                         COMMON STOCK PURCHASE AGREEMENT

         THIS AGREEMENT (this "AGREEMENT") is made this 24th day of July, 2000
by and between WORLDGATE COMMUNICATIONS, INC., a Delaware corporation (the

         WHEREAS, the Company wishes to issue and sell to the Purchaser shares
of common stock, par value $.01 per share, of the Company (the "COMMON SHARES")
as provided herein; and

         WHEREAS, the Purchaser wishes to purchase the Common Shares on the
terms and subject to the conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained in this Agreement, and intending to be
legally bound hereby, the parties agree as follows:

                                   ARTICLE 1

                   (a)  Upon the terms and subject to the conditions of this
Agreement, on the Closing Date (as hereinafter defined), the Company shall
issue, sell and deliver to the Purchaser, and the Purchaser shall purchase and
take from the Company, 500,000 Common Shares (the "SHARES").

                   (b)  The purchase price for each Share shall be $16.02. The
aggregate purchase price for all of the Shares to be purchased by the Purchaser
herein is sometimes referred to herein as the "PURCHASE PRICE."

         1.2       CLOSING.

                   (a)  The closing of the purchase and sale of the Shares (the

<PAGE>


                   (b)  At the Closing, the Company shall deliver, or shall
instruct its transfer agent to deliver, to the Purchaser a stock certificate or

the Purchaser will deliver to the Company the Purchase Price therefor, by wire
transfer of immediately available funds in U.S. dollars to a bank in the United
States specified by the Company for the account of the Company.

                                   ARTICLE 2
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to the Purchaser as follows:

         2.1       ORGANIZATION AND GOOD STANDING. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite power and authority, and all necessary
licenses and permits, to own and lease its properties and assets and to conduct
its business as now conducted. Each Subsidiary (as defined in SECTION 2.10) is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and has all requisite power and
authority, and all necessary licenses and permits, to own and lease its
properties and assets and to conduct its business as now conducted. The Company
and its Subsidiaries are each qualified to do business as a foreign corporation
and are each in good standing in all states where the conduct of their
respective businesses or their ownership or leasing of property requires such
qualification, except where the failure to so qualify would not have a material
adverse effect on the Company's or any Subsidiary's business, properties,
assets, prospects, operations or condition (financial or otherwise).

         2.2       AUTHORIZATION. The Company has all requisite power and
authority to execute and deliver this Agreement and to carry out the
transactions contemplated hereby. The execution, delivery and performance by the
Company of this Agreement have been duly authorized by all requisite corporate
action, and this Agreement has been duly executed and delivered by the Company
and constitutes the valid and binding obligation of the Company, enforceable
against the Company in accordance with its terms, except as such enforcement may
be limited by bankruptcy, insolvency, moratorium, reorganization and other
similar laws relating to or affecting the enforcement of creditors' rights
generally, and except that the availability of specific performance, injunctive
relief or other equitable remedies is subject to the discretion of the court
before which any such proceeding may be brought.

         2.3       COMPLIANCE WITH LAW AND OTHER INSTRUMENTS. Neither the
Company nor any of its Subsidiaries is in violation or default of any provision
of its Certificate of Incorporation or Bylaws, each as amended and in effect on
and as of the Closing. To the Company's knowledge, neither the Company nor any
of its Subsidiaries is in violation in any material respect of any material
statute, rule, regulation, order or restriction of any state, local or federal
government or any instrumentality or agency thereof in respect of the conduct of
its business or the ownership of its properties. Neither the Company nor any of
its Subsidiaries is in violation or default of any provision of any instrument,
mortgage, deed of trust, loan, contract, commitment, judgment, decree, order or
obligation to which it is a party or by which it or any of its properties or
assets are bound which would have a Company Material Adverse Effect. A "COMPANY
MATERIAL


                                      -2-

<PAGE>


ADVERSE EFFECT" means any fact, condition, event, development or occurrence
which, individually or when taken together with all other such facts,
conditions, events, developments or occurrences, could reasonably be expected to
have a material adverse effect on the condition (financial or otherwise),
business, prospects, property, assets or liabilities of the Company or its
Subsidiaries, taken as a whole. The execution, delivery and performance of and
compliance with this Agreement, and the issuance and sale of the Shares, will
not violate any provision of law, any rule or regulation of any governmental
authority, or any judgment, decree or order of any court binding on the Company,
and will not conflict with or result in any breach of any of the terms,
conditions or provisions of, or constitute a default, with or without the
passage of time or giving of notice, require any consent or waiver under any
such provision (other than any consents or waivers that have been obtained), or
result in the creation of any lien, security interest, charge or encumbrance
upon, any of the properties, assets or outstanding stock of the Company or any
of its Subsidiaries under their respective certificates of incorporation or
articles of incorporation, as applicable, or bylaws or other organizational
documents, or any indenture, mortgage, lease, agreement or other instrument to
which the Company or any of its Subsidiaries is a party or by which any of them
or any of their respective properties is bound.

         2.4       CAPITALIZATION.

                   (a)  The authorized capital stock of the Company consists of
50,000,000 Common Shares and 13,500,000 shares of preferred stock, par value
$.01 per share (the "PREFERRED STOCK"). As of July 21, 2000, (i) 21,704,009
Common Shares have been duly and validly issued and are outstanding, (ii)
3,200,000 Common Shares are reserved for issuance under the Company's Amended
and Restated 1996 Stock Option Plan, as amended to date (the "OPTION PLAN"),
(iii) 594,743 Common Shares are reserved for issuance pursuant to outstanding
warrants issued by the Company, and (iv) no shares of Preferred Stock are issued
and outstanding. All outstanding shares have been issued in compliance with
state and federal securities laws.

                   (b)  Except as described in the SEC Reports, this SECTION 2.4
or in SCHEDULE 2.4, there are no outstanding securities convertible into or
exchangeable for the capital stock of the Company or options, warrants or other
rights to purchase or subscribe for any capital stock of the Company or
contracts, commitments, agreements, understandings or arrangements of any kind
to which the Company is a party relating to the issuance of any capital stock of
the Company, any such convertible or exchangeable securities or any such
options, warrants or rights.

                   (c)  As a result of the sale of an aggregate of 1,531,211
shares on the date hereof to the Purchaser pursuant to this Agreement and to
certain other purchasers pursuant to the Common Stock Purchase Agreements (as
defined in Section 2.24), unless waived by the holders thereof, the exercise
price of the warrants issued by the Company to each of Ampal American-Israel
Corporation and Strong River Investment, Inc. (collectively, the "WARRANT
HOLDERS") shall be decreased from $16.50 per share to $16.1156074 per share and
the number of shares purchasable shall be increased from 165,745 to 169,698. In
the event that the Company issues an MSO Warrant (as defined in Section 2.16) to
ACC Operations, Inc. on the date hereof to purchase 500,000 shares of the
Company at an exercise price of $12.39, unless waived by the Warrant Holders,
the exercise price of the warrants issued by the Company to each of the Warrant
Holders shall be further decreased to $15.9458638 per share and the number of
shares purchasable shall be increased to 171,504.

<PAGE>


         2.5       VALID ISSUANCE OF THE SHARES. The Shares when issued, sold
and delivered to the Purchaser in accordance with this Agreement will be duly
and validly issued, fully paid, non-assessable and free and clear of all liens
and encumbrances (other than restrictions on transfer under applicable federal
and state securities laws). No preemptive rights are applicable with respect to
the issuance of the Shares.

         2.6       CONSENTS AND APPROVALS. Except for compliance with the
notification or other requirements of the HSR Act, if required, and Nasdaq and
the rules and regulations promulgated thereunder and filings under federal and
applicable state securities laws, no permit, consent, approval or authorization
of, or declaration to or filing with, any federal, state, local or foreign
governmental or regulatory authority or any other individual, partnership,
corporation, business trust, joint stock company, trust, unincorporated
association, joint venture or other entity of whatever nature (each a "PERSON"),
not made or obtained, is required in connection with the execution or delivery
of this Agreement by the Company, the offer, issuance, sale or delivery of the
Shares or the carrying out by the Company of the other transactions contemplated
hereby.

         2.7       PRIVATE OFFERING. Assuming the accuracy of the Purchaser's
representations and warranties contained in ARTICLE 3 herein, the offer,
issuance and delivery to the Purchaser pursuant to the terms of this Agreement
of the Shares are exempt from registration under the Securities Act of 1933, as
amended (the "SECURITIES ACT").

         2.8       ADDITIONAL SECURITIES LAW MATTERS. None of the Company or any
of its Affiliates (as defined herein), or any Person acting on its or their
behalf, has offered to sell or sold any Common Shares by means of any form of
general solicitation or general advertising within the meaning of Rule 502(c)
under the Securities Act that would subject the issuance and sale of the Shares
to the registration provisions of the Securities Act. For purposes hereof,
"AFFILIATE" means any Person directly or indirectly controlled by, controlling
or under common control with another Person. For purposes of this definition,
"CONTROL" means the power to direct the management of the Person in question.

         2.9       CERTIFICATE OF INCORPORATION AND BYLAWS. The Company's
Certificate of Incorporation and Bylaws, each as amended to date and attached as
an exhibit to the Company's Form 10-Q Report for the quarter ended March 31,

effect.

         2.10      SUBSIDIARIES. Except as set forth on SCHEDULE 2.10, the
Company does not presently own or control, directly or indirectly, any interest
in any other corporation, association or other business entity. The entities
listed on SCHEDULE 2.10 (collectively, the "SUBSIDIARIES") are wholly owned by
the Company. The Company is not a participant in any joint venture, partnership
or similar arrangement in which the Company owns any equity interest in such
joint venture, partnership or similar arrangement.

"COMMISSION") since April 15, 1999. The SEC Reports when filed complied in all

"EXCHANGE ACT"), and all applicable legal requirements and did not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading.

                   (c)  When the MSO Registration Statement, as such may be
amended from time to time, is declared effective by the Commission, such MSO
Registration Statement will comply in all material respects with the Securities
Act, and all applicable legal requirements and will not contain any untrue
statement of a material fact or omit to state any material fact required to be

SHEET DATE") reflected all material liabilities and obligations of the Company
and of each Subsidiary, whether accrued, contingent or otherwise, as of the date
thereof, in each case, to the extent required by United States generally
accepted accounting principles, consistently applied ("GAAP").

                   (b)  Except as disclosed in the Registration Statement, since
the Balance Sheet Date, the Company and its Subsidiaries have not been subject
to any events or conditions of any character that have had a Company Material
Adverse Effect.

                   (c)  Since the Balance Sheet Date, there has been no

                   (d)  Except as disclosed in the Registration Statement and
since the date of the March Balance Sheet, neither the Company nor any of its
Subsidiaries has incurred any debt for borrowed money or any material
liabilities or obligations except (i) the liabilities and obligations set forth
on the March Balance Sheet, (ii) liabilities and obligations which have been
incurred subsequent to the March Balance Sheet Date in the ordinary course of
business of the same character as those set forth on the March Balance Sheet,
and (iii) liabilities, obligations and contingencies which are of a nature not
required to be reflected in the consolidated financial statements of the Company
and its Subsidiaries prepared in accordance with generally accepted accounting
principles consistently applied.

         2.13      PROCEEDINGS AND LITIGATION. Except as set forth in the SEC
Reports, there is no material action, suit, proceeding or investigation pending
or, to the best of the Company's knowledge, currently threatened before any
arbitrator, court, administrative agency or other governmental body (nor, to
best of the Company's knowledge, is there any basis for any such action, suit,
proceeding or investigation) (i) against or affecting the Company or (ii)
seeking to restrain, prevent or change the transactions contemplated hereby or
otherwise questioning the validity or legality of such transactions. Neither the

Reports, the Company owns or has the rights to all material patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information,
proprietary rights and processes necessary for its business as now conducted and
as proposed to be conducted. Except as set forth in the SEC Reports, to the best
of the Company's knowledge, the use of such intellectual property in its
business does not conflict with or infringe the rights of others except where it
would not have a Company Material Adverse Effect. To the best knowledge of the
Company (without having undertaken an independent investigation), the Company
has not violated and, by conducting its business after the Closing Date in a
manner substantially identical to the manner of conducting its business prior to
the Closing Date, the Company has not infringed and does not foresee any
potential infringement of any of the patents, trademarks, service marks, trade
names, copyrights or trade secrets or other proprietary rights of any other
Person nor have any claims been asserted, and no claims are pending, or to the
Company's best knowledge threatened, regarding any such alleged infringement.

subsidiaries to any third party.

<PAGE>


referred to herein as the "REGISTRATION RIGHTS AGREEMENTS"), the Company is
under no contractual obligation to register under the Securities Act any of its

obligations under the Registration Rights Agreements.

         2.17      BROKER OR FINDER. No Person acting on behalf of Company or
any of its Affiliates or under the authority of any of the foregoing is or will

fee, directly or indirectly, from any of such parties in connection with any of
the transactions contemplated by this Agreement.

         2.18      DISCLOSURE. No representation or warranty by the Company
contained in this Agreement, or in any written statement, exhibit or certificate
furnished to the Purchaser pursuant to this Agreement at Closing contains any
untrue statement of a material fact or, when taken together, omits to state a
material fact necessary to make the statements made herein or therein, in light
of the circumstances under which they were made, not misleading.

         2.19      PERMITS. The Company and each of its Subsidiaries have all
franchises, permits licenses and any similar authority (collectively, the
"AUTHORIZATIONS") necessary for the conduct of their respective businesses as
presently being conducted, except for any such Authorizations as to which,
individually or in the aggregate, the failure to possess could not reasonably be
expected to have a Company Material Adverse Effect, and the Company believes it
can obtain, without undue burden or expense, any similar Authorization for the
conduct of its business as planned to be conducted. The Company is not in
default in any material respect under any Authorization.

         2.20      ENVIRONMENTAL AND SAFETY LAWS. To the best of the Company's
knowledge, neither the Company nor any of its Subsidiaries is in violation, or
has engaged in activities that would result in a violation, of any applicable
material statute, law or regulation relating to the environment or occupational
health and safety, and to the best of the Company's knowledge, no material
expenditures are or will be required in order to comply with any such existing
statute, law or regulation. There has been no complaint, notice of violation,
investigation or report received by the Company or its Subsidiaries relating to
any alleged violation of any such applicable statute, law or regulation, and
there is no such complaint, notice of violation, investigation or report pending
or, to the Company's knowledge, threatened.

         2.21      STOCKHOLDER AGREEMENTS. Except as contemplated by this
Agreement and in the SEC Reports, there are no agreements between the Company
and any of the Company's stockholders, or to the best knowledge of the Company,
among any of the Company's stockholders, which in any way affect any
stockholder's ability or right freely to alienate or vote such shares (except
restrictions designed to provide compliance with securities laws). The First
Amended and Restated Stockholders' Agreement, dated as of September 2, 1998, by
and among the Company and certain parties thereto, as amended by the Amendment
to the First Amended and Restated Stockholders' Agreement, dated as of July 21,
2000 by and among the Company and certain parties thereto, is valid, binding, in
full force and effect, and enforceable against the parties thereto.

         2.23      TITLE TO PROPERTY AND ASSETS. The Company and each of its
subsidiaries have good title to all of their material properties and assets free
and clear of all mortgages, liens and encumbrances, except liens for current
taxes and assessments not yet due and possible minor liens and encumbrances
which do not, in any case, in the aggregate, materially detract from the value
of the property subject thereto or materially impair the operations of the
Company or any of its Subsidiaries. With respect to the property and assets they
lease, the Company and each of its Subsidiaries are in compliance in all
material respects with such leases and hold a valid leasehold interest free of
all liens, claims or encumbrances. Neither the Company nor any of its
Subsidiaries owns any real property.

Purchaser true and correct copies of the Common Stock Purchase Agreements set
forth on SCHEDULE 2.24 (the "COMMON STOCK PURCHASE AGREEMENTS"), each of which
contain terms that are identical (except with respect to the name of the
Purchaser) to the terms of this Agreement. Each of the Common Stock Purchase
Agreements (together with the term sheet regarding the WorldGate Affiliation
Agreement, dated as of the date hereof, among the respective parties listed on

understandings or proposed transactions with any of its officers, directors,
affiliates or any affiliate thereof that would be required to be disclosed in
its SEC Reports.

         2.26      ABSENCE OF CHANGE. Except as set forth in the SEC Reports and
except for any changes that individually or in the aggregate could not be
reasonably expected to have a Company Material Adverse Effect, the Company's
Report on Form 10-K for the fiscal year ended December 31, 1999 remains true and
correct. To the knowledge of the Company, there is no fact, matter or event as
of the date hereof which would permit, and as of the Closing Date which will
permit, the Company to effect a Sales Blackout Period (as defined in
SECTION 7.3).

         3.6       PURCHASE WITHOUT VIEW TO DISTRIBUTE. The Purchaser

account, not as a nominee or agent, and not with a view to resale or

any notice from the Company of the occurrence of any event of the kind described
in this SECTION 7.1(c)(v)(B), (C) (but only with respect to the jurisdiction
suspending qualification), (D) or (E): (I) the Purchaser shall forthwith
discontinue any offer and disposition of the Shares pursuant to the MSO
Registration Statement covering such Shares and, if so directed by the Company,
shall deliver to the Company all copies (other than permanent file copies) of
the defective prospectus covering such Shares which are then in the Purchaser's
possession or control, and (II) the Company shall, as promptly as practicable
thereafter, take such action as shall be necessary to remedy such event to
permit the Purchaser to continue to offer and dispose of the Shares, including,
without limitation, preparing and filing with the Commission and furnishing to
the Purchaser a supplement or amendment to such prospectus so that, as
thereafter deliverable to the


                                      -14-

<PAGE>


purchasers of the Shares, such prospectus will not contain any untrue statement
of a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                        (vi)      use its best efforts to register or qualify
the Shares covered by such MSO Registration Statement under and to the extent
required by such other securities or state blue sky laws of such jurisdictions
as the Purchaser shall reasonably request, and do any and all other acts and
things which may be necessary under such securities or blue sky laws to enable
the Purchaser to consummate the public sale or other disposition in such
jurisdictions of the Shares owned by such Purchaser, except that the Company
shall not for any such purpose be required to qualify to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified or submit
to liability for state or local taxes where it would not otherwise be liable for
such taxes.

                        (vii)     notify the transfer agent of the Company's
securities that it may effect transfers of the Shares upon notification from the
Purchaser that it has complied with this Agreement and the prospectus delivery
requirements of the Securities Act.

         7.2       INFORMATION FURNISHED BY PURCHASER. It shall be a condition
precedent to the Company's obligations under this Agreement that the Purchaser
furnish to the Company in writing such information regarding the Purchaser and
the distribution proposed by the Purchaser as the Company may reasonably request
to complete or amend the information required by the MSO Registration Statement.

         7.3       INFORMATION BLACKOUT; NO STABILIZATION.

                   (a)  At any time when the MSO Registration Statement is
effective, upon written notice from the Company to the Purchaser that the
Company, after consultation with outside counsel, has determined reasonably and
in good faith that the sale of Shares pursuant to the MSO Registration Statement
would require disclosure of non-public material information, the disclosure of
which could reasonably be expected to have an adverse effect on any proposal or
plan by the Company or any of its subsidiaries to engage in any material
acquisition of assets or any merger, consolidation, tender offer or other
material transaction, the Purchaser shall suspend sales of the Shares pursuant
to the MSO Registration Statement until the earlier of (i) 45 days after the
Company notifies the Purchaser of such good faith determination, and (ii) such
time as the Company notifies the Purchaser that such material information has
been disclosed to the public or has ceased to be material or that sales pursuant
to the MSO Registration Statement may otherwise be resumed (the number of days
from such suspension of sales by the Holders until the day when such sales may
be resumed hereunder is hereinafter called a "SALES BLACKOUT PERIOD"). A Sales
Blackout Period shall not preclude any sales of Shares which the Purchaser may
effect in compliance with Rule 144; provided that the Purchaser otherwise
complies with the requirements under the Securities Act and the Exchange Act.

                   (b)  No Sales Blackout Period shall be commenced by the
Company within 120 days after the end of a Sales Blackout Period.

                   (c)  The Purchaser shall not, during the Registration Period,
(i) effect any stabilization transactions or engage in any stabilization
activity in connection with the Common Stock or other equity securities of the
Company in contravention of Regulation M under the Exchange Act, or (ii) permit
any "Affiliated Purchaser" (as that term is defined in Regulation M under the
Exchange Act) to bid for or purchase for any account in which the Purchaser has
a beneficial interest, or attempt to induce any other Person to purchase, any
shares of Common Stock or Shares in contravention of Regulation M under the
Exchange Act.

         7.4       INDEMNIFICATION.

                   (a)  With respect to the offering and sale of the Shares made
pursuant to the MSO Registration Statement only, the Company shall indemnify and
hold harmless the Purchaser, its officers, directors, members and partners, and
each Person, if any, who controls any of the foregoing persons within the
meaning of the Securities Act ("PURCHASER INDEMNITEES"), from and against any
and all claims, liabilities, losses, damages, expenses and judgments, joint or
several, to which they or any of them may become subject, including any amount
paid in settlement of any litigation commenced or threatened, and shall promptly
reimburse them, as and when incurred, for any legal or other expenses incurred
by them in connection with investigating any claims and defending any actions,
insofar as such losses, claims, damages, liabilities or actions shall arise out
of, or shall be based upon, any violation or alleged violation by the Company of
the Securities Act, any blue sky laws or securities laws of any state or country
in which the Shares are offered, and relating to action taken or action or
inaction required of the Company in connection with such offering, or shall
arise out of, or shall be based upon, any untrue statement or alleged untrue
statement of a material fact contained in the MSO Registration Statement (or in
any preliminary or final prospectus included therein) relating to the offering
and sale of the Shares, or any amendment thereof or supplement thereto, or in
any document incorporated by reference therein, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; but the Company shall not be liable to any
Purchaser Indemnitee in any such case to the extent that any such loss, claim,
damage, liability or action arises out of, or is based upon, any untrue
statement or alleged untrue statement, or any omission or alleged omission, if
such statement or omission shall have been made in reliance upon and in
conformity with information furnished to the Company in writing by or on behalf
of such Purchaser Indemnitee for inclusion in the MSO Registration Statement (or
in any preliminary or final prospectus included therein), or any amendment
thereof or supplement thereto. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnitee
and shall survive the transfer of such securities. The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have
to any Purchaser Indemnitee.

                   (b)  With respect to the offering and sale of the Shares made
pursuant to the MSO Registration Statement only, the Purchaser shall indemnify
and hold harmless the Company, its officers and directors and each person, if
any, who controls any of the foregoing within the meaning of the Securities Act
(the "COMPANY INDEMNITEES"), from and against any and all claims, liabilities,
losses, damages, expenses and judgments, joint or several, to which they or any
of them may become subject, including any amount paid in settlement of any
litigation commenced or threatened, and shall promptly reimburse them, as and
when incurred, for any legal or other expenses incurred by them in connection
with investigating any claims and defending any actions,


                                      -16-

<PAGE>


insofar as any such losses, claims, damages, liabilities or actions shall arise
out of, or shall be based upon, any violation or alleged violation by the
Purchaser of the Securities Act, any blue sky laws or securities laws of any
state or country in which the Shares are offered and relating to action taken or
action or inaction required of the Purchaser in connection with such offering,
or shall arise out of, or shall be based upon, any untrue statement or alleged
untrue statement of a material fact contained in the MSO Registration Statement
(or in any preliminary or final prospectus included therein) relating to the
offering and sale of the Shares or any amendment thereof or supplement thereto,
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, but in each case only
to the extent that such untrue statement is contained in, or such fact is
omitted from, information furnished to the Company in writing by or on behalf of
the Purchaser for inclusion in the MSO Registration Statement (or in any
preliminary or final prospectus included therein). Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
any Company Indemnitee. The foregoing indemnity is in addition to any liability
which the Purchaser may otherwise have to any Company Indemnitee.

                   (c)  In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to this SECTION 7.4, such person (the
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing. No
indemnification provided for in subsection (a) or (b) shall be available to any
person who shall fail to give notice as provided in this subsection (c) if the
indemnifying party to whom notice was not given was unaware of the proceeding to
which such notice would have related and was materially prejudiced by the
failure to give such notice, but the failure to give such notice shall not
relieve the indemnifying party or parties from any liability which it or they
may have to the indemnified party for indemnification pursuant to subsection (a)
or (b) to the extent it was not materially prejudiced or for contribution or
otherwise than on account of the provisions of subsection (a) or (b). In case
any such proceeding shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party and shall pay as incurred the fees and disbursements of such counsel
related to such proceeding. In any such proceeding, any indemnified party shall
have the right to retain its own counsel at its own expense. Notwithstanding the
foregoing, the indemnifying party shall pay as incurred the fees and expenses of
the counsel retained by the indemnified party in the event (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of
such counsel, (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
and representation of both parties by the same counsel, in the written opinion
of such counsel, would be inappropriate due to actual or potential differing
interests between them, or (iii) the indemnifying party does not promptly defend
the indemnified party. The indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
reasonable fees and expenses of more than one separate firm for all such
indemnified parties (in addition to local counsel). Such firm shall be
designated in writing by the Purchaser in the case of Purchaser Indemnitees and
by the Company in the case of Company Indemnitees. The indemnifying party shall
not be liable for any settlement of any proceeding effected without its written
consent (which shall not be unreasonably withheld) but if settled with such
consent or if


                                      -17-

<PAGE>


there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment.

                   (d)  The indemnity provided for hereunder shall not inure to
the benefit of any indemnified party to the extent that the claim is based on
such indemnified party's failure to comply with the applicable prospectus
delivery requirements of the Securities Act as then applicable to the person
asserting the loss, claim, damage or liability for which indemnity is sought.

                   (e)  In no event shall the liability of the Purchaser under
this Section 7.4 exceed the proceeds received by the Purchaser from the sale of
Shares pursuant to the MSO Registration Statement.

                   (f)  The provisions of this SECTION 7.4 shall be separate and
distinct from the provisions of ARTICLE 10 and shall not be subject to the
limitations on indemnification obligations set forth therein.

         7.5       RULE 144. With a view to making available to the Purchaser
the benefits of Rule 144 and any other rule or regulation of the Commission that
may at any time permit the Purchaser to sell securities of the Company to the
public without registration, the Company shall:

                   (a)  make and keep adequate current public information with
respect to the Company available, as those terms are understood and defined in
Rule 144;

                   (b)  use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

                   (c)  furnish to the Purchaser upon written request (i) a
written statement by the Company as to whether it has complied with the
reporting requirements of Rule 144, the Securities Act and the Exchange Act,
(ii) a copy of the most recent annual or quarterly report of the Company, and
(iii) such other reports and documents of the Company as the Purchaser may
reasonably request and as is publicly available to enable the Purchaser to avail
itself of any rule or regulation of the Commission which permits the selling of
any such securities without registration.

                                   ARTICLE 8
                         COMPLIANCE WITH SECURITIES ACT;
                    RESTRICTIONS ON TRANSFERABILITY OF SHARES

         8.1       COMPLIANCE WITH SECURITIES ACT. The Shares shall not be
transferable, except to Affiliates and except upon the conditions specified in
SECTION 8.3, which conditions are intended among other things to insure
compliance with the provisions of the Securities Act and applicable state
securities laws in respect of any such transfer.

         8.2       RESTRICTIVE LEGEND. Each certificate representing the Shares
shall (unless otherwise permitted by the provisions of SECTION 8.4 below) be
stamped or otherwise imprinted with the legend in substantially the form as
follows:


                                      -18-

<PAGE>


         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
         SECURITIES LAW."

         8.3       RESTRICTIONS ON TRANSFERABILITY. The Company shall not be
required to register the transfer of the Shares on the books of the Company
unless the Company shall have been provided with an opinion of counsel
reasonably satisfactory to it prior to such transfer to the effect that
registration under the Securities Act or any applicable state securities law is
not required in connection with the transaction resulting in such transfer;
PROVIDED, HOWEVER, that no such opinion of counsel shall be necessary in order
to effectuate a transfer of Shares in accordance with the provisions of Rule
144(k) promulgated under the Securities Act or in accordance with the MSO
Registration Statement. Each certificate for Shares issued upon any transfer as
above provided (except for transfers in accordance with the MSO Registration
Statement) shall bear the restrictive legend set forth in SECTION 8.2 above,
except that such restrictive legend shall not be required if the opinion of
counsel reasonably satisfactory to the Company referred to above is to the
further effect that such legend is not required in order to establish compliance
with the provisions of the Securities Act and any applicable state securities
law, or if the transfer is made in accordance with the provisions of Rule 144(k)
under the Securities Act.

         8.4       TERMINATION OF RESTRICTIONS ON TRANSFERABILITY. The
conditions precedent imposed by this ARTICLE 8 upon the transferability of the
Shares shall cease and terminate as to any of the Shares when (a) such
securities shall have been registered under the Securities Act and sold or
otherwise disposed of in accordance with the intended method of disposition by
the seller or sellers thereof set forth in the registration statement covering
such securities, (b) at such time as an opinion of counsel satisfactory to the
Company shall have been rendered as required pursuant to the second sentence of
SECTION 8.3 to the effect that the restrictive legend on such securities is no
longer required, or (c) when such securities are transferred pursuant to Rule
144 or become transferable in accordance with the provisions of Rule 144(k)
promulgated under the Securities Act. Whenever the conditions imposed by this
ARTICLE 8 shall terminate as hereinabove provided with respect to any of the
Shares, the holder of any such securities bearing the legend set forth in this
ARTICLE 8 as to which such conditions shall have terminated shall be entitled to
receive from the Company, without expense (except for the payment of any
applicable transfer tax) and as expeditiously as possible, new stock
certificates not bearing such legend.

                                   ARTICLE 9
                       SURVIVAL OF COVENANTS, AGREEMENTS,
                         REPRESENTATIONS AND WARRANTIES

         All covenants, agreements, representations and warranties made herein
shall survive the Closing to the extent provided in ARTICLE 10(d) and shall not
merge in the performance of any obligation by any party hereto; PROVIDED,
HOWEVER, that representations and warranties made herein shall only be deemed to
have been made as of the date hereof and as of the Closing Date (or as of such
other date referenced in such representation or warranty).

                                   ARTICLE 10
                                 INDEMNIFICATION

                   (a)  Effective at the Closing, the Company shall indemnify,
hold harmless and defend the Purchaser and its Affiliates, against and in
respect of any and all claims, demands, liabilities, losses, costs and expenses
(including reasonable attorneys' fees and litigation expenses) arising out of or
based upon (i) the breach of any representation or warranty made by the Company
in this Agreement or in any certificate or other document required to be
delivered pursuant hereto, or (ii) the breach by the Company of any agreement or
covenant contained in this Agreement.

                   (b)  Effective at the Closing, the Purchaser shall indemnify,
hold harmless and defend the Company and its Affiliates against and in respect
of any and all claims, demands, liabilities, losses, costs and expenses
(including reasonable attorneys' fees and litigation expenses) arising out of or
based upon (i) the breach of any representation or warranty made by the
Purchaser in this Agreement or in any certificate or other document required to
be delivered pursuant hereto, or (ii) the breach by the Purchaser of any
agreement or covenant contained in this Agreement.

                   (c)  No party shall be liable for indemnification under this
ARTICLE 10 unless the total of all liabilities, costs, losses and expenses for
which the Indemnified Party (as defined below) has a right to indemnification
under this ARTICLE 10 (collectively, the "INDEMNIFIABLE DAMAGES") exceeds
$500,000 (the "THRESHOLD AMOUNT"), in which event the Indemnified Party shall be
entitled to all Indemnifiable Damages, including the Threshold Amount.

                   (d)  No claims for indemnification under this ARTICLE 10 may
be made later than the first anniversary of the Closing, with respect to the
inaccuracy or breach of a representation or warranty, or two (2) years after
such breach first occurred with respect to the breach of a covenant or
agreement; provided, however, that the indemnification provisions set forth in
SECTION 7.4 shall survive until the expiration of the applicable statute of
limitations. No provision of this Agreement shall limit the ability of either
party to obtain specific performance of the other party's obligations hereunder.

                   (e)  The party seeking indemnification under this ARTICLE 10
(the "INDEMNIFIED PARTY") shall give prompt notice to the party against whom
indemnity is sought (the "INDEMNIFYING PARTY") of the assertion of any claim, or
the commencement of any suit, action or proceeding, in respect of which
indemnity may be sought under this ARTICLE 10. The Indemnifying Party may
participate in, and, at its election, control the defense of any such suit,
action or proceeding at its own expense; PROVIDED that counsel selected to
conduct such defense is reasonably satisfactory to the Indemnified Party. The
Indemnifying Party shall not be liable under this ARTICLE 10 in the event prompt
notice of the assertion of a claim or the commencement of a suit, action or
proceeding in respect of which indemnity is sought is not given as described
herein, but only to the extent the defense of such claim, suit, action or
proceeding is materially prejudiced thereby, or for any settlement effected
without its consent of any claim, litigation or proceeding in respect of which
indemnity may be sought hereunder. The Indemnifying Party may settle or
compromise any claim without the prior written consent of the Indemnified Party;
PROVIDED that the Indemnifying Party may not agree, without the prior written
consent of the


                                      -20-

<PAGE>


Indemnified Party, to any such settlement pursuant to which any remedy or relief
(including, without limitation, any injunctive relief or other remedy) would be
imposed on or against the Indemnified Party which is not covered by the
indemnity obligations hereunder and promptly paid by the Indemnifying Party; and
further provided that such settlement or compromise shall release the
Indemnified Party of all liabilities.

                                   ARTICLE 11
                                   TERMINATION

         11.1      TERMINATION. This Agreement may be terminated at any time:

                   (a)  by mutual consent of the Company and the Purchaser in a
written instrument;

                   (b)  by either the Purchaser or the Company if there has been
a material breach on the part of the other of any representation, warranty,
covenant or agreement set forth in this Agreement, which breach has not been
cured within thirty (30) business days following receipt by the breaching party
of notice of such breach; or

                   (c)  by either the Company or the Purchaser if the Closing
shall not have occurred on or before 90 days after the date hereof unless the
failure to close by such time is due to the breach of this Agreement by the
party seeking to terminate; provided that the if the MSO Registration Statement
has not been declared effective within such 90-day period, the Purchaser, in its
sole discretion, may extend such 90-day period for an additional 60 days.

         11.2      EFFECT OF TERMINATION. In the event of termination of this
Agreement by either the Company or the Purchaser as provided in SECTION 11.1,
this Agreement shall forthwith become void; PROVIDED, HOWEVER, that no
termination of this Agreement shall relieve any party from liability resulting
from a prior breach by such party of any of its representations, warranties,
covenants or agreements set forth herein.

                                   ARTICLE 12
                                  MISCELLANEOUS

         12.1      PUBLICITY. Except as otherwise required by law or regulation
or for such information already publicly known, none of the parties hereto shall
issue any press release or make any other public statement, in each case
relating to or connected with or arising out of this Agreement or the matters
contained herein, without obtaining prior written approval of the Purchaser and
the Company to the contents and the manner of presentation and publication
thereof and the parties shall cooperate and seek the other party's comment with
respect to any disclosures required by law.

         12.2      SPECIFIC ENFORCEMENT; VENUE. The parties hereto acknowledge
and agree that each would be irreparably damaged if any of the provisions of
this Agreement are not performed by the other in accordance with their specific
terms or are otherwise breached. It is accordingly agreed that each party shall
be entitled to seek an injunction or injunctions to prevent breaches of this
Agreement by the other and to enforce this Agreement and the terms and
provisions thereof specifically against the other, in addition to any other
remedy to which such aggrieved party may be entitled at law or in equity. Any
action or proceeding seeking to enforce any provision of, or


                                      -21-

<PAGE>


based on any right arising out of, this Agreement may be brought against any of
the parties in the courts of the Commonwealth of Pennsylvania, County of
Philadelphia, or in the United States District Court for the Eastern District of
Pennsylvania, and each of the parties consents to the jurisdiction of such
courts (and of the appropriate appellate courts) in any such action or
proceeding and waives any objection to venue laid therein. Process in any action
or proceeding referred to in the preceding sentence may be served on any party
anywhere in the world.

         12.3      SEVERABILITY. If any term or provision of this Agreement is
held by a court of competent jurisdiction or other authority to be invalid,
void, unenforceable or against its regulatory policy, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

         12.4      EXPENSES. Except as otherwise provided herein, each party
hereto shall pay its own expenses in connection with this Agreement.

         12.5      ASSIGNMENT; SUCCESSORS. This Agreement shall be binding upon
and shall inure to the benefit of and be enforceable by the successors and
permitted assigns of the parties hereto. The Company may not assign its rights
and delegate its duties and obligations under this Agreement without the prior
written consent of the Purchaser (which consent shall not be unreasonably
withheld or delayed), and the Purchaser may not assign its rights or delegate
its duties and obligations under this Agreement without the prior written
consent of the Company (which consent shall not be unreasonably withheld or
delayed) and, in the absence of such consent, any such purported assignment or
delegation shall be void. Notwithstanding the provisions of the immediately
preceding sentence, the Purchaser may assign all or any portion of its rights,
interest and obligations under this Agreement to one or more Affiliates of the
Purchaser, without the prior written consent of the Company, provided that the
Purchaser shall not be released from its obligations hereunder and provided the
Purchaser shall give the Company prior written notice of such assignment.

         12.6      AMENDMENTS. This Agreement may not be modified, amended,
altered or supplemented except by a written agreement signed by the Company and
