THIS AGREEMENT (this “Agreement”) is made and entered into as of the 31st day of
December, 2008, by and between PET DRX CORPORATION, a Delaware corporation (the
“Company”), and STEVEN T. JOHNSON (“Executive”).

BACKGROUND

Executive shall be employed by the Company through December 31, 2008, pursuant
to that certain employment agreement dated October 19, 2007 (the “Employment
Agreement”). Effective December 31, 2008, Executive hereby resigns as an
employee, officer, director and from all other positions he holds with Company
and its subsidiaries, Executive’s employment is hereby terminated as of
December 31, 2008, and the Company accepts such resignation. In connection with
Executive’s termination of employment and the execution of this Agreement, the
Company agrees to provide Executive with the payments and benefits described in
Exhibit A to this Agreement, and the parties desire that Executive shall serve
as a consultant to the Company for three (3) months, commencing January 2, 2009,
pursuant to the Consulting Agreement attached as Exhibit B to this Agreement.

AGREEMENT

In consideration for the mutual promises contained in this Agreement, the
Company and Executive agree as follows:

1.   Employment Termination.

(a) General Terms. The Company and Executive agree that:

(1) Executive shall cease to be an employee, officer, and director of, and to
hold any positions with, the Company as of December 31, 2008;

(2) Executive’s last day of employment with the Company shall be December 31,
2008, and on that date, he shall have incurred a “separation from service”
within the meaning of Section 409A of the Internal Revenue Code of 1986, as
amended (the “Termination Date”);

(3) Executive hereby resigns, effective as of December 31, 2008, from any and
all titles and positions with the Company. Executive agrees to tender and
memorialize his resignation from any and all such positions in any other manner
and form as the Company may reasonably request; and

(4) This Agreement was first delivered to Executive on December 29, 2008
(“Delivery Date”).

(b) Satisfaction of Obligations. The payments, benefits and other consideration
provided by the Company under this Agreement are in full and final satisfaction
of all obligations that the Company has to Executive, except as provided in
Section 4(a) hereof. Without limiting the foregoing, these payments and benefits
replace any and all obligations of the Company under any and all letters,
agreements, understandings, plans and policies, relating to Executive’s
employment and severance, except as provided in Section 4(a) hereof. Executive
agrees that the payments and benefits described in Exhibit A and the Consulting
Agreement attached as Exhibit B are adequate consideration for (i) the
agreements he makes in this Agreement, and (ii) the releases he gives pursuant
to this Agreement.

(c) No Other Payments or Benefits. Executive shall not be eligible for, and he
will not receive, any payments or benefits from the Company, or under any plan,
agreement, or arrangement in which Executive or the Company are a party or
participate which are not expressly set forth in this Agreement.

2.   Payments and Benefits Following Executive’s Severance Date.

(a) General Conditions. The Company shall provide to Executive the payments and
benefits described in Exhibit A to this Agreement and under the Consulting
Agreement when required by Exhibit A and the Consulting Agreement, respectively.
However, for these payments and benefits to be due, Executive must have signed,
dated and returned this Agreement and the Consulting Agreement to the Company on
or within 21 days after the Delivery Date (even if Executive has continued to
negotiate the terms of this Agreement with the Company after the Delivery Date),
Executive must not revoke this Agreement, the Company must not revoke this
Agreement, and the revocation period described in Section 9 must have expired.
This Agreement shall become effective as of the latest of the date of execution
and delivery of the Consulting Agreement, the day after expiration of the
revocation period, or January 2, 2009 (the “Effective Date”). Notwithstanding
any other provision of this Agreement, Executive’s termination of employment
will become effective December 31, 2008, regardless of the general effective
date of this Agreement and regardless of whether Executive revokes this
Agreement.

(b) Taxes. Executive is solely responsible for paying any and all taxes he owes
on amounts he receives or that are paid on his behalf under the terms of this
Agreement. The preceding provision does not, and shall not be construed to, make
Executive responsible for taxes that are imposed on any person or entity other
than himself. The Company will withhold all taxes that it determines are legally
required to be withheld.

3.   Cooperation.

(a) Transition. Executive shall cooperate with the Company in ensuring an
orderly transition of matters handled by Executive. Executive shall sign any
documents and do anything that is reasonably necessary in the future to
implement his agreements in this Agreement.

(b) Nondisparagement. Executive agrees that he shall not, directly or
indirectly, in any capacity or manner, make, cause, encourage or assist to be
made any statements, comments or remarks, whether oral, in writing or
electronically transmitted, which might reasonably be considered to be
derogatory, defamatory or critical of, or negative towards, or to malign, harm,
defame, disparage or damage the reputation of the Company or any of the other
Released Parties (as defined below). This subsection shall not apply to any
communications that are (i) intended to comply with the requirements and
policies of any federal or state agency, (ii) intended to cooperate with any
investigation or request for information from any state or federal government
agency, or (iii) made in connection with any judicial or administrative
proceeding. Executive agrees that he will not make any statements about the
Company or any of the other Released Parties to the press (including without
limitation any newspaper, magazine, radio station or television station) without
the prior written consent of the Chairman of the Board of Directors of the
Company.

(c) Cooperation as a Witness. Executive shall cooperate with the Company as a
witness in all matters about which he has knowledge as a result of his prior
positions with the Company if the Company requests his testimony. To the extent
practicable and within the control of the Company, the Company will use
reasonable efforts to schedule the timing of his participation in any such
witness activities in a reasonable manner to take into account his then-current
employment, and will pay the reasonable documented out-of-pocket expenses that
the Company pre-approves and that Executive incurs for travel required by the
Company with respect to those activities.

4.   General Release of Claims by Executive.

(a) Release. As a material inducement for the Company to enter into this
Agreement, Executive hereby forever, irrevocably and unconditionally, releases
and discharges the Company and the other Released Parties (as defined below)
from any and all charges, claims, liabilities, agreements, damages, causes of
action, suits, costs, losses, debts and expenses (including attorneys’ fees and
costs actually incurred) of any nature whatsoever, known or unknown, which he
now has, or claims to have, or which Executive at any time had, or claimed to
have, or which Executive at any time hereafter may have, or claim to have,
against the Company, in each case as to acts or omissions occurring up to and
including the day before the Effective Date, including, without limitation, any
claim of breach of fiduciary duty, rights arising out of alleged violations of
any contracts, express or implied, any covenant of good faith and fair dealing,
express or implied, or any tort, or any legal restrictions on the Company’s
right to terminate employees, or any federal, state or other governmental
statute, regulation, or ordinance (all such matters hereby released,
collectively referred to as “Claims”).

This release will not apply to any claim for payments or benefits Executive may
have under the terms of this Agreement, any rights he may have with respect to
vested stock options or any rights to the “Accrued Obligations” as defined in
the Employment Agreement.

(b) Released Parties. As used in this Agreement, the “Released Parties” are the
Company and all of its related companies, partnerships or joint ventures,
including but not limited to, direct and indirect parent and subsidiary
companies, and their predecessors and successors; and, with regard to each of
those entities, except for Executive, all of its past and present employees,
officers, directors, stockholders, owners, representatives, assigns, attorneys,
agents, insurers, employee benefit programs (and the trustees, administrators,
fiduciaries and insurers of these programs) and any other persons acting by,
through, under or in concert with any of the persons or entities listed in this
subsection. Executive understands that this release covers him and anyone who
might have a claim through him or because of him, such as a past, current or
future spouse, his family, heirs, executors, representatives, agents and their
successors and assigns.

(c) No Lawsuits. Executive has not filed or caused to be filed any lawsuit,
complaint or charge with respect to any Claim he is releasing in this Agreement.
Executive agrees never to institute, or participate in any action against any of
the Releasees with respect to any Claim released by this Agreement, except as
required by subpoena, court order, or other compulsory process and except that
he may participate in an investigation or proceeding conducted by an agency of
the United States government or of any state. Executive has not assigned or
transferred any Claim he is releasing, nor has he purported to do so.
Notwithstanding any language herein to the contrary, Executive understands that
nothing in this Release prohibits Executive from filing or pursuing a charge of
discrimination with the Equal Employment Opportunity Commission (“EEOC”) or a
claim with the National Labor Relations Board (“NLRB”); provided that, by
signing this Agreement, Executive agrees to waive and relinquish any personal or
monetary gain that would otherwise result from such EEOC or NLRB claim.

(d) Release of Age Claims. Executive expressly and specifically waives any and
all rights or claims which he may have under the Age Discrimination in
Employment Act of 1967, 29 U.S.C. Section 621 et seq. (“ADEA”). Executive
acknowledges that this waiver is knowingly and voluntarily made and specifically
agrees that: (i) this waiver is written in a manner that he understands;
(ii) this waiver specifically relates to rights and claims under the ADEA;
(iii) he does not waive any rights or claims that may arise after the date he
signs this Agreement; (iv) he is waiving these rights or claims in exchange for
substantial consideration in excess of anything of value to which he is
otherwise entitled to receive; (v) he has been advised in writing, and given the
opportunity, to consult with an attorney before signing this Agreement; (vi) he
has been given a period of 21 days to review this Agreement; and (viii) after
Executive has signed this Agreement, he or the Company may revoke this Agreement
by providing written notice as provided in Section 9 hereof within 7 days
following his execution of the Agreement or if later by January 1, 2009.
Notwithstanding the foregoing, Executive’s termination of employment at December
31, 2008 shall be unaffected by his revocation of this Agreement. Executive
specifically agrees that the 21-day period that he has to review this Agreement
(including this release) and to consult an attorney began to run on the date he
executed the Amendment, and that any changes made since that date have not
extended or restarted that 21-day period.

5.   Consequences of Violating Executive’s Agreements or Breaching Executive’s
Release.

Executive understands that his agreements in Sections 3 and 4 and the releases
provided in this Agreement are especially important reasons why the Company
offered Executive the payments and benefits described in this Agreement.
Therefore, Executive agrees that if he breaches any of those agreements or the
releases, then, along with all other rights and remedies available to the
Company and their affiliates at law or in equity, the Company also can stop all
of the payments and benefits under this Agreement and the Consulting Agreement
to Executive immediately and can recover from Executive any payments and
benefits that he already received. Executive agrees that, in the event of his
breach of any agreement, any release or any other terms of this Agreement, the
Company, in addition to all other rights and remedies available to it at law or
in equity, may recover damages from Executive, and will be entitled to an
injunction restraining Executive from breaching his agreements, the releases or
any other terms of this Agreement. Executive also agrees to pay, promptly upon
demand, but in no event later than thirty (30) days after a judicial
determination that the Company has breached this Agreement, the reasonable
attorneys’ fees and related damages the Company may incur as a result of
Executive breaching his agreements, a release or any other term(s) of this
Agreement or if any representation Executive made in this Agreement was false
when made. Executive understands that no provision in this Agreement is to be
construed as a waiver or prohibition against the Company pursuing any other
legal or equitable remedy for a breach of this Agreement. Executive understands,
however, that this section will not apply to any challenge of the validity of
the release given under the ADEA.

6.   Consequences of Breach by the Company.

The Company agrees that, in the event of its breach of this Agreement,
Executive, in addition to all other rights and remedies available to him at law
or in equity, may recover damages from the Company. The Company also agrees to
pay, promptly upon demand, but in no event later than thirty (30) days after a
judicial determination that the Company has breached this Agreement, the
reasonable attorneys’ fees and related damages that Executive may incur as a
result of the Company breaching this Agreement.

7. Nondisparagement by the Company. The Company agrees that the Company will
provide one directive to the current members of the Boards of Directors and
executive officers of the Company to not make any statements which are
derogatory to Executive. This directive shall not apply to any communications
that are (a) between the Company and its auditors, (b) intended to comply with
the requirements and policies of any federal or state agency, (c) intended to
cooperate with any investigation or request for information from any state or
federal government agency, (d) made in connection with any judicial or
administrative proceeding, or (e) between members of the Boards of Directors
and/or executive officers of the Company in the course of operating the
Company’s business, provided the communications are not published to third
parties. Once the Company has given the one directive provided for in this
Section, its obligations under this Section are complete, and the Company will
not be liable under this Section if any directors or officers do not comply with
the directive.

8.   Miscellaneous Provisions.

(a) Binding Agreement. This Agreement is final and binding. Executive has
carefully read and fully understands all of the provisions of this Agreement.

(b) Entire Agreement. This Agreement forms the entire agreement between the
Company and Executive and supersede all other agreements, understandings, plans
or arrangements relating to the subject matter hereof, except that (1) the
provisions of Sections 6 through 12 of the Employment Agreement shall survive
Executive’s termination of employment pursuant to Section 12(d) thereof, and
(2) this Agreement does not supersede or affect the Confidentiality and
Assignment of Creative Works Agreement between XLNT Veterinary Care, Inc. and
Executive dated October 19, 2007. Executive acknowledges that the Company has
made no representations or promises to Executive, written or oral, other than
those in this Agreement.

(c) Amendment.  This Agreement may not be modified, amended, supplemented or
terminated except by a written instrument executed by the parties hereto.

(d) Assignment. The rights and obligations of the Company under this Agreement
shall inure to the benefit of the Company’s successors and assigns. This
Agreement may be assigned by the Company to an affiliate, to any legal successor
to all or a portion of the business of the Company or an affiliate, or to an
entity which purchases assets from either of the Company or an affiliate. In the
event the Company assigns this Agreement as permitted by this Agreement, “the
Company” as defined herein will refer to the assignee. Executive may not assign
this Agreement.

(e) Waiver.  The waiver by the Company of any breach of this Agreement by any
party shall not be effective unless in writing, and no such waiver shall
constitute the waiver of the same or another breach on a subsequent occasion.

(f) Arbitration. In the event of any dispute under this Agreement, other than a
dispute pursuant to Section 8(b) that relates to Section 6 through 12 of the
Employment Agreement, the Confidentiality Agreement, or the Consulting
Agreement, the parties shall be required to have the dispute resolved by binding
arbitration in the city in which the headquarters of the Company is located in
accordance with the commercial arbitration rules then in effect of the American

arbitration provision shall be specifically enforceable. The fees of the
American Arbitration Association and the arbitrators shall be shared equally by
the parties; provided, however, that the party that materially prevails in any

for all of such party’s fees and costs (including, without limitation, the fees
of the American Arbitration Association and the arbitrators and reasonable
attorneys’ fees and expenses) that are incurred at any time, and such fees and
costs shall be reimbursed promptly following submission of proof the expenses
but not later of March 15 of the year following year in which the judgment on

be used in construing it. Executive acknowledges that this Agreement is not an
admission of guilt or wrongdoing by the Company.

(i) Blue Penciling. If any court or arbitrator determines that any of the
provisions contained in this Agreement, or any part of it, are unenforceable
because of the length of any period of time, the size of any area or the scope
of activities contained in those provision(s), then that period of time, area or
scope will be considered to be adjusted to a period of time, area or scope which
would cure that invalidity, and those provisions in their revised form will then
be enforced to the maximum extent permitted by applicable law.

(j) Severability. Each of the covenants and agreements hereinabove contained
shall be deemed separate, severable and independent covenants, and in the event
that any covenant shall be declared invalid by any court of competent
jurisdiction, such invalidity shall not in any manner affect or impair the

any other covenant contained herein.

(k) Counterparts. This Agreement may be signed in counterparts, and the signed
counterparts will form a single agreement.

CONSULTING AGREEMENT

CONSULTING AGREEMENT

THIS AGREEMENT (this “Agreement”) is made effective as of the 2nd day of
January, 2009 (the “Effective Date”), by and between PET DRX CORPORATION, a
Delaware Corporation (“Company”), and STEVEN T. JOHNSON (the “Contractor”).

BACKGROUND

The Contractor was employed by the Company through December 31, 2008 (the
“Severance Date”), and was a party to that certain employment agreement dated
October 19, 2007 with the Company (the “Employment Agreement”). Effective
December 31, 2008, the Contractor voluntarily resigned as an employee, officer,
director and from all other positions he held with the Company, including his
position as a member of the Board of Directors of the Company. The Company has
accepted the Contractor’s resignation. The Company and the Contractor now desire
to enter into an agreement pursuant to which the Contractor will provide
services to the Company from and after the Effective Date, upon the terms set
forth below.

AGREEMENT

In consideration of the mutual promises contained in this Agreement, the Company
and the Contractor agree as follows:

1. Terms and Conditions of Engagement.

(a) Engagement. The Contractor shall perform such consulting and advisory
services for the Company as the Company may require from time to time, including
without limitation assisting with transition matters that relate to his prior
duties with the Company. Consultant shall report to the Chairman of the Board of
Directors of the Company and to the Board of Directors of the Company or to such
person(s) as the Company shall designate. The parties acknowledge that Executive
has incurred a “separation from service” within the meaning of Section 409 of
the Internal Revenue Code of 1986, as amended, and accordingly, that the parties
reasonably anticipate that the level of bona fide services that the Contractor
will perform will permanently decrease to less than twenty percent (20%) of the
average level of bona fide services performed over his preceding period of
employment with the Company.

(b) Contractor Relationship. The Contractor is an independent contractor to the
Company, not an employee of the Company. The Contractor is not an agent of the
Company and shall have no right to bind the Company. The Company will report all
payments to be made hereunder on Forms 1099 as payments to the Contractor for
independent contracting services, and will not report any payments on Form W-2
to the Contractor. The Company will not withhold taxes on any payments pursuant
to this Agreement, and the Contractor shall be solely responsible for paying any
and all taxes he owes on amounts he receives under this Agreement. The
Contractor shall not be treated for any purposes as an employee of the Company
and shall not be entitled to participate in any employee benefits plans or
programs of the Company. This is a personal services contract for the services
of the Contractor. The Contractor cannot satisfy the terms and conditions of
this Agreement by making anyone else available to perform his services. The
Contractor shall devote sufficient business time and efforts to the performance
of services for the Company to complete the services within the time frames for
completion established by the Company. The Contractor shall use his best efforts
in such endeavors. The Contractor shall also perform his services with a level
of care, skill, and diligence that a prudent professional acting in a like
capacity and familiar with such matters would use.

2. Compensation.

(a) Fees. The Company shall pay to the Contractor $20,000 for his services
hereunder for each month of the Term, which shall be paid monthly, in arrears as
of the last business day of the month in which the services are performed,
(i.e., January 30, 2009, February 27, 2009, and March 31, 2009).

(b) Expenses. The Contractor shall be entitled to be reimbursed in accordance
with the policies of the Company, as adopted and amended from time to time, for
all reasonable and necessary expenses and business travel incurred by the
Contractor in connection with the performance of services hereunder; provided,
however, the Contractor shall, as a condition of such reimbursement, submit
verification of the nature and amount of such expenses in accordance with the
reimbursement policies from time to time adopted by the Company. Notwithstanding
the foregoing, for any expenses that exceed $500, the Contractor must obtain
advance authorization from the Company.

3. Term, Termination and Termination Payments.

(a) Term. The Term of this Agreement (the “Term”) shall commence as of the
Effective Date (provided that the Contractor does not, and the Company does not,
revoke the Separation Agreement between the Company and the Contractor dated as
of December 31, 2008 (the “Separation Agreement”) within the revocation period
provided therein) and will run through March 31, 2009 following the Effective
Date. This Agreement shall be null and void if the Contractor revokes the
Separation Agreement within the revocation period provided therein.

(b) Termination. This Agreement and the engagement of the Contractor by the
Company hereunder shall only be terminated: (i) as set forth in Section 3(a)
hereof; (ii) by the Contractor upon not less than thirty (30) days prior written
notice to the Company; (iii) by mutual agreement of the parties; or (iv) as a
result of the Contractor’s death. Notice of termination by any party shall be
given prior to termination in writing and shall specify the basis for
termination and the effective date of termination. The Contractor shall not be
entitled to any payments for services after termination of this Agreement.

4. Contracts or Other Agreements with Former Employer or Business.

The Contractor hereby represents and warrants that he is not subject to any
employment or consulting agreement or similar document with a former employer or
with any business as to which the Contractor’s engagement by the Company and
provision of services hereunder would be a breach. For that reason, the
Contractor hereby represents and warrants that he is not subject to any
agreement which prohibits the Contractor during a period of time which extends
through the Term from any of the following: (a) providing services for the
Company hereunder by this Agreement; (b) competing with, or in any way
participating in a business which includes the Company’s businesses;
(c) soliciting personnel of such former employer or other business to leave such
former employer’s employment or to leave such other business; or (d) soliciting
customers of such former employer or other business on behalf of another
business.

5. No Set Off.

The existence of any claim, demand, action or cause of action by the Contractor
against the Company, or any affiliate, whether predicated upon this Agreement or
otherwise, shall not constitute a defense to the enforcement by the Company of
any of its rights hereunder. The existence of any claim, demand, action or cause
of action by the Company or any affiliate against the Contractor, whether
predicated upon this Agreement or otherwise, shall not constitute a defense to
the enforcement by the Contractor of any of the Contractor’s rights hereunder.

6.   Notice.

All notices, requests, demands and other communications required hereunder shall
be in writing and shall be deemed to have been duly given (i) if delivered
personally, (ii) if sent by a reputable, nationally known overnight delivery

parties hereto relating to the subject matter hereof and supersedes all oral
agreements, and to the extent inconsistent with the terms hereof, all other
written agreements, except that (1) the provisions of Sections 6 through 12 of
the Employment Agreement shall survive the Contractor’s termination of
employment pursuant to Section 12(d) thereof, and (2) this Agreement does not
supersede or affect the Employee Confidentiality and Assignment of Creative
Works Agreement between XLNT Veterinary Care, Inc. and Executive dated

(b) Assignment. The rights and obligations of the Company under this Agreement
shall inure to the benefit of the Company successors and assigns. This Agreement

the assignee. The Contractor may not assign this Agreement.

party shall not be effective unless in writing, and no such waiver shall
constitute the waiver of the same or another breach on a subsequent occasion.

(d) Governing Law and Jurisdiction.  This Agreement shall be governed by and
construed in accordance with the internal laws of the State of Delaware.

(e) Arbitration. In the event of any dispute under this Agreement, other than a

Employment Agreement, the Confidentiality Agreement, or the Separation
Agreement, the parties shall be required to have the dispute resolved by binding
arbitration in the city in which the headquarters of the Company is located in
accordance with the commercial arbitration rules then in effect of the American
Arbitration Association. Any award entered by the arbitrator shall be final,

arbitration provision shall be specifically enforceable. The fees of the
American Arbitration Association and the arbitrators shall be shared equally by
the parties; provided, however, that the party that materially prevails in any
dispute arbitrated pursuant to this Agreement shall be entitled to reimbursement
for all of such party’s fees and costs (including, without limitation, the fees
of the American Arbitration Association and the arbitrators and reasonable
attorneys’ fees and expenses) that are incurred at any time, and such fees and
costs shall be reimbursed promptly following submission of proof the expenses
but not later of March 15 of the year following year in which the judgment on
the arbitration award becomes final.

are provided for convenience only and are not a part of this Agreement and shall
not be used in construing it.

(h) Severability.  Each of the covenants and agreements hereinabove contained

any other covenant contained herein.
