                                    AGREEMENT

                  AGREEMENT dated as of August 1, 2001 (the "Agreement"),
between BlueStone Capital Corp., ("BlueStone"), a New York corporation
("BlueStone") and HealthStar Corp. ("HealthStar"), on the one hand, and Shochet
Securities Inc., a Florida corporation ("Shochet") and Shochet Holding Corp.
("Shochet Holding" and, together with Shochet, the "Shochet Parties"), on the
other hand.

                              W I T N E S S E T H :

                WHEREAS, Shochet desires to transfer and assign to BlueStone,
and BlueStone desires to purchase from Shochet, the Accounts (defined below),
the Shochet Persons (defined below) and such other assets as are fully set forth
herein, upon the terms and conditions herein contained;

                NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements set forth herein and for other good and valuable
consideration, the receipt and sufficiency of which are hereby mutually
acknowledged, and intending to be legally bound hereby, the parties hereto do
hereby agree as follows:

        1.      Closing. The closing of the transactions set forth herein (the
"Closing") shall take place at the offices of Blank Rome Tenzer Greenblatt LLP,
405 Lexington Avenue, New York, NY 10174 at 10:00 A.M., local time, on the fifth
business day following the day on which the last to be fulfilled or waived of
the conditions set forth in Section 25 and 26 have been fulfilled or waived, or
at such other time, date and/or place as may be agreed upon by the parties
hereto. The date on which the Closing occurs is hereinafter referred to as the
"Closing Date."

        2.      Transfer of Accounts.

                2.1. At the Closing, Shochet will transfer, all of its right,
title and interest in the Accounts, and all customer and operational files,
including customer account agreements, including, without limitation,
arbitration agreements, option agreements and margin agreements, relating to the
Accounts (the "Transferred Files"), provided that Shochet shall be entitled to
access to the Transferred Files during regular business hours upon reasonable
notice to BlueStone. Shochet will retain all corporate and accounting files
relating to the Accounts, including files relating to past trading history of
the Accounts and files relating to accounts that do not constitute Accounts (the
"Retained Files"), provided that BlueStone shall be entitled to access to the
Retained Files during regular business hours upon reasonable notice to Shochet.
At BlueStone's option, Shochet will cause BNY Clearing Services LLC to effect an
electronic, negative transfer of the Accounts to BlueStone on a tape-to-tape
basis. In the event that either party requires access to any such files retained
by the other party in connection with an audit by any regulatory authority, the
other party shall accommodate the party seeking access to enable it to comply
with such audit, without material interference with the other party's
operations.

                2.2. The term "Accounts" means all of the securities brokerage
accounts of the retail and institutional clients of Shochet as of the date of

<Page>

this Agreement, except those accounts for which Roger Gladstone, David Greenberg
or Andrew Lockwood is the designated account representative (which accounts are
set forth on Schedule 2 attached hereto) unless Messrs. Gladstone, Greenberg or
Lockwood shall become employed by BlueStone following the Closing. Shochet
represents that it has previously provided BlueStone with a true, correct and
complete list of all of the securities brokerage accounts of the retail and
institutional clients of Shochet as of the date of this Agreement.

        2.3.    As soon as practical, Shochet and BlueStone shall prepare a form
of letter to be delivered to the holders of all Accounts, advising such holders
of the transfer of the Accounts to BlueStone which shall be in form and
substance reasonably satisfactory to BlueStone and Shochet and include such
information regarding BlueStone as deemed reasonably necessary by BlueStone and
Shochet. The letter will be sent to all holders of the Accounts so as to provide
them notice at least 10 days (or such lesser number of days agreed to by
BlueStone and Shochet, or such greater number as may be required by regulatory
authorities) prior to the Closing.

        2.4.    BlueStone shall be under no obligation to accept any Accounts
which it believes to be unsuitable for any reason whatsoever, including, without
limitation, any margin account, any Account in a state in which BlueStone is not
registered or any Account with what BlueStone deems to be an excessive debit
balance. BlueStone will not be responsible for any margin or debit balances in
any of the Accounts until accepted by BlueStone.

        2.5.    Notwithstanding anything herein to the contrary BlueStone shall
have the right to return any of the Accounts to Shochet (any such Account is
referred to as a "Returned Account") on or prior to the 30th day following the
Closing Date, provided that BlueStone's reason for returning the Account(s)
relates to trades made or other events which occurred prior to the Closing Date.

        3.      Transfer of Registered Representatives and Other Personnel.

                3.1. Shochet acknowledges and agrees that BlueStone shall be
permitted (but not obligated) to offer to hire some or all of Shochet's
personnel at the time of the Closing, a list of which Shochet personnel (each, a
"Shochet Person") is set forth on Schedule 3 attached hereto. Notwithstanding
the foregoing, BlueStone shall offer employment to all of the registered
representatives set forth on Schedule 3 attached hereto, unless reasonable
objection is made based upon regulatory history. At the time of the Closing,
Shochet shall terminate each Shochet Person to be employed by BlueStone and
BlueStone shall offer to hire Shochet Persons in accordance with this Section
3.1. In accordance with its regular payroll policies and procedures, Shochet
agrees that Shochet shall be responsible for all salaries, commissions and
bonuses due to any Shochet Person through the date of termination of their
employment with Shochet. If and when such Shochet Persons are hired by
BlueStone, the salary, commission, bonus and compliance obligations of such
Shochet Persons from and after the hiring date shall be the sole responsibility
of BlueStone.

                3.2. Shochet will retain all rights it possesses under its
existing "Association Agreements" or other agreements (other than the right to
employ Shochet Persons), including, without limitation, loans, with Shochet

                                      -2-

<Page>

persons, including, without limitation, rights of indemnification and
non-solicitation; provided, however, that Shochet will not be permitted to
exercise any of such rights (including, without limitation, the right to file
claims or commence arbitration proceedings or any other actions at law or in
equity), other than rights of indemnification and rights to collect under loans
that are not forgivable by their terms and for which repayment is not linked to
continued employment or employment performance, with respect to any Shochet
Person, as long as such Shochet Person remains an employee of BlueStone or an
affiliate or successor of BlueStone. True, correct and complete copies of all
"Association Agreements" and other employment and compensation agreements
between Shochet and the Shochet Persons have previously been provided to
BlueStone.

        4.      Trademarks and Other Intellectual Property. Upon the Closing,
the Shochet Parties will transfer and assign to BlueStone all right, title and
interest to all of the trademarks, tradenames, service marks and copyrights
owned by the Shochet Parties and used by the Shochet Parties in the operation of
Shochet as a broker-dealer (including the rights to use all logos and letterhead
the URL "Shochet.com" and any other URLs used by the Shochet Parties) a complete
list of which is set forth on Schedule 4 attached hereto (the "Intangibles"), as
well as all of the Shochet Parties' right, title and interest to the corporate
name "Shochet Securities Inc." at such time as Shochet has completed all
necessary regulatory and corporate filings relating to its name change. In
addition, Shochet agrees, as soon as practicable after the Closing, to change
its corporate name to a name that does not include the word "Shochet" and to
assist BlueStone to reserve and obtain the corporate name (or, at BlueStone's
option a "d/b/a" for) "Shochet Securities Inc.", or a similar name (including,
for a partnership or limited liability company). Shochet Holding will change its
corporate name to a name that does not include the word "Shochet" within 60 days
after the Closing and until such time, shall have the right to use its corporate
name. The Shochet Parties further agree to promptly execute and file such
documents, certificates and notices reasonably requested by BlueStone to
effectuate such transfers, including, without limitation, with the United States
Patent and Trademark Office and the NASD.

        5.      Real Property and Equipment.

                5.1. Upon the Closing, Shochet will sublease or assign (or cause
to be subleased or assigned) to BlueStone all of Shochet's right, title and
interest to all properties where Shochet Persons operate or conduct retail or
institutional brokerage business prior to the date hereof (the "Shochet
Leases"), under the Shochet Leases requested to be assigned or sublet to
BlueStone on or before the Closing Date at the same rent paid by Shochet. A list
of the Shochet Leases is set forth on Schedule 5 (a) attached hereto. Shochet
will use its best efforts, with respect to those properties requested by
BlueStone, to (i) obtain any and all applicable consents necessary to sublease
or assign the Shochet Leases to BlueStone prior to the Closing, (ii) execute
assignments of the Shochet Leases in substantially the form of Exhibit A
attached hereto, and (iii) obtain landlord estoppel certificates relating to the
Shochet Leases in substantially the form of Exhibit B attached hereto (the
documents referred to in the preceding clauses (i) (ii) and (iii) collectively
referred to as the "Landlord Documents"), and will assign to BlueStone its
rights to the security deposits relating to such Shochet Leases. To the extent
that Shochet has not obtained the Landlord Documents relating to any Shochet

                                      -3-

<Page>

Lease requested by BlueStone relating to any Shochet Lease by the Closing Date,
then Shochet will sublease to BlueStone the properties relating to those Shochet
Leases for which the Landlord Documents have not been obtained, for as long as
requested by BlueStone. Shochet agrees to continue to use its best efforts to
obtain any such remaining Landlord Documents after the Closing Date. As a
condition to BlueStone accepting assignment of any Shochet Lease, BlueStone
shall receive all Landlord Documents pertaining to such Shochet Lease. If
Shochet does not deliver to BlueStone the Landlord Documents with respect to any
property subject to a Shochet Lease within 120 days of the date of this
Agreement, BlueStone shall not be obligated to accept assignment of any such
Shochet Lease.

                5.2. Upon the Closing, Shochet will transfer or assign to
BlueStone all of its furniture, fixtures and telephone and computer equipment
relating to the properties covered by the Shochet Leases (the "Shochet
Equipment") and all rights relating to the Shochet Equipment in accordance with
this Section 5, except for such furniture, fixtures and telephone and computer
equipment which are owned by Shochet Holding and not used in the operation of
Shochet (the "Shochet Holding Equipment"), provided that the value of the
Shochet Holding Equipment does not exceed 5% of all the value of the Shochet
Equipment. A list of the Shochet Equipment and leases pertaining to any Shochet
Equipment ("Shochet Equipment Leases") is set forth on Schedule 5(b) attached
hereto. Shochet will provide BlueStone with a list of the Shochet Holding
Equipment prior to the Closing Date.

                5.3. The parties will enter into an agreement prior to Closing
which grants Shochet and Shochet Holding access to use a limited amount of
office space in one or more of the properties relating to the Shochet Leases for
a limited period of time after the Closing, for a fee to be agreed upon by the
parties.

                5.4. Shochet and BlueStone will allocate rent and utility
charges relating to the properties referred to in this Section 5 as of the
Closing and will remit any amounts due as a result of such allocation at the
Closing. At the Closing, BlueStone shall pay to Shochet an amount equal to the
security deposits held by the landlords of the properties assigned or sublet to
BlueStone under Section 5.1; provided that such amount shall not exceed $65,152.
If Shochet does not obtain any of the Landlord Consents by the Closing and
BlueStone elects not to occupy or continue to occupy any such properties during
the term of such Shochet Lease, then Shochet will return that portion of the
security deposits relating to the properties for which Landlord Consents had not
been obtained by Closing to BlueStone.

        6.      Consideration. As consideration for the transactions described
in Sections 2 through 5 of this Agreement (the "Transaction"):

                6.1. Except to the extent prohibited by applicable law and
regulatory authorities, BlueStone shall pay to Shochet a cash fee (the "Fee")
equal to eight percent (8%) of Gross Revenue (defined below). The Fee shall be
payable monthly (each payment, a "Monthly Payment") within twenty (20) days of
the end of each calendar month for that portion of the Fee arising from Gross
Revenue actually received (not just earned) by BlueStone during such calendar
month (or if such 20th day is not a business day, on the next following business
day) by wire transfer to the account designated to BlueStone in writing by

                                      -4-

<Page>

Shochet from time to time. Notwithstanding anything herein to the contrary, the
maximum Fee payable by BlueStone is $2,000,000. HealthStar guarantees
BlueStone's obligation to pay the Fee.

                        (a) The term "Gross Revenue" means all cash actually
received by BlueStone, including, without limitation, gross commissions, sales
concessions and fees (before any allocation, distribution or payment thereof by
BlueStone to others) which are, during the three (3)-year period commencing as
of the Closing (subject to earlier termination if the maximum Fee is paid)
earned by BlueStone from (i) the Accounts, (ii) any new accounts for which
Shochet Persons are designated as account representatives (the "New Accounts")
and (iii) any Returned Accounts until such accounts are returned to Shochet.

                6.2. At the Closing, HealthStar will issue to Shochet 100,000
shares of HealthStar's common stock (the "Shares"). Shochet acknowledges that
the Shares are "restricted securities" within the meaning prescribed by the
Securities Act of 1933 (the "Act").

                6.3. At the Closing, HealthStar will assume Shochet's
obligations under the $500,000 principal amount subordinated note due in August
2001 issued by Shochet to Firebrand Financial Group, Inc. (the "Firebrand Note")
and will repay the principal and interest under the Firebrand Note when due.

        7.      No Assumption of Liabilities; Excluded Assets. Shochet
acknowledges that, except with respect to any obligations Shochet may have at
the Closing with respect to (i) the Firebrand Note, and (ii) the Schroder Letter
(as defined in Section 8), and other than to assume and perform Shochet's
obligations after the Closing under the Shochet Leases and the Shochet Equipment
Leases set forth on Schedule 5 attached hereto, BlueStone will not assume any
liabilities, expenses, debts or obligations of Shochet, including, without
limitation, Litigation Liabilities. "Litigation Liabilities" means debts,
obligations or liabilities arising from or relating to pending, threatened and
unasserted claims (including, without limitation, customer complaints),
litigation, legal actions, counterclaims, suits or arbitration or other legal,
administrative or tax proceedings. Shochet further acknowledges that BlueStone
will not acquire any assets of Shochet (other than the Accounts, Shochet
Persons, Shochet Equipment, Shochet Leases and Shochet Equipment Leases),
including, without limitation, Shochet's cash, securities (including marketable
securities, options, warrants and other derivative securities), goodwill and
litigation (the "Excluded Assets").

        8.      Schroeder Letter. Shochet represents and warrants to BlueStone
that Shochet entered into a clearing agreement (the "Schroder Clearing
Agreement") with Schroder & Co. Inc. in or prior to December 2000, and that the
Schroder Clearing Agreement was amended by letter dated December 13, 2000 (the
"Schroder Letter") by and among Shochet, Schroder and Salomon Brothers Holding
Company Inc. ("Salomon"). In or about January 2001, Salomon sold the clearing
operations of Schroeder to BNY Clearing Services LLC ("BNY"). The Schroder
Letter constitutes Shochet's only agreement, understanding or arrangement with,
or commitment to, Schroder and Salomon with respect to the $1.25 million payment
from Salomon to Shochet. True, correct and complete copies of the Schroder
Clearing Agreement and the Schroder Letter were previously delivered to
BlueStone. HealthStar agrees to assume the obligations of Shochet, if any, to
Salomon under the Schroder Letter and shall indemnify and hold harmless Shochet
from any liability under or arising out of the Schroeder Letter.

                                      -5-

        9.      Registration Rights.

                9.1. If, at any time following the Closing, HealthStar proposes
to prepare and file one or more registration statements or amendments, including
post-effective amendments, or supplements thereto covering any of HealthStar's
equity or debt securities to be sold by HealthStar or any of its shareholders,
other than pursuant to Form S-4 or Form S-8 or successor form (collectively, a
"Registration Statement"), it will give written notice of its intention to do so
by registered mail ("Notice"), at least ten (10) business days prior to the
filing of each such Registration Statement, to Shochet.

                9.2. Upon the written request of Shochet, made within five (5)
business days after receipt of the Notice, that HealthStar include all or a
portion of the Shochet Restricted Shares (defined below) in the proposed
Registration Statement, HealthStar shall include such shares and use its best
efforts to cause such Registration Statement to be declared effective under the
Act by the Securities and Exchange Commission ("SEC") so as to permit the public
sale by Shochet of the Shochet Restricted Shares pursuant thereto, at
HealthStar's sole cost and expense and at no cost or expense to Shochet.
However, if, in the written opinion of the HealthStar's managing underwriter, if
any, for the offering evidenced by such Registration Statement, the inclusion of
all or a portion of the Shochet Restricted Shares, when added to the securities
being registered, will exceed the maximum amount of HealthStar's securities
which can be marketed either (i) at a price reasonably related to their
then-current market value or (ii) without otherwise materially adversely
affecting the entire offering, then HealthStar may exclude from such offering
all or a portion of the Shochet Restricted Shares subject to the requirements of
Section 9.4.

                9.3. The term "Shochet Restricted Shares" shall mean all of the
Shares, provided that all or a part of the Shares shall cease to be Shochet
Restricted Shares at such time (i) such Shares are transferred, sold or
otherwise disposed of by Shochet; or (ii) registration under the Act is no
longer required for the subsequent transfer or disposition of such Shares
because they may be sold freely into the market without any volume limitations.

                9.4. If securities are proposed to be offered for sale pursuant
to such Registration Statement by other security holders of HealthStar and the
total number of securities to be offered by Shochet and such other selling
security holders (collectively the "Requesting Holders") is required to be
reduced pursuant to a request from the managing underwriter (which request shall
be made only for the reasons and in the manner set forth above in Section 9.2),
the number of securities to be offered by each Requesting Holder pursuant to
such Registration Statement shall be reduced proportionately among the
Requesting Holders.

                9.5. Notwithstanding the provisions of this Section 9,
HealthStar shall have the right at any time after it shall have given written
notice pursuant to this Section 9 (irrespective of whether any written request
for inclusion of Shochet Restricted Securities shall have already been made) to
elect not to file any such proposed Registration Statement or to withdraw the
same after its filing but prior to the effective date thereof.

                9.6.

                        (a) HealthStar shall agree to indemnify, to the full
extent permitted by law, Shochet and its officers, directors, partners, members
and agents against all losses, claims, damages, liabilities and expenses
(including reasonable attorneys' fees) caused by any untrue or alleged untrue
statement of a material fact contained in any registration statement or
prospectus or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements made therein (in the case of
a prospectus, in the light of the circumstances under which they were made) not
misleading, except insofar as the same are (i) caused by or contained in any
information supplied by Shochet, (ii) caused by Shochet's failure to deliver a
copy of the prospectus or any amendments or supplements thereto in accordance
with the requirements of the Act after HealthStar has furnished Shochet with a
copy of the same, or (iii) caused by Shochet's sale of Shochet Restricted Shares
under the Registration Statement after HealthStar notifies the Shochet that the
prospectus had been suspended or that the Registration Statement contained a
material misstatement or omission.

                        (b) Shochet agrees to indemnify (only up to an amount
equal to the proceeds it receives from the sale of Shochet Restricted Shares),
to the full extent permitted by law, HealthStar, its directors, officers and
agents and each person who controls HealthStar (within the meaning of the
Exchange Act) against any losses, claims, damages, liabilities and expenses
(including reasonable attorneys' fees) caused by any untrue or alleged untrue
statement of a material fact, contained in any registration statement or
prospectus or any omission or alleged omission of a material fact required to be
stated therein. or necessary to make the statements therein (in the case of a
prospectus, in the light of the circumstances under which they were made) not
misleading, to the extent, but only to the extent that the same are (i) caused
by or contained in any information provided by Shochet, (ii) caused by Shochet's
failure to deliver a copy of the prospectus or any amendments or supplements
thereto in accordance with the requirements of the Act after HealthStar has
furnished Shochet with a copy of the same, or (iii) caused by Shochet's sale of
Shochet Restricted Shares under the Registration Statement after HealthStar
notified Shochet that the prospectus had been suspended or that the Registration
Statement contained a material misstatement or omission.

                        (c) Any person entitled to indemnification hereunder
shall give prompt written notice to the indemnifying party after the receipt by
such person of any written notice of the commencement of any action, suit,
proceeding or investigation or threat thereof made in writing for which such
person may claim indemnification or contribution pursuant to this Agreement and,
unless in the reasonable judgment of such indemnified party a conflict of
interest exist between such indemnified party and the indemnifying party with
respect to such claim, permit the indemnifying party to assume the defense of
such claim with counsel reasonably satisfactory to such indemnified party. If
the indemnifying party is not entitled to, or elects not to, assume the defense
of a claim, it will not be obligated to pay the fees and expenses of more than
one counsel with respect to such claim. The indemnified party will not be
subject to any liability for any settlement made without its consent.

                        (d) If the indemnification provided for in this Section
from the indemnifying party is unavailable or insufficient to an indemnified
party hereunder in respect of any losses, claims, damages, liabilities or
expenses referred to therein, then the indemnifying party, in lieu of

                                      -7-

<Page>

indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party, as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and indemnified parties in connection
with the actions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations. The relative
fault of such indemnifying party and indemnified parties shall be determined by
reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact, has been made by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitations set forth in subsection (c) hereof, any legal or other fees or
expenses reasonably incurred by such party in connection with any investigation
or proceeding. The parties hereto agree that it would not be just and equitable
if contribution pursuant to this subsection (d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.

                9.7.  As a condition to the registration of any Shochet
Restricted Shares, Shochet will provide such representations as HealthStar may
reasonably request.

        10.     Monthly Reports. BlueStone shall make monthly written reports to
Shochet setting forth an accounting of the amounts payable to Shochet. Such
report shall be provided to Shochet by no later than the 20th day of the month
following the calendar month (or if such 20th day is not a business day, on the
next following business day) to which the report relates. Shochet shall have the
right, at its own expense, to inspect the data underlying the monthly written
reports solely for the purpose of determining BlueStone's compliance with
Section 6.1, provided that Shochet may not exercise this right to audit more
than two times during any twelve (12)-month period, and provided, further, that
Shochet enters into a confidentiality agreement with BlueStone in a form
reasonably acceptable to BlueStone prior to such inspection. Shochet shall
provide BlueStone prior to such inspection and its professional advisors with
reasonable prior written notice of its intention to audit, and shall conduct
such audit during normal business hours. Shochet shall make reasonable efforts
not to disturb BlueStone's operations during the audit. In no event shall
Shochet have the right to access BlueStone's books, records or computer files or
any other information relating to customer accounts, other than the Accounts,
New Accounts and Returned Accounts, or any other matters.

        11.     Restrictions on Transfer of Accounts and New Accounts by
BlueStone. BlueStone agrees that it will not transfer any of the Accounts or New
Accounts (unless directed by the client or required by law, rule, regulation,
consent, order or decree or any government agency or regulatory authority), in
connection with a sale of all or substantially all of its assets or otherwise,
during the three (3)-year period following the Closing, unless the party to
which the Accounts and New Accounts are transferred assumes BlueStone's
obligations under Sections 6.1 and 10 and this Section 11.

years from the date hereof.

hereto will issue a joint press release announcing the Transaction.

the Transaction that will be the responsibility of the other party.

affiliates in the continued collection from Leila Shuminer, a Shochet Person,
solely by withholding amounts from her pay and remitting same to Shochet, of
aggregate payments in the amount of $175,000 (less amounts collected by Shochet
prior to the Closing Date, of which amount Shochet will notify BlueStone in
writing on the Closing Date) which she has agreed to pay Shochet in connection
with the settlement of certain claims made against Shochet and her, if and only
to the extent that Leila Shuminer specifically consents in writing to such
withholding and payments by BlueStone on her behalf to Shochet in a form
satisfactory to BlueStone, in its sole discretion.

and to the best knowledge of Shochet, neither it nor any other party is in
default thereunder and, to the best knowledge of Shochet, no event has occurred
which, with the lapse of time or the giving of notice, or both, would constitute
a default thereunder. Shochet represents and warrants that it is current in all
payments under the terms of the Shochet Leases and Shochet Equipment Leases,
except to the extent of any amounts to be paid to BlueStone pursuant to Section

have infringed or is infringing upon the rights of others with respect to the
Intangibles; Shochet has not received any notice of conflict with the asserted
rights of others with respect to the Intangibles (and Shochet knows of no basis
therefor); and no others have infringed upon the Intangibles.

        17.     Investment Representations and Warranties of Shochet.

                17.1. Shochet understands that the Shares are "restricted

                PLEDGED, TRANSFERRED, DISTRIBUTED OR OTHERWISE DISPOSED OF IN
                ANY MANNER UNLESS THEY ARE REGISTERED UNDER THE ACT AND ANY
                APPLICABLE SECURITIES LAWS, OR UNLESS THE REQUEST FOR TRANSFER
                IS ACCOMPANIED BY AN OPINION OF COUNSEL, REASONABLY
                SATISFACTORY TO THE COMPANY, STATING THAT SUCH TRANSFER IS
                EXEMPT FROM REGISTRATION UNDER THE ACT AND ANY APPLICABLE

                17.3. Shochet acknowledges that representatives of Shochet have

conditions of this Agreement; and all of such questions have been answered to
the satisfaction of Shochet's representatives.

                17.4. Shochet represents that it is an "accredited investor" as
defined in Rule 501(a) promulgated under the Act and that its representatives
are sophisticated investors familiar with the type of risks inherent in the
acquisition of securities such as the Shares and that, by reason of its
representatives knowledge and experience in financial and business matters in
general, and investments of this type in particular, its representatives are
capable of evaluating the merits and risks of an investment in the Shares.

                17.5. Shochet is able to bear the economic risk of an investment
in the Shares, including, without limiting the generality of the foregoing, the
risk of losing part or all of Shochet's investment in the Shares.

                17.6. Shochet is acquiring the Shares for its own account and
for the purpose of investment and not with a view to, or for resale in
connection with, any distribution within the meaning of the Act or any other

of the indemnifying party. So long as the indemnifying party or parties are
contesting any such claim in good faith, the indemnified party or parties shall
not pay or settle any such claim; provided, however, that notwithstanding the
foregoing, the indemnified party or parties shall have the right to pay or
settle any such claim at any time, provided that in such event they shall waive
any right of indemnification therefor by the indemnifying party or parties. If
the indemnifying party or parties do not make a timely election to undertake the
good faith defense or settlement of the claim as aforesaid, or if the
indemnifying parties fail to proceed with the good faith defense or settlement
of the matter after making such election, then, in either such event, the
indemnified party or parties shall have the right to contest, settle or
compromise the claim.

                        (d) Regardless of which party is controlling the defense
of any claim, each party shall act in good faith and shall provide reasonable
documents and cooperation to the party handling the defense.

                        (e) Notwithstanding anything to the contrary in this
Section 22, in no event shall (x) the indemnification by Shochet or Shochet
Holding under clause (iii) of Section 22(a) or (y) the indemnification by
BlueStone or HealthStar under clause (iii) of Section 22(b) of this Agreement
exceed $500,000 plus the market value of the Shares on the Closing Date, based
on the last sale price of HealthStar's common stock on the Closing Date.

        23.     Survival of Representations and Warranties. Each of the parties
hereto hereby agrees that the representations and warranties made by or on
behalf of each party in this Agreement or in any document or instrument
delivered pursuant hereto shall survive the execution hereof for a period of two
(2) years.

        24.     Conduct of Business. Prior to the Closing Date, (i) Shochet will
conduct its business only in the ordinary course, (ii) Shochet will use its best
efforts to maintain the value of its business as a going concern, (iii) Shochet
will not sell, transfer or otherwise dispose of any of the assets without the
prior written consent of BlueStone, (iv) Shochet will not transfer any of the
Accounts without the prior written consent of BlueStone, except upon receipt of
instructions from a client, and (v) Shochet will not terminate any of the
Shochet Leases set forth on Schedule 5(a) attached hereto without the prior
written consent of BlueStone.

        25.     Conditions to Obligations of BlueStone and HealthStar. The
obligations of BlueStone and HealthStar shall be subject to the satisfaction of
each of the following conditions, or written waiver by BlueStone or HealthStar
thereof:

                25.1. Shochet and Shochet Holding shall have performed in all
material respects each of the agreements and covenants made by them in this
Agreement and required to be performed on or prior to the Closing Date;

                25.2.  The representations and warranties of Shochet and Shochet
Holding contained herein shall be true, complete and correct in all material

<Page>

                25.3. There exists no order, judgment, decree, injunction,
consents, citations, rulings, determinations, verdicts ("Order") entered, issued
or made, to which the Accounts, Shochet Persons, Intangibles, properties
relating to the Shochet Leases or the Shochet Equipment are subject or which
restrains or prohibits the Transaction, and no claim, suit, action, inquiry,
investigation or proceeding in which it will be, or it is, sought to restrain,
prohibit or change the terms of or obtain damages or other relief in connection
with this Agreement or the Transaction, has been instituted or threatened by any
person or entity, and which, in the reasonable judgment of BlueStone (based on
the likelihood of success and material consequences of such claim, suit, action,
inquiry or proceeding), makes it impossible to proceed with the consummation of
the Transaction in all material respects;

                25.4. BlueStone and HealthStar shall have received an opinion of
Graubard Miller, counsel to Shochet and Shochet Holding in substantially the

                25.5. Shochet shall have provided BlueStone and HealthStar with

Transaction shall have been obtained by the Closing Date.

        26.     Conditions to Obligations of Shochet and Shochet Holding. The
obligations of Shochet and Shochet Holding shall be the subject of the
satisfaction of each of the following conditions, or written waiver by Shochet
or Shochet Holding thereof:

                26.1. Each of BlueStone and HealthStar shall have performed in
all material respects each of the agreements and covenants made by it in this
Agreement and required to be performed on or prior to the Closing Date;

                26.2. The representations and warranties of each of BlueStone
and HealthStar contained herein shall be true, complete and correct in all
material respects at and as of the Closing Date, as if made at such date, except
for the passage of time;

                26.3. There exists no Order entered, issued or made, which
restrains or prohibits the Transaction, and no claim, suit, action, inquiry,
investigation or proceeding in which it will be, or it is, sought to restrain,
prohibit or change the terms of or obtain damages or other relief in connection
with this Agreement or the Transaction, has been instituted or threatened by any
person or entity, and which, in the reasonable judgment of Shochet and Shochet
Holding (based on the likelihood of success and material consequences of such
claim, suit, action, inquiry or proceeding), makes it impossible to proceed with
the consummation of the Transaction in all material respects;

                26.4. Shochet and Shochet Holding shall have received an opinion
of Blank Rome Tenzer Greenblatt LLP, counsel to each of BlueStone and HealthStar
in substantially the form of Exhibit E attached hereto; and

                27.1. This Agreement may be terminated at any time prior to the
Closing:

                      (a)  by the mutual written consent of the Shochet Parties
and BlueStone and HealthStar; or

                       (b) by either side if no Closing has occurred within 90
days of the date hereof; or

                       (c) by either side if the any party on the other side is
in material breach of this Agreement.

                27.2. Upon the termination of this Agreement in accordance with
the terms hereof, it shall forthwith become void and of no further force and
effect, except for the provisions of Sections 30.6 and 30.7 hereof; provided,
however, that no such termination shall be deemed to relieve any party hereto of
any liability for its breach of any of the terms and provisions hereof.

        28.     Effectiveness of Agreement. This Agreement shall be effective as
of the date hereof. It is recognized that a certain period of time will be
required for the Shochet Persons to be transferred on the books of the NASD and
the Accounts to be transferred by Shochet's clearing agent and accepted by
BlueStone. Accordingly, Shochet agrees that BlueStone shall have no supervisory
responsibility over such Shochet Persons or any liability with respect to such
Accounts, including, without limitation, for margin or debit balances in such
Accounts, until they are so transferred and accepted by BlueStone.

        29.     Necessary Action. Each party hereto agrees to use all reasonable
efforts to take or cause to be taken all actions, and to do or cause to be done,
and to assist and cooperate with the other parties in doing, all things
necessary, proper or advisable to expeditiously consummate and make effective
the transactions contemplated by this Agreement, including, without limitation,
the making of any filings with, and the procurement of any authorizations and
consents from, regulatory agencies or other persons or entities.
