Item 2:        ACQUISITION OR DISPOSITION OF ASSETS
               ------------------------------------
GENERAL

     On June 19, 1996, PRI Merger Company, Inc., a Delaware corporation and a
wholly owned subsidiary of VCA merged with and into Pets' Rx, Inc.,
a Delaware corporation ("Pets' Rx") resulting in Pets' Rx becoming a wholly
owned subsidiary of VCA.  Pets' Rx is the owner and operator of 16
veterinary hospitals located in Las Vegas, Nevada and Northern California.  The
Merger provides VCA with entry into the Las Vegas, Nevada market and
strengthens the Registrant's presence in Northern California.

     The outstanding securities of Pets' Rx were converted into 801,081 shares
of VCA Common Stock.  The closing sale price of the VCA Common Stock on June
19, 1996 was $26.00 per share.  There was no prior affiliation between VCA and 
Pets' Rx, and the determination of the consideration paid was made by arm's 
length negotiation between the parties.

     Attached hereto as Exhibit 7.2 is Registrant's press release, issued June
20, 1996, which is incorporated in its entirety by this reference.

RECENT DEVELOPMENTS

     Since January 1, 1996 through June 20, 1996, VCA has acquired 11 animal
hospitals in the states of Maryland, Massachusetts, Pennsylvania, Florida,
Hawaii and California.  In addition, VCA has acquired three veterinary
diagnostic laboratories including Southwest Veterinary Diagnostics, Inc.
("Southwest"), a veterinary diagnostic laboratory located in Phoenix, Arizona. 
The acquisition of Southwest, which services more than 1,900 veterinary
hospitals in the states of Arizona, California, New Mexico, Texas, Kansas,
Nebraska and Missouri, and other portions of the Midwest, expands the customer
base of VCA's laboratory division, providing VCA with the opportunity to serve
over 8,000 veterinary hospitals daily.  In connection with the acquisitions, 
which were accounted for as a purchase VCA paid an aggregate consideration 
of $28,718,000 consisting of $13,614,000 in cash, $8,066,000 in debt, 
242,926 shares of VCA Common Stock, with a value of $3,868,000, and the 
assumption of liabilities totaling $3,170,000, including acquisition costs.  
In connection with the acquisitions which were treated as a poooling of 
interests, VCA issued 151,010 shares of VCA Common Stock.

<PAGE>

PET PRACTICE

     On March 21, 1996, VCA signed a definitive merger agreement with The Pet
Practice, Inc. ("Pet Practice"), pursuant to which VCA may acquire all of the
outstanding securities of Pet Practice.  Pet Practice operates 84 veterinary
hospitals in 11 states.

     The merger agreement with Pet Practice may be terminated by either VCA or
Pet Practice at any time prior to the closing (i) if any material condition to
the obligations of VCA or Pet Practice set forth in the merger agreement is not
substantially satisfied at the time or times contemplated thereby, (ii) if there
is a material breach of any representation, warranty, condition or agreement
contained in the merger agreement (that is not cured within 30 days of the time
that written notice of such breach is received by the breaching party), (iii)
if the merger shall not have been consummated on or before September
1, 1996, or (iv) upon their mutual consent.  There can be no assurance that the
Pet Practice Merger will be consummated or if consummated, that the operations
will be successfully integrated.  See "Risk Factors - Pending Transactions."

DEBT OFFERING

     On April 17, 1996, VCA issued $84.4 million of 5.25% convertible
subordinated debentures (the "Debentures") due in 2006.  The Debentures, non-
callable for three years, will be convertible into approximately 2.5 million
shares of VCA Common Stock at a rate of $34.35 per share.  The proceeds of this
offering are intended to be used to repay long-term related debt and for
general corporate purposes.

<PAGE>

RISK FACTORS

PENDING TRANSACTIONS

     VCA entered into the merger agreement with Pet Practice (the
"Pet Practice Merger") and acquired Pets' Rx with the expectation that the
transactions will result in beneficial synergies for the combined business. 
These include the potential to realize improved operating margins at animal
hospitals through a strategy of centralizing various corporate and
administrative functions and leveraging fixed costs while providing customers
with improved services.  

     Achieving these anticipated business benefits will depend in part on
whether the operations of Pet Practice and Pets' Rx, or either of them, can be
integrated with the operations of VCA in an efficient, effective and timely
manner.  There can be no assurance that this will occur.  The combination of
two or three of the companies will require, among other things, integration of
the companies' management staffs, coordination of the companies' sales and
marketing efforts, integration and coordination of the companies' development
teams and the identification and elimination of redundant and/or unnecessary
overhead and poor-performing hospitals.  The success of this process will be 
<PAGE>
significantly influenced by the ability of the combined business to retain key
management and marketing and development personnel.  There is no assurance that
this integration will be accomplished smoothly or successfully or that VCA will
be successful in retaining key members of management.  The difficulties of such
integration may be increased by the necessity of coordinating geographically
separated organizations with distinct cultures.  The integration of operations
of two or three of the companies following the mergers will require the
dedication of management resources, which may temporarily distract attention
from the day-to-day business of the combined business.  The inability of
management to integrate successfully the operations of two or three of the
companies could have an adverse effect on the business and results of the
combined business.  In addition, even if the operations of the three companies
are ultimately successfully integrated, it is anticipated that the integration
will be accomplished over time and, in the interim, the combination may have an
adverse effect on the business, results of operations and financial condition
of the combined business.

     In addition, there can be no assurance that the present and potential
customers of VCA, Pet Practice and Pets' Rx will continue their current
utilization patterns without regard to the proposed mergers or that the
proposed mergers will not have an adverse impact upon relationships with
veterinarians and other animal health care professionals currently employed by
VCA, Pet Practice and Pets' Rx.  Any significant reduction in utilization
patterns by VCA, Pet Practice and Pets' Rx's customers, or any significant
adverse impact on relationships with the veterinarians and other animal health
care professionals currently employed by VCA, Pet Practice or Pets' Rx, could
have an adverse effect on the near-term business and results of operations of
the combined business.

     Pet Practice commenced operations in October 1993, although the initial
business Pet Practice acquired has, and most of the veterinary hospitals
acquired since have, operated over a substantial period.  Pet Practice had net
losses of $4,888,000 in fiscal 1994, $3,175,000 in fiscal 1995 and $899,000 for
the thirteen weeks ended April 3, 1996 and an accumulated deficit of $9,591,000
as of April 3, 1996 relating to net losses in the period from October 27, 1993
(commencement of operations) through December 29, 1993, fiscal 1994 and 1995
and the thirteen weeks ended April 3, 1996.  In view of Pet Practice's
significant recent growth and the impact of certain charges on Pet Practice's
1994 and 1995 results, Pet Practice's historical financial performance may not
be indicative of its future performance.  There can be no assurance that Pet
Practice will achieve profitability or successfully implement its business
strategy.  

     Pets' Rx commenced operations on May 28, 1991.  Pets' Rx had net losses of
approximately $2,805,000 in fiscal 1994, $1,977,000 in fiscal 1995 and $358,000
for the three months ended March 31, 1996 and an accumulated deficit of
$8,505,000 as of March 31, 1996.  Further losses are expected to be recorded
for fiscal 1995 and 1993 as a result of anticipated pooling adjustments.  In 
view of Pets' Rx's recent growth and the impact of nonrecurring charges and 
certain other charges on Pets' Rx's 1994 and 1995 results, Pets' Rx's 
historical financial performance may not be indicative of its future 
performance.  There can be no assurance that Pets' Rx will achieve 
profitability or successfully implement its business strategy.

<PAGE>

ANTICIPATED EFFECTS OF ACQUISITIONS

     VCA is currently evaluating the operations of the businesses of Pet
Practice and Pets' Rx for purposes of developing a plan for the integration of
the businesses to be acquired with VCA's existing operations.  Although this
plan is not yet complete, it is anticipated that a significant restructuring of
the combined operations will be required as a result of the mergers.  As a
consequence of this restructuring and the consummation of the mergers, VCA
anticipates incurring one-time restructuring and related charges in the second
and/or third quarters of 1996.  The magnitude of these charges has not been
quantified at this time.

     The Pets' Rx acquisition is intended to be accounted for on a pooling of
interests basis.  Under the pooling rules, the historical financial results of
VCA will be restated to reflect the combination, following certain adjustments. 
Pets' Rx incurred a loss in each of the three fiscal years ended December 31,
1995 and in the first quarter ended March 31, 1996.  Following the consummation
of the merger, the historical results of VCA will be restated to reflect the
historical losses of Pets' Rx.  In addition, Pets' Rx is expected to continue
to incur losses in the second quarter of 1996.  Further, under the pooling
rules, the costs incurred by VCA and Pets' Rx in consummating the merger will
be expensed during the second quarter.

     The Pet Practice Merger is intended to be accounted for as a purchase. 
Under the purchase rules, the Pet Practice Merger is expected to result in a
significant increase in the goodwill and other intangibles recorded on VCA's
balance sheet.  This increase in goodwill and other intangibles will be in
addition to the increase resulting from the combination with Pets' Rx, which
also has significant goodwill and other intangibles recorded on its balance
sheet.  As a result, VCA expects that its amortization expense will
significantly increase over historical levels.

     The combined effect of the restructuring and other charges discussed
above, the pooling treatment in the Pets' Rx acquisition and the increased
amortization expense will have an adverse effect on the results of operations
of VCA in each of the second and third quarters of 1996.  Further, the effect
of the increased amortization expense is expected to temper reported earnings
of VCA in the fourth quarter and subsequent periods.  

RAPID EXPANSION AND MANAGEMENT OF GROWTH

     Due to the number and size of acquisitions completed since January 1,
1994, VCA and Pet Practice have experienced rapid growth.  In 1994, VCA
completed six acquisitions (five animal hospitals and one veterinary diagnostic
laboratory) and in 1995, VCA completed 32 acquisitions (25 animal hospitals,
six veterinary diagnostic laboratories and the remaining 30 percent interest in
Professional Animal Laboratory ("PAL")).  As a result of these acquisitions,
VCA's revenues have grown from $25.3 million in 1993 to $42.2 million in 1994
and to $92.1 million in 1995.  In addition, during this period, VCA entered two
new lines of business, veterinary diagnostic laboratories and premium pet food.

<PAGE>

     In 1994, Pet Practice acquired 30 veterinary hospitals and in 1995, Pet
Practice acquired 38 veterinary hospitals.  As a result of these acquisitions,
Pet Practice's revenues have grown from $1.2 million in the period from October
27, 1993 to December 29, 1993 to $15.1 million in fiscal 1994 and to $40.6
million in fiscal 1995.

     VCA's and Pet Practice's growth and pace of acquisitions have placed, and
will continue to place, a substantial strain on their respective management,
operational, financial and accounting resources.  The successful management of
this growth will require VCA and Pet Practice to continue to implement and
improve their respective financial and management information systems and to
train, motivate and manage their respective employees.  There can be no
assurance that the combined business will be able to identify, consummate or
integrate acquisitions without substantial delays, costs or other problems. 
Once integrated, acquisitions may not achieve sales, profitability and asset
productivity commensurate with the combined business' other operations.  In
addition, acquisitions involve several other risks, including adverse short-
term effects on the combined business' reported operating results, impairments
of goodwill and other intangible assets, the diversion of management's
attention, the dependence on retention, hiring and training of key personnel,
the amortization of intangible assets and risks associated with unanticipated
problems or legal liabilities.  The combined business' failure to manage growth
effectively would have a material adverse effect on the combined business'
results of operations and its ability to execute its business strategy.

     In addition, the growth experienced by VCA and Pet Practice, and the
corresponding increased need for timely information, have placed significant
demands on VCA's and Pet Practice's existing accounting and management
information systems.  As a result, Pet Practice is in the process of upgrading,
and VCA intends to upgrade, these systems in 1996.  No assurance can be given
that these upgrades will be completed successfully or that the new systems can
be successfully integrated or that the new systems will effectively serve the
combined business' future information requirements.

DEPENDENCE ON ACQUISITIONS FOR FUTURE GROWTH

     VCA's, Pet Practice's and the combined business' respective growth
strategies are dependent principally on their ability to acquire existing
animal hospitals and (in the case of VCA and the combined business) veterinary
diagnostic laboratories.  Successful acquisitions involve a number of factors
which are difficult to control, including the identification of potential
acquisition candidates, the willingness of the owners to sell on reasonable
terms and the satisfactory completion of negotiations.  In addition,
acquisitions may be subject to pre-merger or post-merger review by governmental
authorities for antitrust and other legal compliance.  Adverse regulatory
action could negatively affect VCA, Pet Practice and the combined business'
respective operations through the assessment of fines or penalties against VCA,
Pet Practice and the combined business or the possible requirement of
divestiture of one or more of VCA's, Pet Practice's and the combined business'
operations.

<PAGE>

     There can be no assurance that the combined business will be able to
identify and acquire acceptable acquisition candidates on terms favorable to
the combined business in a timely manner in the future.  Assuming the
availability of capital, VCA's plans include an aggressive acquisition program
involving the acquisition by the combined business of at least 15 to 25
facilities per year.  During the period from January 1, 1996 to June 20, 1996,
VCA acquired (i) Pets' Rx, the owner and operator of 16 animal hospitals, (ii)
three veterinary diagnostic laboratories and (iii) 11 animal hospitals, one of
which was consolidated into an existing facility.  During this same period, Pet
Practice has acquired three veterinary hospitals.  Each of VCA and Pet Practice
continues to evaluate acquisitions and negotiate with several potential
acquisition candidates (although Pet Practice is precluded by the Merger
Agreement from effecting any acquisition while the Merger is pending without
the approval of VCA).  The failure to complete acquisitions and continue
expansion could have a material adverse effect on VCA's, Pet Practice's and the
combined business' financial performance.  As the combined business proceeds
with its acquisition strategy, it will continue to encounter the risks
associated with the integration of acquisitions described above.

LEVERAGE

     VCA, Pet Practice and Pets' Rx have each incurred substantial indebtedness
to finance the acquisition of their respective animal hospitals and (in the
case of VCA) veterinary diagnostic laboratories.  Giving effect to debt
incurred in acquisitions subsequent to March 31, 1996 through June 20, 1996
(excluding the acquisition of Pets' Rx), VCA had at March 31, 1996,
consolidated long-term obligations (including current portion) of approximately
$38.8 million.  Pet Practice had at April 3, 1996 consolidated long-term
obligations (including current portion) of approximately $20.0 million.  At
March 31, 1996, Pets' Rx had consolidated long-term obligations (including
current portion) of $10.4 million.  In addition, on April 17, 1996, VCA issued
subordinated debt in an aggregate principal amount of $84.4 million (the
"Debentures").  At December 31, 1995 and March 31, 1996, VCA's ratio of long-
term debt to total stockholders' equity was 36.3% and 36.4%, respectively.  As
of March 31, 1996, after giving effect to the Transactions and the sale of the
Debentures, the ratio of long-term debt to total stockholders' equity will be
82.8%.  VCA expects to incur additional indebtedness in the future to continue
its acquisition strategy.

<PAGE>

RISKS ASSOCIATED WITH INTANGIBLE ASSETS

     A substantial portion of the assets of VCA, Pet Practice and Pets' Rx
consists of intangible assets, including goodwill and covenants not to compete
relating to the acquisition of animal hospitals and veterinary diagnostic
laboratories.  At March 31, 1996, VCA's balance sheet reflected $85.2 million
of intangible assets of these types, a substantial portion of VCA's $157.0
million in total assets at such date.  At April 3, 1996, Pet Practice's balance
sheet reflected $53.8 million of intangible assets of these types, a
significant portion of Pet Practice's $79.7 million in total assets.  At March
31, 1996, Pets' Rx's balance sheet reflected $9.3 million of intangible assets
of these types prior to pooling adjustments, a significant portion of Pets' 
Rx's $14.6 million in total assets at such date.  VCA expects the aggregate 
amounts of goodwill and other intangible assets on its balance sheet to 
increase in the future in connection with additional acquisitions.  This 
increase will have an adverse impact on earnings as goodwill and other 
intangible assets will be amortized against earnings.  In the event of any sale 
or liquidation of VCA, there can be no assurance that the value of these 
intangible assets will be realized.  In addition, the respective companies 
continually evaluate whether events and circumstances have occurred that 
indicate the remaining balance of intangible assets may not be recoverable.  
When factors indicate that these intangible assets should be evaluated for 
possible impairment, they may be required to reduce the carrying value of 
intangible assets, which could have a material adverse effect on results of 
operations during the periods in which such reduction is recognized.  In 
accordance with this policy, VCA recognized a writedown of goodwill and 
related assets in the amount of $2.3 million in 1993 in connection with three 
of VCA's facilities which were not performing.  There can be no assurance 
that the combined business will not be required to writedown assets further in 
future periods.  In connection with an accounting change related to the pooling 
of interests of Pets' Rx, the combined company will recognize a pretax 
writedown of $2.1 million in each of 1993 and 1995.

GUARANTEED PAYMENTS

     In connection with acquisitions in which the purchase price consists, in
part, of shares of common stock, par value $0.001, of VCA ("VCA Common Stock")
(the "Guarantee Shares"), VCA often guarantees (the "Guarantee Right") that the
value of such stock (the "Measurement Price") two to three years following the
date of the acquisition (the "Guarantee Period") will equal or exceed the value
of the stock on the date of acquisition (the "Issue Price").  In the event the
Measurement Price does not equal or exceed the Issue Price, VCA typically is
obligated either to (i) pay to the seller in cash, notes payable or additional
shares of VCA Common Stock the difference between the Issue Price and the
Measurement Price multiplied by the number of Guarantee Shares then held by the
seller, or (ii) purchase the Guarantee Shares then held by the seller.  Once
the Guarantee Shares are registered for resale under the Act, which
registration VCA covenants to effect generally within six months of issuance of
the Guarantee Shares, the seller's Guarantee Right typically terminates if the
VCA Common Stock trades at 110% to 120% of the Issue Price for five to 15
consecutive days, depending on the terms of the specific acquisition at issue. 
There are 285,444 Guarantee Shares outstanding at March 31, 1996 with Issue
Prices ranging from $11.70 to $17.49 that have not been registered for resale. 
If the value of the VCA Common Stock decreases and is less than an Issue Price
at the end of the respective Guarantee Period for these shares, VCA may be
obligated to compensate these sellers.

<PAGE>

     In connection with the Pet Practice merger, VCA will assume the Guarantee
Rights issued by Pet Practice (which generally operate similarly to the
Guarantee Rights issued by VCA, except that there is no provision for a release
of the Guarantee Right).  Giving effect to the terms of the Merger, the number
of Guarantee Shares issued by Pet Practice is not material to the
capitalization of the combined business.

SEASONALITY AND FLUCTUATING QUARTERLY RESULTS

     A large portion of the businesses of VCA, Pet Practice and Pets' Rx is
seasonal, with operating results varying substantially from quarter to quarter. 
Historically, VCA's revenues have been greater in the second and third quarters
than in the first and fourth quarters.  The demand for VCA's veterinary
services are significantly higher during warmer months because pets spend a
greater amount of time outdoors, where they are more likely to be injured and
are more susceptible to disease and parasites.  In addition, use of veterinary
services may be affected by levels of infestation of fleas, heartworms and
ticks, and the number of daylight hours, as well as general economic
conditions.  A substantial portion of VCA's and the combined business' costs
are fixed and do not vary with the level of demand.  Consequently, net income
for the second and third quarters at individual animal hospitals generally has
been higher than that experienced in the first and fourth quarters.

DEPENDENCE ON KEY MANAGEMENT

     VCA's and the combined business' success will continue to depend to a
significant extent on VCA's executive officers and other key management,
particularly its Chief Executive Officer, Robert L. Antin.  VCA has an
employment contract with Mr. Robert Antin, Mr. Arthur Antin, Chief Operating
Officer of VCA, Mr. Neil Tauber, Senior Vice President of VCA, and Mr. Tomas
Fuller, Chief Financial Officer of VCA, each of which expires in December 1998. 
VCA has no other written employment agreements with its executive officers. 
None of VCA's officers are parties to noncompetition covenants which extend
beyond the term of their employment with VCA.  VCA maintains "key man" life
insurance on Mr. Robert Antin in the amount of $3.0 million, of which VCA is
the sole beneficiary.  VCA does not maintain any insurance on the lives of its
other senior management.  As VCA continues to grow, it will continue to hire,
appoint or otherwise change senior managers and other key executives.  There
can be no assurance that VCA will be able to retain its executive officers and
key personnel or attract additional qualified members to management in the
future.  In addition, the success of certain of VCA's acquisitions may depend
on VCA's ability to retain selling veterinarians of the acquired companies. 
The loss of services of any key manager or selling veterinarian could have a
material adverse effect upon VCA's business.

<PAGE>

JOINT VENTURES

     VCA conducts a portion of its veterinary diagnostic laboratory business
through a joint venture with Vet Research, Inc. ("VRI"), and conducts its pet
food business through a joint venture with Heinz Pet Products, an affiliate of
H.J. Heinz Company.  VCA has an option (the "VCA Option Agreement") in January
1997 to acquire the remaining 49 percent interest in the laboratory joint
venture for $18.6 million in cash plus an additional amount based upon the
earnings of the joint venture to be paid over six years.  Based on current
information available to it, VCA expects to exercise its purchase option in
January 1997.  If for any reason VCA does not exercise the option, VRI has the
option to purchase from VCA its entire 51 percent interest for $3.5 million. 
On the earlier of a change in control of VCA or January 1, 2000, Heinz Pet
Products has the option to purchase all of VCA's interest in the Vet's Choice
joint venture at a purchase price equal to the fair market value of such
interest.  The proposed acquisition of Pet Practice will not result in a change
in control for purposes of the Vet's Choice joint venture.  There can be no
assurance that VCA will not have to sell these joint venture interests.

COMPETITION

     The companion animal health care industry is highly competitive and
subject to continual change in the manner in which services are delivered and
providers are selected.  VCA believes that the primary competitive factors in
connection with animal hospitals are convenient location, recommendation of
friends, reasonable fees, quality of care and convenient hours.  VCA's primary
competitors for its animal hospitals in most markets are individual
practitioners or small, regional multi-clinic practices.  In addition, certain
national companies in the pet care industry, including the operators of super-
stores, are developing multi-regional networks of animal hospitals in markets
which include VCA's animal hospitals.  Among veterinary diagnostic
laboratories, VCA believes that quality, price and the time required to report
results are the major competitive factors.  There are many clinical laboratory
companies which provide a broad range of laboratory testing services in the
same markets serviced by VCA.  In addition, several national companies provide
on-site diagnostic equipment that allows veterinarians to perform their own
laboratory tests.  VCA's major competitors in the premium pet food industry are
Hill's and Iams, both of which have extensive experience in the manufacture of
premium pet food and possess research and development, marketing and financial
resources far greater than that of Vet's Choice.

<PAGE>

GOVERNMENT REGULATION

     The laws of some states prohibit veterinarians from splitting fees with
non-veterinarians and prohibit business corporations from providing veterinary
services through the direct employment of veterinarians.  These laws and their
interpretations vary from state to state and are enforced by the courts and by
regulatory authorities with broad discretion.  Although VCA and Pet Practice
believe their respective operations as currently conducted are in material
compliance with existing applicable laws, there can be no assurance that VCA's
and Pet Practice's existing operational structure will not be successfully
challenged in one or more states as constituting the unlicensed practice of
veterinary medicine.  Such a determination in a state could adversely affect
the operations of VCA and the combined business through the assessment of fines
or penalties against VCA or the combined business or the possible requirement
of divestiture of VCA's operations in the state.  In addition, there can be no
assurance that state legislation or regulations will not change so as to
restrict VCA's or, in the future, the combined business' existing operations or
the expansion of such operations.

ANTI-TAKEOVER EFFECT

     A number of provisions of VCA's Certificate of Incorporation and bylaws
and certain Delaware laws and regulations relating to matters of corporate
governance, certain rights of directors and the issuance of preferred stock
without stockholder approval, may be deemed to have and may have the effect of
making more difficult, and thereby discouraging, a merger, tender offer, proxy
contest or assumption of control and change of incumbent management, even when
stockholders other than VCA's principal stockholders consider such a
transaction to be in their best interest.  In addition, H.J. Heinz Company has
an option to purchase VCA's interest in the Vet's Choice joint venture upon the
occurrence of a change in control (as defined in the joint venture agreement),
which may have the same effect.  Accordingly, stockholders may be deprived of
an opportunity to sell their shares at a substantial premium over the market
price of the shares.

<PAGE>

IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE

     Future sales by existing stockholders could adversely affect the
prevailing market price of the VCA Common Stock.  As of March 31, 1996, VCA had
12,873,129 shares of common stock outstanding, most of which are either freely
tradeable in the public market without restriction or tradeable in accordance
with Rule 144 under the Act.  There are also 159,197 shares which VCA is
obligated to issue in connection with certain acquisitions; 583,333 shares
issuable upon conversion of outstanding preferred stock; 1,505,821 shares of
VCA Common Stock issuable upon exercise of outstanding stock options; 1,607,983
shares of VCA Common Stock issuable upon exercise of outstanding warrants; and
6,635 shares issuable upon conversion of convertible notes.  Shares may also be
issued under price guarantees delivered in connection with acquisitions.  These
shares will be eligible for immediate sale upon issuance.  In addition, as a
result of the consummation of the Pets' Rx transaction, VCA will be
obligated to issue an aggregate of approximately 801,000 shares (subject to
adjustment) and if the Pet Practice transaction is consummated, VCA will be
obligated to issue approximately 3,273,000 shares (assuming the VCA Common Stock
has an average price at that time of $26.375).  In addition, on April 17, 1996, 
VCA issued $84.4 million of 5.25% convertible subordinated debentures which are 
convertible into 2,457,060 shares of VCA Common Stock at a rate of $34.35 per 
share.

POSSIBLE VOLATILITY OF STOCK PRICE

     The market price of the VCA Common Stock could be subject to significant
fluctuations caused by variations in quarterly operating results, litigation
involving VCA, announcements by VCA or its competitors, general conditions in
the companion animal health care industry and other factors.  The stock market
in recent years has experienced extreme price and volume fluctuations that have
often been unrelated or disproportionate to the operating performance of
publicly traded companies.  The broad fluctuations may adversely affect the
market price of the VCA Common Stock.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

                                 MARCH 31, 1996
                                 --------------


1.  GENERAL:
    ------- 

The Company
- - -----------

Pets' Rx, Inc. (the "Company") was incorporated in Delaware on May 28, 1991. The
Company is engaged in the acquisition and operation of veterinary clinics. As of
March 31, 1996, the Company operates 16 clinics in the San Jose and Sacramento,
California, and Las Vegas, Nevada, markets.

The Company has substantial operating and debt service obligations as a result
of the significant acquisition activity. The Company will require additional
capital in 1996 if the merger discussed in Note 3 is not consummated.

Principles of Consolidation
- - ---------------------------

The accompanying consolidated financial statements include the accounts of the
Company and its majority-owned subsidiary and have been prepared in accordance
with generally accepted accounting principles for interim financialinformation.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
All significant intercompany transactions and balances have been eliminated. The
results of operations for the three months ended March 31, 1996 and 1995 are not
necessarily indicative of the results to be expected for the full year. Minority
interest on the accompanying balance sheet represents the initial contribution
of assets to the subsidiary by the minority member increased by the member's
share of income less distributions made.

2.  RECLASSIFICATIONS:
    ----------------- 

Certain prior year amounts have been reclassified to conform to their 1995
classifications.

3.  MERGER AGREEMENT:
    ---------------- 

In February, 1996 the Company entered into a merger agreement (the
"Agreement")with Veterinary Centers of America, Inc. ("VCA"). Under the terms of
the Agreement as amended, which is intended to qualify for pooling-of-interests
accounting, stockholders and rights holders, as defined, are to receive shares
of VCA common stock, par value $0.001 with a market value on June 14,1996 of
approximately $22.4 million.  The stockholders of the Company voted to approve
the merger on June 14, 1996 and the merger is expected to be consummated on June
18, 1996.

4.  SUBSEQUENT EVENT:
    ---------------- 

During the second quarter of 1996, the Company received additional working
capital through the issuance of notes payable to existing shareholders and to
Veterinary Centers of America, Inc. in the amount of $200,000 and $210,000,
respectively.

We conducted our audit in accordance with generally accepted auditing standards

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  ------------------------------------------

                               DECEMBER 31, 1995
                               -----------------



1.   THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES:
     --------------------------------------------------- 

The Company
- - -----------

Pets' Rx, Inc. (the "Company") was incorporated in Delaware on May 28, 1991. The
Company is engaged in the acquisition and operation of veterinary clinics. As of
December 31, 1995, the Company operates 16 clinics in the San Jose and
Sacramento, California, and Las Vegas, Nevada, markets.

The Company has substantial operating and debt service obligations as a result
of the significant acquisition activity (see Note 3). The Company will require
additional capital in 1996 if the merger discussed in Note 11 is not
consummated.

Use of Estimates in the Preparation of Financial Statements
- - -----------------------------------------------------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from the estimates.

Principles of Consolidation
- - ---------------------------

The accompanying consolidated financial statements include the accounts of the
Company and its majority-owned subsidiary. All significant intercompany
transactions and balances have been eliminated. Minority interest on the
accompanying balance sheet represents the initial contribution of assets to the
subsidiary by the minority member increased by the member's share of income less
distributions made.

Revenue Recognition
- - -------------------

Revenues are recognized upon performance of veterinary services or sale of
related veterinary products.

Cash Equivalents
- - ----------------

All highly liquid investments purchased with an original maturity of three
months or less are considered to be cash equivalents.

Inventories
- - -----------

Inventories consist of veterinary supplies, pharmaceuticals, and retail
veterinary products and are stated at the lower of cost, determined using the
first-in, first-out basis, or market.

NOTE 1 - BASIS OF PRESENTATION

The accompanying consolidated financial statements are unaudited, except for the
Consolidated Balance Sheet as of January 3, 1996. The statements have been
prepared in accordance with the rules and regulations of the Securities and
Exchange Commission and should be read in conjunction with the Company's
consolidated financial statements and notes thereto for the year ended January
3, 1996, included in its Annual Report on Form 1O-K, as filed with the
Securities and Exchange Commission. Certain information and note disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations. In the opinion of Company management, the consolidated
financial data for the unaudited interim periods presented include all
adjustments, consisting only of normal recurring adjustments, necessary to
present a fair statement of the results of such interim periods.

Operating results for the thirteen-week period ended April 3, 1996 are not
necessarily indicative of the results that may be expected for a full year or
any portion thereof.

NOTE 2 - DEFINITIVE MERGER AGREEMENT

On March 21, 1996, the Company signed a definitive agreement (the "Merger
Agreement") with Veterinary Centers of America, Inc. ("VCA"), pursuant to which
VCA will acquire all ...... outstanding securities of the Company.

Under the terms of the Merger Agreement, each share of the Company's common
stock will be converted into a fraction of a share of VCA common stock
determined by reference to the average closing price of VCA common stock over
the 20 trading days ending on the third day before the stockholder meetings, at
which the stockholders of VCA and the Company will consider the merger. If the
average price of the VCA common stock ranges from $25 to $30 per share, the
exchange ratio shall be determined by dividing $10 by the average price of VCA
common stock, resulting in a valuation of $10 per share of the Company's Common
Stock throughout the range. If the average closing price of VCA common stock is
less than $24 per share, the exchange ratio will be increased (from 0.395 shares
at $24 per share) by 0.005 for each dollar of such reduction down to $18.50 of
VCA common stock, and if the average price of VCA common stock is more than $31
per share, the exchange ratio shall be reduced (from 0.3350 at $31 per share) by
0.005 for each dollar of such increase, up to $49 per share. No further
adjustment shall be made if the price of VCA common stock

                                    F-18

             (Dollar amounts in thousands, except per share data)
                                  (Unaudited)
 
shall be less than $18.50. In each case, a proportionate reduction or increase,
as the case may be, shall be made if the price of VCA common stock is less than
a round dollar. By way of illustration, at $23 per share of VCA common stock,
the exchange ratio shall be 0.400, resulting in a valuation of $9.20 per share
of the Company's Common Stock. At $32 per share of VCA common stock, the
exchange ratio shall be 0.330, resulting in a valuation of $10.56 per share of
the Company's Common Stock. The merger will be accounted for as a purchase. If
the average price of VCA common stock is greater than $49, the exchange ratio
shall be determined by dividing $12.005 by the average price. Each party has the
right to terminate the definitive agreement if the average price of VCA common
stock is $18.50 or less. The Company expects that the merger will be consummated
in the third quarter of 1996.

Consummation of the merger is subject to certain significant conditions. The
Merger Agreement with VCA may be terminated by either VCA or the Company at any
time prior to the closing (i) if any material condition to the obligations of
the Company or VCA set forth in the Merger Agreement is not substantially
satisfied at the time or times contemplated thereby, (ii) there is a material
breach of any representation, warranty, condition, or agreement contained in the
Merger Agreement (that is not cured within 30 days of the tune that written
notice of such breach is received by the breaching party), (iii) if the merger
shall not have been consummated on or before September 1, 1996, or (iv) upon
their mutual consent.

For all of the foregoing reasons, the merger of VCA and the Company may never be
consummated.

The Company filed a copy of the Merger Agreement with the Securities and
Exchange Commission in its Current Report on Form 8-K dated March 21, 1996.

NOTE 3 - BUSINESS ACQUISITIONS

The Company acquired three clinics during the thirteen weeks ended April 3,
1996.

These acquisitions have been accounted for using the purchase method of
accounting. Accordingly, the purchase price was allocated to assets and
liabilities acquired based upon their estimated fair values at the dates of
acquisition. The results of operations of the acquired companies are included in
the consolidated financial statements from the respective dates of acquisition.

           Net loss                                  (910)
           Net loss per common share                (0.11)

The pro forma results of operations are not necessarily indicative of the actual
results of operations that would have occurred had the acquisitions been made on
January 4, 1996, or the Company's results of operations which may occur in the

flows for the period October 27, 1993 (commencement of operations) to December
29, 1993, the year ended December 28, 1994 and the year ended January 3, 1996 in

NOTE 1 -- ORGANIZATION AND OPERATION:

     The Pet Practice, Inc. (the "Company") was formed to provide companion
animal veterinary care services. The Company's operations commenced on October
27, 1993 with the acquisition of Professional Veterinary Hospitals of America,
Inc. (a Michigan corporation). Since this initial acquisition, the Company has
acquired additional practices (see Note 3) such that as of January 3, 1996, the
Company operates 83 veterinary clinics in 10 states, all in the Eastern half of
the United States.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 Fiscal year:

     The Company's accounting year is a 52-53 week fiscal year which ends on the
Wednesday nearest to December 31.

 Principles of consolidation:

     The consolidated financial statements include the accounts of the Company
and its wholly and beneficially owned subsidiaries ("Subsidiaries"). In response
to certain regulations in certain states in which the Company operates, several
Subsidiaries operate as professional corporations which, in turn, have executed
management agreements with the Company. Through the terms of the management
agreements, the Company has complete unilateral control over the professional
corporations. The management agreements entered into with the professional
corporations substantially restrict the business activities of these
professional corporations and the rights of their shareholders. Under related
agreements, the Company has the option to purchase, or to designate a purchaser
for, the stock of the professional corporations. These professional corporations
are consolidated because the Company (as opposed to affiliates of the Company)
has unilateral and perpetual control over the assets and operations of the
professional corporations and because, notwithstanding the lack of technical
majority ownership, consolidation of the professional corporations is necessary
to present fairly the financial position and results of operations of the
Company due to the existence of a parent-subsidiary relationship by means other
than majority ownership of the professional corporations' voting stock. The
Company has perpetual control over the professional corporations because the
Company does not intend to terminate any of its management agreements with the
professional corporations and, upon termination of any such agreement by the
veterinarian, the Company intends to exercise its option to purchase the stock
of the professional corporation for $100. Fees paid to the Company under these
agreements approximate the operating income, as defined, of the Subsidiaries.
All significant intercompany accounts and transactions have been eliminated.

 Use of estimates in the preparation of financial statements:

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Statement of cash flows:

     For purposes of reporting cash flows, cash and cash equivalents include
cash on hand and short-term investments with original maturities of 90 days or
less.

                                    F-26

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


 Net revenues:
     Net revenues are reported at the estimated amounts to be realized through
payments from customers and are recognized when the services are performed.

 Inventories:

     Inventories consist of pharmaceuticals, retail pet products and other
veterinary care products and are valued at the lower of first-in, first-out
cost, or market.

 Property and equipment:

     Property and equipment are stated at cost less accumulated depreciation and
amortization.  Additions and betterments are capitalized and maintenance and
repairs are charged to current operations.  The cost of assets retired or
otherwise disposed of and the related accumulated depreciation and amortization
are removed from the accounts and the gain or loss on such dispositions is
reflected in current operations.  Depreciation is provided using the straight-
line method.  Estimated useful lives of the assets are:

       Buildings.......................                            20-40 years
       Medical equipment...............                                7 years
       Furniture and fixtures..........                                7 years
       Leasehold improvements..........   Shorter of life of lease or 10 years
       Office equipment................                                5 years
       Vehicles........................                                5 years

 Long-lived and intangible assets:

     Assets and liabilities acquired in connection with business combinations
accounted for under the purchase method are recorded at their respective fair
values.  Deferred taxes have been recorded to the extent of differences between
the fair value of the tax basis of the assets acquired and liabilities assumed.
The excess of the purchase price over the fair value of the net assets acquired
is amortized on a straight-line basis over 40 years.  Other intangible assets
include client lists, assembled work force, and non-competition agreements,
which are amortized on a straight-line basis over periods ranging from three to
six years.

     The Company adopted Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" (SFAS No. 121), effective December 29, 1994.  The carrying value
of long-lived assets and certain identifiable intangible assets will be
evaluated whenever changes in circumstances indicate the carrying amount of such
assets may not be recoverable.  In performing such review for recoverability,
the Company compares the expected future cash flows to the carrying value of
long-lived assets and identifiable intangibles.  If the expected undiscounted
future cash flows are less than the carrying amount of such assets, the Company
recognizes an impairment loss for the difference between the carrying amount of
the assets and their estimated fair value.  If an asset being tested for
recoverability was acquired in a business combination accounted for using the
purchase method, the excess of cost over fair value of net assets that arose in
that transaction is allocated to the assets being tested for recoverability on a
pro rata basis using the relative fair values of the long-lived assets and
identifiable intangibles acquired at the acquisition date.  In estimating future
cash flows for determining whether an asset is impaired, and if expected future
cash flows are used in measuring assets that are impaired, assets are grouped by
operating unit.

                                    F-27

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)


     In addition, the carrying value of the excess of cost over fair value of
net assets acquired is subject to a separate evaluation by estimating the
expected future undiscounted net cash flows from operating activities. If these
estimated net cash flows are less than the carrying amount of the excess of cost
over fair value of net assets acquired, the Company recognizes an impairment
loss in an amount necessary to write down the excess of cost over fair value of
net assets acquired to fair value, as determined from expected future cash 
flows.

 Income taxes:

     The Company has applied the asset and liability approach of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes, for
financial accounting and reporting purposes.  The Company accounts for certain
items of income and expense in different time periods for financial reporting
and income tax purposes.  Provisions for deferred income taxes are made in
recognition of such temporary differences, where applicable.  A valuation
allowance is established against deferred tax assets unless the Company believes
it more likely than not that the benefit will be realized.

 Net loss per common share:

     Net loss per common share for the period ended December 29, 1993 and the
year ended December 28, 1994 has been computed by dividing the net loss
applicable to common stock by the number of shares of common stock outstanding
at August 4, 1995 (the date of consummation of the Company's initial public
offering of its common stock), as all shares issued prior to that date were
issued at prices significantly below the offering price in the Company's initial
public offering of its common stock.

     Net loss per common share for the year ended January 3, 1996 has been
computed by dividing the net loss applicable to common stock by the weighted
average number of common shares outstanding during the year.  For purposes of
computing such weighted average, the number of shares of common stock
outstanding at August 4, 1995 was treated as outstanding for the entire period
from December 29, 1994 to August 4, 1995.

NOTE 3 -- BUSINESS ACQUISITIONS:

     On October 27, 1993, the Company acquired all of the issued and outstanding
common stock of Professional Veterinary Hospitals of America, Inc. (a Michigan
corporation).  During 1994, the Company purchased all of the issued and
outstanding common stock of three practices and certain assets of an additional
10 practices.  During 1995, the Company purchased all of the issued and
outstanding common stock of three practices and certain assets of an additional
38 practices.

     The acquisitions have been accounted for using the purchase method of
accounting.  Accordingly, the purchase price was allocated to assets and
liabilities acquired based upon their estimated fair values at the dates of
acquisition.  The results of operations of the acquired companies are included
in the consolidated financial statements from the respective dates of
acquisition.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)


     Notes and mortgages payable arose principally from acquisitions and include
certain amounts due to related parties.  Certain of the Company's acquisition
notes payable are secured by the assets of the veterinary practice acquired.

     The borrowings under lines of credit with a bank at December 28, 1994
represented borrowings pursuant to a $13,000 credit facility and were made at
the bank's prime rate.  Such notes were secured by the guarantee of a
stockholder.  In February 1995, the Company entered into a $5,000 line of credit
facility with another financial institution.  Borrowings under this facility
were made at market interest rates and were secured by a guarantee of a
stockholder as well as certain of the Company's operating subsidiaries.  Both of
these credit facilities with banks were terminated effective with the Company's
initial public offering.

     The book value of notes and long-term debt approximates their fair value.

NOTE 6 -- INCOME TAXES:

     Due to the Company's operating losses, no provision for federal income
taxes was recorded during any period. A provision for current state income taxes
was recorded during the years ended December 28, 1994 and January 3, 1996.

     At January 3, 1996, the Company had net operating loss carryforwards for
federal income tax purposes of approximately $12,200 (the estimated tax benefit
of which is approximately $4,138).  Their use is limited to future taxable
earnings of the Company and, as specified in the Internal Revenue Code, use of
certain of the net operating loss carryforwards is limited as they were acquired
by the Company in a purchase of the stock of another company.  The carryforwards
expire in varying amounts through 2010.  A valuation reserve has been
established against the benefit of the net operating loss carryforwards.

</TABLE>

     Certain of the leases contain renewal options and escalation clauses which
require payments of additional rent to the extent of increases in related
operating costs.  Included in future rental commitments are payments totaling
$10,178 which will be made to related parties.  Six of these leases are with
partnerships in which a director of the Company is a partner, and these leases
expire at various dates from 1997 through 2003, although the Company has renewal
options.  Rent expense was $118 for the period October 27 to December 29, 1993,
$971 for the year ended December 28, 1994, and $1,865 for the year ended January
3, 1996.

 Contingent payments related to business acquisitions:

     In connection with certain acquisitions (see Note 3), the Company has
entered into contractual arrangements whereby additional shares of the Company's
common stock and cash may be issued to former owners of acquired practices upon
attainment of specified financial and non-financial criteria over periods of
three to five years as set forth in the respective agreements. The number of
shares of common stock and cash to be issued can not be determined until the
earnout periods expire and the attainment of criteria is established. If such
criteria are attained, but not exceeded, the Company will be obligated to make
cash payments of approximately $2,881 and issue approximately 90,000 shares of
common stock over the next five years.

     A lesser amount of cash would be paid and a lesser number of shares of
common stock would be issuable under certain acquisition agreements if the
financial criteria are not met and a greater amount of cash would be paid and a
greater number of shares of common stock would be issuable under certain
acquisition agreements if the financial criteria are exceeded. For example, if
the financial criteria with respect to each of the acquisitions were to be
exceeded by 20%, the Company would be obligated to make cash payments of $3,167
and issue approximately 109,000 shares of common stock over the next five years.
Since, by the terms of the related agreements, these payments are considered
contingent consideration for the acquired business, amounts payable pursuant to
these provisions, if earned, will be recorded as additional purchase price in
the period the criteria are attained.

                                    F-32

     In addition, in certain circumstances, the Company is required to issue
additional shares of common stock if, on the second anniversary of the
acquisition closing, the market price of the common stock falls below specified
levels ranging from $10.00 to $16.00 per share.  Based on the market price of
the common stock at January 3, 1996, an aggregate of approximately 19,000 shares
would be issuable.  Additionally, the number of shares of common stock delivered
in connection with one acquisition as part of the purchase price was subject to
adjustment, such that the value of such shares was equal to $320 as of the date
of the Company's initial public offering. The Company issued an additional 1,334
shares of common stock in connection with such acquisition.  Additional shares
issued were recorded as an adjustment to the previously issued consideration.

     In connection with two acquisitions, the Company entered into arrangements
with the former owners, who are now employees, that provided for amounts to be
payable upon attainment of a number of specified financial and non-financial
criteria.  Since, by the terms of the related agreements these payments are
considered compensatory, amounts payable pursuant to these provisions, if
earned, are recorded as compensation expense.  In June 1995, the Company
renegotiated these arrangements to eliminate future payments based on
performance criteria in exchange for non-interest bearing notes payable by the
Company.  The settlement of these arrangements resulted in one-time, non-cash
charges to general and administrative expenses of approximately $383 and $705 in
the years ended December 28, 1994 and January 3, 1996, respectively.

     One arrangement for contingent compensation payments remains in place,
which calls for estimated aggregate payments of approximately $260 over the next
five years if specified criteria are attained.

NOTE 9 -- EMPLOYEE BENEFITS:

 401(k) Plan:

     Beginning in April 1994, the Company sponsored a 401(k) plan for employees
with more than one year of service.  Contributions to the plan totaled $10 for
the period from inception of the Plan to December 28, 1994, and $14 for the year
ended January 3, 1996.


 1994 Stock Option Plan:

     The Company sponsors a stock option plan for key employees and directors.
There are available for options under the Plan a total of 400,000 shares of
common stock.  As of January 3, 1996, total options to purchase 100,250 shares
have been granted.  Such options are exercisable at prices ranging between $4.00
and $15.00 per share over the next 10 years.  All options are subject to a five-
year vesting period.  At January 3, 1996, 2,700 options were vested.  No options
have been exercised.

grant date, therefore no compensation expense is recorded relative to the plan.

NOTE 10 -- STOCKHOLDERS' EQUITY (DEFICIT)

     On August 4, 1995, the Company consummated its initial public offering of
4,300,000 shares of common stock at $15.00 per share.  The net proceeds of the
offering of approximately $56,600 were used (i) to repay $12,391 principal
amount of related-party debt, together with accrued interest; (ii) to redeem
$800 of the Company's Redeemable Preferred Stock, together with accrued
dividends; (iii) to repay approximately $13,000 borrowed from United States

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 - ACCOUNTING POLICIES:

  Basis of presentation:

     Professional Veterinary Hospitals of America, Inc. ("PVH" or the "Company")
provides on-site veterinary services and related activities in southeastern 
Michigan.

     PVH's accounting year was a 52-53 week fiscal year which ended on the last 
Wednesday in January. The results of operations and changes in stockholders' 
equity (deficit) and cash flows presented herein are for the year ended January 
27, 1993 and the period from January 28, 1993 through October 26, 1993 (see
Note 9).

  Net revenues:

     Net revenues are reported at the estimated amounts to be realized through 
payments from customers and are recognized when the service is performed.

  Inventory:

     Inventory consists of pharmaceuticals, retail pet products and other 
veterinary care products and is valued at lower of market or cost determined on 
a first-in, first-out basis.

  Property and equipment:

     Property and equipment are stated at cost less accumulated depreciation. 
Additions and improvements to property and equipment are capitalized and 
maintenance and repairs are charged to current operations. Adjustments of the 
assets and the related accumulated depreciation accounts are made for 
retirement and disposal of property and equipment with the resulting gain or 
loss included in the results of operations.

     Depreciation is provided substantially using the straight-line method. 
Estimated useful lives of the assets are:

<TABLE>
<S>                                       <C> 
     Building and building improvements.. Shorter of the life of the lease or 31.5 years
     Leasehold improvements.............. Shorter of the life of the lease or 10 years
     Furniture and equipment............. 5 to 10 years
</TABLE> 

  Goodwill:

     The excess of cost over acquired net assets (goodwill) is being amortized 
on a straight-line basis over its estimated useful life of 40 years.

  Cash equivalents:

     For purposes of the statement of cash flows, all highly liquid investments
with a maturity of three months or less are considered cash equivalents.

  Income taxes:

     The Company has adopted Statement of Financial Accounting Standards No. 
109, "Accounting for Income Taxes" (FAS 109). The asset and liability approach 
requires the recognition of deferred tax liabilities and assets for the expected
future tax consequences of temporary differences between the carrying amounts 
and the tax bases of assets and liabilities.

                                    F-40

              PROFESSIONAL VETERINARY HOSPITALS OF AMERICA, INC.

                  NOTES TO FINANCIAL STATEMENTS - (Continued)

NOTE 2 - LEASES:

   PVH's facility leases are classified as operating leases and expire on 
various dates through January 21, 2002. Most leases contain renewal options. 
Additionally, PVH leases certain office and medical equipment under leases 
classified as capital with an initial or remaining term in excess of one year. 
Amounts charged to operations for rental expense were $606,960 and $424,328 for 
the fiscal year ended January 27, 1993 and the period ended October 26, 1993, 
respectively.

NOTE 3 - FINANCING ARRANGEMENT:

   On January 29, 1992, the Company entered into a sale and leaseback agreement 
in connection with two of its hospital facilities including land, building, 
furniture and equipment with Mack/Inkster Properties Limited Partnership, a 
Michigan limited partnership. Under the sale agreement, the Company sold the 
facilities for $600,000. In addition, the Company entered into an agreement to 
leaseback the facilities for a ten-year period with varying monthly rental 
charges of $5,800 to $15,000 over the life of the lease. The Company made lease 
payments totaling $69,600 and $52,200 during the year ended January 27, 1993 and
during the period from January 28 to October 26, 1993, respectively. Because the
agreement provides the Company with an option to repurchase the assets, the 
sale-leaseback is accounted for as a financing from the partnership. The net 
book value of the facilities is amortized over the life of the lease agreement.

   Concurrent with the purchase of the Company by The Pet Practice, Inc. (see 
Note 9), the Company purchased all of the property owned by Mack/Inkster 
Properties Limited Partnership for $700,000.

NOTE 4 - SUBORDINATED NOTES:

   On May 14, 1991, PVH issued subordinated notes with a face value of 
$1,400,000 and warrants to purchase 250,000 shares of Class A common stock to 
stockholders of the Company with interest at 11% payable in varying amounts 
through July 1, 1994. At October 26, 1993, $1,310,000 of the notes were 
outstanding.

   From July 1, 1994 through December 31, 1994, the holders of the warrants may 
purchase up to 250,000 shares of Class A common stock at $2.50 per share or 
require PVH to redeem each warrant for $3.00. If PVH defaults on principal 
payments under the subordinated notes, additional warrants may be issued.

   The Company provides for the estimated cost associated with redemption of the
warrants by recording charges to interest expense. Such charges were $452,000 
for the year ended January 27, 1993, and $196,000 for the period ended October 
26, 1993.

   Concurrent with the purchase of the Company by The Pet Practice, Inc. (see 
Note 9), the Company repaid the subordinated debt and related accrued interest 
and repurchased the warrants for a total of $1,600,000.

NOTE 5 - LONG-TERM DEBT:

   Other long-term debt arrangements consisted of the following at
    October 26, 1993:

   Note payable, bank, with monthly payments of $14,919 plus
    interest at 1% above prime due through October 1, 1994. This
    loan was repaid concurrent with the transaction described in

                  NOTES TO FINANCIAL STATEMENTS - (Continued)

NOTE 6 - RELATED PARTY TRANSACTIONS:

   PVH Property Management Co., a partnership owned by two of the stockholders 
of PVH, leases office and clinic space to PVH. During the periods ended January 
27, 1993 and October 26, 1993, PVH paid $231,600 and $173,700, respectively, in 
lease payments to PVH Property Management Company.

Two of the stockholders of PVH are partners in the Mack/Inkster Properties 
Limited Partnership (see Note 3).

NOTE 7 - INCOME TAXES:

   No current or deferred provision for federal income taxes has been recorded
by the Company for the year ended January 27, 1993 or for the period January 28
to October 26, 1993 due to net operating losses incurred by the Company during
these periods. At October 26, 1993, PVH had net operating loss carryforwards of
approximately $3,957,000, which may be used to reduce future taxable income and
expires beginning in 1997. Their use is limited to future taxable earnings of
the Company and, as specified in the Internal Revenue Code, certain ownership
changes would result in limitations on the Company's ability to utilize its net
operating loss carryforwards.

   The provision for income taxes differs from the amount of income tax 
determined by applying statutory tax rates to pretax income primarily due to the
net operating losses for which no benefit is recorded.

NOTE 8 - COMMON STOCK:

   Class B common stock is entitled to such votes and dividends that it would be
entitled to had it been converted into Class A common stock. Upon liquidation, 
Class B common stock ranks senior to the rights of Class A common stock. In 
addition, Class B common stock is convertible, only in its entirety, to Class A 
common stock on a 100 to 1 basis.

NOTE 9 - SUBSEQUENT EVENT:

   On October 26, 1993, The Pet Practice, Inc., a Delaware corporation, acquired
100% of the stock of the Company.

                       UNAUDITED PRO FORMA FINANCIAL DATA

VETERINARY CENTERS OF AMERICA, INC. AND SUBSIDIARIES

         The following unaudited pro forma financial data and explanatory notes
give effect to all acquisitions (36 animal hospitals and nine veterinary
diagnostic laboratories) completed by VCA during 1995 and 1996 (through June 7,
1996) (the "VCA Acquired Companies"), VCA's issuance on April 17, 1996 of the
Debentures and the pending acquisition of four animal hospitals (the "Pending
VCA Acquisitions").

         The unaudited pro forma financial data have been prepared utilizing
the historical consolidated financial statements of VCA and the historical
financial statements of the VCA Acquired Companies and the Pending VCA
Acquisitions.  The acquisitions have been accounted for under purchase
accounting except for the acquisition of two animal hospitals which have been
accounted for as a pooling of interests.  The unaudited pro forma financial
data are based on the estimates and assumptions set forth in the notes thereto.

         The unaudited pro forma condensed consolidated statements of
operations for VCA represent the historical results of operations of VCA for
the year ended December 31, 1995 and the three months ended March 31, 1996
adjusted to reflect the acquisitions of the VCA Acquired Companies and the
Pending VCA Acquisitions as if they had occurred at the beginning of the
period.  The unaudited pro forma condensed consolidated balance sheet
represents the balance sheet of VCA at March 31, 1996 adjusted to reflect the
issuance of the Debentures and the acquisitions of the VCA Acquired Companies
acquired after March 31, 1996 and the Pending VCA Acquisitions as if such
acquisitions had occurred on March 31, 1996.

          Unaudited pro forma financial data are provided for illustrative
purposes only and are not necessarily indicative of the results of operations
or financial position that would have occurred if the issuance of the
Debentures and the acquisitions of the VCA Acquired Companies and the Pending
VCA Acquisitions had been consummated at the beginning of the period presented
and March 31, 1996 respectively, nor are they necessarily indicative of future
operating results or financial position.

give effect to all acquisitions (41 animal hospitals during 1995 and through
June 7, 1996) completed by Pet Practice (collectively, the "Pet Practice
Acquired Companies").  The unaudited pro forma financial data should be read in
conjunction with Pet Practice's historical consolidated financial statements
and notes thereto appearing elsewhere in this Joint Proxy Statement/Prospectus.

      The unaudited pro forma financial data have been prepared utilizing the
historical financial statements of Pet Practice and the historical financial
statements of the Pet Practice Acquired Companies.  The unaudited pro forma
financial data are based on the estimates and assumptions set forth in the
notes to the unaudited pro forma financial data.

      The unaudited pro forma condensed consolidated statements of operations
represent the historical results of operations of Pet Practice for the period
ended January 3, 1996 and the thirteen weeks ended April 3, 1996 adjusted to
reflect acquisitions of the Pet Practice Acquired Companies as if they had
occurred at the beginning of the periods presented.  Each of the acquisitions
has been accounted for as a purchase.

      The unaudited pro forma financial data are provided for illustrative
purposes only and are not necessarily indicative of the results of operations
or financial position that would have occurred if the acquisitions of the Pet
Practice Acquired Companies had been consummated at the beginning of the
periods presented, nor are they necessarily indicative of future operating

     NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

 (1)  Represents the reduction of amortization expense due to the conforming 
      reclassification of medical records to goodwill and the reduced goodwill
      amortization due to the 1993 conforming writedown of assets.

 (2)  To reflect the writedown of assets related to conforming the Pets' Rx 
      method for evaluation the impairment of long lived assets to VCA's 
      method.  VCA uses an estimate of the related facility's undiscounted net 
      income over the remaining life of the goodwill and other intangibles in 
      measuring whether the goodwill is recoverable.

 (3)  Reflects the issuance of approximately 801,000 shares of VCA Common Stock
      for all of the outstanding securities of Pets' Rx.

 (4)  Represents the exchange of the redeemable convertible preferred stock as
      part of the Merger.


 VCA, PET PRACTICE AND PETS' RX

      The following unaudited pro forma financial data and explanatory notes
 give effect to the combination of VCA (as adjusted for the acquisitions of the
 VCA Acquired Companies, the VCA Pending Acquisitions and the issuance of the
 Debentures), Pet Practice (as adjusted for the acquisitions of the Pet Practice
 Acquired Companies) and Pets' Rx.  The combination with Pet Practice is
 reflected as a purchase and the combination with Pets' Rx is reflected as a
 pooling of interests.  The unaudited pro forma combined financial data should
 be read in conjunction with the historical Consolidated Financial Statements
 and Notes thereto of VCA, Pet Practice and Pets' Rx and the unaudited pro forma
 financial data of VCA and Pet Practice which are included elsewhere in this
 Form 8-K.

      This unaudited pro forma data have been prepared utilizing VCA's unaudited
 pro forma financial data, Pet Practice's financial data and the historical
 financial statements of Pets' Rx.  The unaudited pro forma financial data are
 based on the estimates and assumptions set forth in the notes to the unaudited
 pro forma financial data.

      The unaudited pro forma condensed combined statements of operations
 reflecting the combination of VCA, Pet Practice and Pets' Rx represent the
 historical results of operations of VCA for the three years ended December 31,
 1995 and the three months ended March 31, 1996 adjusted to reflect (i) the
 acquisitions of the VCA Acquired Companies, the VCA Pending Acquisitions and
 the Merger with Pet Practice as if such transactions had occurred on January 1,
 1995, and (ii) the acquisition of Pets' Rx as if it had occurred on January 1,
 1993.  The unaudited pro forma condensed combined balance sheet was prepared to
 reflect certain of the transactions as if they had occurred at March 31, 1996.

      Unaudited pro forma financial data are provided for illustrative purposes
 only and are not necessarily indicative of the results of operations or
 financial position that would have occurred if the Merger with Pet Practice and
 the merger with Pets' Rx had been consummated at the beginning of the period,
 nor are they necessarily indicative of future operating results or financial
 position.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Veterinary Centers of America, Inc.:

     We have audited the accompanying supplemental combined balance sheets of
Veterinary Centers of America, Inc. (a Delaware corporation), and subsidiaries,
as of December 31, 1995 and 1994, and the related supplemental combined
statements of operations, changes in stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1995 and the balance
sheet of Pets' Rx, Inc. as of December 31, 1995, and the related statements of
operations, changes in stockholders' equity and cash flows for the year then
ended included in the supplemental combined financial statements of Veterinary
Centers of America, Inc.  The supplemental combined historical statements give
retroactive effect to the merger with Pets' Rx, Inc., on June 19, 1996, which
subsequently will be accounted for as a pooling of interests as described in
Note 1.  These supplemental financial statements are the responsibility of the
Companies' management.  Our responsibility is to express an opinion on these
supplemental financial statements based on our audits.

     We did not audit the 1994 and 1993 financial statements of Pets' Rx, Inc.,
included in the supplemental combined financial statements of Veterinary Centers
of America, Inc., which statements reflect total assets and revenues
constituting 25 percent and 19 percent, respectively, in 1994 and 19 percent of
revenue in 1993, of the related supplemental combined totals.  These statements
were audited by other auditors whose reports thereon has been furnished to us,
and our opinion expressed herein, insofar as it relates to the amounts included
for Pets' Rx, Inc., in 1994 and 1993 is based solely upon the reports of the
other auditors.

     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the reports of the other auditors provide a
reasonable basis for our opinion.

     In our opinion, based upon our audits and the reports of the other
auditors, the supplemental combined financial statements referred to above
present fairly, in all material respects, the combined financial position of
Veterinary Centers of America, Inc. and Pets' Rx, Inc. as of December 31, 1995
and 1994, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1995, after giving retroactive
effect to the merger with Pets' Rx, Inc. as described in Note 1, in conformity
with generally accepted accounting principles.

1.  BASIS OF PRESENTATION, BUSINESS AND ORGANIZATION

The Merger

 In June 1996, Veterinary Centers of America, Inc. ("VCA" or the "Company")
merged with Pets' Rx, Inc. (Pets' Rx), in a transaction to be accounted for as a
pooling of interests (the "Merger").  On or about August 15, 1996, VCA will
restate its historical financial statements to reflect the pooling of interests
transaction.  Those restated financials will resemble these supplemental
combined consolidated financial statements in all material aspects.  These
supplemental financial statements are presented to provide the reader with an
understanding of the combined historical results of VCA.


 Pursuant to the Merger, each share of Pets' Rx common stock was converted into
 .08617 shares of VCA common stock.  In aggregate, 6,323,294 million shares of
Pets' Rx common stock were converted into 544,880 shares of VCA common stock.
Each share of Pets' Rx redeemable convertible preferred stock outstanding
immediately prior to the merger was converted in the aggregate into 118,329 
shares of VCA common stock.  Each share of convertible preferred stock 
outstanding immediately prior to the Merger was converted in the aggregate 
into 137,872 shares of VCA common stock.  Previously reported financial 
information for VCA and Pets' Rx for each of the three years in the period 
ended December 31, 1995, is shown in the table below.  To conform to 
consistent methods of accounting, adjustments of historical data were made.
Among these were the adjustments related to the allocation of intangible assets
in connection with purchase transactions and the related amortization and the
writedown of intangible assets resulting from conforming to VCA's method of
analyzing the realization of goodwill utilizing the undiscounted net income
method.

Veterinary Centers of America, Inc. Formation

 Veterinary Centers of America, Inc. ("VCA" or the "Company"), a Delaware
corporation, was founded in 1986 and is a leading companion animal health care
company.  The Company operates one of the largest networks of free-standing,
full service animal hospitals in the country and one of the largest networks of
veterinary-exclusive diagnostic laboratories in the nation.  The Company also
markets both a life-stage and a therapeutic line of premium pet foods through
Vet's Choice, a joint venture with Heinz Pet Products, an affiliate of H.J.
Heinz Company.

 At June 19, 1996, the Company owned 80 animal hospitals, 19 of which were
located in Northern California, 18 in Southern California, eight in
Pennsylvania, six in Massachusetts, five in Nevada, four in Maryland, three in
each of Alaska, Florida and New Mexico, two in each of Colorado, Utah and
Virginia, and one in each of Arizona, Georgia, Hawaii, Illinois and Delaware.
The Company's animal hospitals provide primary care, diagnostic, surgical and
boarding services for animals.

              NOTES TO SUPPLEMENTAL COMBINED FINANCIAL STATEMENTS

         (Information with respect to the unaudited three months ended
    March 31, 1996 and 1995 is not covered by report of independent public 
                                  accountants)

 In March 1994, the Company expanded its presence in the laboratory business
with the acquisition of a 70 percent interest in Professional Animal Laboratory
("PAL").  During 1995, the Company further expanded its laboratory business with
the acquisition of Cenvet, Inc. ("Cenvet") and its subsequent contribution to
Vet Research Laboratories, LLC. ("Vet Research").  Also in 1995, the Company
acquired four other veterinary diagnostic laboratories, as well as the remaining
30 percent interest in PAL.  The Company's laboratories serve over 8,000 animal
hospitals located in 40 states.

 In January 1993, the Company formed a joint venture, Vet's Choice, to develop,
manufacture, market and distribute new pet products and services.  The joint
venture was in the development stage during all of 1993 and consequently
generated no revenues or gross profit in 1993 (Note 4).  The joint venture
distributes two lines of premium pet food, Select Balance, a life-stage diet and
Select Care, a therapeutic line.  Select Balance is sold to veterinary hospitals
and clinics, as well as pet stores.  Select Care is sold  only to veterinary
hospitals.

Pets' Rx Formation

 Pets' Rx was incorporated in Delaware on May 28, 1991.  The Company is engaged
in the acquisition and operation of veterinary clinics.  As of December 31,
1995, the Company operates 16 clinics in the San Jose and Sacramento,
California, and Las Vegas, Nevada, markets.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a.  Principles of Consolidation

 The supplemental combined financial statements include the financial position
and results of operations of VCA and all of its subsidiaries combined with the
financial position and results of operations of Pets' Rx and all of its
subsidiaries.  As previously discussed, these supplemental combined financial
statements reflect how VCA's consolidated financial statements will look
following the June 19, 1996 restatement for the merger with Pets' Rx.

b.  Interim Accounting Policy

 The accompanying unaudited supplemental combined financial statements have not
been audited by independent public accountants, but in the opinion of VCA and
Pets' Rx management, such unaudited statements include all adjustments
(consisting only of normal recurring accruals) necessary for a fair presentation
of the combined financial positions of VCA and Pets' Rx as of March 31, 1996 and
the results of their operations and cash flows for the three months ended March
31, 1995 and 1996.  Although the management of VCA and Pets' Rx believes that
the disclosures in these supplemental combined financial statements are adequate
to make the information presented not misleading, certain information normally
included in financial statements prepared in accordance with generally accepted
accounting principles has been condensed or omitted pursuant to the rules and
regulations of the Securities and Exchange Commission.  The results of
operations for the three months ended March 31, 1995 and 1996 are not
necessarily indicative of the results to be expected for the full year.

c.  Cash Equivalents

 For purposes of the balance sheets and statements of cash flows, the Company
considers only highly liquid investments to be cash equivalents.  Of its cash on
hand at December 31, 1995 and 1994, $1,907,000 and $2,982,000, respectively, was
restricted for use in the conduct of the Vet's Choice joint venture.

d.  Inventory

 Inventory is valued at the lower of cost or market using the first-in, first-
out method.

    March 31, 1996 and 1995 is not covered by report of independent public 
                                  accountants)

e.  Property, Plant and Equipment

 Property, plant and equipment is recorded at cost.  Capitalized equipment
leases are recorded at the lower of the present value of the minimum lease
payments or the fair value of the equipment at the beginning of the lease term.

 Depreciation is recorded using the straight-line method over the estimated
useful lives of property and equipment (principally five to seven years) and
capitalized equipment leases (principally five years).  Leasehold improvements
are amortized over the lives of the leases (principally 10 years).  Costs of
normal repairs and maintenance are expensed as incurred.

Property, plant and equipment consisted of:

</TABLE>

 Accumulated depreciation on equipment held under capital leases amounted to
$303,000 and $170,000 at December 31, 1995 and 1994, respectively.

f.  Goodwill and Other Intangible Assets

 Goodwill relating to acquisitions represents the purchase price paid and
liabilities incurred in excess of the fair market value of net assets acquired.
Goodwill is amortized over the expected period to be benefited, not exceeding 40
years, on a straight-line basis.

 Subsequent to its acquisitions, the Company continually evaluates whether
events and circumstances have occurred that indicate the remaining estimated
useful life of goodwill may warrant revision or that the remaining balance of
goodwill may not be recoverable.  When factors indicate that goodwill should be
evaluated for possible impairment, the Company uses an estimate of the related
facility's undiscounted net income over the remaining life of the goodwill in
measuring whether the goodwill is recoverable (Note 13).

 Other intangible assets principally include covenants not to compete.  The
value assigned to the covenants not to compete is amortized on a straight-line
basis over the term of the agreements (principally 5 to 10 years).

 Accumulated amortization of goodwill and covenants not to compete and other at
December 31, 1995 is $3,563,000 and $2,986,000, respectively.  Accumulated
amortization of goodwill and covenants not to compete and other at December 31,
1994 is $3,792,000 and $1,259,000, respectively.

 In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed Of."  The Statement
requires that long-lived assets and certain identifiable intangibles held and
used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable.  The Statement was adopted by the Company

                                  accountants)

on January 1, 1996.  The Company does not expect implementation of this
statement to have a material effect on its financial position or its results of
operations.

g.  Investments

 Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards No. 115, "Accounting For Certain Investments in Debt and
Equity Securities," which establishes standards of financial accounting and
reporting for investments in equity securities that have readily determinable
fair values and for all investments in debt securities.  The adoption of this
Statement did not  have a material effect on the financial position or results
of operations of the Company.

h.  Accounting Change

 Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting For Income Taxes," which requires
recognition of deferred tax liabilities and assets for the expected future tax
consequences of events that have been included in the financial statements or
tax returns.  Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse (Note 11).

 The cumulative effect of this accounting change, which resulted in recognizing
previously unrecognized tax benefits for years prior to January 1, 1993,
decreased the net loss for 1993 by $221,000.

i.  Reclassifications

 Certain 1994 balances have been reclassified to conform with the 1995 financial
statement presentation.

3.  ACQUISITIONS AND DISPOSITIONS

 During 1996, through June 19, 1996, the Company purchased 11 veterinary
hospitals and three veterinary diagnostic laboratories in separate transactions.
In connection with the acquisitions which were accounted for as a purchase, the
aggregate consideration (including acquisition costs) was $28,718,000 consisting
of $13,614,000 in cash, $8,066,000 in long-term obligations, 242,926 shares of
VCA common stock with a value of $3,868,000 and the assumption of liabilities
totalling $3,170,000.  In connection with the two acquisitions which were
treated as a pooling of interests, VCA issued 151,010 shares of VCA common
stock.  Additionally, on June 19, 1996 the Company consummated a merger with
Pets' Rx for 801,081 shares of VCA common stock.  The merger with Pets' Rx will
be accounted for as a pooling of interests.

 During 1995, the Company purchased 25 animal hospitals for an aggregate
consideration (including acquisition costs) of $29,019,000, consisting of
$6,436,000 in cash, $10,859,000 in debt, 836,576 shares of common stock of the
Company, with a value of $9,780,000, and the assumption of liabilities totaling
$1,944,000.  In addition, the Company paid $250,000 to acquire an option to
purchase the land and building of two of the hospitals.

 Also during 1995, the Company purchased substantially all of the assets of
Cenvet, a full-service veterinary diagnostic laboratory, four other veterinary
diagnostic laboratories and the remaining 30 percent interest in PAL, for an
aggregate consideration of $13,986,000, including acquisition costs, consisting
of $2,671,000 in cash, $8,633,000 in long-term obligations, 238,712 shares of
VCA common stock, with a value of $2,200,000 and the assumption of liabilities
totaling $482,000.

 On March 20,1995, the Company and Vet Research, Inc., ("VRI"), formed Vet
Research Laboratories, LLC ("Vet Research").  In connection with the formation
of Vet Research, VRI contributed all of the assets and certain of the
liabilities of VRI's full-service veterinary diagnostic laboratory located in
Farmingdale, New York.  The Company contributed substantially all of the assets
and certain of the liabilities of Cenvet for a 51 percent controlling interest
in the joint venture (Note 4).

 In connection with the formation of Vet Research, the Company issued warrants
to purchase 363,636 shares of the common stock of the Company at $11.00 per
share.  The warrants were purchased at $0.001 per warrant and are exercisable
until the fifth day

                                    F-70

following the last day upon which the Company is permitted to close the purchase
of VRI's interest in Vet Research  pursuant to the VCA Option Agreement.

 In 1994, VCA purchased four veterinary hospitals for a total consideration
(including acquisition costs) of $5,754,000 consisting of $1,329,000 in cash,
$3,663,000 in non-recourse promissory notes payable, 91,996 shares of VCA common
stock with a value of $680,000, and the assumption of liabilities totaling
$82,000.  In addition, the Company paid $60,000 to acquire an option to purchase
the land and building of one of the hospitals.

 In 1994, the Company acquired substantially all of the assets and assumed
certain of the liabilities of PAL, a full-service veterinary laboratory, located
in Irvine, California.  In connection with the purchase, the Company also
acquired from a principal shareholder of PAL, the real property and building
occupied by the business of PAL.  The net consideration (including acquisition
costs) paid by the Company in connection with these transactions, totaling
$9,799,000, consisted of $4,619,000 in cash, $3,446,000 in notes payable,
143,333 shares of VCA common stock with a value of $1,037,000, and the
assumption of liabilities totaling $697,000.

 The non-recourse notes payable, with a principal amount of $3,663,000, to the
previous owners of the hospitals are secured by the assets of the acquired
hospitals.  The fair market value of the tangible assets acquired, including
accounts receivable, supplies, inventory and hospital equipment, totals
approximately $360,000.

 In 1993, VCA purchased six veterinary hospitals for a total consideration of
$4,113,000 consisting of $1,021,000 in cash, $2,967,000 in non-recourse notes
payable and the assumption of liabilities totaling $125,000.  In addition, the
Company paid $250,000 to acquire options to purchase the land and building of
two of the hospitals.  The obligations of the Company to the previous owners
pursuant to the non-recourse notes are secured by the assets of the companies
acquired.  The fair market value of the tangible assets acquired including
accounts receivable, supplies, inventory and hospital equipment, totals
approximately $295,000.  During 1993, the Company exercised its option to
purchase the land and building of one of its animal hospitals for total
consideration of approximately $1,296,000 consisting of a $436,000 option
payment made in 1992 and the assumption of a mortgage payable in the amount of
$860,000.

 All 1993 and 1994 acquisitions have been accounted for using the purchase
method of accounting. The operations of the acquired companies are included in
the accompanying consolidated financial statements from the date of acquisition.

 Since its inception, Pets' Rx has completed the acquisition of 19 veterinary
clinics (of which three have been merged into other clinics).  All of the
acquisitions were accounted for using the purchase method of accounting;
accordingly, the costs of these acquisitions have been allocated to assets
acquired based on their fair value at date of acquisition.  The results of the
acquired clinics are included in Pets' Rx results commencing from the date of
acquisition.

 During 1995, Pets' Rx acquired a veterinary hospital for a total consideration
of $218,000 consisting of $40,000 in cash, $25,000 in a secured promissory note
payable, $15,000 payable under covenants not to compete, $31,000 payable under
an assumed lease obligation, and $107,000 in other liabilities.

 During 1995, a limited liability company (LLC) was formed by combining a
veterinary clinic owned by Pets' Rx with the practice of another veterinary
clinic owned by an unrelated party. Certain assets were contributed by each
party to form the new entity, which is not liable for any contracts or for any
indebtedness relating to the predecessor clinics. The Company has an 80%
interest in the LLC.

 During 1994, Pets' Rx completed the acquisition of six veterinary hospitals for
total consideration of $4,031,000, consisting of $862,000 in cash, $2,529,000 in
secured promissory notes payable, $325,000 payable under covenants not to
compete, 2,154 shares of common stock valued at $15,000 and the assumption of
$300,000 of notes payable.

 During 1993, Pets' Rx completed the acquisition of four veterinary clinics for
total consideration of $6,733,000 consisting of $1,140,000 in cash, $5,350,000
in secured promissory notes payable, $200,000 payable under covenants not to
compete, and the assumption of $43,000 in trade and payroll liabilities.

4.  JOINT VENTURES

 In January 1993, the Company entered into a joint venture with Heinz Pet
Products, Vet's Choice, to develop, manufacture and market new pet products and
services.  The Company obtained a 50.5 percent controlling interest in the joint
venture for a capital contribution of $3,030,000 in cash and is the managing
general partner.  Heinz Pet Products  ("HPP"), contributed $2,970,000 in cash
for a 49.5 percent minority interest in the joint venture.  Under the terms of
the partnership agreement, HPP also agreed to make an additional capital
contribution of their product development costs of up to $1 million.  The actual
costs incurred during 1993 were $806,000.  Such costs were expensed and credited
to the minority interest partner's equity account.  Commencing January 1, 1996
the joint venture will make preferential distributions to HPP of any
distributable cash in excess of $3 million in any fiscal year until such time as
HPP has received preferential distributions amounting to the total development
costs that it contributed.  As provided by the partnership agreement, the
Company and Heinz Pet Products each contributed $1 million to the joint venture
in the third quarter of 1995.  The joint venture agreement between the Company
and HPP provides for restrictions on the transfer of each partner's respective
interest in the joint venture and for reciprocal buy-sell provisions.  Heinz Pet
Products has agreed to lend Vet's Choice up to $1.0 million at its bank prime
rate plus one-half percent for working capital.

 The Company operates Vet Research in a joint venture with VRI.  Vet Research's
operating results have been accounted for as part of the consolidated operations
of the Company.  Distributions of distributable cash will be made pursuant to a
formula contained in the operating agreement between the Company and VRI.
Pursuant to that formula, during each contract year, the first $1.5 million of
distributable cash is distributed to VRI; the next $3 million of distributable
cash is distributed to the Company; and the remaining distributable cash is
distributed 25 percent to the Company and 75 percent to VRI.  The Company has
recorded minority interest expense related to the joint venture based on the

 Certain acquisition debt of the Company included above and amounting to
$33,889,000  and $26,347,000 at December 31, 1995 and 1994, respectively, is
non-recourse debt secured solely by the assets or the stock of the veterinary
hospital acquired under security arrangements whereby the creditor's sole remedy
in the event of default is the contractual right to take possession of the
entire veterinary hospital regardless of the outstanding indebtedness at the
time of default.

 The Company has an unsecured line of credit of $3.1 million.  The line of
credit is at the bank prime rate (8.5 percent at December 31, 1995) and expires
in December 1996, at which time the outstanding balance on the line can, at the
Company's option, convert to a 36-month term loan.  At December 31, 1995, the
Company had $3.1 million available under the line.

 In April 1996, the Company received net proceeds of $82,697,000 related to the
sale, in an offshore offering and concurrent private placement in the United
States, of $84,385,000 of 5.25% convertible subordinated debentures due in 2006.
The debentures, non-callable for three years, are convertible into approximately
2.5 million shares of the Company's common stock at a rate of $34.35 per share.

 The following disclosure of the estimated fair value of the Company's debt is
made in accordance with the requirements of Statement of Financial Accounting
Standards No. 107 "Disclosures about Fair Value of Financial Instruments."  The
estimated fair value amounts have been determined by the Company using available
market information and appropriate valuation methodologies.

owners of certain acquired companies.  During 1995, 8,333 of these options were
exercised.  The options are exercisable at $.75 to $6.00 per share.  At December
31, 1995, 45,667 of the options are exercisable.

 In November 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 "Accounting for Stock-Based
Compensation."  The statement recommends changes in accounting for employee
stock-based compensation plans, and requires certain disclosures with respect to
these plans.  The Statement's disclosures were adopted by the Company effective
January 1, 1996.

8.  GUARANTEED PURCHASE PRICE CONTINGENTLY PAYABLE IN CASH OR COMMON STOCK

 The Company has guaranteed the value of certain shares of its common stock
issued in connection with the acquisition of certain animal hospitals in 1995.
If the aggregate market value of the stock (as quoted by a nationally recognized
stock exchange) at various specified valuation dates is below the value of the
stock on the acquisition date, the Company has agreed to pay the difference in
additional shares of stock, cash or notes payable.  The Company's guarantee of
the value, however, terminates if the common stock is registered for resale and
trades at 110% to 120% of the issue price of the stock for five to twenty
consecutive days.  At December 31, 1995, there were 404,495 shares of stock
outstanding with such guarantees, with issue prices ranging from $11.26 to
$14.95.

 In connection with certain acquisitions completed prior to 1995, the Company
guaranteed the price of certain shares of its common stock issued in connection
with the acquisitions.  If the aggregate market value of the stock (as quoted by
a nationally recognized stock exchange) had not reached the guaranteed value,
which exceeded the value of the stock at the acquisition date, by the various
specified valuation dates, the Company agreed to pay the difference in
additional shares of stock, cash, or notes payable.  The guaranteed purchase
price contingently payable in cash or common stock represents the liability for
the difference between the aggregate guaranteed value of the common stock net of
the Company's estimate of the fair market value of the stock at the date of the
acquisition, discounted at 10 percent.

 In 1995, pursuant to two of these stock guarantee arrangements pertaining to a
total of 13,494 shares, the Company paid $19,000 in cash for the difference
between the guaranteed value of the stock held and the market value of the
stock, as defined.  The difference between the $19,000 and the $72,000 liability
for the guaranteed purchase price contingently payable in cash or common stock,
amounting to $53,000 was credited to additional paid-in-capital.

 In 1994, pursuant to a stock guarantee arrangement for 80,000 shares, the
Company issued 63,214 shares of common stock for the difference between the
guaranteed value of the stock held and the market value of the stock, as
defined.  The market value of the additional shares issued, totaling $470,000,
was charged to the liability for the guaranteed purchase price contingently
payable in cash or common stock.

9.  COMMITMENTS

 The Company operates many of its hospitals from premises that are leased from
the hospitals' previous owners under operating leases with terms, including
renewal options, ranging from one to 35 years.

 The annual lease payments under the lease agreements have provisions for annual
increases based on the Consumer Price Index.  The Company also leases certain
medical and computer equipment under capital leases.

The future minimum lease payments at December 31, 1995 are as follows:

respectively.

 The Company has employment agreements with three officers of the Company which
currently expire on December 31, 1998.  Each of the agreements provide for
annual compensation (subject to upward adjustment) which aggregated $559,000 for
the year ended December 31, 1995.

10.  CALCULATION OF PER SHARE AMOUNTS

 Earnings per share calculations are based on the weighted average common shares
outstanding including obligated shares (Note 7) plus common shares subject to
dilutive stock options, common shares contingently issuable pursuant to the
guaranteed purchase price contingently payable in cash or common stock as
discussed in Note 8, convertible debt and shares issuable upon redemption of
redeemable warrants and conversion of preferred stock.  Stock options, common
shares contingently issuable and shares issuable upon conversion of preferred
stock are not included in the weighted average common shares in 1995, 1994 and
1993 as they have an anti-dilutive effect.

 Effective January 1, 1993, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
109").  SFAS 109 requires recognition of deferred tax liabilities and assets for
the expected future tax consequences of events that have been included in the
financial statements or tax returns.  Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to reverse.
The Company reflected the impact as a cumulative adjustment in the 1993 first
quarter and did not restate prior periods.  The cumulative adjustment had a
favorable impact of $221,000 on the net loss.

The net deferred tax asset (liability) is comprised of the following:

 For financial reporting purposes, the benefit arising from the utilization of
operating loss carryforwards generated by companies prior to their acquisition
by VCA is accounted for as a reduction of goodwill of the acquired companies.
Such benefit amounted to $40,000 and $69,000 for the years ended December 31,
1993 and 1995, respectively.  No benefit was realized for the year ended
December 31, 1994.  For tax reporting purposes, the acquired companies have
Federal net operating loss carryforwards at December 31, 1995 of approximately
$260,000 expiring through 2003.

 At December 31, 1995, Pets' Rx has federal and state net operating loss ("NOL")
carryforwards of approximately $6.5 million and $3.2 million, respectively.
These NOL carryforwards expire at various dates through 2010 and 2000,
respectively.

 Under the Tax Reform Act of 1986, the utilization of NOL carryforwards to
reduce taxable income will be restricted in certain circumstances.  Events which
cause such a limitation include, but are not limited to, a cumulative ownership
change of more than 50% over a three year period.  Management believes that the
issuance of convertible preferred stock during 1994 and the merger with VCA
caused such a change in ownership and, accordingly, utilization of the Pets' Rx
NOL carryforwards may be limited in future years.

12.  401(K) PLAN

 During 1992, the Company established a voluntary retirement plan under Section
401(k) of the Internal Revenue Code.  The plan covers all eligible employees and
provides for annual matching contributions by the Company at the discretion of
the Company's board of directors.  In 1995, 1994 and 1993, the Company provided
a matching contribution of 20 percent, 20 percent and 15 percent, respectively
of the first five percent of the employees' contributions, as defined.  Such
matching contributions approximated $87,000, $46,000 and $24,000 in 1995, 1994
and 1993, respectively.

13.  WRITEDOWN OF ASSETS

 During 1993, the Company charged $4,506,000 to operations related to the
writedown of goodwill and certain intangible assets at three VCA facilities and
five Pets' Rx facilities. The determination to writedown these assets was based
on the Company's estimate that forecasted losses at each facility indicated that
the intangible assets would not be realized.

 The first of the three hospitals was purchased in March 1989, with goodwill on
the acquisition of $920,000.  In the five years subsequent to the acquisition,
the hospital generated losses aggregating $84,000 through December 31, 1993, due
primarily to severe competition in the area from the veterinarian from whom the
Company acquired the hospital.  In January 1994, the economy in the area where
the hospital operates was adversely impacted by the "Northridge Earthquake,"
further impacting the hospital's revenues and operating results.

 The second hospital was purchased in December 1989, at a price of approximately
$1 million, with goodwill on the acquisition of $997,000.  Since the
acquisition, the hospital generated aggregate net income of $250,000 through
December 31, 1993, including a loss of $44,000 in 1992 and income of $17,000 in
1993.  Included in the operating results is income of $73,000 in 1992 and
$39,000 in 1993 from the rental of space at the facility to a veterinary surgery
referral practice.  The rental agreement was terminated in July 1993 and, due to
the specialization of the services provided by the referral practice, the
hospital was unable to find a suitable replacement.  In addition to the impact
of the loss of rental income, the hospital's revenue and income were adversely
impacted by the loss of referral business from the referral practice. The
departure of the group had a permanent negative impact on the hospital's net
income and the recoverability of goodwill.

 The third hospital was purchased in December 1991 at a price of approximately
$800,000, with goodwill and other intangible assets on the acquisition of
$778,000.  The hospital generated net income in 1992 of $52,000 and a net loss
in 1993 of $59,000.  The hospital provided 24-hour emergency service under an
arrangement whereby a veterinary emergency group used the hospital space during
the hours that the regular hospital was closed.  The emergency clinic's
presence in the hospital provided substantial indirect benefits to the
hospital's operating results.  In September 1993, the emergency group terminated
its arrangement with the hospital, and the operating results were adversely
impacted.  The Company has determined that emergency services cannot be replaced
and the impact on the hospital will be permanent.

 In 1993, Pets' Rx recognized a writedown of goodwill of $123,000 related to a
hospital that was closed in early 1994.

 As a result of conforming to consistent methods of accounting, four hospitals
acquired by Pets' Rx in early to mid-1992 became impaired in 1993. Three of the
four hospitals are located in the Sacramento area, a market which had not
matured as anticipated. These three hospitals had losses excluding amortization
of intangible costs totaling $91,000 for 1993. The fourth hospital located in
the San Jose market had also not matured as anticipated and recorded a loss
excluding amortization of $76,000 in 1993 resulting in a writedown for the four
hospitals of $2,073,000.

 As of late 1995, it was further determined that three hospitals acquired by
Pets' Rx in late 1993 and 1994 were impaired.  One hospital acquired in late
1994 is also located in the depressed Sacramento market and its addition failed
to improve the overall Sacramento region performance.  The remaining hospitals'
performance reflect factors specific to their operations and location and are
not indicative of the San Jose and Las Vegas markets.  These three hospitals
recorded losses totaling $206,000 in 1995 and resulted in a writedown of
$2,148,000.

 The Company's goal over the next two years is to minimize the facilities' cash
flow requirements and ultimately bring the facilities to a breakeven status.
The Company's strategy of building a network of hospitals in the markets they
serve will be benefited by the hospitals' ability to provide services to
customers in their vicinity, even though the facilities will not generate
profits.

14.  RESTRUCTURING CHARGE

 The operations of Cenvet were merged into VRI's operations to form Vet Research
in March 1995.  The combined operations were  restructured to eliminate
duplicate operating and overhead costs.  The restructuring included the
consolidation of facilities, staff reductions and the consolidation of ancillary
operations.  In connection with the restructuring, the Company recorded a charge
of

                                    F-80

$1,086,000 in the first quarter of 1995 to accrue the estimated costs associated
with the restructuring, consisting primarily of lease termination and severance
costs.

The following is a summary of the restructuring costs:

 During 1995, the Company utilized $237,000 of the reserve for restructuring.
At December 31, 1995, $849,000 of the restructuring reserves remained on the
Company's balance sheet.

15.  LINES OF BUSINESS

 The Company classifies its business operations into three segments:  Animal
Hospital, Premium Pet Food and Laboratory.  Prior to January 1993, the Company's
principal line of business was owning and operating animal hospitals.  On
January 1, 1993, the Company formed a joint venture, Vet's Choice, to develop,
market and distribute new pet products and services (Note 4).  Vet's Choice
began generating revenue in March 1994 when it commenced distribution of its
first product line.  In March 1994, the Company acquired Professional Animal
Laboratory and combined its existing laboratory to form the Laboratory segment.

16.  SUBSEQUENT EVENTS

 During 1996 through June 18, 1996, the Company purchased eleven veterinary
hospitals and three veterinary diagnostic laboratories (See Note 3).

 On March 21, 1996, the Company signed a definitive merger agreement with The
Pet Practice, Inc. ("TPP"), pursuant to which the Company will acquire all of
the outstanding securities of TPP.  TPP operates 86 veterinary hospitals in 11
states.

 Under the terms of the agreement, each share of TPP common stock will be
converted into a fraction of a share of VCA common stock determined by a
reference to the average closing price of VCA common stock over the twenty
trading days ending on the third day before the shareholder meetings at which
the stockholders of VCA and TPP will consider the merger.  If the average price
of the VCA common stock ranges from $25 to $30 per share, the exchange ratio
shall be determined by dividing $10 by the average price of the VCA common
stock, resulting in a valuation of $10 per share of TPP common stock throughout
the range.  If the average closing price of the VCA common stock is less than
$24 per share, the exchange ratio will be increased (from 0.395 shares at $24
per share) by 0.005 for each dollar of such reduction down to $18.50 of VCA
common stock, and if the average price of VCA common stock is more than $31 per
share, the exchange ratio shall be reduced (from 0.3350 at $31 per share) by
0.005 for each dollar of such increase, up to $49.00 per share.  No further
adjustment shall be made if the price of VCA stock shall be less than

                                    F-81

              NOTES TO SUPPLEMENTAL COMBINED FINANCIAL STATEMENTS

         (Information with respect to the unaudited three months ended
    March 31, 1996 and 1995 is not covered by report of independent public 
                                  accountants)

$18.50.  In each case, a proportionate reduction or increase, as the case may
be, shall be made if the price of VCA common stock is less than a round dollar.
If the average price of the VCA common stock is greater than $49.00, the
exchange ratio should be determined by dividing $12.005 by the average price.
By way of illustration, at $23 per share of VCA common stock, the exchange ratio
shall be 0.400, resulting in a valuation of $9.20 per share of TPP common stock.
At $32.00 per share of VCA common stock, the exchange ratio shall be 0.330,
resulting in a valuation of $10.56 per share of TPP common stock.  The Company
expects that the merger will be consummated in the second quarter of 1996.  The
merger will be accounted for as a purchase.  Each party has the right to
terminate the definitive agreement if the average price of VCA common shares is
$18.50 or less.

 Consummation of the merger is subject to certain significant conditions.
Consequently, the merger of VCA and TPP may never be consummated.

immediately prior to the Effective Time (except any share of Company Preferred
Stock held by a Dissenter immediately prior to the Effective Time) shall entitle
the holder thereof to that number of validly issued, fully paid and non-
assessable Merger Shares (including any fractional share) as is equal to the
number of shares of Company Common Stock into which such share of Company
Preferred Stock is convertible immediately prior to the Effective Time
multiplied by the Exchange Factor;

<PAGE>
 
                 2.5.3   no fractional shares of Parent Common Stock will be
issued, but in lieu thereof, any Company Securityholder who would otherwise be
issued a fractional share of Parent Common Stock after aggregating all of the
Merger Shares otherwise issuable to him in the Merger, shall be paid cash equal
to the value of such fractional share, based on the average per share closing
sales price of the Parent Common Stock as reported by the National Association
of Securities Dealers, Inc. National Market System (the "NMS") for the five
trading days ending two days prior to the Closing Date (the "Parent Per Share
Value");

                 2.5.4   each share of Company Common Stock and Company
Preferred Stock held by a Dissenter immediately prior to the Effective Time
shall entitle the holder thereof to receive the cash consideration determined
and payable in accordance with Section 262 of the Delaware Law, except as
otherwise agreed by the Company, Parent and the Dissenter; and

          2.6    ESCROW OF MERGER CONSIDERATION. Notwithstanding the provisions
of this Article 2, the Parent shall place in escrow pursuant to the terms of
Section 8.10 hereof and the Escrow Instrument in effect pursuant thereto that
number of Merger Shares equal to 10% of the total Merger Shares.

          2.7    DELIVERY OF CERTIFICATES. On or before the tenth day after the
Closing Date, the Parent shall make available, and each holder of Company
Securities other than the Dissenters shall be entitled to receive, upon
surrender to the Parent or its representatives of any certificate or
certificates evidencing such Company Securities (the "Certificates") for
cancellation, the aggregate Merger Shares into which such Company Securities
have been converted in the Merger, and, upon such surrender of each Certificate
and delivery by the Company of the aggregate number of Merger Shares in exchange
therefor, such Certificates shall forthwith be cancelled. Until so surrendered,
each Certificate shall be deemed for all corporate purposes to evidence only the
right to receive upon such surrender the aggregate number of Merger Shares into
which the Company Securities represented thereby shall have been converted.

          2.8    PURCHASE RIGHTS. Each of the Company Purchase Rights shall,
subject to the terms of any applicable stock option or warrant agreement, remain
outstanding following the Effective Time. At the Effective Time, such Company
Purchase Rights shall, by virtue of the Merger and without any further action on
the part of the Company, MergerCo, Parent or the holder of any Company Purchase
Right, be assumed by the Parent in such manner that the Parent (x) is a
corporation "assuming a stock option in a transaction to which Section 424
applied" within the meaning of Section 422 of the Code or (y) to the extent
Section 424 of the Code does not apply to any such Company Purchase Rights,
would be such a corporation were Section 424 applicable to such option. Each
Company Purchase Right assumed by the Parent shall be exercisable upon the same
terms and conditions as under the applicable stock option or warrant agreement,
except that (i) each such Company Purchase Right shall be exercisable for that
number of shares of Parent Common Stock (to the nearest whole share) into which
the Company Option Shares subject to such Company Purchase Right immediately
prior to the

                                       9
<PAGE>
 
Effective Time would be converted under Section 2.5.1 or 2.5.2 of this
Agreement, and (ii) the option price per share of Parent Common Stock shall be
equal to (x) the per share exercise price of such Company Purchase Right in
effect immediately prior to the Effective Time multiplied by the number of
Company Option Shares subject to such Company Purchase Right immediately prior
to the Effective Time, divided by (y) the number of shares of Parent Common
Stock subject to such Company Purchase Right immediately after the Effective
Time. No payment shall be made for fractional interests. In connection with the
assumption of the Company Purchase Rights, the Parent shall effect such
assumption in such manner as not to affect the "incentive" status of those
options which are "incentive" stock options within the meaning of the Code at
the Effective Time. From and after the date hereof, no additional Company
Purchase Rights shall be granted by the Company and no "vesting" or exercise
schedule of any Company Purchase Rights shall be modified or accelerated (other
than pursuant to the express terms of such Company Purchase Right) and no
exercise price of any Company Purchase Right shall be modified.

          2.9    CLOSING OF TRANSFER BOOKS. At and after the Effective Time,
transfers of the shares of Company Common Stock and Company Preferred Stock
outstanding immediately prior to the Effective Time shall not be made on the
stock transfer books of the Company.

          2.10   DISSENTING STOCKHOLDERS.  All issued and outstanding shares of
Company Common Stock and Company Preferred Stock held by holders of record as of
the date fixed for determination of stockholders entitled to notice of and to
vote at the meeting of the Company Stockholders who shall have neither voted in
favor of the Merger nor consented thereto in writing and shall have delivered
(and then been entitled to deliver) to the Company a written demand for
appraisal of their shares of Company Common Stock and/or Company Preferred Stock
within the time and in the manner provided in Section 262 of the Delaware Law
(individually, a "Dissenter," and collectively, the "Dissenters") shall not be
converted into Parent Common Stock, but shall be entitled to receive such
consideration as shall be provided in Section 262 in accordance with the terms
and subject to the conditions set forth in said Section 262, except that each
share of Company Common Stock and Company Preferred Stock issued and outstanding
immediately prior to the Effective Time and held by a Dissenter who shall
thereafter withdraw his demand for appraisal of his shares of Company Common
Stock and/or Company Preferred Stock with the Surviving Corporation's consent or
lose his right to such payment as provided in Section 262 shall be deemed
converted, as of the Effective Time, into fully paid and nonassessable shares of
Parent Common Stock, in which event such stockholder shall no longer be a
Dissenter.  The Company shall deliver to the Parent (i) on the first business
day following the meeting of Company Securityholders (or the twenty first (21st)
day following notice of written consent), a list of all holders of Company
Common Stock and Company Preferred Stock who have filed written demands for
payment of their shares of Company Common Stock and/or Company Preferred Stock
by the date of such meeting in accordance with said Section 262, and (ii) from
time to time, as the Parent shall reasonably request, other relevant information
with respect to such objections and demands.  The Company shall afford

                                       10
<PAGE>
 
to the Parent the opportunity to participate in all negotiations and proceedings
with respect to any such demands and shall not, prior to the Effective Time,
except with the prior written consent of the Parent, voluntarily make any
payment with respect to, settle or offer or agree to settle, any such demands
for payment.

          2.11   DISSENTER PAYMENT.  Each Dissenter who becomes entitled,
pursuant to the provisions of Section 262 of the Delaware Law, to payment for
the shares of Company Common Stock and/or Company Preferred Stock held by such
Dissenter shall receive the payment therefor provided under Section 262 from the
Surviving Corporation (less amounts to be placed in escrow pursuant to Section
8.10 hereof), but only up to the amount of such payment as shall have been
agreed upon or finally determined pursuant to Section 262, and such shares shall
thereupon be cancelled.

          2.12   LOST CERTIFICATES.  Notwithstanding the provisions of Section
2.7, in the event any certificate representing Company Securities has been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such certificate to be lost, stolen or destroyed and an agreement to
indemnify the Parent against any claim that may be made against it with respect
to such certificate, the Parent will issue in exchange for such lost, stolen or
destroyed certificate the aggregate number of Merger Shares into which such
Company Securities would have been converted and any fractional payment due in
connection therewith pursuant to Section 2.5.

                 ---------------------------------------------

     The Company represents and warrants to and agrees with the Parent and
MergerCo as set forth below. All representations and warranties of the Company
are made subject to the exceptions with respect thereto which are noted in the
Schedule to be delivered by the Company

<PAGE>
 
to MergerCo and the Parent pursuant to Section 6.11 and identified as the
"Disclosure Schedule." The representations and warranties set forth below shall
 -------------------
be effective as of the date that the final draft of the Disclosure Schedule is
delivered to MergerCo and Parent pursuant to Section 6. 11, as certified in a
writing executed by Parent and the Company.

          4.1    ORGANIZATION AND STANDING; CHARTER DOCUMENTS AND BY-LAWS. Each
of the Company and the Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of the state of its incorporation.
Each of the Company and the Subsidiaries is qualified, licensed or domesticated
as a foreign corporation and is in good standing in all jurisdictions where the
character of its properties owned or held under lease or the nature of the
business conducted by it make such qualification necessary except where the
failure to be so qualified would not have a Material Adverse Effect. Each of the
Company and the Subsidiaries has the requisite corporate power and corporate
authority to own, lease and operate its properties and assets and to carry on
its business in the manner and in the locations as presently conducted. The
state of incorporation of the Company and the Subsidiaries and each foreign
jurisdiction in which any of them are qualified are set forth in Section 4.1 of
the Disclosure Schedule. True and correct copies of the charter documents and 
by-laws of each of the Company and the Subsidiaries (the "Company Organizational
Documents") have been delivered to Parent.

          4.2    AUTHORIZATION. Subject to the stockholder approval required by
Section 6.3, the Company has the corporate power and authority to enter into
this Agreement and each of the Ancillary Agreements and to carry out its
obligations hereunder and thereunder. The execution and delivery of this
Agreement and each of the Ancillary Agreements and the consummation of the
transactions contemplated hereby and thereby have been duly and validly
authorized by the Company's Board of Directors and, other than the stockholder
approval required pursuant to Section 6.3 hereof, all corporate proceedings have
been taken and no other corporate proceedings on the part of the Company are
necessary to authorize the execution, delivery and performance by the Company of
this Agreement and each of the Ancillary Agreements. The execution, delivery and
performance of this Agreement and each of the Ancillary Agreements by the
Company will not conflict with or constitute a breach, violation or default
under the Company Organizational Documents, any statute, law or administrative
regulation, or under any judgment, decree, order, writ, governmental permit or
license, any Material Contract or any other agreement, lease, indenture or
instrument to which the Company or any of the Subsidiaries is a party or by
which the Company or any of the Subsidiaries is bound, which breach, violation
or default would have a Material Adverse Effect on the Company and its
Subsidiaries. This Agreement and each of the Ancillary Agreements have been duly
executed and delivered by the Company and constitute the valid and binding
obligations of the Company enforceable in accordance with their terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or affecting creditors'
rights generally and except that equitable remedies may not in all cases be
available (regardless of whether enforceability is considered in a proceeding at
law or in equity) (collectively, the "Remedies Exception").

          4.3    CAPITAL STOCK. The authorized capital stock of the Company and
a listing of all Company Securities which are currently outstanding is set forth
on Schedule 4.3. All of the issued and outstanding Company Securities have been
   ------------
duly authorized, validly issued, fully paid and are non-assessable and were not
issued in violation of any preemptive rights or any Federal or state securities
laws. Except with respect to the Convertible Preferred Stock, the Principal
Stockholders collectively own a majority of the issued and outstanding stock of
each class of Company Securities on a fully diluted basis. Section 4.3 of the
Disclosure Schedule lists the names of each of the Company Securityholders and
the class and number of Company Securities held by each such Company
Securityholder. All Company Purchase Rights were granted by the Company at
option or exercise prices not less than the fair market value of the Company
Option Shares subject thereto as of the time of grant as determined in good
faith by the Board of Directors of the Company. Other than as set forth in
Section 4.3 of the Disclosure Schedule, there are no other authorized, issued or
outstanding shares of the capital stock of the Company or any options, warrants,
convertible securities or other rights (including stock appreciation rights),
subscription rights (including preemptive rights), calls, agreements,
understandings, arrangements or commitments obligating the Company now or at any
time in the future to issue shares of its capital stock.

          4.4    SUBSIDIARIES AND AFFILIATES AND OTHER NAMES. The Company does
not have any Subsidiaries or own any equity interest or other securities or
ownership interest in any entity other than as set forth in Section 4.4 of the
Disclosure Schedule. All of the outstanding capital stock of each such
Subsidiary is owned entirely by the Company or by a Subsidiary, as the case may
be, as of the date hereof, free and clear of all Claims. All such shares of
capital stock have been duly authorized and validly issued and are fully paid
and nonassessable. None of such Subsidiaries has any outstanding subscriptions,
options, warrants, rights or other agreements or commitments obligating it to
issue or sell any shares of its capital stock, or any other equity interest, or
any securities or obligations convertible into or exchangeable for any shares of
capital stock of, or any other equity interest in, such Subsidiary. There are no
agreements, understandings or undertakings governing the rights and duties of
the Company or any Subsidiary as a shareholder of any Subsidiary, including,
without limitation, any agreement arrangement or understanding under which the
Company or any Subsidiary is or may become obligated, directly or indirectly, to
acquire or dispose of any equity interest in, make any capital contribution or
extend credit to, or act as guarantor, surety or indemnitor for any liability of
any Subsidiary. The Company (including any entity merged into or consolidated
with the Company or a predecessor to the Company's business) has not been known
as or used any name for itself or any of its operations other than the name Pets
Rx, Inc.

          4.5    NO CONSENTS. No consent, authorization, order or approval of,
or filing with or registration with, any governmental authority, commission,
board or other regulatory body of the United States or any state or political
subdivision thereof, or any other Person, is required to be made or obtained by
the Company for or in connection with the execution and delivery by the Company
and the Principal Stockholders of this Agreement, the Ancillary Agreements and
the Stockholder Ancillary Agreements and the consummation by the Company

and the Principal Stockholders of the transactions contemplated hereby and
thereby, the absence of which would have a Material Adverse Effect on the
Company or on the operations of any individual Veterinary Hospital other than
the filing of the Certificate of Merger with the Delaware Secretary of State and
filings made pursuant to the Hart Scott Act.

          4.6    FINANCIAL STATEMENTS. The books, accounts and records of the
Company and its Subsidiaries are, and have been, maintained in the Company's or
its Subsidiaries' usual, regular and ordinary manner, in accordance with GAAP,
consistently applied. The Company heretofore delivered to the Parent copies of
consolidated financial statements of the Company and its Subsidiaries (the
"Audited Financial Statements") consisting of consolidated balance sheets as of
December 30, 1994 and 1993 and consolidated statements of earnings,
stockholders' equity and cash flows for each of the Company's three fiscal years
in the period ended December 30, 1994, together with appended notes which are an
integral part thereof, all of which have been audited and certified by Price
Waterhouse LLP, certified public accountants. The Company heretofore delivered
to the Parent copies of consolidated unaudited financial statements of the
Company and its Subsidiaries (the "Interim Financial Statements") consisting of
a balance sheet, statements of earnings, stockholders' equity and cash flows for
the eleven (11) month period ending November 30, 1995. All of the Audited
Financial Statements and the Interim Financial Statements, including any
appended notes which are an integral part of such statements, have been prepared
in conformity with GAAP applied on a consistent basis throughout the periods
covered thereby, each balance sheet therein presents fairly the consolidated
financial position of the Company and its Subsidiaries as at its respective date
and each statement of earnings, stockholders' equity and cash flows presents
fairly the consolidated results of operations, stockholders' equity and cash
flows, respectively, of the Company and its Subsidiaries for the period covered
thereby subject in the case of the Interim Financial Statements to normal
recurring year-end adjustments and any other adjustments described therein and
the lack of footnotes which would be required by GAAP were such financial
statements audited.

          4.7    LIABILITIES.  The Company and its Subsidiaries do not have any
obligations or liabilities (direct or indirect, matured or unmatured, absolute,
accrued, contingent or otherwise) whether or not required by GAAP to be
reflected or reserved against on a balance sheet ("Liabilities") other than (a)
Liabilities provided for or reserved against in the Audited Financial Statements
or Interim Financial Statements, or (b) Liabilities incurred in the ordinary
course of business consistent with past practice since the date of the Interim
Financial Statements.  None of the Liabilities described above relates to or
has arisen out of a breach of contract, breach of warranty, tort or infringement
by or against the Company or any of its Subsidiaries or any claim or lawsuit
involving the Company or any of its Subsidiaries.

          4.8    ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since the date of the
Interim Financial Statements, each of the Company and its Subsidiaries has
conducted its business only in the ordinary and usual course consistent with
past practice or as required for the consummation of the transactions
contemplated by this Agreement, and there has not been:

by it and has not assigned or agreed to assign to anyone other than Parent any
such lease.

          4.10   TANGIBLE PERSONAL PROPERTY.  The Company and its Subsidiaries
have good and marketable title to or a valid right to use all of its tangible
personal property, free and clear of any and all Claims other than any Claim or

of the Parent and MergerCo is a corporation duly organized, validly existing and
in good standing under the laws of the state of its incorporation.  Each of the
Parent and MergerCo is qualified, licensed or domesticated as a foreign
corporation and is in good standing in all jurisdictions where the character of
its properties owned or held under lease or the nature of its activities make
such qualification necessary, except where the failure to so qualify will not
have a Material Adverse Effect.  Each of the Parent and MergerCo has full
corporate power and authority necessary to own, lease and operate its properties
and assets and to carry on its business in the manner and in the locations as
presently conducted.

          5.2    AUTHORIZATION.  The Parent and MergerCo have the requisite
corporate power and authority to enter into and carry out the terms and
conditions of this Agreement, the Ancillary Agreements and the Stockholder
Ancillary Agreements to which they are a party and to carry out their
obligations hereunder and thereunder.  When the execution and delivery of this
Agreement and each of the Ancillary Agreements and the consummation of the
transactions contemplated hereby and thereby are duly and validly authorized by
the Parent's and MergerCo's Board of Directors, all corporate proceedings will
have been taken and no other corporate proceedings on the part of the Parent or
MergerCo are necessary to authorize the execution,

                                       27

delivery and performance by the Parent and MergerCo of this Agreement and each
of the Ancillary Agreements.  The execution, delivery and performance of this
Agreement, each of the Ancillary Agreements and the Stockholder Ancillary
Agreements by Parent and MergerCo will not conflict with or constitute a breach,
violation or default under their respective charter documents and bylaws, any
statute, law or administrative regulation, or under any judgment, decree, order,
writ, governmental permit or license, and Material Contract or any other
agreement, lease, indenture or instrument to which Parent, any of its
Subsidiaries or MergerCo is bound, which breach, violation or default would have
a Material Adverse Effect on Parent, its Subsidiaries and MergerCo.  This
Agreement, each of the Ancillary Agreements and the Stockholder Ancillary
Agreements have been duly executed and delivered by the Parent and MergerCo and
constitute the legal, valid and binding obligations of the Parent and MergerCo,
enforceable against the Parent and MergerCo in accordance with their respective
terms, subject to the Remedies Exception.

          5.3    VALIDITY OF MERGER SHARES.  Upon delivery of the certificates
for the Merger Shares pursuant to the terms of this Agreement, due
countersignature of the certificates by Parent's transfer agent and delivery to
the Company Securityholders receiving Merger Shares pursuant to this Agreement,
the Merger Shares to be issued by the Company represented thereby will be duly
authorized and validly issued, fully paid and nonassessable.

          5.4    SEC REPORTS.  The Parent has heretofore furnished to the
Company a true and complete copy of its Registration Statement on Form S-3,
declared effective by the SEC on November 8, 1995, its Annual Reports on Form
10-K for each of the fiscal years ended December 31, 1993 and 1994 and its
Quarterly Reports on Form 10-Q for each of the fiscal quarters ended March 31,
1995, June 30, 1995 and September 30, 1995, as filed with the SEC.  Parent has
not filed prior to the date hereof, any definitive reports or statements with
the SEC since November 8, 1995 other than pursuant to Item 5 of Form 8-K and
since November 8, 1995 there does not exist any circumstance, nor has any event
occurred, which has had a Material Adverse Effect on the Parent and its
Subsidiaries.  As of their respective dates, such reports and statements
complied as to form in all material respects with the requirements applicable
thereto and did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  The audited financial statements and unaudited interim
financial statements of the Parent included or incorporated by reference in such
reports have been prepared in accordance with GAAP applied on a consistent basis
(except as may be indicated therein or in the notes thereto) and fairly present
the consolidated assets, liabilities and financial position of the Parent as at
the dates thereof and the consolidated results of operations and changes in
financial position for the periods then ended, subject in the case of the
unaudited interim financial statements, to normal, recurring year-end
adjustments and any other adjustments described therein.

          5.5    NO CONSENTS.  No consent, authorization, order or approval of,
or filing with or registration with, any governmental authority, commission,
board or other regulatory

                                       28

other Person, is required to be made or obtained by Parent or MergerCo for or
the execution and delivery by Parent and MergerCo, of this Agreement, the
Ancillary Agreements and the Stockholder Ancillary Agreements and the
consummation by Parent and MergerCo of the transactions contemplated hereby and
thereby other than filings under the Securities Act, the Exchange Act, state
blue sky laws, the Hart Scott Act and the filing of the Certificate of Merger
with the Delaware Secretary of State.

          5.6    COMPLIANCE WITH APPLICABLE LAW.  The businesses of Parent, its
Subsidiaries and MergerCo are not being conducted in violation of any applicable
law, ordinance, regulation, decree or order of any governmental entity, except
for violations which either singly or in the aggregate do not and are not
expected to have a Material Adverse Effect on Parent, its Subsidiaries and
MergerCo.  Neither Parent, its Subsidiaries nor MergerCo is a party to or
subject to any judgment, decree, or order entered in any suit or proceeding
brought by any governmental agency or by any other Person, enjoining Parent, its
Subsidiaries or MergerCo with respect to any business practice, the acquisition
of any property, or the conduct of business in any area.

          5.7    NO BROKERS.  Neither the Parent nor MergerCo dealt with any
Person who is or may be entitled to a broker's commission, finder's fee,
investment banker's fee or similar payment for arranging the transactions
contemplated hereby or introducing the parties to each other.

          5.8    INFORMATION.  All written information provided to the Company
or its agents by or on behalf of the Parent or any of its representatives
(including, without limitation, each representation and warranty of the Parent
set forth in this Agreement) is, and the Parent covenants that any such
information provided hereafter shall be, true and correct in all material
respects and does not, or shall not, omit any material fact required to be

forecasts or projections previously furnished to the Company by the Parent,
except that such financial forecast or projection has been prepared in good
faith based on assumptions that are believed by the Parent to have been
reasonable at the time or times made; and provided further that no party shall
be deemed to be in breach of this Section 5.8 if (x) any misstatement or
omission is corrected by other written information provided to the Company, or
(y) any misstatement or omission is not material in light of all of the
information contained in this Agreement, the Exhibits and Schedules attached
hereto and all other written information supplied to the Company, taken as a
whole.

          5.9    REGISTRATION STATEMENT.  The Form S-3, at the time it becomes
effective under the Securities Act, will comply as to form in all material
respects with the requirements of the Securities Act, and will not contain any
untrue statement of a material fact, or omit to state any material fact required
to be stated therein or necessary in order to make the

                 9.1.5   LIMITATION ON INDEMNIFICATION OBLIGATIONS.

                         (a)  The Company's, each Principal Stockholder's and
the Parent's obligations pursuant to Sections 9.1.2, 9.1.3 and 9.1.4,
respectively, are subject to the following limitations:

                              (i)    No Indemnified Party shall be entitled to
recover under this Section 9.1 other than with respect to the Special Provisions

                 9.1.6   RELEASE.  As a condition to the Merger, each Company
Stockholder and each officer and director of the Company and its Subsidiaries
shall deliver to Parent, MergerCo and the Company effective as of the Closing
Time, a general release in a form reasonably satisfactory to Parent of the
Company and its Subsidiaries from all claims which such Principal Stockholder,
officer or director have against the Company or any Subsidiary on any account
other than rights specifically granted under this Agreement, which general
release shall be included in the Investment Letter.

                 9.1.7   ESCROW SHARES.  If the Escrow Instrument is in effect
at the time of an assertion of indemnification is made by the Parent
Indemnitees, the obligations of the Company and the Principal Stockholders
hereunder with respect to the Damages (other than with respect to the Special
Provisions) shall first be satisfied by the distribution to the Parent
Indemnitee of Escrow Shares held pursuant to the Escrow Instrument. After there
are no Escrow Shares (or other assets) held pursuant to the Escrow Instrument,
the Company and the Principal Stockholders shall be obligated to satisfy their
obligations by the payment of cash to the Parent Indemnitees.

                 9.1.8   THIRD PARTY CLAIMS OTHER THAN TAXES.  Forthwith
following the receipt of notice of a Third Party Claim (other than a Third Party
Claim with respect to Taxes), the party receiving the notice of the Third Party
Claim shall (i) notify the other party of its existence setting forth with
reasonable specificity the facts and circumstances of which such party has
received notice and (ii) if the party giving such notice is an Indemnified
Party, specifying the basis hereunder upon which the Indemnified Party's claim
for indemnification is asserted. The Indemnified Party shall, upon reasonable
notice, tender the defense of a Third Party Claim to the Indemnifying Party. If:

                         (a)  the defense of a Third Party Claim so tendered is
accepted without qualification (or reservation of rights) by the Indemnifying
Party within thirty (30) days thereafter such tender; or

                         (b)  within thirty (30) days after the date on which
written notice of a Third Party Claim has been given pursuant to this Section
9.1.8, the Indemnifying Party shall acknowledge in writing to the Indemnified
Party and without qualification (or reservation of rights) its indemnification
obligations as provided in this Section 9.1.8;

                         (c)  the defense of a Third Party Claim is accepted by
the Indemnifying Parties pursuant to Section 9.1.8(a) or (b) above, then, except
as hereinafter provided, the Indemnified Party shall not, and the Indemnifying
Party shall, have the right to contest, defend, litigate or settle such Third
Party Claim. The Indemnified Party shall have the right to be represented by
counsel at its own expense in any such contest, defense, litigation or
settlement conducted by the Indemnifying Party provided that the Indemnified
Party shall be entitled to reimbursement therefor if the Indemnifying Party
shall lose its right to contest, defend, litigate and settle the Third Party
Claim as herein provided. The Indemnifying Party

                                       43
<PAGE>
 
shall lose its right to defend and settle the Third Party Claim if it shall fail
to diligently contest the Third Party Claim.  So long as the Indemnifying Party
has not lost its right and/or obligation to contest, defend, litigate and settle
as herein provided, the Indemnifying Party shall have the exclusive right to
contest, defend and litigate the Third Party Claim and shall have the exclusive
right, in its discretion exercised in good faith, and upon the advice of
counsel, to settle any such matter, either before or after the initiation of
litigation, at such time and upon such terms as it deems fair and reasonable,
provided that at least ten (10) days prior to any such settlement, written
notice of its intention to settle shall be given to the Indemnified Party.  All
expenses (including without limitation attorneys' fees) incurred by the
Indemnifying Party in connection with the foregoing shall be paid by the
Indemnifying Party.  Notwithstanding the foregoing, in connection with any
settlement negotiated by an Indemnifying Party, no Indemnified Party shall be
required by an Indemnifying Party to (x) enter into any settlement that does not
include as an unconditional term thereof the delivery by the claimant or
plaintiff to the Indemnified Party of a release from all liability in respect of
such claim or litigation, (y) enter into any settlement that attributes by its
terms liability to the Indemnified Party or (z) consent to the entry of any
judgment that does not include as a term thereof a full dismissal of the
litigation or proceeding with prejudice.  No failure by an Indemnifying Party to
acknowledge in writing its indemnification obligations under this Section 9.1.8
shall relieve it of such obligations to the extent they exist.  If an
Indemnified Party is entitled to indemnification against a Third Party Claim,
and the Indemnifying Party fails to accept a tender of, or assume, the defense
of a Third Party Claim pursuant to this Section 9.1.8 or if, in accordance with
the foregoing, the Indemnifying Party shall lose its right to contest, defend,
litigate and settle such a Third Party Claim, the Indemnified Party shall have
the right, without prejudice to its right of indemnification hereunder, in its
discretion exercised in good faith and upon the advice of counsel to contest,
defend and litigate such Third Party Claim, and may settle such Third Party
Claim, either before or after the initiation of litigation, at such time and
upon such terms as the Indemnified Party deems fair and reasonable, provided
that at least ten (10) days prior to any such settlement, written notice of its
intention to settle is given to the Indemnifying Party.  If, pursuant to this
Section 9.1.8, the Indemnified Party so contests, defends, litigates or settles
a Third Party Claim, for which it is entitled to indemnification hereunder as
hereinabove provided, the Indemnified Party shall be reimbursed by the
Indemnifying Party for the reasonable attorneys' fees and other expenses of
defending, contesting, litigating and/or settling the Third Party Claim which
are incurred from time to time, forthwith following the presentation to the
Indemnifying Party of itemized bills for said attorneys' fees and other
expenses.

                 9.1.9   CLAIMS INVOLVING TAXES.  In the case of any proposed or
actual assessment of Tax liabilities for which a Parent Indemnitee is entitled
to indemnification from the Company as provided herein, Parent shall give notice
to the Company Securityholders, and shall contest such proposed or actual
assessment in the manner reasonably directed by the Company Securityholders (in
consultation with the Parent) through the administrative review or appeal
procedures available under the relevant Tax laws and regulations.  The Company
Securityholders shall bear all costs and expenses relating to any action
requested by the Company Securityholders to be taken by Parent under this
Section 9.1.9.  If the pursuit of such

                                       44
<PAGE>
 
administrative remedies by the Parent is unsuccessful, Parent shall be entitled
to indemnification for the Tax (and any penalties and interest) pursuant to
Section 9.1 hereof; provided however, that if within ten (10) days of receipt
                    -------- -------                                         
from the Parent of notice of its intention to do so, the Company Securityholders
shall notify the Parent of their desire to contest the proposed or assessed Tax
deficiency in the courts, they shall be entitled to do so at their expense
provided the Company Securityholders pay the deficiency and any penalties and
interest if required in order to seek judicial relief.  The Parent shall
cooperate with the Company for such purposes but shall be entitled to
reimbursement for any out-of-pocket expenses incurred by the Parent in doing so.
For purposes of this Section 9.1.9, the Company Securityholders shall select a
Company Securityholder representative to act on their behalf who shall serve as
a liaison between Parent and the Company Securityholders with respect to all
matters arising under or related to this Section 9.1.9.

                 9.1.10  COOPERATION.  Subject to the provisions of Section
9.1.8, the Indemnified Party shall have the right, at its own expense, to
participate in the defense of any Third Party Claim, and if said right is
exercised, the parties shall cooperate in the investigation and defense of said
Third Party Claim.

                 9.1.11  SUBROGATION.  The Indemnifying Party shall not be
entitled to require that any action be brought against any other Person before
action is brought against it hereunder by the Indemnified Party and shall not be
subrogated to any right of action until it has paid in full or successfully
settled or defended against the Third Party Claim for which indemnification is
sought.

                 9.1.12  INDEMNIFICATION NET OF BENEFITS.  The amount of any
recovery by an Indemnified Party pursuant to this Section 9.1 shall be net of
any insurance benefits actually received by such Indemnified Party (but not to
the extent such benefits are repaid through retrospective premium adjustments or
otherwise) or any foreign federal, state and/or local tax benefits actually
received by such Indemnified Party as a result of the state of facts which
entitled the Indemnified Party to recover from the Indemnifying Party pursuant
to this Section 9.1.  Notwithstanding the foregoing, any increase or decrease
in the basis of any assets or stock of the Parent or any of its Subsidiaries
shall not be considered to give rise to a tax benefit for purposes of this
Section 9.1.12.

          9.2    REGISTRATION STATEMENT FILING.

                 9.2.1   As promptly as reasonably practicable following the
Closing, Parent shall file with the Securities and Exchange Commission (the
"Commission") a registration statement (the "Registration Statement") on any
appropriate form under the Securities Act of 1933, as amended (the "Securities
Act") with respect to the offering and sale or other disposition of the Merger
Shares to be issued in the Merger.  Parent agrees to use all reasonable efforts
to cause the Registration Statement to become effective as soon as reasonably
practicable following its filing.  The Principal Stockholders agree to cooperate
with and provide assistance to Parent

                                       45
<PAGE>
 
in connection with the registration and sale of the Merger Shares.
Notwithstanding the foregoing, the Company and the Principal Stockholders
acknowledge and agree that Parent shall have no obligation to name in the
Registration Statement any Company Securityholder as a selling stockholder at
the time of the original filing; provided, that, Parent files a post-effective
amendment or amendments which become effective on or prior to the second
anniversary of the Closing Date including (as of such date) all Company
Securityholders as selling stockholders and thus allowing each Company
Securityholder an opportunity to effect sales of Merger Shares pursuant to the
Registration Statement at least as of such time.

                 9.2.2   Parent agrees that, subject to the provisions of the
last sentence of Section 9.2.1, it will (i) prepare and file with the
Commission, any amendments or supplements to the Registration Statement or
prospectus which is a part thereof which may be necessary to keep the
Registration Statement effective and to comply with the provisions of the
Securities Act with respect to the offer of the Merger Shares covered by the
Registration Statement for a period of three (3) years from the effective date
of the Registration Statement; (ii) prepare and promptly file with the
Commission and promptly notify the Company Securityholders of the filing of such
amendment or supplement to the Registration Statement or prospectus as may be
necessary to correct any statement therein or omission therefrom if, at any time
when a prospectus relating to the Merger Shares is required to be delivered
under the Securities Act, any event with respect to Parent shall have occurred
as a result of which any prospectus would include an untrue statement of
material fact or omit to state any material fact necessary to make the
statements therein not misleading; (iii) in case the Company Securityholders are
required to deliver a prospectus, prepare promptly such amendment or amendments
to the Registration Statement and such prospectus or prospectuses as may be
necessary to permit compliance with the requirements of Section 10(a)(3) of the
Securities Act; (iv) advise the Company Securityholders promptly after Parent
shall receive notice or obtain knowledge of the issuance of any stop order by
the Commission suspending the effectiveness of the Registration Statement or
amendment thereto or of the initiation or threatening of any proceedings for
that purpose, and promptly use its commercially reasonable efforts to prevent
the issuance of any stop order or to obtain its withdrawal if such stop order
should be issued; (v) use its best efforts to qualify the Merger Shares for sale
under the securities or "blue Sky" laws of such states within the United States
as the Securityholders may reasonably designate; and (vi) furnish to the Company
Securityholders, as soon as available, copies of the Registration Statement and
each preliminary and final prospectus, or supplement or amendment required to be
prepared with respect thereto, all in such quantities as they may from time to
time reasonably request.

                 9.2.3   Parent shall pay all expenses (the "Registration
Expenses") incurred by Parent incident to the registration of the Merger Shares
under this Section 9.2, including, without limitation, all registration and
filing fees, all fees and expenses of complying with securities or blue sky
laws, all word processing, duplicating and printing expenses, messenger and
delivery expenses, the fees and disbursements of counsel for Parent and of its
independent public accountants, premiums and other costs of policies of
insurance purchased by

                                       46
<PAGE>
 
Parent at its option against liabilities arising out of the public offering of
such Merger Shares.  With respect to sales of Merger Shares, the Company
Securityholders shall pay all underwriting discounts and commissions and fees of
underwriters, selling brokers, dealer managers or similar securities industry
professionals relating to the distribution of the Merger Shares, the fees and
disbursements of counsel retained by the Company Securityholders and transfer
taxes, if any.

                 9.2.4   Parent agrees to indemnify and hold harmless, to the
full extent permitted by law, each Company Securityholder, its officers,
directors and employees and each person who controls such Company Securityholder
(within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and expenses caused by any untrue or alleged untrue statement of a
material fact contained in the Registration Statement or prospectus or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as the same are caused by or contained in any information
furnished in writing to the Parent by such Company Securityholder expressly for
use therein. Promptly after receipt by a Company Securityholder under this
Section 9.2.4 of notice of the commencement of any action (including any
governmental action), such Company Securityholder will, if a claim in respect
thereof is to be made against the Parent under this Section 9.2.4, notify Parent
in writing of the commencement thereof and Parent shall have the right to
participate in, and, to the extent Parent so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with counsel
mutually satisfactory to the parties; provided, however, that a Company
Securityholder shall have the right to retain its own counsel, with the fees and
expenses to be paid by Parent, if representation of such Company Securityholder
by the counsel retained by Parent would be inappropriate due to actual or
potential differing interests between such Company Securityholder and any other
party represented by such counsel in such proceeding. The failure to notify
Parent within a reasonable time of the commencement of any such action, if
prejudicial to its ability to defend such action, shall relieve Parent of any
liability to the Company Securityholder under this Section 9.2.4 but the
omission so to notify Parent will not relieve it of any liability that it may
have to any Company Securityholder otherwise than under this Section 9.2.4.

          9.3    LISTING OF ADDITIONAL SHARES ON NASDAQ.  As promptly as
reasonably practicable following the Closing, the Parent shall prepare and
submit to the National Association of Securities Dealers an Additional Listing
Application and all other documents and fees necessary to cause the Merger
Shares to be listed on the NMS.

          9.4    COMPANY FAILURE TO CLOSE.  In the event this Agreement is
terminated pursuant to Article 10 as a result of the failure of any condition
set forth in Section 8.1.1 and the Company or the Company Securityholders enter
into an agreement to effect a sale of substantially all of the assets, or a
majority of the voting securities of the Company (collectively, the "Proposed
Transaction"), within six months from the date of termination under Article 10
hereof to a party who had or on whose behalf there had been discussions relating
to a Proposed Transaction made with the Company, a Principal Stockholder or
their agents or representatives regarding the Proposed Transaction during the
period from November 1, 1995 and ending on

                                       47

the date of the meeting, or written consent set forth in Section 6.3 hereof, the
Company shall pay to Parent all costs incurred by Parent (not to exceed
$250,000) in connection with the negotiation, execution and consummation of this
Agreement plus an additional $250,000.

                                  ----------- 

     This Agreement may be terminated and the Merger may be abandoned at any
time prior to the Effective Time:

          10.1   MATERIAL BREACH.  By a non-breaching party, in the event of a
material breach of any representation, warranty, condition or agreement
contained in this Agreement that is not cured within 30 days of the time that
written notice of such breach is received by such other party from the party
giving notice;

          10.2   CONSUMMATION OF MERGER.  If the Merger shall not have been
consummated on or before May 31, 1996; provided, in the case of a termination
pursuant to this Section 1.0.2, the terminating party shall not have materially
breached its obligations hereunder in any manner that shall have contributed to
the failure to consummate the Merger by such date.

          10.3   DUE DILIGENCE.  In the event that the Parent's due diligence
investigation of the Company and its Subsidiaries conducted between the date
hereof and the Closing Date, related to all aspects of the business of the
Company and its Subsidiaries, is not completed to the satisfaction of Parent in
its sole discretion, the Parent may elect to the terminate this Agreement by
giving written notice of termination to the Company within seven (7) days of the
conclusion of such due diligence investigation.

          10.4   MUTUAL CONSENT.  By mutual written consent of the Parent and
the Company authorized by their respective Boards of Directors.

          10.5   EFFECT OF TERMINATION.  In the event of termination of this
Agreement and abandonment of the Merger pursuant to this Article 1.0, no party
hereto (or any of its Affiliates) shall have any liability or further obligation
to any other party to this Agreement, except that if termination of this
Agreement shall be judicially determined to have been caused by willful breach
of this Agreement, then, in addition to other remedies at law or equity for
breach of this Agreement, the party so found to have willfully breached this
Agreement shall indemnify the other parties for their respective costs, fees and
expenses of their counsel, accountants and other experts and advisors as well as
fees and expenses incident to negotiation, preparation and execution of this
Agreement and related documentation and their stockholders' meetings and
consents.

                          CHOICE OF LAW; ARBITRATION
                          --------------------------

     The internal laws of the State of California, United States of America,
applicable to contracts entered into and wholly to be performed in California by
California residents, without reference to any principles concerning conflicts
of law, shall govern the validity of this Agreement, the construction of its
terms and the interpretation of the rights and duties of the parties hereunder;
provided, however, that this Section and the parties' rights under this Section
shall be governed by and construed in accordance with the Federal Arbitration
Act, 9 U.S.C. (S) 1 et. sec.  Any controversy or claim arising out of or
relating to this Agreement, or the breach thereof, shall be settled by the
following procedures:  Either party may send the other written notice
identifying the matter in dispute and involving the procedures of this Section.
Within fourteen (14) days after such written notice is given, one or more
principals of each party shall meet at a mutually agreeable location in San
Francisco, California, for the purpose of determining whether they can resolve
the dispute themselves by written agreement, and, if not, whether they can agree
upon a third-party impartial arbitrator (the "Arbitrator") to whom to submit the
matter in dispute for final and binding arbitration.  If the parties fail to
resolve the dispute by written agreement or to agree on the Arbitrator within a
twenty-one (21) day period, either party may make written application to the
Judicial Arbitration and Mediation Services ("JAMS"), San Francisco, California
for the appointment of a single Arbitrator to resolve the dispute by arbitration
and at the request of JAMS, the parties shall meet with JAMS at its offices or
confer with JAMS by telephone within ten (10) calendar days of such request to
discuss the dispute and the qualifications and experience which each party
respectively believes the Arbitrator should have; provided, however, the
selection of the Arbitrator shall be the exclusive decision of JAMS and shall be
made within thirty (30) days of the written application to JAMS.  Within 30 days
of the selection of the Arbitrator, the parties shall meet in San Francisco,
California with such Arbitrator at a place and time designated by the Arbitrator
after consultation with the parties and present their respective positions on
the dispute.  Each party shall have no longer than one day to present its
position, the entire proceeding before the Arbitrator shall be on no more than
three consecutive days, and the award shall be made in writing no more than 30
days following the end of the proceeding.  Such award shall be a final and
binding determination of the dispute and shall be fully enforceable as an
arbitration award in any court having jurisdiction and venue over the parties.
The prevailing party (as determined by the Arbitrator) shall in addition be
awarded by the Arbitrator such party's own attorneys' fees and expenses in
connection with such proceeding.  The non-prevailing party (as determined by the
Arbitrator,) shall pay the Arbitrator's fees and expenses.

                                      TO
                     AGREEMENT AND PLAN OF REORGANIZATION


     Amendment No. 1 to Agreement and Plan of Reorganization (the "Amendment No.
1") dated this April 11, 1996, by and among the Principal Stockholders,
Veterinary Centers of America, Inc., a Delaware corporation ("Parent"), PRI
Merger Company, a Delaware corporation ("MergerCo") and Pets Rx, Inc., a
Delaware corporation (the "Company").


                                R E C I T A L S
                                ---------------

     A.   Parent, MergerCo and the Company have entered into that certain
Agreement and Plan of Reorganization (the "Merger Agreement") dated February 27,
1996 pursuant to which MergerCo shall merge with and into the Company (the
"Merger"), the separate existence of MergerCo shall cease and the Company shall
continue as the surviving corporation. Terms used herein without definition
shall have the meanings given those terms in the Merger Agreement.

     B.   Pursuant to Section 1.22 of the Merger Agreement, Merger Shares means
970,000 shares of Parent Common Stock minus the Reduction Shares.

     C.   Pursuant to Section 5.2 of the Merger Agreement, Parent represents and
warrants that when the execution and delivery of the Merger Agreement and each
of the Ancillary Agreements and the consummation of the transactions
contemplated by the Merger Agreement and the Ancillary Agreements are duly and
validly authorized by Parent's and MergerCo's Board of Directors, all corporate
proceedings will have been taken and no other corporate proceedings on the part
of Parent or MergerCo will be necessary to authorize the execution, delivery and
performance by Parent and MergerCo of the Merger Agreement and each of the
Ancillary Agreements.

     D.   Pursuant to Section 6.5 of the Merger Agreement, Parent shall take all
necessary or appropriate action to call a meeting of its Board of Directors
within fourteen days after the execution of the Merger Agreement to consider and
vote on the terms of the Merger and the execution of the Merger Agreement. Based
on subsequent discussions among the parties, Parent's obligations under Section
6.5 were extended until April 5, 1996.

     E.   Pursuant to Section 6.11, the Company shall deliver to Parent the
Disclosure Schedules by March 19, 1996. Based on subsequent discussions among
the parties, the Company's obligation to deliver the Disclosure Schedules under
Section 6.11 was extended until April 5, 1996.
<PAGE>
 
     F.   Pursuant to Section 8.4 of the Merger Agreement, Parent shall have
completed and approved to its sole satisfaction customary business and legal due
diligence with respect to the Company, its Subsidiaries and their respective
businesses and, in the event the diligence is not satisfactory to Parent, Parent
must deliver notice thereof to the Company within four (4) business days
following receipt of the Company's audited financial statements for the year
ended December 31, 1995.

     G.   The parties desire to modify the terms of Sections 1.22, 5.2, 6.5,
6.11 and 8.4 and such other terms of the Merger Agreement as set forth below.

                               A G R E E M E N T
                               -----------------

     NOW THEREFORE, in consideration of the foregoing premises and mutual
covenants herein provided, the parties agree as follows:

     1.   Section 1.22 of the Merger Agreement is hereby amended to read in its
entirety as follows:

          "MERGER SHARES" shall mean 850,000 shares of Parent Common Stock minus
          the Reduction Shares, which Merger Shares are to be exchanged for the
          Company Common Stock and the Company Preferred Stock pursuant to this
          Agreement. Notwithstanding the foregoing, in the event the average
          closing sale prices of the Parent Common Stock on the Nasdaq National
          Market (as reported by the Wall Street Journal, or if not so reported
          as reported by another authoritative source) over the five (5) trading
          day period ending on (and including) one day prior to the Closing Date
          (the "Average Price") is between $21.169 and $18.55 (inclusive), the
          Merger Shares shall be determined by dividing $17,993,500 by the
          Average Price less the Reduction Shares. If the Average Price is less
          than $18.55, the Merger Shares shall equal 970,000 shares of Parent
          Common Stock less the Reduction Shares.

     2.   The second sentence of Section 5.2 of the Merger Agreement is hereby
amended to read in its entirety as follows:

          "The execution and delivery of this Agreement and each of the
          Ancillary Agreements and the consummation of the transactions
          contemplated hereby and thereby have been duly and validly authorized
          by Parent's and MergerCo's Board of Directors all corporate
          proceedings have been taken and no other corporate proceedings on the
          part of Parent or MergerCo are necessary to authorize the execution,
          delivery and performance by Parent and MergerCo of this Agreement and
          each of the Ancillary Agreements."

                                       2
<PAGE>
 
     3.   Parent has delivered notice of the satisfaction of its obligation set
forth in Section 6.5 of the Merger Agreement. This Paragraph 3 shall supersede
the obligations contained in Section 6.5 of the Merger Agreement and shall
satisfy the condition to closing set forth in Section 8.12 of the Merger
Agreement.

     4.   The Company has delivered the Disclosure Schedules in satisfaction of
its obligation set forth in Section 6.11 of the Merger Agreement. The
representations and warranties set forth in Articles 4 and 4A of the Merger
Agreement shall be effective as of April 11, 1996. The parties agree that the
Company's obligation to deliver the Disclosure Schedules under Section 6.11 of
the Merger Agreement was extended to April 11, 1996.

     5.   Parent has completed its business and legal due diligence and such
diligence is satisfactory to Parent. This Paragraph 5 shall satisfy the
condition to closing set forth in Section 8.4 of the Merger Agreement.

     6.   The parties further agree that their respective filings under the Hart
Scott Act shall be made as of April 12, 1996.

     7.   Except as amended by this Amendment No. 1, the Agreement and Plan of
Reorganization will continue unmodified and in full force and effect.

     8.   This Amendment No. 1 may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

                                       3

Stockholder" and collectively, the "Principal Stockholders").

failure to consummate the Merger by such date. The parties to the Merger 
Agreement wish to modify the terms of Section 10.2 of the Merger Agreement to 
extend the Expiration Date to June 20, 1996.

a Delaware corporation ("MergerCo"), Pets' Rx. Inc., a Delaware corporation (the
"Company"), and the persons identified on Schedule A hereto (each, a "Principal
                                          ---------- 
Stockholder" and collectively, the "Principal Stockholders").

     A.   Parent, MergerCo, the Company and the persons identified on Schedule A
thereto have entered into that certain Agreement and Plan of Reorganization, 
dated February 27, 1996, as amended by Amendment No. 1 to Agreement and Plan of 
Reorganization dated April 11, 1996 and by Amendment No. 2 to Agreement and Plan

appropriate form under the Securities Act of 1933, as amended (the "Securities 
Act"), with respect to the offering and sale or other disposition of the Merger 
Shares to be issued in the Merger. Parent agrees to use all reasonable efforts 
to cause the Registration Statement to become effective as soon as reasonably 
practicable following its filing. The Principal Stockholders agree to cooperate

effective amendments or separate registration statement to become effective on

Principal Stockholder an opportunity to effect sale of Merger Shares after such 
second anniversary and (b) with respect to all Company Securityholders other 
than Principal Stockholders (the "Minority Securityholders"), Parent shall have 
no obligation to name in the Registration Statement any Minority Securityholder 
as a selling stockholder at the time of the original filing; provided, that:

     (i)   Parent files a post-effective amendment or amendments to the 
     Registration Statement or, if necessary, a separate registration statement,
     and uses all reasonable efforts to cause such post effective amendments or
     separate registration statement to become effective on or prior to January
     30, 1997 including (as of such date) all Minority Securityholders as
     selling stockholders so as to allow each Minority Securityholder an
     opportunity to effect sales of 33.33% of those Merger Shares received by
     such Minority Securityholder and not placed in escrow pursuant to the terms
     of the Merger Agreement and the Escrow Instrument;

     (ii)  Parent files a post-effective amendment or amendments to the 
     Registration Statement or, if necessary, a separate registration statement,
     and uses all reasonable efforts to cause such post effective amendments or
     separate registration statement to become effective on or prior to April
     30, 1997 including (as of such date) all Minority Securityholders as
     selling stockholders so as to allow each Minority Securityholder an
     opportunity to effect sales of an additional 33.33% of those Merger Shares
     (not otherwise included in the post-effective amendment referred to in
     clause (i) above) received by such Minority Securityholder and not placed
     in escrow pursuant to the terms of the Merger Agreement and the Escrow
     Instrument; and

     (iii) Parent files a post-effective amendment or amendments to the 
     Registration Statement or, if necessary, a separate registration statement,
     and uses all reasonable efforts to cause such post effective amendments or
     separate registration statement to become effective on or prior to July 30,
     1997 including (as of such date) all Minority
