out of the provisions of Subchapters 
25G and H but are subject to the provisions of Subchapters 25E and F. Such 
action can be reversed under certain circumstances. 

   In addition, the fiduciary duty standards applicable to the Board of 
Directors of each of Meridian and CoreStates under the PaBCL may have the 
effect of deterring or discouraging, among other things, a nonnegotiated 
tender or exchange offer for Meridian or CoreStates stock, a proxy contest 
for control of Meridian or CoreStates, the assumption of control of Meridian 
or CoreStates by a holder of a large block of Meridian's or CoreStates' 
stock, respectively, and the removal of Meridian's or CoreStates' management. 
See "DESCRIPTION OF MERIDIAN CAPITAL SECURITIES -- Special Charter and 
Pennsylvania Corporation Law Provisions" in the accompanying Proxy 
Statement/Prospectus. 

   Under a provision of the Pennsylvania Banking Code of 1965 designed to 
protect shareholders of Pennsylvania banking institutions, subject to certain 
exceptions, no person may offer to acquire, or acquire, control of more than 
10% of the outstanding shares of a Pennsylvania banking institution or 5% of 
the outstanding shares of a Pennsylvania banking institution if such 
institution had net operating loss carry forwards in excess of 20% of its 
total shareholders' equity as reported in its most recent publicly available 
annual financial statements, without the prior written approval of the 
Pennsylvania Department of Banking. 

   The New Jersey Shareholders Protection Act ("NJSPA") provides that no 
corporation organized under the laws of New Jersey with its principal 
executive offices or significant operations located in New Jersey (a "New 
Jersey Resident Domestic Corporation") may engage in any "business 
combination" (as defined in the NJSPA, a "Business Combination") with any 
interested shareholder (as defined in the NJSPA, an "Interested Stockholder") 
of that New Jersey Resident Domestic Corporation for a period of five years 
following that Interested Stockholder's stock acquisition unless that 
Business Combination is approved by the board of directors of that New Jersey 
Resident Domestic Corporation prior to that Interested Stockholder's stock 
acquisition. The term Business Combination as defined in the NJSPA includes, 
among other things, certain mergers, consolidations, asset transfers, stock 
issuances, plans of liquidation and recapitalizations. Interested 
Stockholder, as defined in the NJSPA, includes certain holders of 10% or more 
of the voting power of the outstanding voting stock of that New Jersey 
Resident Domestic Corporation and certain affiliates of the New Jersey 
Resident Domestic Corporation that at any time within the five year period 
immediately prior to the date in question were the beneficial owners, 
directly or indirectly, of 10% or more of the voting power of the then 
outstanding stock of the New Jersey Resident Domestic Corporation. 

   Pursuant to the NJSPA, no New Jersey Resident Domestic Corporation may 
engage, at any time, in any Business Combination with any Interested 
Stockholder of that New Jersey Resident Domestic Corporation other 

                                      49 

<PAGE>
than: (i) a Business Combination approved by the board of directors of that 
New Jersey Resident Domestic Corporation prior to that Interested 
Stockholder's stock acquisition, (ii) a Business Combination approved by the 
affirmative vote of the holders of two-thirds of the voting stock not 
beneficially owned by that Interested Stockholder at a meeting called for 
such purpose, or (iii) a Business Combination where the Interested 
Stockholder pays a formula price designed to ensure that all holders (other 
than the Interested Stockholder) of stock of the New Jersey Resident Domestic 
Corporation receive at least the highest price per share paid by that 
Interested Stockholder. The NJSPA does not apply to certain inadvertent 
acquisitions, provided the shareholder divests itself or himself of a 
sufficient number of shares in accordance with the NJSPA. A New Jersey 
Resident Domestic Corporation may not opt-out of the NJSPA. 

   Under the NJBCA, the director of a New Jersey corporation may consider, in 
discharging his or her duties to the corporation and in determining what he 
or she reasonably believes to be in the best interests of the corporation, 
any of the following (in addition to the effects of any action on 
shareholders): (i) the effects of the action on the corporation's employees, 
suppliers, creditors and customers, (ii) the effects of the action on the 
community in which the corporation operates and (iii) the long-term as well 
as the short-term interests of the corporation and its shareholders, 
including the possibility that these interests may be best served by the 
continued independence of the corporation. If, on the basis of the foregoing 
factors, the board of directors determines that any proposal or offer to 
acquire the corporation is not in the best interests of the corporation, it 
may reject such proposal or offer, in which event the board of directors will 
have no duty to remove any obstacles to, or refrain from impeding, such 
proposal or offer. 

REQUIRED SHAREHOLDER VOTE 

 GENERAL 

   Subject to the voting rights of any series of Meridian Preferred Stock 
then outstanding, the holders of Meridian Common Stock possess exclusive 
voting rights of Meridian. Each holder of Meridian Common Stock is entitled 
to one vote for each share owned of record. There are no cumulative voting 
rights in the election of directors. For general corporate action of the 
shareholders of Meridian, the affirmative vote of a majority of the votes 
cast in person or by proxy at a shareholders' meeting is required for 
approval. 

   Subject to the voting rights of any series of CoreStates Series Preferred 
Stock then outstanding, the holders of CoreStates Common Stock possess 
exclusive voting rights of CoreStates. Each holder of CoreStates Common Stock 
is entitled to one vote for each share owned of record. There are no 
cumulative voting rights in the election of directors. For general corporate 
action of the shareholders of CoreStates, the affirmative vote of a majority 
of the votes cast in person or by proxy at a shareholders' meeting at which a 
quorum is present is required for approval. 

   Subject to the voting rights of any series of UCB Preferred Stock then 
outstanding, the holders of UCB Common Stock possess exclusive voting rights 
of UCB. Each holder of UCB Common Stock is entitled to one vote for each 
share owned of record. There are no cumulative voting rights in the election 
of directors. For general corporate actions submitted to the shareholders of 
UCB, the affirmative vote of a majority of votes cast at any shareholders' 
meeting is required for approval. 

 FUNDAMENTAL CHANGES 

   Meridian's Articles of Incorporation require that a plan of merger, 
consolidation, share exchange, division, conversion or transfer of all, or 
substantially all, the assets of Meridian (other than in the usual and 
regular course of business) must be approved by the affirmative vote of 
shareholders entitled to cast at least a majority of the votes which all 
shareholders are entitled to cast. In the absence of prior approval by 
Meridian's Board of Directors, Meridian's Articles of Incorporation require a 
vote of shareholders with at least 80% of Meridian's total voting power to 
approve any merger, consolidation, share exchange, asset transfer (in respect 
of a sale, lease, exchange or other disposition of all, or substantially all, 
the assets of Meridian) or similar transactions involving a shareholder 
holding 5% or more of Meridian's voting power. 

   CoreStates Articles of Incorporation and Bylaws do not contain similar 
provisions with respect to business combinations. However, under the PaBCL, 
applicable to CoreStates, a plan of merger, consolidation, share 

                                      50 

<PAGE>
   
exchange, division, conversion or asset transfer (in respect of a sale, 
lease, exchange or other disposition of all, or substantially all, the assets 
of a corporation other than in the usual and regular course of business) 
generally must be proposed by the board of directors and approved by the 
affirmative vote of a majority of the votes cast by all shareholders of any 
class or series of shares entitled to vote thereon as a class. 
    

   The PaBCL also provides that if a shareholder of a registered corporation 
is a party to a sale of assets transaction, share exchange, merger or 
consolidation involving the corporation or a subsidiary, or if a shareholder 
is to receive a disproportionate amount of the shares or other securities of 
any corporation surviving or resulting from a plan of division, or is to be 
treated differently in a corporate dissolution from other shareholders of the 
same class, or is to have a materially increased percentage of voting or 
economic share interest in the corporation relative to substantially all 
other shareholders as a result of a reclassification, then approval must be 
obtained of the shareholders entitled to cast at least a majority of the 
votes which all shareholders other than the interested shareholder are 
entitled to cast with respect to the transaction, without counting the votes 
of the interested shareholder (and certain affiliated and associated 
persons). Such additional shareholder approval is not required if the 
consideration to be received by the other shareholders in such transaction 
for shares of any class is not less than the highest amount paid by the 
interested shareholder in acquiring shares of the same class, or if the 
proposed transaction is approved by a majority of the board of directors 
other than certain directors affiliated or associated with, or nominated by, 
the interested shareholder. 

   Under the PaBCL, an articles amendment or plan of reclassification, 
merger, consolidation, exchange, asset transfer, division or conversion that 
provides mandatory special treatment for the shares of a class held by 
particular shareholders or groups of shareholders that differs materially 
from the treatment accorded other shareholders or groups of shareholders 
holding shares of the same class must be approved by each group of holders of 
any outstanding shares of a class who are to receive the same special 
treatment under the amendment or plan, voting as a special class in respect 
of the plan, regardless of any limitations stated in the articles or bylaws 
on the voting rights of any class or series. At the option of the 
corporation's board of directors, the approval of such special treatment by 
any such affected group may be omitted, but in such event the holder of any 
outstanding shares of the special class so denied voting rights will be 
entitled to dissenters' rights (i.e., the right to demand payment in cash by 
the corporation of the fair value of the shareholder's shares). 

   UCB's Certificate of Incorporation requires a supermajority vote of 
shareholders to approve business combinations (includes any merger, 
consolidation, or any sale, transfer, or other disposition of all or a 
substantial part of the assets of UCB). For a business combination which has 
been recommended by at least 66 2/3 % of UCB's Board of Directors, the 
affirmative vote of 66 2/3 % of the shares entitled to vote is required for 
approval. For a business combination which has not been recommended by at 
least 66 2/3 % of UCB's Board of Directors, the affirmative vote of 75% of 
the shares entitled to vote is required for approval. 

 AMENDMENT OF ARTICLES OR CERTIFICATE OF INCORPORATION 

   Meridian's Articles of Incorporation contain various provisions that 
require a supermajority vote of shareholders to amend or repeal particular 
sections of such Articles. Amendment or repeal of the provisions of 
Meridian's Articles of Incorporation relating to noncumulative voting, the 
classification of directors, the requirement of holding meetings for 
shareholder action, the amendment of Bylaws generally, and the consideration 
of non-economic factors by Meridian's Board of Directors in evaluating a 
tender offer, all require a 66 2/3 % vote of shareholders, absent prior 
Meridian Board approval. In the case of certain other provisions, including 
the supermajority vote requirement on a merger or similar transaction with a 
5% or greater Meridian shareholder, amendment or repeal requires a vote of 
shareholders owning 80% of Meridian's outstanding shares or a 66 2/3 % vote 
of both Meridian's Board of Directors and its shareholders. 

   CoreStates' Articles of Incorporation may be amended in the manner 
prescribed by the PaBCL. The PaBCL generally provides that an amendment of 
the articles of incorporation must be proposed by the Board of Directors and 
may be adopted by the affirmative vote of a majority of the votes cast by all 
shareholders entitled to vote thereon. Notwithstanding the foregoing, without 
the consent of the holders of at least two-thirds of the shares of Series 
Preferred Stock outstanding, CoreStates cannot adopt or effect any amendment 
to its Articles of Incorporation which would adversely affect the rights or 
preferences of the Series Preferred Stock (except as may be expressly 
permitted under its Articles of Incorporation with the consent of the holders 
of a majority of the shares of Series Preferred Stock); provided, however,

                                      51 

<PAGE>

that if any such amendment adversely affects the rights or preferences of one or
more, but not all, of the series of Series Preferred Stock at the time
outstanding, the consent of the holders of at least two-thirds shares of all
Series Preferred Stock is required.

   The NJBCA provides that a corporation's articles of incorporation may be 
amended upon approval of such corporation's board of directors and the 
affirmative vote of a majority of the votes cast by shareholders entitled to 
vote, subject to any supermajority requirements set forth in such articles of 
incorporation. UCB's Certificate of Incorporation requires the affirmative 
vote of 66 2/3 % of the shares entitled to vote to amend any of the 
provisions set forth in Article VI of UCB's Certificate of Incorporation 
regarding business combinations. 

AMENDMENT OF BYLAWS 

   The authority to amend or repeal Meridian's Bylaws is vested in Meridian's 
Board of Directors, subject always to the power of the shareholders of 
Meridian to change such action by the affirmative vote of shareholders 
holding at least 66 2/3 % of the voting power (except that any amendment to 
the indemnification provisions set forth in the Bylaws requires the 
affirmative vote of 66 2/3 % of the Board of Directors or shareholders 
holding 80% of the voting power). 

   CoreStates Bylaws may be amended by shareholder vote by a majority of the 
votes cast by all shareholders entitled to vote or by a majority of the Board 
of Directors if the matter in question is not required to be submitted to the 
shareholders by statute. 

   UCB's Bylaws may be amended by the Board of Directors of UCB or by the 
affirmative vote of the majority of votes cast by shareholders entitled to 
vote on such amendment. 

MANDATORY TENDER OFFER PROVISION 

   Meridian's Articles of Incorporation provide that any person or entity 
acquiring Meridian capital stock with 25% or more of Meridian's total voting 
power is required to offer to purchase, for cash, all shares of Meridian's 
voting stock, at a price per share equal to the highest price paid by such 
person for each respective class of Meridian's voting stock within the 
preceding twelve months. Neither CoreStates' Articles of Incorporation nor 
UCB's Certificate of Incorporation contain an equivalent provision. The PaBCL 
also provides that following any acquisition by a person or group of more 
than 20% of a publicly-held corporation's voting stock, the remaining 
shareholders have the right to receive payment, in cash, for their shares 
from such person or group of an amount equal to the "fair value" of their 
shares. The NJBCA contains no equivalent provision. 

DISSENTERS' RIGHTS 

   Under the PaBCL, a shareholder of a corporation is generally entitled to 
receive payment for the fair value of such shareholder's shares if such 
shareholder duly exercises its dissenters' rights with respect to a plan of 
merger or consolidation, share exchange or asset transfer, to which such 
corporation is a party, except if the shares are (i) listed on a national 
securities exchange or (ii) held by more than 2,000 shareholders. The 
foregoing market exceptions do not apply, and dissenters' rights generally 
are available in respect of, (i) shares that are not converted solely into 
shares or shares and money in lieu of fractional shares, (ii) shares of any 
preferred or special class unless the shareholders of the class are entitled 
to vote on the plan and such class vote is required for the adoption of the 
plan or to effectuate the transaction and (iii) shares which under the plan 
are treated differently from shares of the same class or series and which are 
not entitled to vote as a special class under PaBCL Section1906(c). The PaBCL 
allows a corporation to provide dissenters' rights notwithstanding the 
statutory exceptions but neither Meridian's nor CoreStates' Articles of 
Incorporation or Bylaws require such optional dissenters' rights. Under the 
PaBCL, if a plan of merger or consolidation, share exchange, asset transfer, 
division or conversion is adopted by the directors only, without any 
shareholder approvals required, the shareholders have no statutory 
dissenters' rights in respect of the plan other than optional dissenters' 
rights, if any. In respect of the Merger and the Meridian/CoreStates Merger, 
no statutory dissenters' rights are applicable and no optional dissenters' 
rights have been granted to shareholders. 

   The NJBCA generally provides for dissenters' rights in connection with any 
merger or consolidation or any sale, lease, exchange, or other disposition of 
all or substantially all of the assets of the corporation not in the 

                                      52 

<PAGE>
usual or ordinary course of business. However, no such rights exist with 
respect to (i) any class or series of shares that is listed on a national 
securities exchange or is held of record by not less than 1,000 holders on 
the record date fixed to determine the shareholders entitled to vote on the 
transaction, or, generally, (ii) any transaction in connection with which the 
shareholders of the corporation will receive only (a) cash, (b) securities 
that, upon consummation of the transaction, will be listed on a national 
securities exchange or held by record by not less than 1,000 holders, or (c) 
cash and such securities. A shareholder of a corporation may also dissent 
from any acquisition of shares owned by such shareholder in connection with 
the acquisition by another New Jersey corporation, in exchange for its 
shares, of all the shares of a class or series of securities of such 
corporation. Any shareholder that perfects dissenters' rights under the NJBCA 
is entitled to receive the "fair value" of such shares as determined either 
by agreement between such shareholder and the corporation or by a court of 
competent jurisdiction. UCB stockholders have no dissenters' rights with 
respect to the Merger and, if the Merger is consummated, would have no 
dissenters' rights, as shareholders of Meridian, with respect to the 
Meridian/CoreStates Merger. 

DIVIDENDS 

   Under the PaBCL, a corporation may pay dividends unless, after giving 
effect thereto, (i) the corporation would be unable to pay its debts as they 
come due in the usual course of business or (ii) the total assets of the 
corporation would be less than the sum of its total liabilities plus the 
amount that would be needed, if the corporation were to be dissolved at the 
time as of which the distribution is measured, to satisfy the preferential 
rights upon dissolution of shareholders whose preferential rights are 
superior to those receiving the distribution. 

   Subject to any restrictions contained in a corporation's certificate of 
incorporation, the NJBCA provides that a corporation may pay dividends 
unless, after giving effect thereto, (i) the corporation would be unable to 
pay its debts as they become due in the usual course of its business or (ii) 
the corporation's total assets would be less than its total liabilities. 
UCB's Certificate of Incorporation provides that no dividends may be paid on 
UCB Common Stock if UCB is in default with respect to any dividend due and 
payable on, or any sinking fund or redemption requirements with respect to, 
any outstanding UCB Preferred Stock. 

VOLUNTARY DISSOLUTION 

   Under the PaBCL and Meridian's Articles of Incorporation, if at least 66 
2/3 % of Meridian's Board of Directors recommends that Meridian be dissolved 
and directs that the question be submitted to a vote at a meeting of 
shareholders, Meridian may be dissolved upon the affirmative vote of a 
majority of the votes cast by all shareholders entitled to vote thereon and, 
if any class of shares is entitled to vote thereon as a class, the 
affirmative vote of a majority of the votes cast in each class vote. If at 
least 66 2/3 % of Meridian's Board of Directors has not recommended that 
Meridian be dissolved, Meridian may be dissolved upon the affirmative vote of 
shareholders entitled to cast at least 80% of the votes which all 
shareholders are entitled to cast. 

   Under the PaBCL, if CoreStates' Board of Directors recommends that 
CoreStates be dissolved and directs that the question be submitted to a vote 
at a meeting of shareholders, CoreStates may be dissolved upon the 
affirmative vote of a majority of the votes cast by all shareholders entitled 
to vote thereon and, if any class of shares is entitled to vote thereon as a 
class, the affirmative vote of a majority of the votes cast in each class 
vote. 

   Under the NJBCA, UCB may be dissolved upon the consent of all its 
shareholders entitled to vote thereon or, alternatively, if the UCB Board 
recommends that UCB be dissolved and directs that the question be submitted 
to a vote at a meeting of shareholders, UCB may be dissolved upon the 
affirmative vote of a majority of the votes cast by the shareholders entitled 
to vote thereon and, if any class or series of securities of UCB is entitled 
to vote on such motion as a class, upon the affirmative vote of a majority of 
the votes cast by each such class. If the dissolution is proposed by, on 
behalf of or pursuant to any agreement, arrangement or understanding with an 
Interested Stockholder, the NJSPA will apply. See "Antitakeover Provisions" 
above. 

PREEMPTIVE RIGHTS 

   Neither the holders of Meridian Common Stock, CoreStates Common Stock, nor 
UCB Common Stock are entitled to preemptive rights.

                   UPDATED OPINION OF GOLDMAN, SACHS & CO.

<PAGE>
                  [LETTERHEAD OF GOLDMAN SACHS & CO., INC.] 


   
January 4, 1996 

Board of Directors 
United Counties Bancorporation 
Four Commerce Drive 
Cranford, New Jersey 07016 

Gentlemen: 

You have requested our opinion as to the fairness to the holders of the 
outstanding shares of Common Stock, no par value (the "Shares"), of United 
Counties Bancorporation (the "Company") of the exchange ratio of 5.0 shares 
of Common Stock, par value $5.00 per share ("Meridian Common Stock"), of 
Meridian Bancorp, Inc. ("Meridian") to be received for each Share (the 
"Exchange Ratio") pursuant to the Agreement and Plan of Merger dated as of 
May 23, 1995 between Meridian and the Company (the "Agreement"). 

Goldman, Sachs & Co. ("Goldman Sachs"), as part of its investment banking 
business, is continually engaged in the valuation of businesses and their 
securities in connection with mergers and acquisitions, negotiated 
underwritings, competitive biddings, secondary distributions of listed and 
unlisted securities, private placements and valuations for estate, corporate 
and other purposes. We are familiar with the Company, having acted as its 
financial advisor in connection with, and having participated in certain of 
the negotiations leading to, the Agreement. We also regularly provide 
investment banking and financial advisory services to Meridian, including 
having acted as its financial advisor in connection with its proposed merger 
(the "Meridian/CoreStates Merger") with CoreStates Financial Corp. 
("CoreStates") pursuant to the Agreement and Plan of Merger, dated as of 
October 10, 1995 (the "Meridian/CoreStates Agreement"), its acquisition of 
Commonwealth Bancshares Corporation in 1993, its disposition of Meridian 
Title Insurance Co. in 1992 and its disposition of selected credit card 
assets to Mellon Bank Corporation in 1991, and having acted as co-manager in 
its common stock offering in 1991, and we can be expected to continue to 
provide investment banking and financial advisory services to Meridian. If 
the transactions contemplated by the Meridian/CoreStates Agreement are 
completed, each share of Meridian Common Stock will be converted into the 
right to receive 1.225 shares of common stock, par value $1.00 per share, of 
CoreStates ("CoreStates Common Stock"), subject to possible increase under 
certain circumstances. Goldman Sachs is a full service securities firm and in 
the course of its trading activities it may from time to time effect 
transactions and hold positions in the securities of the Company, Meridian 
and CoreStates. 
    

In connection with this opinion, we have reviewed, among other things, the 
Agreement; the Meridian/CoreStates Agreement; the Proxy Statement/Prospectus, 
dated September 25, 1995, of the Company and Meridian and the Supplement 
thereto, dated the date of this opinion; Annual Reports to Stockholders and 
Annual Reports on Form 10-K of the Company, Meridian and CoreStates for the 
five years ended December 31, 1994; certain interim reports to stockholders 
and Quarterly Reports on Form 10-Q of the Company, Meridian and CoreStates; 
certain other communications from the Company, Meridian and CoreStates to 
their respective stockholders; and certain internal financial analyses and 
forecasts for the Company, Meridian and CoreStates prepared by their 
respective managements. We also have held discussions with members of the 
senior management of the Company, Meridian and CoreStates regarding the past 
and current business operations, regulatory relationships, financial 
condition and future prospects of their respective companies individually and 
as combined. In addition, we have reviewed the reported price and trading 
activity for the Shares, Meridian Common Stock and CoreStates Common Stock, 
compared certain financial and stock market information for the Company, 
Meridian and CoreStates with similar information for certain other companies 
the securities of which are publicly traded, reviewed the financial terms of 
certain recent business combinations in the banking industry and performed 
such other studies and analyses as we considered appropriate. 

<PAGE>
   
We have relied without independent verification upon the accuracy and 
completeness of all of the financial and other information reviewed by us for 
purposes of this opinion. In that regard, we have assumed, with your consent, 
that the financial forecasts, including, without limitation, cost savings and 
operating synergies projected by Meridian to result from the merger 
contemplated by the Agreement and from the Meridian/CoreStates Merger, have 
been reasonably prepared on a basis reflecting the best currently available 
judgments and estimates of the Company, Meridian and CoreStates and that such 
forecasts will be realized in the amounts and at the times contemplated 
thereby. We are not experts in the evaluation of loan portfolios for purposes 
of assessing the adequacy of the allowances for losses with respect thereto 
and have assumed, with your consent, that such allowances for each of the 
Company, Meridian and CoreStates are adequate to cover all such losses. In 
addition, we have not reviewed individual credit files nor have we made an 
independent evaluation or appraisal of the assets and liabilities of the 
Company, Meridian or CoreStates or any of their respective subsidiaries and 
we have not been furnished with any such evaluation or appraisal. We have 
assumed with your consent that each of the merger contemplated by the 
Agreement and the Meridian/CoreStates Merger will be accounted for as a 
pooling of interests under generally accepted accounting principles. 
    

Based upon and subject to the foregoing and based upon such other matters as 
we consider relevant, it is our opinion that as of the date hereof the 
Exchange Ratio pursuant to the Agreement is fair to the holders of Shares. 




Very truly yours, 



GOLDMAN, SACHS & CO.

                                   PART II 
                    INFORMATION NOT REQUIRED IN PROSPECTUS 

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS. 

   Pennsylvania law provides that a Pennsylvania corporation may indemnify 
directors, officers, employees and agents of the corporation against 
liabilities they may incur in such capacities for any action taken or any 
failure to act, whether or not the corporation would have the power to 
indemnify the person under any provision of law, unless such action or 
failure to act is determined by a court to have constituted recklessness or 
willful misconduct. Pennsylvania law also permits the adoption of a bylaw 
amendment, approved by shareholders, providing for the elimination of a 
director's liability for monetary damages for any action taken or any failure 
to take any action unless (1) the director has breached or failed to perform 
the duties of his office and (2) the breach or failure to perform constitutes 
self-dealing, willful misconduct or recklessness. 

   The bylaws of Meridian provide for (1) indemnification of directors, 
officers, employees and agents of the registrant and its subsidiaries and (2) 
the elimination of a director's liability for monetary damages, to the 
fullest extent permitted by Pennsylvania law. 

   Directors and officers are also insured against certain liabilities for 
their actions, as such, by an insurance policy obtained by Meridian.

ITEM 22. UNDERTAKINGS. 

   (a) The undersigned registrant hereby undertakes: 

     (1) To file, during any period in which offers or sales are being made, 
a post-effective amendment to this registration statement: 

       (i) To include any prospectus required by section 10(a)(3) of the 
   Securities Act of 1933; 

       (ii) To reflect in the prospectus any fact or events arising after the 
   effective date of the registration statement (or the most recent 
   post-effective amendment thereof) which, individually or in the aggregate, 
   represent a fundamental change in the information set forth in the 
   registration statement; 

       (iii) To include any material information with respect to the plan of 
   distribution not previously disclosed in the registration statement or any 
   material change to such information in the registration statement. 

      (2) That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be deemed to 
be a new registration statement relating to the securities offered therein, 
and the offering of such securities at that time shall be deemed to be the 
initial bona fide offering thereof. 

      (3) To remove from registration by means of a post-effective amendment 
any of the securities being registered which remain unsold at the termination 
of the offering. 

   (b) The undersigned registrant hereby undertakes to deliver or cause to be 
delivered with the prospectus, to each person to whom the prospectus is sent 
or given, the latest annual report to security holders that is incorporated 
by reference in the prospectus and furnished pursuant to and meeting the 
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 
1934; and, where interim financial information required to be presented by 
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, 
or cause to be delivered to each person to whom the prospectus is sent or 
given, the latest quarterly report that is specifically incorporated by 
reference in the prospectus to provide such interim financial information. 

   (c) (1) The undersigned registrant hereby undertakes as follows: that 
   prior to any public reoffering of the securities registered hereunder 
   through use of a prospectus which is a part of this registration 
   statement, by any person or party who is deemed to be an underwriter 
   within the meaning of Rule 145(c), the issuer undertakes that such 
   reoffering prospectus will contain the information called for by the 
   applicable registration form with respect to reofferings by persons who 
   may be deemed underwriters, in addition to the information called for by 
   the other Items of the applicable form. 

       (2) The registrant undertakes that every prospectus (i) that is filed 
   pursuant to paragraph (1) immediately preceding, or (ii) that purports to 
   meet the requirements of section 10(a)(3) of the Act and is used in 
   connection with an offering of securities subject to Rule 415, will be 
   filed as a part of an amendment to the registration statement and will not 
   be used until such amendment is effective, and that, for purposes of 
   determining any liability under the Securities Act of 1933, each such 
   post-effective amendment shall be deemed to be a new registration 
   statement relating to the securities offered therein, and the offering of 
   such securities at that time shall be deemed to be the initial bona fide 
   offering thereof. 

   (d) Insofar as indemnification for liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers and 
controlling persons of the registrant pursuant to the bylaws of the 
registrant, or otherwise, the registrant has been advised that in the opinion 
of the Securities and Exchange Commission such indemnification is against 
public policy as expressed in the Act and is, therefore, unenforceable. In 
the event that a claim for indemnification against such liabilities (other 
than the payment by the registrant of expenses incurred or paid by a 
director, officer or controlling person of the registrant in the successful 
defense of any action, suit or proceeding) is asserted by such director, 
officer or controlling person in connection with the securities being 
registered, the registrant will, unless in the opinion of its counsel the 
matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnification by it is 
against public policy as expressed in the Act and will be governed by the 
final adjudication of such issue. 

   (e) The undersigned registrant hereby undertakes to respond to requests 
for information that is incorporated by reference into the prospectus 
pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of 

                                      II-3

<PAGE>
receipt of such request, and to send the incorporated documents by first 
class mail or other equally prompt means. This includes information contained 
in documents filed subsequent to the effective date of the registration 
statement through the date of responding to the request. 

   (f) The undersigned registrant hereby undertakes to supply by means of a 
post-effective amendment all information concerning a transaction, and the 
company being acquired involved therein, that was not the subject of and 
included in the registration statement when it became effective. 

                                      II-4
