               WARRANT TO PURCHASE 481,434 SHARES OF COMMON STOCK

                                       OF

                            BLUESTONE SOFTWARE, INC.

         This is to certify that, FOR VALUE RECEIVED, BT ALEX. BROWN
INCORPORATED or its registered assigns pursuant to Section (d) hereof
("Holder"), is entitled to purchase, subject to the provisions of this
Warrant, from Bluestone Software, Inc. a Delaware corporation (the
"Company"), 481,434 fully paid, validly issued and nonassessable shares of
Common Stock, par value $0.001 per share, of the Company ("Common Stock"), at
the exercise price of $2.72 per share. The number of shares of Common Stock
to be received upon the exercise of this Warrant and the price to be paid for
each share of Common Stock may be adjusted from time to time as hereinafter
set forth. The shares of Common Stock deliverable upon such exercise, and as
adjusted from time to time, are hereinafter sometimes referred to as "Warrant
Shares," and the exercise price of a share of Common Stock as adjusted from
time to time is hereinafter sometimes referred to as the "Exercise Price."

         (a) EXERCISE OF WARRANT. The Warrant may be exercised at any time, or
from time to time, by presentation and surrender hereof to the Company at its
principal office, or at the office of its stock transfer agent, if any, with the
Purchase Form annexed hereto duly executed (with signature guaranteed if
required by the Company or its stock transfer agent) and accompanied by payment
of the Exercise Price for the number of Warrant Shares specified in such form
and any applicable taxes. The purchase price for any Warrant Shares purchased
pursuant to the exercise of this Warrant shall be paid in full upon such
exercise in cash or by certified or bank check or pursuant to a cashless
exercise procedure whereby the Warrant Shares issued upon exercise of this
Warrant will be sold by the Holder or Holder's agent with Holder receiving the
difference between the Exercise Price and the sale price, in cash, and the
Company receiving the Exercise Price for the Warrant Shares, in cash, or any
combination of the foregoing methods of paying the Exercise Price. As soon as
practicable after each such exercise of the Warrants, but not later than seven
(7) business days from the date of such exercise, the Company shall issue and
deliver to the Holder a certificate or certificates for the Warrant Shares
issuable upon such exercise, registered in the name of the Holder or the
Holder's designee, except in the case of a cashless exercise. If the Warrant
should be exercised in part only, the Company shall, upon surrender of the
Warrant for cancellation, execute and deliver a new Warrant evidencing the
rights of the Holder thereof to purchase the balance of the Warrant Shares
purchasable thereunder. In the event of a cash exercise, upon receipt by the

                                        1





Company of the Warrant at its office, or by the stock transfer agent of the
Company at its office, in proper form for exercise, together with the exercise
price thereof and taxes as aforesaid in cash or certified or bank check and the
investment letter described below, the Holder shall be deemed to be the holder
of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder. In order to assure the availability
of an exemption from registration under the federal or applicable state
securities laws, the Company may condition the exercise of the Warrant upon the
Holder delivering to the Company an investment letter in the form as customarily
used by the Company from time to time in connection with the exercise of
non-registered options and warrants which are issued by the Company. It is
further understood that certificates for the Warrant Shares, if any, to be
issued upon exercise of the Warrant may contain a restrictive legend in
accordance with Section (j) hereof.

         (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants. If the Common Stock is or becomes listed on any national
securities exchange or the NASDAQ National Market System, the Company shall also
list such shares on such exchange subject to notice of issuance or maintain the
listing of its Common Stock on the NASDAQ system, as the case may be.

         (c) FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant. With respect
to any fraction of a share called for upon any exercise hereof, the Company
shall pay to the Holder an amount in cash equal to such fraction multiplied by
the current market value of a share, determined as follows:

                           (1) If the Common Stock is listed on a national
                  securities exchange or admitted to unlisted trading privileges
                  on such exchange or listed for trading on the NASDAQ National
                  Market System, the current market value shall be the last
                  reported sale price of the Common Stock on such exchange or
                  system on the last business day prior to the date of exercise
                  of this Warrant or if no such sale is made on such day, the
                  average closing bid and asked prices for such day on such
                  exchange or system;

                           (2) If the Common Stock is not so listed or admitted
                  to unlisted trading privileges, the current market value shall
                  be the mean of the last reported bid and asked prices reported
                  by the National Quotation Bureau, Inc., on the last business
                  day prior to the date of the exercise of this Warrant; or

                           (3) If the Common Stock is not so listed or admitted
                  to unlisted trading privileges and bid and asked prices are
                  not so reported, the current market value shall be an amount,
                  not less than the book value thereof as at the end of the most
                  recent fiscal year of the Company ending prior to the date of
                  the exercise of the Warrant,

                                        2





                  determined in such reasonable manner as may be prescribed by
                  the Board of Directors of the Company.

         (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. The Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other Warrants of different denominations entitling the
Holder thereof to purchase in the aggregate the same number of shares of Common
Stock purchasable hereunder. Subject to Section (j) hereof, the Holder may
transfer or assign the Warrant, in whole or in part and from time to time. Upon
surrender of this Warrant to the Company at its principal office or at the
office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed (with signature guaranteed, if required by the Company or
its stock transfer agent) and funds sufficient to pay any transfer tax, the
Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee or assignees named in such instrument of assignment and this
Warrant shall promptly be canceled. This Warrant may be divided by or combined
with other Warrants which carry the same rights upon presentation hereof at the
principal office of the Company or at the office of its stock transfer agent, if
any, together with a written notice specifying the names and denominations in
which new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants into which this Warrant my be
divided or exchanged. Upon receipt by the Company of evidence satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant, and in the case
of loss, theft or destruction, of reasonable satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor, date and amount. Any such new
Warrant executed and delivered shall constitute a binding contractual obligation
on the part of the Company.

         (e) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

         (f) ANTI-DILUTION PROVISIONS. So long as this Warrant shall be
outstanding, the Exercise Price in effect at any time and the number and kind of
securities purchasable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

                           (1)      SPECIAL DEFINITIONS.  For purposes of this

                                    such Convertible Securities;

                                            (B) if such Options or Convertible
                                    Securities by their terms provide, with the
                                    passage of time or otherwise, for any
                                    increase or decrease in the consideration
                                    payable to the Company, or decrease or
                                    increase in the number of shares of Common
                                    Stock issuable, upon the exercise,

                                    subsequent adjustments based thereon, shall,
                                    upon any such increase or decrease becoming

                                    (provided, however, that no such adjustment
                                    of the Exercise Price shall affect Common
                                    Stock previously issued upon the exercise of
                                    this Warrant);

                                    record date with respect thereto), and any
                                    subsequent adjustments based thereon, shall,
                                    upon such expiration, be recomputed as if:

                                                     (1) in the case of
                                    Convertible Securities or Options for Common

                                    Stock, if any, actually issued upon the
                                    exercise of such Options or the conversion
                                    or exchange of such Convertible Securities
                                    and the consideration received therefor was
                                    the consideration actually received by the
                                    Company for the issue of all such Options,
                                    whether or not exercised, plus the
                                    consideration actually received by the
                                    Company upon such exercise, or for the issue
                                    of all such Convertible Securities which
                                    were actually converted or exchanged, plus
                                    the additional consideration, if any,
                                    actually received by the Company upon such
                                    conversion or exchange; and

                                                     (2) in the case of Options
                                    for Convertible Securities, only the
                                    Convertible Securities, if any, actually
                                    issued upon the exercise thereof were issued
                                    at the time of such Options, and the
                                    consideration received by the Company for
                                    the Additional Shares of Common Stock deemed
                                    to have been then issued was the
                                    consideration actually received by the
                                    Company for the issue of all such Options,
                                    whether or not exercised, plus the
                                    consideration deemed to have been received
                                    by the Company (determined pursuant to
                                    Section (f)(5) herein) upon the issue of the
                                    Convertible Securities with respect to which
                                    such Options were actually exercised;

                                            (D) no readjustment pursuant to
                                    clause (B) or (C) above shall have the
                                    effect of increasing the Exercise Price to
                                    an amount which exceeds the lower of (a) the
                                    Exercise Price on the original adjustment
                                    date, or (b) the Exercise Price that would
                                    have resulted from any issuance of
                                    Additional Shares of Common Stock between
                                    the original adjustment date and such
                                    readjustment date; and


                                        6





                                            (E) in the case of any Options which
                                    expire by their terms not more than 30 days
                                    after the date of issue thereof, no
                                    adjustment of the Exercise Price shall be
                                    made until the expiration or exercise of all
                                    such Options, whereupon such adjustment
                                    shall be made in the same manner provided in
                                    clause (C) above.

                           (4) ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE OF
                  ADDITIONAL SHARES OF COMMON STOCK. In the event the Company,
                  at any time after the date herein, shall issue Additional
                  Shares of Common Stock (including Additional Shares of Common
                  Stock deemed to be issued pursuant to Section (f)(5) herein)
                  without consideration or for a consideration per share less
                  than the Exercise Price in effect on the date of and
                  immediately prior to such issue, then and in such event, the
                  Exercise Price under the Warrant shall be reduced concurrently
                  with such issue, to a price (calculated to the nearest cent)
                  determined by multiplying such Exercise Price by a fraction,
                  the numerator of which shall be the number of shares of Common
                  Stock outstanding immediately prior to such issue plus the
                  number of shares of Common Stock which the aggregate
                  consideration received by the Company for the total number of
                  Additional Shares of Common Stock so issued would purchase at
                  such Exercise Price in effect immediately prior to such
                  issuance, and the denominator of which shall be the number of
                  shares of Common Stock outstanding immediately prior to such
                  issue plus the number of such Additional Shares of Common
                  Stock so issued. For the purpose of the above calculation, the
                  number of shares of Common Stock outstanding immediately prior
                  to such issue shall be calculated as if all Warrants had been
                  exercised and all Convertible Securities had been fully
                  converted into shares of Common Stock immediately prior to
                  such issuance and any outstanding warrants, options or other
                  rights for the purchase of shares of stock or convertible
                  securities had been fully exercised immediately prior to such
                  issuance (and the resulting securities fully converted into
                  shares of Common Stock if so convertible) as of such date, but
                  not including in such calculation any additional shares of
                  Common Stock issuable with respect to this Warrant,
                  Convertible Securities, or outstanding options, warrants or
                  other rights for the purchase of shares of stock or
                  convertible securities, solely as a result of the adjustment
                  of the Exercise Price (or other conversion ratios) resulting
                  from the issuance of the Additional Shares of Common Stock
                  causing the adjustment in question.

                           (5) DETERMINATION OF CONSIDERATION. For purposes of
                  this Warrant, the consideration received by the Company for
                  the issue of any Additional Shares of Common Stock shall be
                  computed as follows:

                           (A) Cash and Property. Such consideration shall:

                                     (1) insofar as it consists of cash, be
                                     computed at the aggregate amount of cash
                                     received by the Company,

                                        7





                                     excluding amounts paid or payable for
                                     accrued interest or accrued dividends;

                                     (2) insofar as it consists of property
                                     other than cash, be computed at the fair
                                     value thereof at the time of such issue, as
                                     determined in good faith by the Board; and

                                     (3) in the event Additional Shares of
                                     Common Stock are issued together with the
                                     other shares or securities or other assets
                                     of the Company for consideration which
                                     covers both types of securities, be the
                                     proportion of such consideration so
                                     received, computed as provided in
                                     clauses (1) and (2) above, with respect to
                                     the Additional Shares of Common Stock as
                                     determined in good faith by the Board.

                                 (B) Options and Convertible Securities. The
                                 consideration per share received by the Company
                                 for Additional Shares of Common Stock deemed to
                                 have been issued pursuant to Section (f)(5)
                                 herein, relating to Options and Convertible
                                 Securities shall be determined by dividing:

                                      (1) the total amount, if any, received or
                                      receivable by the Company as consideration
                                      for the issue of such Options or
                                      Convertible Securities, plus the minimum
                                      aggregate amount of additional
                                      consideration (as set forth in the
                                      instruments relating thereto, without
                                      regard to any provision contained therein
                                      designed to protect against dilution)
                                      payable to the Company upon the exercise
                                      of such Options or the conversion or
                                      exchange of such Convertible Securities,
                                      or in the case of Options for Convertible
                                      Securities, the exercise of such Options
                                      for Convertible Securities and the
                                      conversion or exchange of such Convertible
                                      Securities, by

                                      (2) the maximum number of shares of Common
                                      Stock (as set forth in the instruments
                                      relating thereto, without regard to any
                                      provision contained therein designed to
                                      protect against the dilution) issuable
                                      upon the exercise of such Options or
                                      conversion or exchange of such Convertible
                                      Securities.

                           (6) ADJUSTMENTS TO EXERCISE PRICE FOR STOCK DIVIDENDS
                  AND FOR COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the
                  event that the Company at any time or from time to time after
                  the date herein shall declare or pay, without consideration,
                  any dividend on the Common Stock payable in Common Stock or in

                                        8





                  any right to acquire Common Stock for no consideration, or
                  shall effect a subdivision of the outstanding shares of Common
                  Stock into a greater number of shares of Common Stock (by
                  stock split, reclassification or otherwise than by payment of
                  a dividend in Common Stock or in any right to acquire Common
                  Stock), or in the event the outstanding shares of Common Stock
                  shall be combined or consolidated, by reclassification or
                  otherwise, into a lesser number of shares of Common Stock,
                  then the Exercise Price in effect immediately prior to such
                  event shall, concurrently with the effectiveness of such
                  event, be proportionately decreased or increased, as
                  appropriate. In the event that this Company shall declare or
                  pay, without consideration, any dividend on the Common Stock
                  payable in any right to acquire Common Stock for no
                  consideration, then the Company shall be deemed to have made a
                  dividend payable in Common Stock in an amount of shares equal
                  to the maximum number of shares issuable upon exercise of such
                  rights to acquire Common Stock.

                           (7) ADJUSTMENTS FOR RECLASSIFICATION AND
                  REORGANIZATION. If the Common Stock issuable upon the exercise
                  of the Warrants shall be changed into the same or a different
                  number of shares of any other class or classes of stock,
                  whether by capital reorganization, reclassification or
                  otherwise, the Exercise Price then in effect shall,
                  concurrently with the effectiveness of such reorganization or
                  reclassification, be proportionately adjusted so that the
                  Warrants shall be exercised for, in lieu of the number of
                  shares of Common Stock which the holders would otherwise have
                  been entitled to receive, a number of shares of such other
                  class or classes of stock equivalent to the number of shares
                  of Common Stock that would have been subject to receipt by the
                  holders upon the exercise of the Warrant immediately before
                  that change.

                           (8) No adjustment in the Exercise Price shall be
                  required unless such adjustment would require an increase or
                  decrease of at least $.05 in such price; provided, however,
                  that any adjustments which by reason of this subsection (f)
                  (8) are not required to be made shall be carried forward and
                  taken into account in any subsequent adjustment required to be
                  made hereunder.

                           (9) Whenever the Exercise Price is adjusted, as
                  herein provided, the Company shall promptly cause a notice
                  setting forth the adjusted Exercise Price and adjusted number
                  of Warrant Shares issuable upon exercise of each Warrant to be
                  mailed to the Holder, at its address appearing in the Warrant
                  Register, and shall cause a certified copy thereof to be
                  mailed to its transfer agent, if any.

                           (10) All calculations under this Section (f) shall be
                  made to the nearest cent or to the nearest Warrant Share, as
                  the case may be.


                                        9





                           (11) In the event that at any time, as a result of an
                  adjustment made pursuant to this Section (f) above, the Holder
                  of this Warrant thereafter shall become entitled to receive
                  any shares of the Company, other than Common Stock, thereafter
                  the number of such other shares so receivable upon exercise of
                  this Warrant shall be subject to adjustment from time to time
                  in a manner and on terms as nearly equivalent as practicable
                  to the provisions with respect to the Common Stock contained
                  in subsection (A) above.

                           (12) Irrespective of any adjustments in the Exercise
                  Price or the number or kind of Warrant Shares purchasable upon
                  exercise of this Warrant, Warrants theretofore or thereafter
                  issued may continue to express the same price and number and
                  kind of shares as are stated in the similar Warrants initially
                  issuable pursuant to this Warrant.

         (g) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
adjusted as required by the provisions of the foregoing Section, the Company
shall forthwith file in the custody of its Secretary or an Assistant Secretary
at its principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment. Each such officer's certificate shall be
made available at all reasonable times for inspection by the Holder or any
holder of a Warrant executed and/or delivered pursuant to Section (a) or Section
(d), and the Company shall, forthwith after each such adjustment, mail, by

         (h) NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (i) if the Company shall pay any dividend or make any distribution

         (i)      SECURITIES LAW COMPLIANCE

                           (1) The Holder of the Warrant, by acceptance hereof,
                  acknowledges that the Warrant and the shares of Common Stock
                  to be issued upon exercise hereof or conversion thereof are
                  being acquired solely for the Holder's own account and not as
                  a nominee for any other party, and for investment, and that
                  the Holder will not offer, sell, transfer, assign or otherwise
                  dispose of this Warrant or any shares of Common Stock to be
                  issued upon exercise hereof or conversion thereof except under
                  circumstances that will not result in a violation of the Act
                  or any state securities laws. Upon exercise of the Warrant,
                  the Holder shall, if requested by the Company, confirm in
                  writing, in a form satisfactory to the Company, that the
                  shares of Common Stock so purchased are being acquired solely
                  for the Holder's own account and not as a nominee for any
                  other party, for investment, and not with a view toward
                  distribution or resale.

                           (2) If appropriate, the Warrant and any Warrants
                  issued upon exercise or substitution or upon assignment or
                  transfer pursuant to Section (a) or Section (d), as the case
                  may be, and all shares of Common Stock issued upon exercise
                  hereof or conversion thereof shall be stamped or imprinted
                  with legends setting forth the restrictions on transfer
                  arising under applicable federal and state securities laws.

         (j)      REGISTRATION RIGHTS UNDER THE SECURITIES ACT OF 1933

                           (1) Commencing on the effective date of the first
                  registration statement for a public offering of securities of
                  the Company, the Company shall advise the Holder of the
                  Warrant or of the Warrant Shares or any then Holder of
                  Warrants or Warrant Shares (such persons being collectively
                  referred to herein as "Holders") by prompt written notice
                  prior to the filing of any registration statement or
                  post-effective amendment thereto ("Registration Statement")
                  under the Securities Act of 1933, as amended (the "Act"),
                  covering an underwritten public offering of equity securities
                  of the Company solely for cash in excess of $1,000,000 (other
                  than a Registration Statement initiated by a holder on Form
                  S-3, a registration relating solely to the sale of securities
                  to participants in a Company stock option, stock purchase or
                  similar plan or a SEC Rule 145 transaction, a registration on
                  any form which does not include substantially the same
                  information as would be required to be included in a
                  registration statement covering the sale of the Registrable
                  Securities (as defined in the Second Restated Investors'
                  Rights Agreement dated May 25, 1999, between the Company and
                  the investors signatory thereto) or a registration in which
                  the only Common Stock being registered in Common Stock
                  issuable upon conversion of debt securities that are also
                  being registered) and shall register in any such Registration
                  Statement the number of Warrant Shares that the Holder shall
                  notify the Company it desires to register and shall include in
                  any such Registration Statement such

                                       11





                  information as may be required to permit a public offering of
                  such Warrant Shares by the Company's underwriter(s). The
                  Company shall supply prospectuses and other documents as the
                  Holder may reasonably request in order to facilitate the
                  public sale or other disposition of the Warrant Shares. The
                  Company shall bear the entire cost and expense of a
                  registration of securities initiated by it under this Section
                  (j)(1). The Holder shall, however, bear the fees of its own
                  counsel and any transfer taxes and underwriting discounts or
                  commissions applicable to the Warrant Shares sold by it. The
                  Company may include other securities in any such registration
                  statement. The Company shall do any and all other acts and
                  things which may be necessary or desirable to enable the
                  Holder to consummate the public sale or other disposition of
                  the Warrant Shares, and furnish indemnification in the manner
                  as set forth in Paragraph (2) (a) of this Section (j), but
                  shall not be required to qualify as a foreign corporation to
                  qualify the Warrant Shares for sale under the securities laws
                  of any state. The Holder shall furnish information and
                  indemnification as set forth in Paragraph (2) (b) of this
                  Section (j). All decisions as to whether and when to proceed
                  with any Registration Statement shall be made solely by the
                  Company.

                           Notwithstanding the foregoing paragraph, in the event
                  that there is an underwritten offering of the Company's
                  securities offered pursuant to said registration statement
                  pursuant to the immediately preceding Paragraph, the
                  underwriter(s) shall have the right to refuse to permit any
                  Warrant Shares, or to limit the amount of Warrant Shares, to
                  be sold by the Holder to such underwriter(s) as such
                  underwriter(s) may determine in its discretion, and the Holder
                  shall refrain from selling such remainder of its Warrant
                  Shares covered by such registration statement for a period not
                  exceeding 180 days following the effective date and shall also
                  refrain at any time when notified by the Company that an
                  amendment or supplement to the prospectus is required. The
                  Company shall not be obligated to keep any Registration
                  Statement effective for a total of more than 120 days or until
                  the distribution contemplated in the Registration Statement
                  has been completed, whichever occurs first.

                           2(a) Whenever pursuant to this Section (j) a
                  Registration Statement relating to the Warrant Shares is filed
                  under the Act, amended or supplemented, the Company will
                  indemnify and hold harmless each Holder of Warrant Shares
                  covered by such Registration Statement, amendment or
                  supplement (such Holder being hereinafter called the
                  "Distributing Holder"), and each person, if any who controls
                  (within the meaning of the Act) the Distributing Holder,
                  against any losses, claims, damages or liabilities, joint or
                  several, to which the Distributing Holder or any such
                  controlling person may become subject, under the Act or
                  otherwise, insofar as such losses, claims, damages or
                  liabilities (or actions in respect thereof) arise out of or
                  are based upon any untrue statement or alleged untrue
                  statement of any material fact contained in any such
                  Registration Statement or any preliminary prospectus or final
                  prospectus constituting a part thereof or any amendment or
                  supplement thereto, or

                                       12





                  arise out of or are based upon the omission to state therein a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading; and will reimburse
                  the Distributing Holder and each such controlling person for
                  any legal or other expenses reasonably incurred by the
                  Distributing Holder and each controlling person for any legal
                  or other expenses reasonable incurred by the Distributing
                  Holder or such controlling person or underwriter in connection
                  with investigating or defending any such loss, claim, damage,
                  liability or action; provided, however, that the Company will
                  not be liable in any such case to the extent that any such
                  loss, claim, damage or liability arises out of or is based
                  upon an untrue statement or alleged untrue statement or
                  omission or alleged omission made in said Registration
                  Statement, preliminary prospectus, final prospectus or
                  amendment or supplement, in reliance upon and in conformity
                  with written information furnished by the Distributing Holder
                  or underwriter for use in the preparation thereof.

                           (b) The Distributing Holder will indemnify and hold
                  harmless the Company, each of its directors, each of its
                  officers who have signed said Registration Statement and such
                  amendments and supplements thereto, each person, if any, who
                  controls the Company (within the meaning of the Act) and the
                  Company's underwriter(s) and each person, if any, who controls
                  such underwriter(s) (within the meaning of the Act) against
                  any losses, claims, damages or liabilities to which the
                  Company or any such director, officer, underwriter or
                  controlling person may become subject, under the Act or
                  otherwise, insofar as such losses, claims, damages or
                  liabilities arise out of or are based upon any untrue or
                  alleged untrue statement of any material fact contained in
                  said Registration Statement, preliminary prospectus, final
                  prospectus, or amendment or supplement, or arise out of or are
                  based upon the omission or the alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements therein not misleading, in
                  each case to the extent, but only to the extent that such
                  untrue statement or alleged untrue statement or omission or
                  alleged omission was made in said Registration Statement,
                  preliminary prospectus, final prospectus or amendment or
                  supplement, in reliance upon and in conformity with written
                  information furnished by such Distributing Holder for use in
                  the preparation thereof; and will reimburse the Company or
                  underwriter or any such director, officer or controlling
                  person for any legal or other expenses reasonably incurred by
                  them in connection with investigating or defending any such
                  loss, claim, damage, liability or action.

                           (c) Promptly after receipt by an indemnified party
                  under this Paragraph 2 of notice of the commencement of any
                  action, such indemnified party will, if a claim in respect
                  thereof is to be made against any indemnifying party, give the
                  indemnifying party notice of the commencement thereof; but the
                  omission so to notify the indemnifying party will not relieve
                  it from any liability which it may have to any indemnified
                  party otherwise than under this Paragraph 2.


                                       13





                           (d) In case any such action is brought against any
                  indemnified party, and it notifies an indemnifying party of
                  the commencement thereof, the indemnifying party will be
                  entitled to participate in, and, the extent that it may wish,
                  jointly with any other indemnifying party similarly notified
                  to assume the defense thereof, with counsel reasonably
                  satisfactory to such indemnified party, and after notice from
                  the indemnifying party to such indemnified party of its
                  election so to assume the defense thereof, the indemnifying
                  party will not be liable to such indemnified party under this
                  Paragraph 2 for any legal or other expenses subsequently
                  incurred by such indemnified party in connection with the
                  defense thereof other than reasonable costs of investigation.

                           (e) The Company's agreements with respect to Warrant
                  Shares in this Section (j) shall continue in effect regardless
                  of the exercise of the Warrant; provided, however, that the
                  Holder's rights under this Section (j) may not be assigned
                  without the prior written consent of the Company.

         (k)      RIGHT TO CONVERT WARRANT INTO COMMON STOCK.

                           (1) RIGHT TO CONVERT. The Holder shall have the right
                  to require the Company to convert this Warrant provided in
                  this Section (1), into common stock (the "Net Conversion
                  Right"). Upon exercise of the Net Conversion Right, the
                  Company shall deliver to the Holder (without payment by the
                  Holder of any Exercise Price or of any other cash or
                  consideration) that number of shares of Common Stock equal to
                  the quotient obtained by dividing (x) the value of this
                  Warrant at the time the Conversion Right is exercised
                  (determined by subtracting the aggregate Exercise Price in
                  effect immediately prior to the exercise of the Conversion
                  Right from the aggregate fair market value of the shares of
                  Common Stock issuable upon exercise of this Warrant
                  immediately prior to the exercise of the Conversion Right) by
                  (y) the fair market value of one share of Common Stock
                  immediately prior to the exercise of the Conversion Right.

                           (2) METHOD OF EXERCISE. The Net Conversion Right may
                  be exercised by the Holder by the surrender of this Warrant at
                  the principal office of the Company together with a written
                  statement specifying that the Holder thereby intends to
                  exercise the Net Conversion Right. Certificates for the shares
                  of Common Stock issuable upon exercise of the Net Conversion
                  Right shall be delivered to the Holder within five (5) days
                  following the Company's receipt of this Warrant together with
                  the aforesaid written statement.

                           (3) DETERMINATION OF FAIR MARKET VALUE. For purposes
                  of this Section (f), fair market value of a share of Common
                  Stock as of a particular date (the "Determination Date") shall
                  be determined in accordance with Section (c) of this Warrant.

                                       14






         (l) AMENDMENTS. Neither the Warrant nor any term hereof may be changed,
waived, discharged or terminated without the prior written consent of the
Holder.

         (m) NO IMPAIRMENT. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Warrant and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of any
Holder.

         (n) GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the State of Delaware.

         (o) NOTICES. All notices and other communications required or permitted
hereunder shall be in writing and shall be mailed by first class mail, postage
prepaid, addressed (a) if to the Holder, to BT Alex. Incorporated, One South
Street, Baltimore, Maryland 21202, Attention: Donald D. Notman, Jr., or (b) if
