                    Notes to Unaudited Financial Statements
                    Six Months Ended June 30, 1998 and 1997

(1)  Basis of Presentation
     ---------------------

     The accompanying unaudited financial statements of Physicians Quality Care,
Inc., a Delaware corporation (the "Company"), have been prepared in accordance
with generally accepted accounting principles and in accordance with Rule 10-01
of Regulation S-X.

     In the opinion of management, the unaudited interim financial statements
contained in this report reflect all adjustments, consisting of only normal
recurring accruals which are necessary for a fair presentation of the financial
position as of June 30, 1998 and the results of operations for the three and six
months ended June 30, 1998. The results of operations for the three and six
month periods ended June 30, 1998 are not necessarily indicative of results for
the full year.

     These unaudited financial statements, footnote disclosures and other
information should be read in conjunction with the financial statements and
notes thereto included in the Company's Registration Statement on Form S-1, as
amended (No. 333-26137), and the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1997.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the accompanying financial
statements and notes.  Actual results could differ from those estimates.

(2)  Net Loss Per Common Share
     -------------------------

     Net loss per share of common stock is computed by dividing the net loss
available to common stock by the weighted-average number of shares of common and
common equivalent shares outstanding during each period presented. The net loss
available to common stock for the three and six months ended June 30, 1998 and
June 30, 1997 reflect the accretion of common stock subject to put to fair value
at those respective balance sheet dates. The effect of options and warrants is
not considered as it would be antidilutive. Fully diluted loss per share is not
presented because the effect would be antidilutive.

     In February 1997, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 128 "Earnings
Per Share", which established standards for computing and presenting earnings
per share ("EPS") and applies to entities with publicly held common stock or
potential common stock.  SFAS 128 is effective for financial statements issued
for both interim and annual periods ending after December 31, 1997 and requires
restatement of all prior period EPS data.  Under the new requirements for
calculating primary 

                                       4
<PAGE>

 
earnings per share, the dilutive effect of stock options will be excluded. The
Company has applied this standard in 1997 and 1998.

(3)  Pending Accounting Standards
     ----------------------------
 
     In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive
Income," and SFAS No. 131 "Disclosures About Segments of an Enterprise and
Related Information."  SFAS No. 130 establishes standards for reporting and
displaying comprehensive income and its components.  SFAS No. 131 establishes
standards for public companies to report information about operating segments in
financial statements and supersedes SFAS No. 14 "Financial Reporting for
Segments of a Business Enterprise," but retains the requirements to report
information about major customers.  SFAS No. 130 and SFAS No. 131 are effective
for the Company in 1998.  The Company does not believe the adoption of these
Statements will have a significant effect on its financial statements.     

     In November 1997, the Financial Accounting Standards Board's Emerging 
Issues Task Force reached a consensus on its Issue 97-2, Consolidation of 
Physician Practice Entities which is effective for the Company for its 1998 
annual financial statements. The Company is currently evaluating the guidance 
contained in the consensus as it affects its current model for its affiliation 
structures. However, management does not believe implementation of the consensus
guidance will materially affect the financial position or its net results of 
operations.

(4)  Contingency
     -----------

     On June 12, 1997, Jay N. Greenberg, a founder and former executive vice
president of the Company, filed a complaint against the Company in Massachusetts
state court seeking damages of $1.4 million and a declaratory judgment that
843,750 of the shares registered in Mr. Greenberg's name (out of 1,012,500
shares of Class A Common Stock originally granted to Mr. Greenberg) have
"vested" under his Employment Agreement. The Company and Mr. Greenberg entered
into a Settlement Agreement in April 1998 pursuant to which the Company
confirmed Mr. Greenberg's ownership of 1,012,500 shares of Class A Common Stock
and Mr. Greenberg granted the Company an option to purchase all of such shares.
The purchase price is $1.3 million and increases (commencing October 1997) by
$25,000 for each three month period thereafter. The Company's purchase option 
expires on the earlier of (i) October 14, 1999, (ii) upon a public offering of
the capital stock of the Company, or (iii) a change in control. No damages were
awarded and mutual releases were granted.

(5)  LETTER OF CREDIT
     ----------------
     In connection with the October 1997 acquisition of a 50% interest in TLC 
Management Company, a medical management company ("TLC"), and a 50% interest in 
Total Quality Practice Management, Inc., a practice management company providing
Medicare risk management services ("Total Quality"), the Company issued a $1.0 
million letter of credit in April 1998. In connection with this letter of 
credit, the Company is required to maintain a cash balance of $1 million which 
is included under the caption "restricted cash" on the balance sheet.

(6)  Subsequent Event
     -----------------
     On July 15, 1998, the Company issued  2,461,538  shares of Class L Common
Stock to certain  institutional investors pursuant to a Class L Common Stock
Purchase Agreement.  The purchase price was $3.25 for each share of Class L
Common Stock for an aggregate purchase price of approximately $8,000,000. In
connection with such transaction the rights of the Class B Common Stock in a
liquidation were amended to rank prior to the Class A Common Stock and on an
equal basis with the Class C Common Stock.  The exercise price of the
outstanding Class B and Class C Common Stock warrants were reduced by $2.00 per
share to $0.50 and $1.25 per share respectively.  No distribution, whether as a
dividend, upon liquidation or otherwise, may be made on any other class of
Common Stock until the holders of the Class L Common Stock have received
dividends or distributions equal to the purchase price of the Class L Common
Stock plus an additional 12% per annum. In connection with the Class L Common
Stock financing, the Company's Shareholders approved a Restated Certificate of
Incorporation. The Restated Certificate limits any distribution on capital stock
that constitutes a taxable distribution.


                             
<PAGE>
 
     The Class L Common Stock automatically converts into Class A Common Stock
upon the occurrence of a public offering that satisfy certain criteria, upon a
merger, consolidation, liquidation or winding up of the Company or a sale or
other transfer of all or substantially all of the Company's assets, or certain
other conditions brought about by partial redemption of Class L Common Stock.
The Class L Common Stock is also convertible at any time at the option of the
holder.

     The number of shares of Class A Common Stock into which the Class L
Common Stock is convertible is determined according to a formula and is based on
the value of Class A Common Stock issued pursuant to a realization event. The 
number of shares of Class A Common Stock issuable upon conversion (assuming no 
accrued and unpaid dividends) ranges between 4,923,007 and 12,603,077.

     The proceeds of the sale of Class L Common Stock will be used for working
capital and other corporate purposes.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS.

     This Quarterly Report on Form 10-Q contains forward-looking statements that
involve a number of risks and uncertainties.  There are a number of important
factors that could cause the Company's actual results to differ materially from
those indicated by such forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed under
"Factors Affecting Future Operating Results."  The following discussion should
be read in conjunction with the Company's Unaudited Financial Statements and
Notes thereto included elsewhere in this documents.

OVERVIEW

     The Company is affiliated with and operates multi-specialty medical
practice groups.  The first physician affiliation was completed on August 30,
1996 with 32 physicians in the Springfield, Massachusetts area (the "Springfield
Affiliated Group").  On December 11, 1996 the Company consummated the
affiliation with Flagship Health, P.A., a Maryland professional association
("Flagship," and together with Flagship II, the "Flagship Affiliated Group"),
which consisted of 59 physicians in the Baltimore, Maryland area.  On December
1, 1997, the Company entered into a long term affiliation agreement with a
physician practice consisting of 58 physicians in the Baltimore, Maryland area.
Additional physicians have been subsequently added to the Springfield Affiliated
Group and the Flagship Affiliated Group (the "Affiliated Groups") during 1997
and 1998.  In connection with the affiliation transactions, the assets and
liabilities of the physician practices were transferred to newly formed
professional corporations ("PCs") or professional associations ("PAs")
affiliated with the Company.  The Company is working with these groups of
physicians to improve operating practices and to obtain managed care contracts.
On October 24, 1997, the Company acquired a 50% interest in Total Life 
Care, a medical management company based in Atlanta, Georgia.

     As of June 30, 1998, the Company had affiliations or independent provider
association ("IPA") arrangements with the following physicians:

     Under the Company's contractual arrangements with its Affiliated Groups,
the Company can improve its management fee revenues by increasing the patient
care revenue of its Affiliated Groups, through improved billing and operating
efficiency, additional patient encounters, increased capitated revenues and
controlling the expenses of Affiliated Groups. To the extent that patient
revenue increases at a greater rate than practice expenses, the Company's
management fee will increase. Conversely, if PQC is not able to control practice
expenses or assist the Affiliated Groups in increasing patient care revenue, the
Company will earn no or only a limited management fee. Under the arrangements
with the physicians formally associated with Clinical Associates, P.A. (which
became effective on December 1, 1997) the Company earns a fee based, in part,
upon increases in billings, net of bad debts and discounts, above historical
levels, and a reduction in the percentage of revenue needed to pay practice
expense. While this structure causes the Company's management fee not to be as
dependent upon controlling practice expenses, the Company believes that both
increased revenues depend upon affiliated physicians being motivated by
competitive levels of compensation.

     The Company's and its Affiliated Groups revenues are derived from
governmental programs, managed care payors and traditional fee-for service
arrangements.  The following table sets forth the approximate percentage of the
revenues received by the practices that were affiliated with the Company at and
during the three month period ended June 30, 1998:

RESULTS OF OPERATIONS:

Three Months ended June 30, 1998 and June 30, 1997

     Net patient revenues of affiliated practices were $20.6 million for the
three months ended June 30, 1998 compared to $10.7 million for the same period a
year ago.  The increase of  $9.9 million in net revenues was primarily due to
the Flagship II affiliation in December, 1997. Capitated managed care contracts
were 27% of revenues for the three months ended June 30, 1998 compared to 9% for
the three months ended June 30, 1997.  Capitated contracts have increased as a
source of revenue in 1998 due to the Flagship II affiliation.

                                       8

     Amounts retained by physician groups, which represents physician salaries
and benefits, increased  $1.6 million for the three months ended June 30, 1998
compared to the three months ended June 30, 1997.  This is primarily due to the
increase in affiliated physicians from 1997 to 1998.  As a percentage of net
patient service revenues, amounts retained by physician groups was 26% for the
three months ended June 30, 1998 compared to 35% for the three months ended June
30, 1997.  This was primarily due to the Flagship II affiliation which has a
lower physician compensation ratio to net revenues than the prior affiliations.

     Nonphysician salaries and benefits, which represents salaries and benefits
for physician practice staff increased by $3.7 million to $6.8 million for the
three months ended June 30, 1998 from $3.1 for the three months ended June 30,
1997. As a percentage of net patient service revenues, Nonphysician salaries and
benefits was 33% for the three months ended June 30, 1998 compared to 29% for
the three months ended June 30, 1997. Other practice expenses, which represent
all other physician practice expenses, increased $4.3 million and as a
percentage of net revenue to 35% for the three months ended June 30, 1998
compared to 27% for the three months ended June 30, 1997. The increase in
Nonphysician salaries and benefits and other practice expenses is primarily a
result of the Flagship II affiliation which has higher infrastructure expenses.
The infrastructure expenses include outside services and administrative costs
associated with capitated managed care contracts.

     Corporate and regional expenses increased $827,000 for the three months
ended June 30, 1998 compared to the three months ended June 30, 1997. This
increase was due to the hiring of corporate and regional staff and related
expenses to support the affiliated practices. Corporate and regional expenses
were 10% of revenues for the three months ended June 30, 1998 compared to 12%
for the three months ended June 30, 1997.

     Depreciation and amortization expense was $843,000 for the three months
ended June 30, 1998 compared to $617,000 for the three months ended June 30,
1997. The increase was due to the Flagship II affiliation completed in December
1997 and is primarily related to the amortization of intangible assets from the
affiliation transactions.

     Provisions for bad debt expense increased by $496,000 for the three months
ended June 30, 1998 compared to the three months ended June 30, 1997 and
increased as a percentage of net revenue to 4% from 3% for the same periods. The
increases in provisions for bad debts is due to the provisions for Flagship II
affiliation and patient mix compared to prior affiliations.

     Interest income increased for the three months ended June 30, 1998 compared
to the three months ended June 30, 1997 due to a higher level of invested cash
over the entire period.

<PAGE>
 
     Loss in investment for the three months ended June 30, 1998 was $190,000.
The Company acquired a 50% interest in Total Life Care on October 24, 1997 and
has accounted for the transaction using the equity method.

 Six Months ended June 30, 1998 and June 30, 1997

     Net patient revenues of affiliated practices for the six months ended June
30, 1998 were $41.8 million compared to $21.2 million for the same period a year
ago. The increase of $20.6 million in net revenues was primarily due to the
Flagship II affiliation. Capitated managed care contracts were 27% of revenues
for the six months ended June 30, 1998 compared to 9% for the six months ended
June 30, 1997. Capitated contracts have increased as a source of revenue in 1998
due to the Flagship II affiliation.

     Amounts retained by physician groups, which represents physician salaries
and benefits, increased $4.5 million for the six months ended June 30, 1998
compared to the six months ended June 30, 1997. This is primarily due to the
increase in affiliated physicians from 1997 to 1998. As a percentage of net
patient service revenues, amounts retained by physician groups was 29% for the
six months ended June 30, 1998 compared to 35% for the six months ended June 30,
1997. This was primarily due to the Flagship II affiliation which has a lower
physician compensation ratio to net revenues than the prior affiliations.

     Nonphysician salaries and benefits, which represent salaries and benefits
for physician practice staff increased by $7.4 million to $13.6 million for the
six months ended June 30, 1998 from $6.2 million for the six months ended June
30, 1997. As a percentage of net patient service revenues, Nonphysician salaries
and benefits was 33% for the six months ended June 30, 1998 compared to 29% for
the six months ended June 30, 1997. Other practice expenses, which represent all
other physician practice expenses, increased $7.7 million and as a percentage of
net revenue to 32% for the six months ended June 30, 1998 compared to 27% for
the six months ended June 30, 1997. The increase in Nonphysician salaries and
benefits and other practice expenses is primarily a result of the Flagship II
affiliation which has higher infrastructure expenses. The infrastructure
expenses include outside services and administrative costs associated with
capitated managed care contracts.

     Corporate and regional expenses increased $1.5 million for the six months
ended June 30, 1998 compared to the six months ended June 30, 1997. This
increase was due to the hiring of corporate and regional staff and related
expenses to support the affiliated practices. Corporate and regional expenses
were 10% of revenues for the six months ended June 30, 1998 compared to 13% for
the six months ended June 30, 1997.

     Depreciation and amortization expense was $1.5 million for the six months
ended June 30, 1998 compared to $958,000 for the six months ended June 30, 1997.
The increase was due to the Flagship II affiliation completed in December 1997
and is primarily related to the amortization of intangible assets from the
affiliation transactions.

                                       10

     Provisions for bad debts increased by $911,000 for the six months ended
June 30, 1998 compared to the six months ended June 30, 1997 and increased as a
percentage of net revenue to 3.5% from 2.6% for the same periods. The increases
in provisions for bad debts is due to the Flagship II affiliation and patient
mix compared to prior affiliations.

     Interest income increased for the six months ended June 30, 1998 compared
to the six months ended June 30, 1997 due to a higher level of invested cash
over the entire period.

     Loss in investment for the six months ended June 30, 1998 was $323,000. The
Company acquired a 50% interest in Total Life Care on October 24, 1997 and has 
accounted for the transaction using the equity method.

 LIQUIDITY AND CAPITAL RESOURCES:

     Principal capital requirements include payments for affiliation
transactions, related transaction costs, working capital requirements, and the
funding of operating losses.  The Company anticipates that its liquidity and
capital requirements will be the same for the short-term and long-term.  The
Company has incurred significant operating losses to date and does not have
operating cash flow to fund further losses.  The principal sources of capital
have been the issuance of Class B, Class C, and Class L Common Stock to
institutional investors, and the issuance of Class A Common Stock to private
investors.  Capital expenditures are expected to be $2 million for 1998.  There
can be no assurance that the institutional investors, who have previously been a
source of capital, will continue to fund the operations through the purchase of
additional equity.

     Working capital existing at the date of the affiliation transactions has
been retained in the affiliated groups.  Additional working capital is required
to fund growth and manage accounts receivable fluctuations.  The affiliated
groups had net accounts receivable of $14.4 million at June 30, 1998 compared to
$11.9 million at December 31, 1997.  The $2.5 million increase in accounts
receivable is due to billing delays caused by system conversions.  Management
believes that the increases are temporary and anticipates that the system
conversions will be completed by December 31, 1998.

     During 1998 and 1997 the Company paid an aggregate consideration of $1.5
and $23.6 million, respectively, in connection with affiliation transactions. Of
that amount $50,000 in 1998 and $7.8 million in 1997 was paid in cash and $1.5
million in 1998 and $15.8 million in 1997 was paid in Class A Common Stock. The
majority of the consideration has been ascribed to intangible assets.

     As of June 30, 1998, intangible assets net of amortization costs,
represented  $54 million of the total assets of  $70 million.  The Company is
amortizing the intangible assets over 25 years.

     Continuing operating losses, working capital requirements and other
expenditures caused the company to experience a net reduction in cash and cash
equivalents of $9 million during the six 

                                       11
<PAGE>
 
months ended June 30, 1998. As a result of such reduction in working capital,
the Company had a negative balance of unrestricted cash of ($258,000) at June
30, 1998 and its current assets at such date were principally composed of
amounts due from affiliated physician practices. Delays in billings and
collections at the affiliated practices due principally to systems conversions
contributed to the decrease in cash and the increase in amounts due from
affiliates. While the Company is addressing the billing and collection problems
at the affiliated practice, the Company faced a serious shortfall in working
capital. To address this problem and to fund its operations and growth, the
Company issued 2,461,538 shares of Class L Common Stock to certain institutional
investors pursuant to a Class L Common Stock Purchase Agreement. The purchase
price was $3.25 for each share of Class L Common Stock for an aggregate purchase
price of approximately $8 million. In connection with such transaction the
rights of the Class B Common Stock in a liquidation were amended to rank prior
to the Class A Common Stock and on an equal basis with the Class C Common Stock.
The exercise price of the outstanding Class B and Class C Common Stock warrants
were reduced by $2.00 per share to $0.50 and $1.25 per share respectively. While
the Company believes that the proceeds from the Class L Common Stock financing
will be sufficient to fund the Company's operations for the current year, the
Company will continue periodically to experience shortfalls in working capital
unless it is able to generate a positive cash follow from its operations. There
can be no assurance that additional equity financing will be available in the
future from the institutional investors in the Company or other sources.
 
     Of the common stock outstanding at June 30, 1998, 18,604,136 shares of
Class A Common are subject to a put option which provided for the purchase of
the shares at fair value upon the death of the holder.  In addition, 1,029,749
shares are subject to a fair value put option back to the Company at the later
of the physician shareholder's retirement or June 1998.  These Class A Common
Shares have been recorded at fair value on the accompanying balance sheet. Under
the stockholder agreements as of December 31, 1997, the Company has the right to
repurchase 15,471,063 shares of Class A Common Stock for fair value if the
physician shareholder's termination of employment is without cause or is by
resignation, and for the lower of cost or fair value if termination is with
cause.  The terms of such repurchase provisions may not permit the Company to
fully recover its physician affiliation payments or reflect the cost of
affiliation transactions at the time of termination.  To date, no physician
shareholder has terminated an employment agreement or repurchased any practice
assets.  All of the put and call provisions expire on the completion of an
initial public offering with net proceeds of $50 million and which meets certain
other criteria.  In addition, the Flagship II physicians have the right to
require the Company to repurchase through a five year non-interest bearing note
4.8 million shares of Class A Common Stock at $3.00 per share if the Company has
not completed an  initial public offering prior to December 1, 2001.  The Class
A Common Stock is subject to a number of restrictions in the stockholder
agreements and will not trade until the occurrence of an offering.  The Company
has not recorded a compensation expense for these puts and calls and believes it
is a nonpublic entity for compensation accounting purposes.

IMPACT OF YEAR 2000

     The Company is aware of issues associated with the programming code in
existing computer systems as the year 2000 approaches.  The "Year 2000" problem
is pervasive and complex, as virtually every computer operation will be affected
in the same way by the rollover of the two digit year value to 00.  The issue is
whether computer systems will properly recognize date sensitive information when
the year changes to 2000.  Systems that do not properly recognize such
information could generate erroneous data or cause a system to fall.

     The Company is utilizing both internal and external resources to identify,
correct or reprogram, and test its systems for Year 2000 compliance.  It is
currently anticipated that all reprogramming efforts will be completed by July
31, 1999, allowing adequate time for testing. A preliminary assessment has
indicted that some of the Company's older personal computers and ancillary
software programs may not be Year 2000 compatible.  The Company intends to
either replace or modify these computers and programs.  The cost of this
replacement in not expected to be material as the shelf life of the Company's
personal computers is three to five years.  The present financial systems are
all Year 2000 compliant.  The practice management system is 80% compliant and
the Company plans to move to a new version of the software which is 100%
compliant as part of its reprogramming efforts which will be completed by July
31, 1999.  This upgrade is provided under the Company's current software
maintenance agreement with its software vendor.  All new software purchased will
be 100% compliant.

     The Company is also obtaining confirmations from the Company's primary
vendors that plans are already in place to address processing of transactions in
the Year 2000.  However, there can be no assurance that the systems of other
companies on which the Company's systems rely also will be converted in a timely
fashion or that any such failure to convert by another company would not have an
adverse effect on the Company's systems.  Management is in the process of
completing the assessment of the Year 2000 compliance costs.  However, based on
currently available information (excluding the possible impact of vendor systems
which management currently is not in a position to evaluate) as noted above,
management does not believe that these costs will have a material effect on the
Company's earnings.

FACTORS AFFECTING FUTURE OPERATING RESULTS

     Lack of Operating History; History of Operating Losses

     The Company's historical financial condition and results of operations may
not be indicative of the Company's results of operations and financial condition
for future periods.  The Company has incurred losses of each of its fiscal years
through 1997.  The Company expects to incur operating losses for at least the
immediate future and to fund such operating losses through the issuance of
additional equity and debt securities.  See "-- Need for Substantial Additional
Capital."  There can be no assurance that the Company will achieve or maintain
profitability.

                                       13
<PAGE>
 
     Need for Substantial Additional Capital

     The Company will require substantial capital resources to obtain the
necessary scale to become profitable and to fulfill its business plan.
Additional funds will be required to fund the acquisition, integration,
operation and expansion of affiliated practices, capital expenditures including
the development of the information systems to manage such practices, operating
losses and general corporate purposes.

     The Company has no committed external sources of capital.  Without the
consent of the director elected by the stockholders of the Class B-1 Common
Stock (the "Class B-1 Director"), the director elected by the stockholders of
the Class B-2 Common Stock (the "Class B-2 Director," and together with the
Class B-1 Director of the "Class B Directors") and the directors elected by the
holders of Class C Common Stock (the "Class C Directors"), the Company may not
obtain additional financing through external borrowings or the issuance of
additional securities.  The issuance of additional capital stock could have an
adverse effect on the value of the shares of common stock held by the existing
stockholders.  There can be no assurance that the Class B Directors and Class C
Directors will approve such capital raising activities or that the Company will
be able to raise additional capital when needed on satisfactory terms or at all.
In July 1998, the Company issued 2,461,538 shares of Class L Common Stock for an
aggregate consideration of $8 million to finance the Company's working capital
shortfall and its ongoing operations.  Because of the Company's working capital
requirements and operating losses, as well as a general change in the market
valuation of physician management companies, the terms of the Class L Common
Stock financing were less favorable to the Company than its prior institutional
offerings. If the Company is not able to eliminate its operating losses, the
Company will need additional working capital in the future.  Additional capital
may also be needed to finance the expansion of the Company's operations.  The
Company may not be able to obtain such additional financing when needed or may
not be able to do so on favorable terms.  The failure to obtain additional
financing when needed and on appropriate terms could have a material adverse
effect on the Company.

     Risk that Future Affiliation Transactions Will Not be Consummated; Costs of
Affiliation Transactions

     There can be no assurance that any future affiliation transactions will be
consummated. In consummating future affiliation transactions, the Company will
rely upon certain representations, warranties and indemnities made by sellers
with respect to the affiliation transaction, as well as its own due diligence
investigation.  There can be no assurance that such representations and
warranties will be true and correct, that the Company's due diligence will
uncover all material adverse facts relating to the operations and financial
condition of the affiliated medical practices or that all of the conditions to
the Company's obligations to consummate these future affiliations will be
satisfied.  Any material misrepresentations could have a material adverse effect
on the Company's financial condition and results of operations.

                                       14
<PAGE>
 
     The Company has incurred approximately $2.9 million and $567,000 during
1996 and 1997, respectively, in accounting, legal and other costs in developing
its affiliation structure and completing its initial affiliation transactions.
The Company's ability to enter into affiliation transactions with a significant
number of physicians and to achieve positive cash flow will be adversely
affected unless it is able to reduce the expenses associated with future
transactions. There can be no assurance that the Company will be able to reduce
transaction costs on a per affiliated physician basis in the future.

     Dependence upon Affiliated Medical Practices

     Although the Company does not and will not employ physicians or control the
medical aspects of the practices of the physicians employed by the Springfield
Affiliated Group, the Flagship Affiliated Group or similar Affiliated Groups,
the Company's revenue and profitability are directly dependent on the revenue
generated by the operation and performance of and referrals among the affiliated
medical practices.  The compensation to the Company under its Services
Agreements with the Affiliated Groups is based upon a percentage of the profits
of revenues generated by the Affiliated Groups' practices with a substantial
portion of the profits or revenues being allocated to the physicians until
threshold levels of income or revenues, based upon the physicians' historical
compensation or billings, are achieved.  Accordingly, the performance of
affiliated physicians affected the Company's profitability and the success of
the Company depends, in part, upon an increase in net revenues from the practice
of affiliated physicians compared to historical levels.  The inability of the
Company's Affiliated Groups to attract and retain patients, to manage patient
care effectively and to generate sufficient revenue or a material decrease in
the revenues of the Affiliated Groups would have a material adverse effect on
the financial performance of the Company.  To the extent that the physicians
affiliated with the Company are concentrated in a limited number of target
markets, as is currently the case in western Massachusetts and Maryland,
deterioration in the economies of such markets could have a material adverse
effect upon the Company.

     Risks Related to Expansion of Operations

     Integration Risks.  The Company has completed affiliation transactions with
the Springfield Affiliated Group and the Flagship Affiliated Group, and is
seeking to enter into Affiliates with additional physicians.  In the Springfield
and Greater Baltimore-Annapolis areas and in other potential affiliation
markets, the Company is integrating physician practice groups that have
previously operated independently.  The Company is still in the process of
integrating its affiliated practices.  The Company may encounter difficulties in
integrating the operations of such physician practice groups and the benefits
expected from such affiliations may not be realized.  Any delays or unexpected
cots incurred in connection with integrating such operations could have an
adverse effect on the Company's business, operating results or financial
condition.

     While each Affiliation conforms to PQC's overall business plan, the
profitability, location and culture of the physician practices that have been
combined into Affiliated Groups are different in come respects.  PQC's
management faces a significant challenge in its efforts to integrate and 

                                       15
<PAGE>
 
expand the business of the Affiliated Groups. Because of limited working capital
and operating losses, the Company has recently reduced the size of its corporate
staff. While intended to improve the efficiency and cost of its operations, such
reduction may also make it more difficult for the Company to manage it
operations and growth. The need for management to focus upon such integration
and future Affiliations may limit resources available for the day-to-day
management of the Company's business. While management of the Company believes
that the combination of these practices will serve to strengthen the Company,
there can be no assurance that management's efforts to integrate the operations
of the Company will be successful. The profitability of the Company is largely
dependent on its ability to develop and integrate networks of physicians from
the affiliated practices, to manage and control costs and to realize economies
of scale. There can be no assurance that there will not be substantial costs
associated with such activities or that there will not be other material adverse
effects on the financial results of the Company as a result of these integration
and affiliation activities.

     The Company intends to continue to pursue an aggressive growth strategy
through affiliations and internal development for the foreseeable future.  The
Company's ability to pursue new growth opportunities successfully will depend on
many factors, including, among others, the Company's ability to identify
suitable growth opportunities and successfully integrate affiliated or acquired
businesses and practices.  There can be no assurance that the Company will
anticipate all of the changing demands that expanding operations will impose on
its management, management information systems and physician network.  Any
failure by the Company to adapt its systems and procedures to those changing
demands could have a material adverse effect on the operating results and
financial condition of the Company.

     Need to Hire and Retain Additional Physicians

     The success of the Company is dependent upon its ability to affiliate with
a significant number of qualified physicians and the willingness of such
affiliated physicians to maintain and enhance the productivity of their
practices following affiliation with PQC.  The market for affiliation with
physicians is highly competitive, and the Company expects this competition to
increase.  The Company competes for physician affiliations with many other
entities, some of which have substantially greater resources, greater name
recognition and a longer operating history than the Company and some of which
offer alternative affiliation strategies which the Company may not be able to
offer.  In addition, under current law the Company has no or only limited
ability to enforce restrictive covenants in the employment agreements with the
physicians with whom the Company affiliates.  The Company is subject to the risk
that physicians who receive affiliation payments may discontinue such
affiliation with the Company, resulting in a significant loss to the Company and
decrease in the patient base associated with the such affiliated physicians.
There can be no assurance that PQC will be able to attract and retain a
sufficient number of qualified physicians.  If the Company were unable to
affiliate with an retain a sufficient number of physicians, the Company's
operating results and financial condition would be materially adversely
affected.  A material increase in costs of affiliations could also adversely
affect PQC and its stockholders.

                                       16
<PAGE>
 
     Risk of Inability to Manage Expanding Operations

     The Company is seeking to expand its operations rapidly, which, if
successful, will create significant demands on the Company's administrative,
operational and financial personnel and systems.  There can be no assurance that
the Company's systems, procedures, controls and staffing will be adequate to
support the proposed expansion of the Company's operations. Because of limited
working capital and operating losses, the Company has recently reduced the size
of its corporate staff.  While intended to improve the efficiency and cost of
its operations, such reduction may also make it more difficult for the Company
to manage it operations and growth. The Company's future operating results will
substantially depend on the ability of its officers and key employees to
integrate the management of the Affiliated Groups, to implement and improve
operational, financial control and reporting systems and to manage changing
business conditions.

     Dependence Upon the Growth of Numbers of Covered Lives

     The Company is also largely dependent on the continued increase in the
number of covered lives under managed care and capitate contracts.  This growth
may come from affiliation with additional physicians, increased enrollment with
managed care payors currently contracting with the Affiliated Groups and
additional agreements with managed care payors.  A decline in covered lives or
an inability to increase the number of covered lives under contractual
arrangement with managed care or capitated payors could have a material adverse
effect on the operating results and financial condition of the Company.

     Potential Regulatory Restraints Upon the Company's Operations

     The healthcare industry is subject to extensive federal and state
regulation.  Changes in the regulations or interpretations of existing
regulations could have a material adverse effect on the Company's business,
financial condition and results of operations.

     Risks of Capitated Contracts

     The physician groups with which the Company is affiliated and proposes to
affiliate are parties to certain capitated contracts with third party payors,
such as insurance companies.  The Company intends to seek to expand the
capitated patient base of its Affiliated Groups, particularly for Medicare
enrollees.  In general, risk contracts pay a flat dollar amount per enrollee in
exchange for the physician's obligation to provide or arrange for the provision
of a broad range of healthcare services (including in-patient care) to the
enrollee.  A significant difference between a full risk capitated contract and
traditional managed care contracts is that the physician is sometimes
responsible for both professional physician services and many other healthcare
services, e.g., hospital, laboratory, nursing home and home health.  The
physician is not only the "gatekeeper" for enrollees, but is also financially at
risk for over-utilization and for the actuarial risk that certain patients may
consume significantly more healthcare resources than average for patients of
similar age and sex (such patients are referred to herein as "high risk
patients").

                                       17
<PAGE>
 
     While physicians often purchase reinsurance to cover some of the actuarial
risk associated with high risk patients, such insurance typically does not apply
with respect to the risk of over-utilization until a relatively high level of
aggregate claims has been experienced and therefore does not completely protect
against any capitation risk assumed.  If over-utilization occurs with respect to
a given physician's enrollees (or the physician's panel of enrollees includes a
disproportionate share of high risk patients not covered by reinsurance), the
physician is typically penalized by failing to receive some or all of the
physician's compensation under the contract that is contingent upon the
attainment of negotiated financial targets, or the physician may be required to
reimburse the payor for excess costs.  In addition, a physician may be liable
for over-utilization by other physicians in the same "risk pool" and for
utilization of ancillary, in-patient hospital and other services when the
physician has agreed contractually to manage the use of those services.  Except
for a small amount of coverage maintained by Flagship, neither the Company nor
the Affiliated Groups currently maintain any reinsurance arrangement and, to
date, the Affiliated Groups have not experienced losses from participation in
risk pools or incurred any material penalties or obligations with respect to
excess costs under capitated contracts.  The Company is pursuing a strategy of
seeking increased participation in capitated contracts for all of its affiliated
physicians.  As the percentage of the Company's revenues derived from capitated
contracts increases, the risk of the Company experiencing losses under capitated
contracts increases.  As the revenues from capitated contracts become of
increasing importance to PQC and its Affiliated Groups, the Company will review
the financial attractiveness of reinsurance arrangements.

     Medical providers, such as the Affiliated Groups, are experiencing
increasing pricing pressure in negotiating capitated contracts while facing
increased demands on the quality of their services.  If these trends continue,
the costs of providing physician services could increase while the level of
reimbursement could grow at a lower rate or decrease.  Because the Company's
financial results are dependent upon the profitability of such capitated
contracts, the Company's results will reflect the financial risk associated with
such capitated contracts.  Liabilities or insufficient revenues under capitated
and other risk-sharing arrangements could have a material adverse effect on the
Company.

     Risks of Changes in Payment for Medical Services

     The profitability of the Company may be adversely affected by Medicare and
Medicaid regulations, cost containment decisions of third party payors and other
payment factors over which PQC and its Affiliated Groups have no control.  The
federal Medicare program has undergone significant legislative and regulatory
changes in the reimbursement and fraud and abuse areas, including the adoption
of the resource-based relative value scale schedule for physician compensation
under Medicare, which may have a negative impact on PQC's revenue. Efforts to
control the cost of healthcare services are increasing.  PQC's Affiliated Groups
contract with provider networks, managed care organization and other organized
healthcare systems, which often provided fixed fee schedules or capitation
payment arrangements which are lower than standard charges.  Future
profitability in the changing healthcare environment, with differing methods of
payment for medical services, is likely to be affected significantly by
management of healthcare 

                                       18
<PAGE>
 
costs, pricing of services and agreements with payors. Because PQC derives its
revenues generated by its affiliated physician groups, further reductions in
payment to physicians generally or other changes in payment for healthcare
services could have an adverse effect on the Company.

     Exposure to Professional Liability; Liability Insurance

     In recent years, physicians, hospitals and other participants in the
healthcare industry have become subject to an increasing number of lawsuits
alleging medical malpractice, negligent credentialing of physicians, and related
legal theories.  Many of these lawsuits involve large claims and substantial
defense costs.  There can be no assurance that the Company will not become
involved in such litigation in the future.  Through its management of practice
locations and provision of non-physician healthcare personnel, the Company could
be named in actions involving care rendered to patients by physicians or other
practitioners employed by Affiliated Groups.  In addition, to the extent that
affiliated physicians are subject to such claims, the physicians may need to
devote time to defending such claims, adversely affecting their financial
performance for the Company, and potentially having an adverse effect upon their
reputations and client base.  The Company and the Affiliated Groups maintain
professional and general liability insurance, which is currently maintained at
$1 million per occurrence and $3 million annually for each affiliated physician.
Nevertheless, certain types of risks and liabilities are not covered by
insurance, and there can be no assurance that the limits of coverage will be
adequate to cover losses in all instances.

     Certain Federal Income Tax Considerations

     Physician groups which operated as PCs in Springfield prior to affiliating
with the Company were merged into the Springfield Affiliated Group, with
stockholders of each PC receiving shares of Class A Common Stock of the Company
and cash in exchange for their capital stock in the PC.  Physician groups which
operated as PAs in the greater Baltimore-Annapolis area prior to affiliating
with the Company were similarly merged into the Flagship Affiliated Group, with
stockholders of each PA receiving shares of Class A Common Stock of the Company
and cash in exchange for their capital stock in the PA.  Each such merger is
intended to qualify as a "reorganization" under Section 368(a) of the Internal
Revenue Code of 1986, as amended, in which case no gain or loss would generally
be recognized by the PC or PA or the stockholders (other than as cash received)
of the PC or PA.  The Company has not sought or obtained a ruling form the
Internal Revenue Service or an opinion of counsel with respect to the tax
treatment of the mergers of PCs or PAs into the Springfield or Flagship
Affiliated Groups.  The Company does not believe that the Internal Revenue
Service is issuing rulings at this time on transactions using the Company's
affiliation structure.  If a merger were not to so qualify, the exchange of
shares would be taxable to the stockholders of the PC or PA, and the
consideration (net of asset basis) issued in connection with the merger would be
taxable to the Affiliated Group into which such PC or PA was merged.  Because of
such tax liability, failure of a merger or mergers to qualify as tax-free
reorganizations could have a material adverse effect on the applicable
Affiliated Group and the Company.  Also, the inability to structure future
Affiliations on a tax-deferred basis may adversely affect the Company's ability
to attract additional physicians.

                                       19
<PAGE>
 
     New Management; Dependence on Key Personnel

     The current management structure and the senior management team of the
Company have been in place for a relatively short time. The Company's future
success depends, in large part, on the continued service of its senior
management team, including Jerilyn P. Asher, the Chief Executive Officer, and
Eugene M. Bullis, Senior Vice President and Chief Financial Officer, and the
PQC's ability to continue to attract, motivate and retain highly qualified
senior management and employees. The Company has employment agreements with Ms.
Asher and Mr. Bullis. The Company does not maintain key person life insurance
with respect to Ms. Asher or Mr. Bullis. As a development stage company, PQC has
experienced some turnover in staff, including two of the founding officers.
Although the Company has entered into employment agreements with certain of its
other executives that contain covenants not to compete with the Company, there
can be no assurance that the Company will be able to retain such key executives
or its senior managers and employees. The inability to hire and retain qualified
personnel or the loss of the services of personnel could have a material adverse
effect upon the Company's business and future business prospects.

     Risk of the Unavailability of the Equity Facility

     The remaining amount under the Class B and Class C Stock Purchase Agreement
(the "Equity Facility") with certain institutional investors ("Institutional
Investors") is only available with the consent of the Institutional Investors
and there can be no assurance that the Institutional Investors will be willing
to provide additional capital when needed by the Company.  The Equity Facility
and the Class L Common Stock Purchase Agreement also restrict the sources of
capital available to the Company without the consent of the Institutional
Investors.  Except for the Equity Facility, the Company has no committed
external sources of capital.  Except with the consent of the director elected by
the Institutional Investors, the Company may not obtain additional financing
through external borrowings or the issuance of additional securities.  The
Institutional Investors also have received warrants to purchase a substantial
number of shares of Class A Common Stock.  These warrants, as amended in
connection with the Class L Common Stock financing, are exercisable at $.50 or
$1.25 per share, which exercise price may be substantially below the fair market
value of the Class A Common Stock at the time of exercise. In addition, the
Class L Common Stock is convertible into Class A Common Stock on the basis of a
formula, which would, as of July 15, 1998, result in conversion at least equal
to two shares of Class A Common Stock for each share of Class L Common Stock.
Any additional equity issuance could have an adverse effect on the value of the
shares of Class A Common Stock held by the then existing stockholders.

     Risks from Put and Other Rights Held by Certain Stockholders

     Each physician and management stockholder who is a party to the
Stockholders Agreement, dated as of August 30, 1996 (the "Stockholder's
Agreement"), has the right to require PQC to purchase the Common Stock owned by
such stockholder at fair market value upon their death or disability.  Pursuant
to the Stockholders Agreement, fair market value, as determined by the Board of
Directors, reflects and arm's length private sale.  In determining the fair
market value, the Board is to consider recent arm's length sales by the Company
and the stockholders, as well as other factors 

                                       20
<PAGE>
 
considered relevant. While the Stockholders Agreement does not limit the Board's
discretion, such other factors may include changes, since the last arm's length
sale, in the Company's financial conditions or prospects and any valuation
studies conducted by management of the Company or independent valuation experts.
Under the Stockholder Agreement, the Board is not permitted to discount the fair
market value of the Common Stock to reflect the fact that the Common Stock being
sold constitutes less than a majority of the outstanding shares. The put option
is only triggered by death or disability (and in a few instances retirement) and
will terminate upon the completion of a public offering which results in at
least $50.0 million in gross revenues to the Company and which meets certain
other criteria. The physicians affiliated with Clinical Associates have the
right to require the Company to repurchase their Common Stock at $3.00 per share
(in the form of a five-year, non-interest bearing note) in the event that the
Company has not completed an underwritten initial public offering before
December 1, 2001. The exercise of such right could have a material adverse
effect upon the Company. To the extent that the "put options" are likely to be
exercised, the Company expects to fund such repurchases from working capital,
the Equity Facility or other sources.

     Amortization of Intangible Assets

     In connection with its affiliations, the Company has recorded, and is
expected to continue to record, a significant amount of intangible assets as the
consideration paid to physicians exceeds the value of the practice assets. At
December 31, 1997, the Company had intangible assets of approximately $57.3
million reflected on its balance sheet as long-term affiliation agreements. The
Company amortizes such intangible assets over a 25-year period. See the Notes to
the Company's Financial Statements. The amortization of these intangible assets,
while not affecting the Company's cash flow, has an ongoing negative impact upon
the Company's earnings. Amortization of intangible assets contributed
approximately $1,292,000 to the Company's net loss of $5.7 million during the
year ended December 31, 1997 and $957,000 to the Company's loss of $4.6 million
during the six months ended June 30, 1998.

                               OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS.

     On June 12, 1997, Jay N. Greenberg, a founder and former executive vice
president of the Company, filed a complaint against the Company in Massachusetts
state court seeking damages of $1.4 million and a declaratory judgment that
843,750 of the shares registered in Mr. Greenberg's name (out of 1,012,500
shares of Class A Common Stock originally granted to Mr. Greenberg) have
"vested" under this Employment Agreement.  The Company and Mr. Greenberg entered
into a Settlement Agreement in April 1998 pursuant to which the Company
confirmed Mr. Greenberg granted the Company an option to purchase all of such
shares.  The purchase price is $1.3 million and increases (commencing effective
October 1997) by $25,000 each three-month period.  The option expires on the
earlier of (i) October 14, 1999, (ii) upon a public offering of the capital
stock of the Company, or (iii) a change in control.  No damages were awarded and
mutual releases were granted.

                                       22

ITEM 5.  OTHER INFORMATION

     To address its liquidity needs, the Company issued  2,461,538  shares of
Class L Common Stock to the investors in Class C Common Stock.  The purchase
price was $3.25 for each share of Class L Common Stock for an aggregate purchase
price of approximately $8,000,000. The terms of this round of financing are less
favorable to the Company than the Class C Common Stock financing in June 1997
reflecting the Company's current operating deficits and a general downward
valuation of physician practice management companies ("PPMs") in the
marketplace.

     No distribution, whether as a dividend, upon liquidation or otherwise, may
be made on any other class of Common Stock until the holders of the Class L
Common Stock have received dividends or distributions equal to the purchase
price of the Class L Common Stock plus an amount sufficient to generate an
internal rate of return thereon equal to 12% per annum (compounded).  The
Restated Certificate also limits any distributions on capital stock that
constituted a taxable distribution.

     The Class L Common Stock is a new class of Common Stock. The Class L Common
Stock automatically converts into Class A Common Stock upon the occurrence of
(i) a Qualified Public Offering (as defined in the Restated Certificate), (ii)
upon a merger, consolidation, liquidation or winding up of the Company or a sale
or other transfer of all or substantially all of the Company's assets, or (iii)
if less than 30% of the shares of Class L Common Stock issued in the transaction
remain outstanding, subject, in each case, to approval of two thirds of the
Class B and C Directors, voting as a single class. The Class L Common Stock is
also convertible a any time at the option of the holder.

     The number of shares of Class A Common Stock into which the Class L Common
Stock is convertible is determined pursuant to the formula set forth below.
Based on that formula and assuming no Class L Adjustment, each share of Class L
Common Stock is initially convertible into two shares of Class A Common Stock.
If the full Class L Adjustment is assumed, the Class L Common Stock is initially
convertible into approximately 5 shares of Class A Common Stock. The Class L
Adjustment is made if the Company's Common Stock does not achieve certain
valuations upon a Public Offering or Realization Event. 

     The Class L Conversion Factor (see the Restated Certificate for the meaning
of capitalized terms) is determined as follows:

[Class L Conversion Constant] + [the quotient obtained by dividing the Remaining
Class L Minimum Payment Amount by the Applicable Price per share] + [the Class L
Adjustment].

The Class L Conversion Constant is initially 1 and is adjusted in the event of a
stock split or similar event.

                                       23
<PAGE>
 
     The Remaining Class L Minimum Amount is equal to the Investors' initial
investment in the Class L Common Stock plus an amount sufficient to generate an
internal rate of return equal to 12% per annum (Compounded).

     Applicable Price per Share means, (a) upon the Public Offering, the Public
Offering Price, (b) at the time of any Realization Event, a fraction, the
numerator of which is the excess, if any, of (i) the aggregate value of all
Common Stock of the Company over (ii) the aggregate Remaining Class L
Minimum Payment Amount with respect to all shares of Class L Common Stock
outstanding and the denominator of which is the aggregate number of shares of
Common Stock, (c) at any other time after the Public Offering Time, the Public
Trading Price, and (d) in connection with any optional conversion of Class L
Common Stock, the Public Trading Price, if at such time the Class A Common Stock
is listed on a national securities exchange or traded in the Nasdaq Stock
Market, and, if the Class A Common Stock is not so listed or traded, the greater
of $3.25 per share and the fair market value of each share of Class A Common
Stock as determined in good faith by the Board of Directors.

     The Class L Adjustment is an adjustment to the Class L Conversion Factor
upon the earlier to occur (but only upon the occurrence) of (x) a Realization
Event (i.e., a merger, liquidation or winding up of the Company or a sale of all
or substantially all of its assets) and (y) a public offering. In either such
event, the Class L Conversion Factor is increased by a number equal to, (i) if
the Public Offering Price or the amount distributed to the holders of Class L
Common Stock in such liquidation (together with all prior distributions with
respect to such Class L Common Stock) (the "Class L Value") is equal to or more
than $6.75 per share, 0, (ii) if the Class L Value is equal to or less than
$3.50 per share, 3.12, and (iii) if the Class L Value is less than $6.75 per
share and equal to or greater than $3.50 per share, 0.0096 for each $0.01 that
the Class L Value is less than $6.75.

     Certain provisions of the outstanding Class B Common Stock and Class B and
C Common Stock Warrants  were amended in connection with the Class L financing.
The rights of the Class B Common Stock were amended so that the Class B Common
Stock ranks in parity with the Class C Common Stock in the event of liquidation.
Consequently, in the event of a liquidation, the assets of the Company would
first be used to pay the holders of Class L Common Stock $3.25 per share plus a
cumulative 12% return per annum; the remaining assets, if any, would be used to
pay the holders of Class C Common Stock and Class B Common Stock the greater of
$3.25 and $2.50, respectively, per share and the amount that those shares would
receive if converted to Class A Common Stock.  If any assets remain after those
distributions, they would be available for distribution to the holders of Class
A Common Stock and Class L Common Stock.

     The outstanding warrants to purchase Class C and B Common Stock were also
repriced. The exercise price on the Class B Common Stock Warrants was reduced
from $2.50 to $0.50. The exercise price on the Class C Common Stock Warrants was
reduced from $3.25 to $1.25.

The composition of the Board was amended to provide that ABS Capital Partners II
has the right to appoint two members to the Board of Directors.  The members of
the Board appointed by affiliates of Bain Capital and ABS Capital Partners II
have certain superior voting rights.

                (3) Class B-2 Directors.  The holders of record of outstanding

          shares of Class C Common Stock, voting separately as a single class,

     automatically 

                                      -11-

     will be decreased by the total number of Class B Directors and/or Class C
     Directors, as the case may be.

     A Director, Class B Director, Class C Director and Common Stock Director

     the vote of the holders of a majority of the outstanding shares of the
     class or classes of Common Stock which was entitled to elect the director
     whose office is vacant. The Board of Directors shall be deemed to be duly
     constituted notwithstanding one or more vacancies in its membership,
     whether because of the failure of any class of stockholders to elect the
     full number of directors to which such class is entitled or otherwise. Any
     such vacancy shall automatically reduce the Number of Directors pro tanto,
     until such time as the holders of the class of Common Stock which was
     entitled to elect the director whose office is vacant shall have exercised
     their right to elect a director to fill such vacancy, whereupon the Number
     of Directors shall be automatically increased pro tanto.

     Common Stock Director may be removed without the consent of the holders of
     the class or classes of Common Stock entitled to elect such director.

     Class B and C Director Control Event shall continue in effect, each Class B
     Director and Class C Director shall be entitled to five votes.

     3.6  Stock Splits and Stock Dividends.  The Corporation shall not in any
manner subdivide or increase (whether by stock split, stock dividend or other
similar manner) reclassify or combine in any manner (i) the outstanding shares

Conversion Factor, the Class C Conversion Factor, the Class L Conversion
Constant and the Class L Adjustment or (ii) the outstanding shares of Class B
Common, Class C Common or Class L Common unless a proportional adjustment is
made to the other classes of Common Stock.

          3.7.2 Optional Conversion

                (1) Class B Common Stock.  At the option of any holder of the
          shares of Class B Common Stock, exercisable at any time, in whole or

          holder may be converted into the number of shares of Class A Common
          Stock as determined by application of the Class B Conversion Factor.
          From and after such optional conversion, such shares of Class B Common
          Stock shall be retired and shall not be reissued, and upon the

          holder may be converted into the number of shares of Class A Common
          Stock equal to the Class L Conversion Factor.  From and after such
          optional conversion, such shares of Class L Common Stock shall be

          converted into the number of shares of Class A Common Stock as
          determined by application of the Class C Conversion Factor. From and
          after such optional conversion, such shares of Class C Common Stock
          shall be retired and shall not be reissued, and upon the conversion of
          all outstanding shares of Class C Common Stock and upon the filing of

          (1)  The conversion factor in effect at any time for the Class C
               Common Stock (the "Class C Conversion Factor") shall be the
               quotient obtained by dividing $3.25 by the Class C Conversion
               Value.

          (2)  The Class C Conversion Value shall be $3.25, as adjusted as
               provided below.

               (1)  Upon Sale of Common Stock.  If the Corporation shall, while
                    -------------------------                                  
                    there are any shares of Class C Common Stock outstanding,
                    issue or sell, or be deemed to issue and sell in accordance
                    with this Section 4.7.2(b)(ii), shares after the date hereof
                    of its Common Stock (other than Excluded Securities (as
                    defined below)) without consideration or at a price per
                    share less than the Class C Conversion Value in effect
                    immediately prior to such issuance or sale, then upon each
                    such issuance or sale such Class C Conversion Value, except
                    as provided in Section 4.7.2(b)(ii), shall be lowered so as
                    to be equal to an amount determined by multiplying the Class
                    C Conversion Value by a fraction: (1) the numerator of which
                    shall be (a) the number of shares of Common Stock
                    outstanding immediately prior to the issuance of such
                    additional shares of Common Stock, plus (b) the number of
                    shares of Common Stock which the net aggregate
                    consideration, if any, received by the Corporation for the
                    total number of such additional shares of Common Stock so
                    issued would purchase at the Class C Conversion Value in
                    effect immediately prior to such issuance, and (2) the
                    denominator of which shall be (a) the number of shares of
                    Common Stock outstanding immediately prior to the issuance
                    of such additional shares of Common Stock, plus (b) the
                    number of such additional shares of Common Stock so issued;
                    provided, however, that no adjustment shall be made pursuant
                    to this Clause A unless the consideration received by the
                    Corporation is less than $2.25 per share.

                    Common Stock.
                    ------------ 

                    (1)  For the purpose of this Section 4.7.2(b)(ii), the
                         issuance of any warrants, options, subscriptions or
                         purchase rights with respect to shares of Common Stock
                         and the issuance of any securities convertible into or
                         exchangeable for shares of Common Stock (or the
                         issuance of any warrants, options or any rights with
                         respect to such convertible or exchangeable securities)
                         shall be deemed an issuance at such time of such Common
                         Stock if the Net Consideration Per Share (as
                         hereinafter determined) which may be received by the
                         Corporation for such Common Stock shall be less than
                         the Class C Conversion Value in effect at the time of
                         such issuance.  Any obligation, agreement or
                         undertaking to issue warrants, options, subscriptions
                         or purchase rights at any time in the future shall be
                         deemed to be an issuance at the time such obligation,
                         agreement or undertaking is made or arises.  No
                         adjustment of the Class C Conversion Value for the
                         Class C Common Stock shall be made under this Section
                         4.7.2(b)(ii) upon the issuance of any shares of Common
                         Stock which are issued pursuant to the exercise of any
                         warrants, options, subscriptions or purchase rights or
                         pursuant to the exercise of any conversion or exchange
                         rights in any convertible securities if any adjustment
                         shall previously have been made upon the issuance of
                         any such warrants, options or subscriptions or purchase
                         rights or upon the issuance of any such convertible
                         securities (or upon the issuance of any such warrants,
                         options or any rights therefor) as above.

                         Should the Net Consideration Per Share of any such
                         warrants, options, subscriptions or purchase rights or
                         convertible securities be decreased from time to time
                         then, upon the effectiveness of each such change, the
                         Class C Conversion Value shall be adjusted to such
                         Class C Conversion Value as would have obtained (1) had
                         the adjustments made upon the issuance of such
                         warrants, options, rights or convertible securities
                         been made upon the basis of the actual Net
                         Consideration Per Share of such securities, and (2) had
                         the adjustments made to the Class C Conversion Value
                         since the date of issuance of such 

                                      -16-
<PAGE>
 
                         securities been made to the Class C Conversion Value as
                         adjusted pursuant to (1) above. Any adjustment of the
                         Class C Conversion Value with respect to this paragraph
                         which relates to warrants, options, subscriptions or
                         purchase rights with respect to shares of Common Stock
                         shall be disregarded if, as, and when all of such
                         warrants, options, subscriptions or purchase rights
                         expire or are canceled without being exercised, so that
                         the Class C Conversion Value effective immediately upon
                         such cancellation or expiration shall be equal to the
                         Class C Conversion Value in effect at the time of the
                         issuance of the expired or canceled warrants, options,
                         subscriptions or purchase rights, with such additional
                         adjustments as would have been made to that Class C
                         Conversion Value had the expired or canceled warrants,
                         options, subscriptions or purchase rights not been
                         issued.

                    (2)  For purposes of this paragraph, the "Net Consideration
                         Per Share" which may be received by the Corporation
                         shall be determined as follows: the "Net Consideration
                         Per Share" shall mean the amount equal to the total
                         amount of consideration, if any, received by the
                         Corporation for the issuance of such warrants, options,
                         subscriptions or other purchase rights or convertible
                         or exchangeable securities, plus the minimum amount of
                         consideration, if any, payable to the Corporation upon
                         exercise or conversion thereof, divided by the
                         aggregate number of shares of Common Stock that would
                         be issued if all such warrants, options, subscriptions
                         or other purchase rights or convertible or exchangeable
                         securities were exercised, exchanged or converted and
                         shall be determined in each instance as of the date of
                         issuance of warrants, options, subscriptions or other
                         purchase rights or convertible or exchangeable
                         securities without giving effect to any possible future
                         upward price adjustments or rate adjustments which may
                         be applicable with respect to such warrants, options,
                         subscriptions or other purchase rights or convertible
                         or exchangeable securities.

               (3)  Stock Dividends.  In the event the Corporation shall make or
                    ---------------                                             
                    issue, or shall fix a record date for the determination of
                    holders of any stock of the Corporation other than Common
                    Stock entitled to 

                                      -17-

                    receive a dividend or other distribution payable in Common
                    Stock or securities of the Corporation convertible into or
                    otherwise exchangeable for the Common Stock of the
                    Corporation, then such Common Stock or other securities
                    issued in payment of such dividend shall be deemed to have
                    been issued without consideration, except for (i) dividends
                    payable in shares of Common Stock payable to holders of
                    Class C Common Stock and to holders of any other class of
                    stock, whether or not paid to holders of any other class of
                    stock, (ii) dividends payable in shares of Class C Common
                    Stock; or (iii) dividends payable in Class L Common Stock to
                    the holders of Class L Common Stock so long as, in the case
                    of (i) and (ii) the holders of any shares of Class L Common
                    Stock shall receive such shares of Common Stock and the
                    shares of Class C Common Stock issued as such dividend and
                    payable with respect to the shares into which the Class C
                    Common are convertible.

               (4)  Consideration Other than Cash.  For purposes of this Section
                    -----------------------------                               
                    4.7.2(b)(ii), if a part or all of the consideration received
                    by the Corporation in connection with the issuance of shares
                    of the Common Stock or the issuance of any of the securities
                    described in this Section 4.7.2(b)(ii) consists of property
                    other than cash, such consideration shall be deemed to have
                    a fair market value as is reasonably determined in good
                    faith by the Class B and C Directors, voting together as a
                    single class.

               (5)  Exceptions.  This Section 4.7.2(b)(ii) shall not apply: (1)
                    ----------                                                 
                    to the issuance of shares of Common Stock, or options
                    exercisable therefor, (subject to equitable adjustment in
                    the event of any stock-split, combination, reclassification
                    or other similar event involving the Common Stock) issued
                    and issuable, to officers, employees and consultants of the
                    Corporation or any Affiliate of the Corporation pursuant to
                    any incentive stock option plan or stock purchase plan
                    approved (both as to such plan and as to any issuance of

                    the Board of Directors in accordance with the provisions of
                    this certificate; (2) under any of the circumstances under
                    Section 4.6; (3) to the issuance of shares of Common Stock
                    upon the exchange or exercise of or pursuant to any
                    adjustments provided by any warrants (A) outstanding as of
                    the date hereof or (B) sold to the Investors in connection
                    with the original issuance of shares of Class B Common
                    Stock, Class C Common Stock and/or

                    Class L Common Stock or (4) to the issuance of shares of
                    Class A Common Stock upon the conversion of any shares of
                    Class B Common Stock, Class C Common Stock or Class L Common
                    Stock. The shares issued pursuant to (1) through (4) hereof
                    are collectively referred to herein as the "Excluded
                    Securities."

          3.7.6  Reclassification.  If the Common Stock issuable upon the
     conversion of the Class B Common Stock, Class C Common Stock or Class L
     Common Stock shall be changed into the same or different number of shares
     of any class or classes of stock, whether by reclassification or otherwise
     (other than a subdivision or combination of shares or stock dividend or a
     reorganization, merger or sale of assets provided for elsewhere in this
     Section 4.7, or Section 4.8.6 (to the extent that such transaction is
     treated as a liquidation, dissolution or winding up) or the sale of all or
     substantially all of the Corporation's properties and assets to any other
     person), then and in each such event the holder of each share of Class B
     Common Stock, Class C Common Stock or Class L Common Stock shall have the
     right thereafter to convert such shares into the kind and amount of shares
     of stock and other securities and property receivable upon such
     reclassification or other change by holders of the number of shares of
     Class A Common Stock into which such shares of Class B Common Stock, Class
     C Common Stock or Class L Common Stock might have been converted
     immediately prior to such reclassification or change, all subject to
     further adjustment as provided herein.

          3.7.4  Accountant's Certificate as to Adjustments; Notice by
     Corporation. In each case of an adjustment or readjustment of the Class C
     Conversion Value or upon any calculation of the Class L Conversion Factor,
     the Corporation at its expense will furnish each holder of Class C Common
     Stock or Class L Common Stock, as the case may be, with a certificate,
     prepared by independent public accountants of recognized standing, showing
     such adjustment, readjustment or calculation and stating in detail the
     facts upon which such adjustment, readjustment or calculation is based.

          3.7.5  Cash in Lieu of Fractional Shares.  No fractional shares of
     Common Stock or scrip representing fractional shares shall be issued upon
     the conversion of shares of Class B Common Stock, Class C Common Stock or
     Class L Common Stock.  Instead of any fractional share of Common Stock
     which would otherwise be issuable upon conversion of Class B Common Stock,
     Class C Common Stock or Class L Common Stock, the Corporation shall pay to
     the holder of the shares of Class B Common Stock, Class C Common Stock or
     Class L Common Stock, which were converted, a cash adjustment in respect to
     such fractional shares in an amount equal to the same fraction of the
     market price per share of Common Stock (as determined in a reasonable
     manner prescribed by the Board of Directors), but not less than the
     applicable conversion factor, at the close of business on the conversion
     date.  The determination as to whether or not any fractional shares are
     issuable shall be based upon the total number of shares of Class 

                                      -19-
<PAGE>
 
     B Common Stock, Class C Common Stock or Class L Common Stock being
     converted at any one time by any holder thereof, not upon each share of
     Class B Common Stock, Class C Common Stock or Class L Common Stock being
     converted.

          3.7.6  Reservation of Common Stock; Definitions.  The Corporation
     shall at all times reserve and keep available out of its authorized but
     unissued shares of Class A Common Stock, solely for the purpose of
     effecting the conversion of the shares of Class B Common Stock, Class C
     Common Stock or Class L Common Stock, such number of its shares of Class A
     Common Stock as shall from time to time be sufficient to effect the
     conversion of all outstanding shares of Class B Common Stock, Class C
     Common Stock and Class L Common Stock, and if at any time the number of
     authorized but unissued shares of Class A Common Stock shall not be
     sufficient to effect the conversion of all then outstanding shares of Class
     B Common Stock, Class C Common Stock and Class L Common Stock, the
     Corporation shall take such corporate action as may be necessary to
     increase its authorized but unissued shares of Class A Common Stock to such
     number of shares as shall be sufficient for the purpose.

          3.7.7  Validity of Shares.  The Corporation agrees that it will from
     time to time take all such actions as may be requisite to assure that all
     shares of Common Stock which may be issued upon conversion of any share of
     the Class B Common Stock, Class C Common Stock and Class L Common Stock
     will, upon issuance, be legally and validly issued, fully paid and non-
     assessable and free from all taxes, liens and charges with respect to the
     issue thereof; and, without limiting the generality of the foregoing, the
     Corporation agrees that it will from time to time take all such action as
     may be requisite to assure that the par value per share, if any, of the
     Class A Common Stock is at all times equal to or less than the amount paid
     per share for the Class B Common Stock, Class C Common Stock and Class L
     Common Stock divided by the number of shares of Class A Common Stock into
     which each share of Class B Common Stock, Class C Common Stock and Class L
     Common Stock can, from time to time, be converted.

          3.7.8  Effect of Conversion.  Upon conversion of any share of Class B
     Common Stock, Class C Common Stock or Class L Common Stock, the holder
     shall surrender the certificate evidencing such share to the Corporation at
     its principal place of business.  Promptly after receipt of such
     certificate, the Corporation shall issue and send to such holder a new
     certificate, registered in the name of such holder, evidencing the number
     of shares of Class A Common Stock into which such share has been converted.
     From and after the time of conversion of any share of Class B Common Stock,
     Class C Common Stock or Class L Common Stock, the rights of the holder
     thereof as such shall cease; the certificate formerly evidencing such share
     shall, until surrendered and reissued as provided above, evidence the
     applicable number of shares of Class B Common Stock, Class C Common Stock
     or Class L Common Stock; and such holder shall be deemed to 

                                      -20-

     have become the holder of record of the same number of shares of the Class
     A Common Stock.

     3.8  Distributions.  All Distributions (including on a liquidation,
dissolution or winding-up of the Corporation) shall be made to the holders of
Common Stock in the following order or priority:

          3.8.1  First, the holders of the shares of Class L Common Stock (other
     than shares concurrently being converted into Class A Common Stock), as a
     single and separate class, shall be entitled to receive all Distributions
     until there has been paid with respect to each such share from amounts then
     and previously distributed pursuant to this Article 4.8.1 an amount equal
     to the Class L Base Amount plus an amount sufficient to generate an
     internal rate of return thereon equal to twelve percent (12%) per annum,
     compounded annually.  Such internal rate of return shall be calculated in
     accordance with accepted financial practices, treating the Class L Base
     Amount of each share as having been paid for such share on the date on
     which such share shall have been originally issued by the Corporation and
     each Distribution with respect to the Class L Common Stock as having been
     made on the date it is actually paid by the Corporation.

          3.8.2  Second, if the Distribution is a distribution in liquidation,
     dissolution or winding up of the Corporation and the holders of Class L
     Common Stock have received the distribution provided for in Section 4.8.1,
     the holders of the Class C Common Stock and Class B Common Stock shall be
     entitled to receive prior and in preference to any distribution of any of
     the assets of the Corporation to the holders of Class A Common Stock by
     reason of their ownership of such stock, an amount equal to the sum of (i)
     the greater of (x) $3.25 per share of Class C Common Stock or $2.50 per
     share of Class B Common Stock (which amount, in each case, shall be subject
     to equitable adjustment whenever there shall occur a stock split,
     combination, reclassification or other similar event involving the Class C
     Common Stock) and (y) such amount per share of Class C Common Stock and
     Class B Common Stock which would be payable in such liquidation,
     dissolution or winding up if all outstanding shares of Class C Common Stock
     and Class B Common Stock were converted into Class A Common plus (ii) an
     amount equal to all declared but unpaid dividends thereon, whether or not
     earned, to and including the date full payment shall be tendered to the
     holders of Class C Common Stock and Class B Common Stock with respect to
     such liquidation, dissolution or winding up.  If the assets of the
     Corporation available for distribution shall be insufficient to permit the
     payment in full to such holders of the Class C Common Stock and Class B
     Common Stock of the full aforesaid preferential amount, then the entire
     assets of the Corporation legally available for distribution shall be
     distributed among the holders of the Class C Common Stock and Class B
     Common Stock in the same ratio as the aggregate liquidation preference of
     the outstanding shares of Class C Common Stock and bears to the aggregate
     liquidation preference of the outstanding shares of Class B Common Stock
     held by each of them.

<PAGE>
 
          3.8.3  Third, if the Distribution is a distribution in liquidation,
     dissolution or winding up of the Corporation, after payment has been made
     to the holders of the Class L Common Stock, Class C Common Stock and Class
     B Common Stock of the full amounts to which they shall be entitled as
     aforesaid pursuant to Sections 4.8.1 and 4.8.2, the holders of the Common
     Stock (including the Class L Common Stock but excluding the Class B Common
     Stock and Class C Common Stock) shall be entitled to share ratably in the
     remaining assets, based on the number of shares of Common Stock held by
     them; provided that for purposes of this Section 4.8.3, each share of Class
     L Common Stock shall be deemed to have been converted into the number of
     shares of Class A Common Stock equal to the Class L Conversion Factor.

          3.8.4  Fourth, if the Distribution is not a distribution in
     liquidation, dissolution or winding up of the Corporation after the full
     required amount of Distributions have been made pursuant to Article 4.8.1
     above, all holders of the shares of Common Stock, as a single class, shall
     thereafter be entitled to receive all remaining Distributions pro rata
     based on the number of outstanding shares of Common Stock; provided that
     for purposes of this Section 4.8.4, each share of Class L Common Stock
     shall be deemed to have been converted into a number of shares of Class A
     Common Stock equal to the Class L Conversion Factor.

          3.8.5  All Distributions pursuant to Articles 4.8.1, 4.8.2, 4.8.3 and
     4.8.4 shall be made ratably among the holders of the class or classes of
     Common Stock in question, based on the number of shares of such class held
     by such holders.

          3.8.6  A reorganization of the Common Stock, or a consolidation or
     merger of the Corporation with or into any other corporation or
     corporations in which the stockholders of the Corporation immediately after
     the consolidation or merger do not own more than fifty percent (50%) of the
     outstanding voting power (assuming conversion of all convertible securities
     and the exercise of all outstanding options and warrants) of the surviving
     corporation, or a sale of all or substantially all of the assets of the
     Corporation shall be regarded as a liquidation, dissolution or winding up
     of the affairs of the Corporation within the meaning of Section 4.8, unless
     the holders of a majority of the then outstanding shares of Class B Common
     Stock, Class C Common Stock and Class L Common Stock, voting together as a
     separate class, elect not to treat any of the foregoing events as a
     liquidation, dissolution or winding up by giving written notice thereof to
     the Corporation, at least five (5) business days prior to such event.

     3.9  Prohibition on Distributions Constituting Taxable Events.
Notwithstanding anything to the contrary in this Article 4, the Corporation
shall not, without the written approval of the holders of more than sixty
percent of the shares of Class L Common Stock or, if there is no Class L Common
Stock then outstanding, the holders of a majority of the Class L Common 

                                      -22-
<PAGE>
 
Stock at the time such Common Stock was converted into Class A Common Stock, pay
any dividend or make any other distribution on any share of capital stock, or
take any other action, so long as any share of Class L Common Stock is
outstanding and for three years thereafter, if the effect of such dividend,
distribution or action might be to make (a) an increase of the Remaining Class L
Minimum Payment Amount, (b) a conversion of the Class L Common Stock into Class
A Common Stock or (c) an adjustment of the Class L Conversion Factor a taxable
event to the holders of the Class L Common Stock. No amendment to the provisions
of this Article 4.9 shall be effective without the prior written consent of the
holders of more than sixty percent of the then outstanding shares of Class L
Common Stock or, if there in no Class L Common Stock then outstanding, the
holders of more than sixty percent of the Class L Common Stock at the time such
Common Stock was converted into Class A Common Stock.

     3.10 Preferred Stock.  Preferred Stock may be issued from time to time in
one or more series, each of such series to have such terms as stated or
expressed herein and in the resolution or resolutions providing for the issue of
such series adopted by the Board of Directors of the Corporation as hereinafter
provided subject to the approval of the Class B and C Directors, voting together
as a single class, and compliance with Section 4.9 of this Article Fourth.  Any
shares of Preferred Stock which may be redeemed, purchased or acquired by the
Corporation may be reissued except as otherwise provided by law.  Different
series of Preferred Stock shall not be construed to constitute different classes
of shares for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors, subject to
the approval of the Class B and C Directors, voting together as a single class,
and compliance with Section 4.9 of this Article Fourth, from time to time to
issue the Preferred Stock in one or more series, and in connection with the
creation of any such series, by resolution or resolutions providing for the
issue of the shares thereof, to determine and fix such voting powers, full or
limited, or no voting powers, and such designations, preferences and relative
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, including without limitation thereof, dividend rights,
conversion rights, redemption privileges and liquidation preferences, as shall
be stated and expressed in such resolutions, all to the full extent now or
hereafter permitted by the General Corporation Law of Delaware.  Without
limiting the generality of the foregoing, the resolutions providing for issuance
of any series of Preferred Stock may provide that such series shall be superior
or rank equally or be junior to the Preferred Stock of any other series to the
extent permitted by law.  Except as otherwise provided in this Certificate of
Incorporation, no vote of the holders of the Preferred Stock or Common Stock
shall be a prerequisite to the designation or issuance of any shares of any
series of the Preferred Stock authorized by and complying with the conditions of
this Certificate of Incorporation, the right to have such vote being expressly
waived by all present and future holders of the capital stock of the
Corporation.

     3.11 Replacement. Upon receipt of an affidavit of the registered owner of
one or more shares of any class of Common Stock (or such other evidence as may
be reasonably satisfactory 

                                      -23-
<PAGE>
 
to the Corporation) with respect to the ownership and the loss, theft,
destruction or mutilation of any certificate evidencing such shares of Common
Stock, and in the case of any such loss, theft or destruction, upon receipt of
indemnity reasonably satisfactory to the Corporation (it being understood that
if the holder is an Investor, or any other holder of shares of Common Stock of
the Corporation which is an entity regularly engaged in the business of
investing in companies and meets such requirements of creditworthiness as may
reasonably be imposed by the Corporation in connection with the provisions of
this paragraph, its own agreement will be satisfactory), or, in the case of any
such mutilation upon surrender of such certificate, the Corporation shall
execute and deliver in lieu of such certificate a new certificate of like kind
representing the number of shares of such class represented by such lost,
stolen, destroyed or mutilated certificate and dated the date of such lost,
stolen, destroyed or mutilated certificate.

     3.12  Amendment; Waiver.  No amendment or waiver of any provision of this
Article Fourth shall be effective without the prior written consent of the
holders of more than sixty percent of the then outstanding shares of the Class B
Common Stock, Class C Common Stock and Class L Common Stock, voting as a single
class, and no amendment or waiver of any provision of this Article Fourth which
adversely affects the holders of Class A Common Stock or increases the rights of
the Class B Common Stock, Class C Common Stock and Class L Common Stock shall be
effective without the prior written consent of the holders of a majority of the
then outstanding shares of the Class A Common Stock voting as a single class;
provided, however, that as stipulated in Section 242(b)(2) of the Delaware
General Corporation Law no amendment to any class of Common Stock that alters or
changes the powers, preferences or special rights of such class of Common Stock
so as to affect them adversely shall be effective without the prior consent of
the holders of more than sixty percent of the then outstanding shares of such
class of Common Stock.

     FIFTH:     Except to the extent that the General Corporation Law of
Delaware prohibits the elimination or limitation of liability of directors for
breaches of fiduciary duty, no director of the Corporation shall be personally
liable to the Corporation or its stockholders for monetary damages for any
breach of fiduciary duty as a director, notwithstanding any provision of law
imposing such liability.  No amendment to or repeal of this provision shall
apply to or have any effect on the liability or alleged liability of any
director of the Corporation for or with respect to any acts or omissions of such
director occurring prior to such amendment.

     3.13  Actions, Suits and Proceedings Other than by or in the Right of the
           -------------------------------------------------------------------
Corporation.  The Corporation shall indemnify each person who was or is a party

or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that such person is or was, or is or was serving, or has
agreed to serve, at the request of the Corporation, as a director, officer or
trustee of, or in a similar capacity with, 

                                      -24-
<PAGE>
 
another corporation, partnership, joint venture, trust or other enterprise
(including any employee benefit plan) (all such persons being referred to
hereafter as an "Indemnitee"), or by reason of any action alleged to have been
taken or omitted in such capacity, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person or on such person's behalf in connection with such
action, suit or proceeding and any appeal therefrom, if such person acted in
good faith and in a manner such person reasonably believed to be in, or not
opposed to, the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such person's
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or its
                                                          ---- ----------
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which such person reasonably believed to be
in, or not opposed to, the best interests of the Corporation, and, with respect
to any criminal action or proceeding, had reasonable cause to believe that such
person's conduct was unlawful. Notwithstanding anything to the contrary in this
Article, except as set forth in Section 6.7 below, the Corporation shall not
indemnify an Indemnitee seeking indemnification in connection with a proceeding
(or part thereof) initiated by the Indemnitee unless the initiation thereof was
approved by the Board of Directors of the Corporation. Notwithstanding anything
to the contrary in this Article, the Corporation shall not indemnify an
Indemnitee to the extent such Indemnitee is reimbursed from the proceeds of
insurance, and in the event the Corporation makes any indemnification payments
to an Indemnitee and such Indemnitee is subsequently reimbursed from the
proceeds of insurance, such Indemnitee shall promptly refund such
indemnification payments to the Corporation to the extent of such insurance
reimbursement.

     3.14 Actions or Suits by or in the Right of the Corporation.  The
          ------------------------------------------------------      
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that such person is or was, or has agreed to become, a
director or officer of the Corporation, or is or was serving, or has agreed to
serve, at the request of the Corporation, as a director, officer or trustee of,
or in a similar capacity with, another corporation, partnership, joint venture,
trust or other enterprise (including any employee benefit plan), or by reason of
any action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by such person or on
such person's behalf in connection with such action, suit or proceeding and any
appeal therefrom, if such person acted in good faith and in a manner reasonably
believed to be in, or not opposed to, the best interests of the Corporation,
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
Corporation unless and only to the extent that the Court of Chancery of Delaware
shall determine upon application that, despite the adjudication of such
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses (including
attorneys' fees) which the Court of Chancery of Delaware shall deem proper.

     3.15 Indemnification for Expenses of Successful Party.  Notwithstanding the
          ------------------------------------------------                      
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 6.1 and 6.2 of this Article, or in defense of
any claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, the Indemnitee shall be indemnified against all expenses (including
attorneys' fees) actually and reasonably incurred by the Indemnitee or on the
Indemnitee's behalf in connection therewith. Without limiting the foregoing, if
any action, suit or proceeding is disposed of, on the merits or otherwise
(including a disposition without prejudice), without (i) the disposition being
adverse to the Indemnitee, (ii) an adjudication that the Indemnitee was liable
to the Corporation, (iii) a plea of guilty or nolo contendere by the Indemnitee,
                                              ---- ----------                   
(iv) an adjudication that the Indemnitee did not act in good faith and in a
manner the Indemnitee reasonably believed to be in or not opposed to the best
interests of the Corporation, and (v) with respect to any criminal proceeding,
an adjudication that the Indemnitee had reasonable cause to believe the
Indemnitee's conduct was unlawful, the Indemnitee shall be considered for the
purposes hereof to have been wholly successful with respect thereto.

     3.16 Notification and Defense of Claim.  As a condition precedent to the
          ---------------------------------                                  
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving the Indemnitee for which indemnity will or could be sought.  With
respect to any action, suit, proceeding or investigation of which the
Corporation is so notified, the Corporation will be entitled to participate
therein at its own expense and/or to assume the defense thereof at its own
expense, with legal counsel reasonably -acceptable to the Indemnitee.  After
notice from the Corporation to the Indemnitee of its election so to assume such
defense, the Corporation shall not be liable to the Indemnitee for any legal or
other expenses subsequently incurred by the Indemnitee in connection with such
claim, other than as provided below in this Section 6.4.  The Indemnitee shall
have the right to employ the Indemnitee's own counsel in connection with such
claim, but the fees and expenses of such counsel incurred after notice from the
Corporation of its assumption of the defense thereof shall be at the expense of
the Indemnitee unless (i) the employment of counsel by the Indemnitee has been
authorized by the Corporation, (ii) counsel to the Indemnitee shall have
reasonably concluded that there may be a conflict of interest or position on any
significant issue between the Corporation and the Indemnitee in the conduct of
the defense of such action or (iii) the Corporation shall not in fact have
employed counsel to assume the defense of such action, in each of which cases
the fees and expenses of counsel for the Indemnitee shall be at the expense of
the Corporation, except as otherwise expressly provided by this Article.  The
Corporation shall not be entitled, without the consent of the Indemnitee, to
assume the defense of any claim brought by or in the right of the Corporation or
as to which counsel for the Indemnitee shall have reasonably made the conclusion
provided for in clause (ii) above.

     3.17 Advance of Expenses.  Subject to the provisions of Section 6.6 below,
          -------------------                                                  
in the event that the Corporation does not assume the defense pursuant to
Section 6.4 of this Article of any 

                                      -26-
<PAGE>
 
action, suit, proceeding or investigation of which the Corporation receives
notice under this Article, any expenses (including attorneys' fees) incurred by
an Indemnitee in defending a civil or criminal action, suit, proceeding or
investigation or any appeal therefrom shall be paid by the Corporation in
advance of the final disposition of such matter; provided, however, that the
payment of such expenses incurred by an Indemnitee in advance of the final
- --------  -------                                                             
disposition of such matter shall be made only upon receipt of an undertaking by
or on behalf of the Indemnitee to repay all amounts so advanced in the event
that it shall ultimately be determined that the Indemnitee is not entitled to be
indemnified by the Corporation as authorized in this Article. Such undertaking
shall be accepted without reference to the financial ability of the Indemnitee
to make such repayment.

     3.18 Procedure for Indemnification.  In order to obtain indemnification or
          -----------------------------                                        
advancement of expenses pursuant to Section 6.1, 6.2, 6.3 or 6.5 of this
Article, the Indemnitee shall submit to the Corporation a written request,
including in such request such documentation and information as is reasonably
available to the Indemnitee and is reasonably necessary to determine whether and
to what extent the Indemnitee is entitled to indemnification or advancement OF
expenses.  Any such indemnification or advancement of expenses shall be made
promptly, and in any event within 60 days after receipt by the Corporation of
the written request of the Indemnitee, unless with respect to requests under
Section 6.1, 6.2 or 6.5 the Corporation determines within such 60-day period
that the Indemnitee did not meet the applicable standard of conduct set forth in
Section 1 or 2, as the case may be. Such determination shall be made in each
instance by (a) a majority vote of the directors of the Corporation consisting
of persons who are not at that time parties to the action, suit or proceeding in
question ("disinterested directors"), whether or not a quorum, (b)a majority
vote of a quorum of the outstanding shares of stock of all classes entitled to
vote for directors, voting as a single class, which quorum shall consist of
stockholders who are not at that time parties to the action, suit or proceeding
in question, (c) independent legal counsel (who competent jurisdiction.

     3.19 Remedies.  The right to indemnification or advances as granted by this
          --------                                                              
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6.6.  Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation.  Neither the failure of the
Corporation to have made a determination prior to the commencement of such
action that indemnification is proper in the circumstances because the
Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Corporation pursuant to Section 6.6 that the Indemnitee has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the Indemnitee has not met the applicable standard of
conduct.  The Indemnitee's expenses (including attorneys' fees) incurred in
connection with successfully establishing the Indemnitee's right to
indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

     3.20 Subsequent Amendment.  No amendment, termination or repeal of this
          --------------------                                              
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such

its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by such person in any such capacity, or arising out
of such person's status as such, whether or not the Corporation would have the

          --------------                                                 
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right OF the
portion OF this Article that shall Corporation, to the fullest extent permitted
by any applicable not have been invalidated and to the fullest extent permitted
by applicable law.

     3.26 Definitions.  Terms used herein and defined in Section 145(h) and
          -----------                                                      
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     3.27 Subsequent Legislation.  If the General Corporation Law of Delaware is
          ----------------------                                                
amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     SEVENTH:   The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted

Incorporation or these By-laws, the holders of a majority of the shares (or, if
there are two or more classes of stock entitled to vote as separate classes, the
holders of a majority of the shares of such class) of the capital stock of the
corporation issued and outstanding and entitled to vote at the meeting, present
in person or represented by proxy, shall constitute a quorum for the transaction
of business.

     1.7. Adjournments.  Any meeting of stockholders may be adjourned to any

other time and to any other place at which a meeting of stockholders may be held
under these Bylaws by the stockholders present or represented at the meeting and
entitled to vote, although less than a quorum, or, if no stockholder is present,

in person or may authorize another person or persons to vote or act for him by

(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws.  When a quorum is present at any meeting, any
election of directors by stockholders shall be determined by a majority of the
votes cast on the election.

     Proposal by its terms shall remain open and irrevocable for a period of 20
     days from the date it is delivered by the Company to each Investor (the
     "Future Securities Exercise Period").  The Proposal shall also certify that

                                                                       ---------
     Purchase"). If the total number of Future Securities is sufficient to
     --------
     satisfy the elections of Investors contained in the Notices to Purchase
     such Future Securities shall be allocated in accordance with their
     elections; if not the available Future Securities shall be allocated among
     the Investors in proportion to their election, provided, however, such
     allocation shall be adjusted if necessary so that no Investor is allocated
     more Future Securities than it has elected to purchase.

          6.12.4  Sale to Third Parties. In the event that the Investors elect
                  ---------------------
     not to purchase all (or any part) of the Future Securities, the Company
     shall have 120 days from the expiration of the Future Securities Exercise
     Period to offer and sell all or any part of such Future Securities not
     purchased by the Investors (the "Refused Future Securities") to any other
                                      -------------------------
     Person(s), but only upon terms and conditions in all respects (including,

     Person(s) or their affiliates identified in the Proposal, if so identified
     pursuant to Section 6.13.2. In the event that the Company so sells the
     Refused Future Securities to such other Person(s), the sale to each
     Investor of the Future Securities in respect of which a Notice of Purchase
     was delivered to the Company by such Investor shall occur upon the closing

or provoking his resignation;

          (ii)      any reduction in Dr. Frank's annual base salary or a
material reduction in fringe benefits in effect on the effective date or as the
same may be increased during the Term;

          (iii)     any material breach by the Company of this Agreement which

          (i) severance for two years at the annual rate of $125,000 plus

severance amounts payable to Dr. Frank upon a discharge or termination as
specified in this Section 11 will constitute full, reasonable and adequate
compensation for any such termination and that the payment of such compensation

Agreement shall terminate upon the effective date of the termination of
employment; provided, however, the Company shall pay Dr. Frank any base salary

notice of such termination as of a date (not earlier than 10 days after such
notice) to be specified in such notice, and his employment hereunder shall
terminate on the date so specified.

          (b) For purposes of this Section 13, "Cause" shall mean (i) Dr.
Frank's material failure to perform his duties with the Company as set out in
Exhibit A (other than any such failure resulting from his incapacity due to

which is not remedied within 30 days as specified in a written demand for
performance; (ii) intentional misconduct materially and demonstrably injurious
to the Company, or (iii) Dr. Frank's conviction of a felony or of fraud or

and until there shall have been delivered to him a copy of a

                                      -9-

resolution, duly adopted by the affirmative vote of not less than two-thirds of
the entire membership of the Board of the Company at a meeting called and held

Dr. Frank will receive severance equal to his annual base salary then in effect,
payable in 12 equal monthly installments beginning 30 days after termination of
this Agreement and provided that such installment payments shall accelerate and

his capacity as an officer of the Company to the full extent permitted by

     17.  Non-Compete.
          ----------- 
          (a) So long as Dr. Frank is employed by the Company and for a period

officer, employee, director, joint venturer, investor, lender, or in any other
capacity whatsoever (other than as the holder of not more than one percent (1%)
of the total Outstanding stock of a publicly held company), engage directly or

Frank's right to practice medicine or treat patients.

          (b) If any restriction set forth in this Section 17 is found by any
court of competent jurisdiction to be unenforceable because it extends for too

area as to which it may be enforceable.

          (c) The restrictions contained in this Section 17 are necessary for
the protection of the business and goodwill of the Company and are considered by
Dr. Frank to be reasonable for such purpose. Dr. Frank agrees that any breach of
this Section 17 will cause the Company substantial and irrevocable damage and

          (3)  In the event that Dr. Calvanese's employment is terminated under
this Section 15, all options to purchase the Company's Common Stock granted
under this Agreement shall vest on the termination date.  Dr. Calvanese shall
then have the full and immediate right to receive all such shares upon full

     16.  Indemnification.  The Company hereby agrees to indemnify Dr. Calvanese
          ---------------                                                       
in his capacity as an officer of the Company to the full extent permitted by
Delaware law and the Company's restated articles of incorporation.

     17.  Non-Compete.
          ----------- 

          (1) So long as Dr. Calvanese is employed by the Company and for a
period of two years after the termination or expiration of his employment, he
will not directly or indirectly: (i) as an individual proprietor, partner,
stockholder, officer, employee, director, joint venturer, investor, lender, or
in any other capacity whatsoever (other than as the holder of not more than one
percent (1%) of the total outstanding stock of a publicly held company), engage
directly or indirectly in any business or entity in Massachusetts which
operates, develops or manages physician practice management entities to the
extent such engagement assists through a management position such business or
entity in directly and substantially competing with the business conducted by
the Company in Massachusetts; or (ii) recruit, solicit or induce, or attempt 

                                      -14-
<PAGE>
 
to induce, any employee or employees of the Company to terminate their
employment with, or otherwise cease their relationship with, the Company; or
(iii) solicit, divert or take away, or attempt to divert or to take away, the
business or patronage in Massachusetts of any of the clients, customers or
accounts, or prospective clients, customers or accounts, of the Company which
were contacted, solicited or served by Dr. Calvanese while employed by the
Company. Nothing in this Agreement shall restrict Dr. Calvanese's right to
practice medicine or treat patients.

          (2)  If any restriction set forth in this Section 17 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

          (3)  The restrictions contained in this Section 17 are necessary for
the protection of the business and goodwill of the Company and are considered by
Dr. Calvanese to be reasonable for such purpose.  Dr. Calvanese agrees that any

purposes of this Agreement, considered as though such person were a member of
the Incumbent Board, excluding any individual whose initial assumption of office
occurs as a result of an actual or threatened election contest with respect to
the election or removal of directors or other actual or threatened solicitation
of proxies or consents by or on behalf of a Person other than the Board; or

          (iii) the stockholders of the Company approve a reorganization,

prior to the Business Combination and (C) at least a majority of the members of
the Board of Directors of the corporation resulting from such Business
Combination were members of the Incumbent Board at the time of the execution of
the initial agreement, or of the action of the Board, providing for such

     (c)  In the event the Employee's employment is terminated under this
Section 15, all stock options for the purchase of the Company's Common Stock
granted to the Employee by the Company under any of the Company's stock option
plans or under this Agreement or any stock restriction agreement then in effect
shall vest on the termination date. The Employee shall then have the full and
immediate right to exercise all additional stock options.

     16.  Indemnification.  The Employee shall be fully indemnified by the
          ---------------                                                 
Company as a senior official of the Company to the extent permitted by Delaware

     (a)  So long as the Employee is employed by the Company and for a period of
one year after the termination or expiration of employment, the Employee will
not directly or indirectly: (i) as an individual proprietor, partner,
stockholder, officer, employee, director, joint venturer, investor, lender, or
in any other capacity whatsoever (other than as the holder of not more than one
percent (1%) of the total outstanding stock of a publicly held company), engage
directly or indirectly in any business or entity which operates, develops or
manages physician practice management entities to the extent such engagement
assists such business or entity in competing with the business conducted by the
Company in any city or geographic area in which the Company or its affiliates
conduct material operations at the time of termination of employment under this
Agreement; or (ii) recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company; or (iii) solicit, divert
or take away, or attempt to divert or to take away, the business or patronage of
any of the clients, customers or accounts, or clients, customers or accounts, of
the Company which were contacted, solicited or served by the Employee while
employed by the Company.

     (b)  If any restriction set forth in this Section 17 is found by any court
of competent jurisdiction to be unenforceable because it extends for too long a
period of time or over too great a range of activities or in too broad a
geographical area, it shall be interpreted to extend only over the maximum
period of time, range of activities or geographic area as to which it may be
enforceable.

     (c)  The restrictions contained in this Section 17 are necessary for the
protection of the business and goodwill of the Company and are considered by the
Employee to be reasonable for 

                                       10
<PAGE>
 
such purpose. The Employee agrees that any breach of this Section 17 will cause
the Company substantial and irrevocable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, the
Company shall have the right to seek specific performance and injunctive relief.

until such Proprietary Information has become public knowledge without fault by
the Employee.

          (ii) The Employee agrees that all files, letters, memoranda, reports,
records, data, sketches, drawings, laboratory notebooks, program listings, or
other written, photographic, or other tangible material containing Proprietary

exclusive property of the Company to be used by the Employee only in the
performance of duties for the Company.

          (iii) The Employee agrees that the obligation not to disclose or
use information, know-how and records of the types set forth in Subsection (a)
of this Section 18, also extends to such types of information, know-how, records
and tangible property of customers of the Company or suppliers to the Company or
other third parties who may have disclosed or entrusted the same to the Company
or to the Employee in the course of the Company's business.

          (iv)  Notwithstanding anything to the contrary in Section 18(a), the
Company recognizes that the Employee has joined the Company with certain know-
how, skill, experience, expertise, information, and analytical capabilities

conceived or reduced to practice by the Employee or under the Employee's
direction or jointly with others during employment by the Company, whether or
not during normal working hours or on the premises of the Company (all of which
are collectively referred to in this Agreement as "Developments").

          (ii)  The Employee agrees to assign and does hereby assign to the
Company (or any person or entity designated by the Company) all right, title and
interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications.

                                       12

          Subsection (b) of this Section 18 shall not apply to any intellectual
work which is not related to the present or planned business or research and
development of the Company and which is made and conceived by the Employee
outside work and not on the Company's premises and not using the Company's
tools, devices, equipment, intellectual property, or Developments.  It is
expressly understood and agreed that the Employee shall have the obligation to
demonstrate that any such intellectual work is not related to the present or
planned business or research and development of the Company and has been made
and conceived by the Employee outside work and not on the Company's premises and
not using the Company's tools, devices, equipment, intellectual property, or
Developments.

          (iii) The Employee agrees to cooperate fully with the Company, both
during and after employment with the Company, with respect to the procurement,
maintenance and enforcement of copyrights and patents (both in the United States
and foreign countries) relating to Developments. The Employee shall sign all
papers, including, without limitation, copyright applications, patent
applications, declarations, oaths, formal assignments, assignment of priority
rights, and powers of attorney, which the Company may reasonably deem necessary
or desirable in order to protect its rights and interests in any Development.

     (c)  Other Agreements.  The Employee represents that performance of all the
          ----------------                                                   
terms of this Agreement as an employee of the Company does not and will not
breach any agreement to keep in confidence proprietary information, knowledge or
data acquired by the Employee in confidence or in trust prior to employment with
the Company.

     19.  Assignment.  Neither this Agreement nor any rights or benefits
          ----------                                                      
hereunder shall be subject to execution, attachment or similar process; nor may
this Agreement or any rights or 

                                       13
<PAGE>
 
benefits hereunder be assigned, delegated, transferred, pledged or hypothecated,
without the written consent of both parties hereto, and any such assignment,
delegation, transfer, pledge, hypothecation, execution, attachment or similar
process shall be null and void.

     20.  Successors; Binding Agreement.

          (a) The Company shall require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company to assume expressly
in writing and to agree to perform its obligations under this Agreement in the
same manner and to the same extent that the Company would be required to perform
it if no such succession had taken place.  Failure of the Company to obtain an
assumption of this Agreement prior to the effectiveness of succession shall be a
breach of this Agreement.  As used in this Agreement, "the Company" shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

          (b) This Agreement shall inure to the benefit of and be enforceable by
the Employee's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.  Any amounts payable by
the Company to the Employee after the date of death, unless otherwise provided
here, shall be paid in accordance with the terms of this Agreement to the
Employee's devisee, legatee or other designee, or if there is no such designee,
to the Employee's estate.

     21.  Severability.  Whenever possible, each provision of this Agreement
          ------------                                                     
shall be interpreted in such manner as to be valid and effective under
applicable law, but if any provision of this Agreement is found to be prohibited
or invalid under applicable law, such provision shall 

                                       14
<PAGE>
 
be ineffective to the extent of such prohibition or invalidity without
invalidating the remainder of such provision or the remaining provisions of this
Agreement.

to be delivered by giving the other parties in the manner set out here.

     23.  Waiver and Modification.  Any waiver, alteration or modification of
          -----------------------

constitute one and the same instrument.
