                                PROXY STATEMENT
     for the Annual Meeting of Shareholders to be held on October 30, 1997
 
    This proxy statement is provided in connection with the 1997 Annual Meeting
of Shareholders of Baltimore Gas and Electric Company (the Company or BGE). If
the proposed merger between BGE and PEPCO is completed prior to the scheduled
annual meeting date of October 30, 1997, the meeting will be canceled. BGE's
principal executive offices are located at 39 W. Lexington Street, Baltimore,
Maryland 21201. Proxies are solicited so that all common shares may be voted.
Shares cannot be voted unless the owner of record is present or represented by
proxy at the Annual Meeting. By completing and returning the accompanying proxy
card, the shareholder authorizes Messrs. Jerome W. Geckle, George V. McGowan, or
Christian H. Poindexter, as designated on the face of the proxy, to vote all
shares for the shareholder. All returned proxies which are properly executed
will be voted as the shareholder directs. If no direction is given, the executed
proxies will be voted FOR each of the directors and FOR the ratification of
BGE's appointment of Coopers & Lybrand L.L.P. as independent auditors. A proxy
may be revoked by a shareholder at any time before it is voted at the Annual
Meeting by giving notice of revocation to the Company in writing, by execution
of a later dated proxy, or by attending and voting at the Annual Meeting.
 
    The accompanying proxy is solicited on behalf of the Board of Directors by
the Company, through its directors, officers, and other employees. In addition,
the Company has retained Georgeson & Co. Inc., a proxy solicitation firm, to
assist in the solicitation, and it is anticipated that the fee for these
services will not exceed $13,500 plus out-of-pocket expenses. Solicitations will
be made primarily through the use of the mail, but they may also be made in
person, by telephone, or by FAX. The Company bears the cost of soliciting
proxies. This proxy statement and the accompanying proxy card are being sent or
given to shareholders beginning on or about September 10, 1997. The 1996 Annual
Report to shareholders was mailed in March, 1997.
 
    Common shareholders of record at the close of business on September 2, 1997,
will be entitled to vote at the Annual Meeting. Each share will be entitled to
one vote. On July 1, 1997, the Company had outstanding 147,667,114 shares of
common stock, without par value. The presence in person or by proxy of the
holders entitled to cast 73,833,558 votes (a majority of all the votes entitled
to be cast at the meeting) will constitute a quorum. Broker non-votes,
abstentions and withhold-authority votes all count for the purpose of
determining a quorum. Each item on the agenda must receive the affirmative vote
of a majority of the shares voted at the meeting in order to pass. Broker
non-votes, abstentions and withhold-authority votes do not count as shares voted
at the meeting.

                                       4

    The Audit Committee of the Board of Directors, comprised of outside
directors, recommends an auditing firm to be engaged, discusses the scope of the
examination with that firm, and reviews the annual financial statements with the
auditing firm and with Management of the Company. Additionally, the Committee
meets with the Manager of the Auditing Department of the Company to ensure that
an adequate program of internal auditing is being carried out, and invites
comments and recommendations from the auditing firm concerning the system of
internal controls and accounting procedures. The Audit Committee reports on its
activities periodically to the Board of Directors.
 
    The Committee on Nuclear Power monitors the performance and safety of the
Company's Calvert Cliffs Nuclear Power Plant. The Committee meets periodically,
usually on-site at the Calvert Cliffs plant, to confer with Management, senior
plant management, and other nuclear oversight personnel. Following each meeting,
the Committee reports the results of its observations and findings to the Board
of Directors and makes such recommendations as it deems appropriate.
 
    The Committee on Management's duties include recommending to the Board of
Directors nominees for election as directors and officers and making
recommendations concerning remuneration arrangements for directors and officers
of the Company. This Committee, which is comprised of outside directors,
considers nominees recommended by shareholders; such recommendations should be
submitted in writing to the attention of the Corporate Secretary, Baltimore Gas
and Electric Company, 39 W. Lexington Street, Baltimore, Maryland 21201.
 
    The Committee on Workplace Diversity provides an ongoing Board of Directors'
perspective of management's progress in achieving employee diversity goals. The
Committee provides input to management in setting goals and developing
strategies to increase goal attainment, provides oversight on implementation of
strategies, and evaluates results. The Committee on Workplace Diversity reports
on its activities periodically to the Board of Directors.
 
    The Long Range Strategy Committee provides an oversight role in the
development of the Company's long range strategic goals. The Committee meets
periodically to review the continued appropriateness of these goals and to
approve presentations to the Board regarding the implementation of significant
strategic initiatives. This Committee also reviews major regulatory,
environmental and public policy issues as well as technology advances which may
impact Company operations. The Long Range Strategy Committee reports on its
activities periodically to the Board of Directors.
 
    The Board of Directors met nine times during 1996 for regularly scheduled
meetings. The Committee on Management met five times, the Audit Committee met
four times, the Committee on Nuclear Power met three times, and the Committee on
Workplace Diversity and the Executive Committee each met two times. Each of the
nominees attended 75% or more of the total number of meetings of the Board and
of any committees on which the nominee served.
 
    Each director, who is not an officer or employee of the Company or its
subsidiaries, receives a fee of $1,250 for each regular, committee, or special
meeting of the Board attended and a retainer
 
                                       5

fee of $26,000 per year. Each committee chairman receives an additional annual
retainer fee of $3,500 per year. Both Board and Committee Chair retainers are
paid 1/2 in deferred stock units. The units' value fluctuates in relation to
market price, dividends paid, and other capital changes like stock splits.
Directors may elect to receive the other 1/2 of their retainers in cash or in
deferred stock units. Each director may be reimbursed for reasonable travel
expenses incidental to attendance at meetings. Each director who is not an
officer or employee may elect to defer receipt of any portion of the fees
earned. The Company also provides an automobile to Mr. McGowan, a director who
retired on December 31, 1992 as Chairman of the Board and Chief Executive
Officer of the Company and who continues to participate in civic and community
activities on behalf of the Company. The approximate yearly cost to the Company
is $7,908.
 
    The Company terminated its directors retirement plan effective August 1,
1997. The decision to terminate the plan was based on surveys of other
companies' practices and shareholder feedback.
 
CERTAIN RELATIONSHIPS AND TRANSACTIONS
 
    The Company and certain of its subsidiaries paid legal fees during 1996 to
the law firm of Piper & Marbury L.L.P. of which Mr. George L. Russell, Jr., a
Company director, is a partner. It is expected that the Company and subsidiaries
will continue to do business with this firm in 1997.

(1) At December 31, 1996, Mr. Poindexter held 26,635 shares of performance-based
    Restricted Stock with a value of $712,486, Mr. Crooke held 19,085 shares of
    performance-based Restricted Stock with a value of $510,524, Mr. Creel held
    17,224 shares of performance-based Restricted Stock with a value of

    Stock with a value of $438,727, and Mr. Denton held 12,952 shares of
    performance-based Restricted Stock with a value of $346,466. Dividends on
    performance-based Restricted Stock Awards are accumulated during the

                 NOTES TO SUMMARY COMPENSATION TABLE-CONTINUED
(2) The amounts in the LTIP PAYOUT column were paid for performance during the
    1994-1996 period.
 
(3) The amounts in the ALL OTHER COMPENSATION column include the Company match
    under the Company's savings plans; the interest on the cumulative corporate
    funds used to pay annual premiums on policies providing split-dollar life
    insurance benefits (calculated at the Internal Revenue Service's blended
    rate); and a contribution to a trust securing the executives' supplemental
    pension benefits. These amounts also include a one-time contribution by BGE
    to fund a trust that was established in 1996 to secure executives'
    nonqualified deferred compensation plan benefits. The nonqualified deferred
    compensation plan was put in place in 1988 to permit executives to defer
    compensation and establish phantom investment accounts equivalent to the
    compensation being deferred. The amount of the funding is equal to the
    interest, dividends and capital appreciation recorded in those accounts
    since 1988. A breakdown of the 1996 amounts in the ALL OTHER COMPENSATION
    column is shown on the chart below. Notes (a), (b), and (c) under the chart
    include important background data. Both the chart and the background data
    are needed to understand the numbers in the ALL OTHER COMPENSATION column.

(a) The Company match and split-dollar amounts shown in column (a) above were
    the only items included in the ALL OTHER COMPENSATION column for 1995 and
    1994.
 
(b) An initial contribution to the trust securing supplemental pension benefits

    or 1994.
 
(c) A ONE-TIME contribution was made during 1996 to the trust securing deferred
    compensation plan benefits equal to the interest, dividends and capital
    appreciation on plan accounts SINCE 1988. Therefore, there were no trust

LONG-TERM INCENTIVE PLAN TABLE
 
    The Committee on Management, effective February 12, 1997, made grants of
performance-based restricted shares under the Long-Term Incentive Plan.
 
    For each named executive, the grants are subject to both performance and
time (3 years) contingencies. For all but Mr. Ambler, performance will be
measured by comparing BGE's total shareholder return to the Dow Jones Electric
Utilities Index. Both are shown in the performance graph on page 14. A threshold
award will be earned if the BGE three-year cumulative total shareholder return
percentile rank is at the 50th percentile, progressing to a maximum award for a
return at or above the 75th percentile. At the proposed merger effective date,
the shares of restricted BGE stock outstanding will be converted to shares of
restricted Constellation Energy Corporation common stock, using the proposed
merger conversion ratio: one share of Constellation Energy Corporation common
stock for each share of BGE common stock. After the proposed merger effective
date, the total shareholder return measure will be based upon the return taking
into account the growth in common stock value of Constellation Energy
Corporation and dividends. For Mr. Ambler, the performance measure relates to
improvement in Constellation Holdings' net income over the performance period.
 
    Pursuant to the grants, restricted shares were issued equivalent to the
number of shares that will be earned if "target" performance (62.5th percentile)
is achieved. These restricted shares will be forfeited in whole or part, if
performance is below target. Dividends on the restricted shares will be
accumulated during the performance period and reinvested in BGE shares. Actual
dividends awarded at the end of the performance period will be based upon
performance and paid in stock (except that the recipients may elect to have a
portion of the shares withheld to satisfy tax withholding requirements).
Additional shares, up to the maximum number noted below, will be awarded if
performance is above target at the end of the 1997-1999 performance period.
Dividend equivalents from the date of the grant will be paid for any additional
shares that are awarded.

(A) The target number of shares have been issued. If fewer shares are actually
    earned during the performance period, all or some shares will be forfeited;
    if additional shares are actually earned during the performance period,
    additional shares, up to the maximum listed, will be issued.

PENSION BENEFITS
 
    The following table shows annual pension benefits payable upon normal
retirement to executives, including the five individuals named in the Summary
Compensation Table. Normal retirement occurs at age 65 for Messrs. Poindexter,
Crooke, and Ambler, and at age 62 for all other executives. Pension benefits are
computed at 60% of total final average salary plus bonus for Messrs. Poindexter,
Crooke, and Ambler, without regard to years of service. Pension benefits are
computed at 55% of total final average salary plus bonus for Mr. Creel, who has
attained the maximum credited years of service. Pension benefits are computed at
50% of total final average salary plus bonus for Mr. Denton and, when he attains
30 years service in 2000, will be computed at 55%.

    Salary and bonus are calculated in the same manner shown in the Summary
Compensation Table. There is no offset of pension benefits for social security
or other amounts.
 
    During 1994, the Company implemented a program to secure the supplemental
pension benefits for each of the executive officers, including those listed in
the Summary Compensation Table. During 1996, the Company implemented a program
to secure deferred compensation of executive officers including those listed in
the Summary Compensation Table. These programs do not increase the amount of
supplemental pension benefits or deferred compensation. In the past, both
supplemental pension benefits and deferred compensation were unfunded--that
means no money was set aside on behalf of the executive as he earned the
benefit, and the benefits were paid from the Company's
 
                                       12

general funds when the executive retired. To provide security, accrued
supplemental pension benefits and deferred compensation are now being funded
through a trust at the time they are earned. An executive officer's accrued
benefits in the supplemental pension trust become vested when any of these
events occur: retirement eligibility; termination, demotion or loss of benefit
eligibility without cause; a change of control of the Company followed within
two years by the executive's demotion, termination or loss of benefit
eligibility; or reduction of previously accrued benefits. As a result of
becoming vested, the executive would be entitled to a payout of the vested
amount from the supplemental pension trust upon the later of age 55 or
employment termination. An executive's benefits under the deferred compensation
plan always are fully vested and are payable at employment termination. Payments
to these trusts are included in the Summary Compensation Table in the ALL OTHER
COMPENSATION column.
 
AGREEMENTS RELATING TO THE PROPOSED MERGER
 
    In connection with the proposed merger, Messrs. Poindexter and Crooke each
signed an employment agreement dated as of September 22, 1995 with Constellation
Energy Corporation. Mr. Poindexter's agreement provides that he will serve as
Chief Executive Officer from the time the proposed merger is completed and that
he will become Chairman one year after the proposed merger is completed. Mr.
Crooke's agreement provides that he will serve as Vice Chairman of Constellation
Energy Corporation and also as Chairman of all the non-utility subsidiaries.
These agreements remain in effect for five years after the proposed merger is
completed.
 
    In December 1995, BGE entered into severance agreements with 15 key
employees. The agreements become binding on Constellation Energy Corporation at
the time the proposed merger is completed and remain in effect for two years
thereafter. The severance agreements provide for the payment of severance
benefits to the executive under certain circumstances including, but not limited
to, the following (i) upon termination of employment (other than for cause,
death, disability or the executive's voluntary termination of employment without
"good reason") within the two year period following the time the proposed merger
is completed or (ii) termination of the executive's employment without cause or
the executive's voluntary termination following the occurrence of certain events
that constitute "good reason" prior to the time the proposed merger is
completed.
 
    Four of the 15 key employees who have severance agreements with BGE are
retiring when the proposed merger closes and are entitled to severance benefits.
All other key employees who have severance agreements have been offered, and
accepted, executive positions with Constellation Energy Corporation and will not
be eligible for severance benefits when the proposed merger closes. If the four
retiring employees had been terminated as of December 31, 1996, under
circumstances giving rise to an entitlement to benefits thereunder, the
aggregate value of such benefits would have been approximately: $750,000 for Mr.
Creel, and an aggregate of $2 million for the other executives, none of whom is
named in the Summary Compensation Table.

REPORT OF COMMITTEE ON MANAGEMENT
REGARDING EXECUTIVE COMPENSATION
 
The Committee on Management, made up completely of outside Directors, is
responsible for executive compensation policies. In addition to establishing
policies, the Committee approves all compensation plans and recommends to the
Board of Directors specific salary amounts and other compensation awards for
individual executives.
 
                                       14

    The Committee designs compensation policies to encourage executives to
manage BGE in the best long-term interests of shareholders and to allow BGE to
attract and retain executives best suited to lead BGE in a changing industry.
 
    The Committee determined that the relevant labor market for executives is
the utility industry. Utilities used for comparison in 1996 were electric
utilities and combination electric/gas utilities that have annual revenues in
the $2-5 billion range, adjusted by using regression analysis to account for
BGE's size. These utilities are thought to best represent the portion of the
executive labor market in which BGE competes. All of these utilities are
included in the Dow Jones Electric Utilities Index shown on the Performance
Graph.
 
    The Committee's philosophy is that base salary should approximate the middle
of that labor market for average performance, and that short-term and long-term
incentive awards for superior performance should bring total compensation to
approximately the 75th percentile of the labor market. Total compensation is
made up of three components: base salary, short-term incentive awards, and
long-term incentive awards. As described below, corporate performance is one of
the criteria used by the Committee in determining base salary, and it is a key
component in determining both short-term and long-term incentive awards.
 
    The Committee has retained an outside executive compensation consultant
since 1993. He provides information and advice on a regular basis. In addition,
internal compensation analysts (certified by the American Compensation
Association) use survey data, outside consultants, and other resources to make
recommendations to the Committee.
 
    Base salary ranges did not change for the named executives in 1996 except
Mr. Creel. He was elected Executive Vice President and named acting Chief
Operating Officer during 1996 to allow Mr. Crooke time for leading the proposed
merger transition team. Both his salary range and his base salary were increased
to reflect these new responsibilities.
 
    Salary increases during 1996 for Mr. Poindexter and the other named
executives were based upon 1995 corporate performance (consolidated corporate
earnings from ongoing operations increased 4.5%, or $.09 per share, in 1995
compared to 1994, and utility earnings from ongoing operations increased 1.6%,
or $0.03 per share, in 1995 compared to 1994), and the corporate response to
changes in the industry and the regulatory environment. Mr. Poindexter's base
salary increase of 5.6% moved him to the middle third of his salary range.
 
    Bonus payments to Mr. Poindexter and other executives represent the
short-term incentive component of executive compensation. The Committee sets
short-term incentive amounts, as well as the mix among base salary, short-term
incentive compensation and long-term incentive compensation, to bring total
compensation in line with survey data for the relevant labor market. For 1996
short-term incentive awards, the Committee determined that the appropriate
measure for earnings was earnings from ongoing operations. This had the effect
of eliminating the $.42 per share reduction
 
                                       15

related to the write-off of $83 million for deferred fuel costs from the
extended 1989-1991 outage at BGE's Calvert Cliff's Nuclear Power Plant. In
making this decision, the Committee gave weight to the following facts: (a) the
$118 million settlement amount (the $83 million written off in 1996 plus the $35
million reserve taken in 1990) is considerably lower than initial demands of
People's Counsel ($458 million) and PSC Staff ($200 million), (b) the total
maintenance performed during the extended outage resulted in the plant being in
excellent operating condition, as evidenced by its good operating history since
the end of the extended outage, (c) leadership provided by the executives to the
team that handled the litigation and negotiated the settlement. Mr.
Poindexter's, Mr. Crooke's, and Mr. Creel's short-term bonuses were based on two
factors of equal importance: corporate earnings (an increase of 8.6%, or $.18
per share, in 1996 compared to 1995); and corporate business plan performance in
the following areas: customer satisfaction, innovation, and internal business
perspectives. Mr. Denton's short-term incentive bonus was based upon two factors
of equal importance: higher consolidated corporate earnings as described above,
and achievement of operational targets contained in the Fossil Energy and
Nuclear Energy divisions' business plans. Mr. Ambler's bonus was based upon net
income from Constellation Holdings ($42.3 million in 1996, an increase of 56.1%,
compared to $27.1 million in 1995) weighted at 50%; higher consolidated
corporate earnings as described above, weighted at 20%; and operational targets
contained in Constellation Holdings' business plan weighted at 30%.
 
    Early this year the named executives received cash long-term bonuses for the
1994-1996 performance period. These awards were earned under a cash Long-Term
Performance Program for executive officers, including Mr. Poindexter, adopted in
1993. The Program was designed to tie the awards directly to total shareholder
return. These awards were the only awards made under the Program. Program
objectives for Messrs. Poindexter, Crooke, Creel, and Denton are based upon BGE
total shareholder return during the period 1994-1996 compared to total
shareholder return for the other companies included in the Dow Jones Electric
Utilities Index (one of the indices used in the Performance Graph). Performance
(61st percentile) exceeded the target of (60th percentile) and produced awards
that were slightly above target. For Mr. Ambler, the performance objectives
measured improvement in Constellation Holdings' net income over the same three
year period. He received a maximum award based upon an improvement in net income
of 255%. Awards to the named executives are disclosed in the column of the
Summary Compensation Table titled LONG-TERM COMPENSATION-LTIP PAYOUT.
 
    The current Long-Term Incentive Plan was approved by the shareholders at the
1995 Annual Meeting of Shareholders and will be in effect until 2005. The
Committee specifically included numerous features in the Long-Term Incentive
Plan to allow various types of awards keyed to corporate performance, including
performance shares and restricted stock subject to performance-based
contingencies. Awards in 1995 and 1996 of performance-based restricted stock
were granted under the Plan to the named executives and are included in footnote
1 to the Summary Compensation Table on page 9. Awards of performance-based
restricted stock granted in 1997 to the named
 
                                       16

executives are shown on the Long-Term Incentive Plan table on page 11. The
awards are subject to forfeiture if corporate performance criteria are not
satisfied or if the executive's employment terminates during the applicable
three year performance periods. The corporate performance criteria for all named
executives except Mr. Ambler for each period is measured by total shareholder
return over the performance period compared to total shareholder return for the
other companies included in the Dow Jones Electric Utilities Index (one of the
indices used in the Performance Graph) and are as follows: a threshold award at
the 50th percentile, progressing to a maximum payout if percentile rank for
total shareholder return exceeds the 75th percentile. For Mr. Ambler, the
performance objectives for all the awards measure improvement in Constellation
Holdings' net income over the same three year period.
 
    In making long-term incentive awards the Committee considers the desired
amount of total compensation and the appropriate mix among base salary,
short-term incentive compensation, and long-term incentive compensation. The
Committee sets long-term incentive target amounts to bring total compensation in
line with survey data for the relevant labor market. Measures for performance-
based long-term incentive awards are based upon total shareholder return.
 
    The Committee evaluated the total director compensation package and,
together with their counterparts from PEPCO, will recommend the compensation
package that makes the most sense for the new company. Matters under
consideration include whether compensation should be paid in stock, cash or a
mix, and what structure (a retainer, meeting fees, and other benefits, if any)
is optimal. The Board, on the Committee's recommendation, terminated the
directors retirement plan August 1, 1997. The decision to terminate the plan was
based on surveys of other companies' practices and shareholder feedback.
 
    Section 162(m) of the Internal Revenue Code limits tax deductions for
executive compensation to $1 million. There are several exemptions to Section
162(m), including one for qualified performance-based compensation. To be
qualified, performance-based compensation must meet various requirements,
including shareholder approval. The Committee has considered annually whether it
should adopt a policy regarding 162(m) and concluded it was not appropriate to
do so. One reason for the conclusion is that, assuming the current compensation
policies and philosophy remain in place, Section 162(m) will not be applicable
in the near term for any executive's compensation. However, the Committee also
notes that while generally it wishes to maximize the deductibility of
compensation, the Committee believes the 162(m) requirements are not fully
consistent with sound executive compensation policy and incentives to improve
shareholder value. Therefore, the Committee may in the future approve incentive
payments that do not qualify for deduction if the recipient's compensation
exceeds the $1 million limit.

ITEM 2. RATIFICATION OF BGE'S APPOINTMENT OF AUDITORS
 
    Coopers & Lybrand L.L.P., Certified Public Accountants, have been the
Company's independent auditors since 1941. UNLESS THE COMMON STOCK SHAREHOLDER
OTHERWISE SPECIFIES IN THE PROXY, THE VOTES REPRESENTED BY THE COMMON STOCK
PROXIES WILL BE CAST FOR THE RATIFICATION OF BGE'S APPOINTMENT OF COOPERS &
LYBRAND L.L.P. AS INDEPENDENT AUDITORS FOR THE COMPANY FOR THE YEAR 1997. A
member of Coopers & Lybrand L.L.P. will be present at the Annual Meeting and
will be given an opportunity to make a statement and answer appropriate
questions.
 
    The consolidated financial statements for the previous fiscal year were
examined by Coopers & Lybrand L.L.P. In connection with the auditor function,
Coopers & Lybrand L.L.P. also reviewed the Company's annual report, its filings
with the Securities and Exchange Commission and Federal Energy Regulatory
Commission, and examined the financial statements of various Company benefit
plans.
 
    The Audit Committee of the Board of Directors has approved each professional
service provided by Coopers & Lybrand L.L.P. during the previous fiscal year,
each of which was furnished at customary rates and terms, and has determined
that the performance of each service does not impair the independence of Coopers
& Lybrand L.L.P. as auditors for the Company.
 
OTHER MATTERS
 
    The Board of Directors knows of no matters to be presented for action at the
Annual Meeting other than the two items mentioned above. However, if any other
matters come before the Annual Meeting, if any of the persons named to serve as
directors or as auditors should be unable to serve or for good cause will not
serve, if any proposal omitted from the proxy statement and proxy are presented
for action at the Annual Meeting, and any matters incident to the conduct of the
Annual Meeting are presented for action at the Annual Meeting, it is intended
that the persons named in the proxy will vote on such matters in accordance with
their best judgment.
 
SHAREHOLDER PROPOSALS FOR 1998
 
    Proposals by shareholders intended to be presented at the 1998 Annual
Meeting must be received no later than November 6, 1997 for inclusion in the

                Dear Shareholder:
 
                As of October 3, 1997, we had not received your proxy for
                the 1997 annual shareholders meeting to be held October
                30th.
 
                We appreciate the support of our shareholders and
                encourage you to vote your proxy, regardless of the size
                of your holdings. We have, therefore, enclosed a second
                proxy so that you can vote your shares. Whether or not
                you plan to attend the meeting, we would appreciate you
                executing the proxy and returning it promptly to assure
                that your vote will be counted at the meeting.
 
                Our initial mailing to you also included a proxy
                statement. If you would like to receive a duplicate copy
                of this document, simply contact one of our shareholder
                representatives in metropolitan Baltimore at

                Chairman of the Board
