the Term Loan B Advances (other than in accordance with Section 2.6), or
reduction in the Maximum Line must be in an amount not less than $250,000 or an
integral multiple thereof. If the Borrowers reduce the Maximum Line to zero,
all Obligations shall be immediately due and payable. Any partial prepayments
of the Equipment Note (other than in accordance with Section 2.4), and any
partial prepayments of the Term Loan B Note (other than in accordance with Section 2.6),
shall be applied to principal payments due and owing in inverse order of their
maturities. Upon termination of the Credit Facility and payment and performance
of all Obligations, the Lender shall release or terminate the Security Interest
and the Security Documents to which the Borrowers are entitled by law.

 

Section 2.13           Termination, Line Reduction and
Prepayment Fees; Waiver of Termination, Prepayment and Line Reduction Fees.

 

(a)           Termination and Line
Reduction Fees.
If the Credit Facility is terminated for any reason as of a date other than the
Maturity Date, or the Borrowers reduce the Maximum Line, the Borrowers shall
pay the Lender a fee in an amount equal to the Prepayment Factor multiplied by
the Maximum Line (or the reduction, as the case may be).

 

23

 

(b)           Prepayment Fees. If the Equipment Note is prepaid for any
reason except in accordance with Section 2.4, the Borrowers shall pay to
the Lender a fee in an amount equal to the Prepayment Factor multiplied by the
amount prepaid. If the Term Loan B Note is prepaid for any reason except in
accordance with Section 2.6, the Borrowers shall pay to the Lender a fee
in an amount equal to one percent (1%) of the amount prepaid.

 

(c)           Waiver of Termination and
Line Reduction Fees. The
Borrowers will not be required to pay the termination or line reduction fees
otherwise due under this Section 2.13 if such termination or line
reduction is made (i) because of refinancing of the Borrowers by another
division of the Lender, (ii) within 60 days after any demand for payment
upon any Borrower in accordance with Section 2.11, or (iii) within 60
days after any Discretionary Reduction Date.

 

Section 2.14           Mandatory Prepayment. Without notice or demand, if the
outstanding principal balance of the Revolving Advances made to a Borrower
shall at any time exceed such Borrower’s Borrowing Base, such Borrower shall
immediately (or, to the extent such condition is a result of a Discretionary Reduction,
within 5 Business Days) prepay the Revolving Advances to the extent necessary
to eliminate such excess. Any payment received by the Lender under Section 2.12
may be applied to the Obligations, in such order and in such amounts as
the Lender, in its discretion, may from time to time determine; provided
that any prepayment under Section 2.12 which a Borrower designates as a
payment of the Revolving Advances, shall be applied to such Borrower’s
Revolving Advances; provided, further, that any prepayment under Section 2.12
which a Borrower designates as a partial prepayment of the Equipment Note or
the Term Loan B Note, shall be applied to principal installments of the
Equipment Note or the Term Loan B Note respectively, in inverse order of
maturity.

 

Section 2.15           Payment. All payments to the Lender shall be made in
immediately available funds and shall be applied to the Obligations upon
receipt by the Lender. The Lender may hold all payments not constituting
immediately available funds for three (3) days before applying them to the
Obligations. Notwithstanding anything in Section 2.2, each Borrower hereby
authorizes the Lender, in its discretion at any time or from time to time
without such Borrower’s request and even if the conditions set forth in Section 4.2
would not be satisfied, to make a Revolving Advance in an amount equal to the
portion of the Obligations from time to time due and payable.

 

Section 2.16           Payment on Non-Banking Days. Whenever any payment to be made
hereunder shall be stated to be due on a day which is not a Banking Day, such
payment may be made on the next succeeding Banking Day, and such extension
of time shall in such case be included in the computation of interest on the
Advances or the fees hereunder, as the case may be.

 

Section 2.17           Liability Records. The Lender may maintain from time
to time, at its discretion, liability records as to the Obligations. All
entries made on any such record shall be presumed correct until a Borrower
establishes the contrary. Upon the Lender’s demand, each Borrower will admit
and certify in writing the exact principal balance of the Obligations that such
Borrower then asserts to be outstanding. Any billing statement or accounting
rendered by

 

24

 

the Lender shall be
conclusive and fully binding on the Borrowers unless the Borrowers give the
Lender specific written notice of exception within 30 days after receipt.

 

Section 2.18           Issuance of Letters of Credit.

 

(a)           Upon any Borrower’s Request the Lender
shall issue, from time to time until the Termination Date, one or more
documentary or standby letters of credit (each, a “Letter of Credit”) for such
Borrower’s account, provided that:

 

(i)            The Lender shall have no obligation to
issue any Letter of Credit for the benefit of a Borrower if (A) a Default
Period exists, or (B) the face amount of the Letter of Credit to be issued
would exceed the lesser of:

 

(1)           $1,000,000 less the Aggregate L/C Amount,
or

 

(2)           such Borrower’s Availability.

 

Each Letter of Credit, if any, shall be issued
pursuant to a separate L/C Application entered by the applicable Borrower and
the Lender, completed in a manner satisfactory to the Lender. The terms and
conditions set forth in each such L/C Application shall supplement the terms and
conditions hereof, but if the terms of any such L/C Application and the terms
of this Agreement are inconsistent, the terms hereof shall control.

 

(b)           No Letter of Credit shall be issued with
an expiry date later than the Maturity Date.

 

(c)           Any request for the issuance of a Letter
of Credit under this Section 2.18 shall be deemed to be a representation
by the requesting Borrower that the statements set forth in Section 4.2
hereof are correct as of the time of the request.

 

Section 2.19           Payment of Amounts Drawn Under Letters of
Credit. Each
Borrower agrees to pay to the Lender any and all amounts required to be paid
under the applicable L/C Application, when and as required to be paid thereby,
and the amounts designated below, when and as designated:

 

(a)           Each Borrower hereby agrees to pay the
Lender on the day a draft is honored under any Letter of Credit a sum equal to
all amounts drawn under such Letter of Credit plus any and all reasonable
charges and expenses that the Lender may pay or incur relative to such
draw, plus interest on all such amounts, charges and expenses as set forth
below (all such amounts are hereinafter referred to as the “Obligation of
Reimbursement”).

 

(b)           Each Borrower hereby agrees to pay the
Lender on demand interest on all amounts, charges and expenses payable by such
Borrower to the Lender under this Section 2.19, accrued from the date any
such draft, charge or expense is paid by the Lender until payment in full by
such Borrower at the Revolving Floating Rate.

 

25

 

If a Borrower fails to pay to the Lender promptly the
amount of its Obligation of Reimbursement in accordance with the terms hereof
and the L/C Application pursuant to which such Letter of Credit was issued, the
Lender is hereby irrevocably authorized and directed, in its sole discretion,
to make a Revolving Advance in an amount sufficient to discharge the Obligation
of Reimbursement, including all interest accrued thereon but unpaid at the time
of such Revolving Advance, and such Revolving Advance shall be evidenced by the
Revolving Note and shall bear interest as provided in Section 2.8 hereof.

 

Section 2.20                                Special Account. If this Credit Facility is terminated
for any reason whatsoever, while any Letter of Credit is outstanding for any
Borrower’s account, such Borrower shall thereupon pay the Lender in immediately
available funds for deposit in the Special Account an amount equal to the
maximum aggregate amount available to be drawn under all Letters of Credit then
outstanding for such Borrower’s account, assuming compliance with all
conditions for drawing thereunder. The Special Account shall be maintained for
the Lender by any financial institution acceptable to the Lender. Any interest
earned on amounts deposited in the Special Account shall be credited to the
Special Account. Amounts on deposit in the Special Account may be applied
by the Lender at any time or from time to time to such Borrower’s Obligation of
Reimbursement or any other Obligations, in the Lender’s sole discretion, and
shall not be subject to withdrawal by any Borrower so long as the Lender
maintains a security interest therein. The Lender agrees to transfer any
balance in the Special Account to such Borrower at such time as the Lender is
required to release its security interest in the Special Account under
applicable law.

 

Section 2.21                                Obligations Absolute. The obligations of each Borrower
arising under Section 2.18 shall be absolute, unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement, under all circumstances whatsoever, including (without limitation)
the following circumstances:

 

(a)                                  any lack of validity or enforceability of
any Letter of Credit or any other agreement or instrument relating to any
Letter of Credit (collectively the “Related Documents”);

 

(b)                                 any amendment or waiver of or any consent
to departure from all or any of the Related Documents;

 

(c)                                  the existence of any claim, setoff,
defense or other right which any Borrower may have at any time, against
any beneficiary or any transferee of any Letter of Credit (or any persons or
entities for whom any such beneficiary or any such transferee may be
acting), or other person or entity, whether in connection with this Agreement,
the transactions contemplated herein or in the Related Documents or any
unrelated transactions;

 

(d)                                 any statement or any other document
presented under any Letter of Credit proving to be forged, fraudulent, invalid
or insufficient in any respect or any statement therein being untrue or
inaccurate in any respect whatsoever;

 

26

 

(e)                                  payment by or on behalf of the Lender
under any Letter of Credit against presentation of a draft or certificate which
does not strictly comply with the terms of such Letter of Credit; or

 

(f)                                    any other circumstance or happening
whatsoever, whether or not similar to any of the foregoing.

 

ARTICLE III

 

Security Interest; Occupancy;
Setoff

 

Section 3.1                                      Grant of Security Interest. Each Borrower hereby pledges, assigns
and grants to the Lender a security interest (collectively referred to as the “Security
Interest”) in the Collateral, as security for the payment and performance of
the Obligations. Upon request by the Lender, each Borrower will grant the
Lender a security interest in all commercial tort claims it may have
against any Person.

 

Section 3.2                                      Notification of Account Debtors and Other
Obligors. The
Lender may during any Default Period notify any account debtor or other
person obligated to pay the amount due that such right to payment has been
assigned or transferred to the Lender for security and shall be paid directly
to the Lender. Each Borrower will join in giving such notice if the Lender so
requests. At any time after any Borrower or the Lender gives such notice to an account
debtor or other obligor, the Lender may, but need not, in the Lender’s name or
in any Borrower’s name, (a) demand, sue for, collect or receive any money
or property at any time payable or receivable on account of, or securing, any
such right to payment, or grant any extension to, make any compromise or
settlement with or otherwise agree to waive, modify, amend or change the
obligations (including collateral obligations) of any such account debtor or
other obligor; and (b) as each Borrower’s agent and attorney-in-fact,
notify the United States Postal Service to change the address for delivery of
such Borrower’s mail to any address designated by the Lender, otherwise
intercept such Borrower’s mail, and receive, open and dispose of such Borrower’s
mail, applying all Collateral as permitted under this Agreement and holding all
other mail for such Borrower’s account or forwarding such mail to such Borrower’s
last known address.

 

Section 3.3                                      Assignment of Insurance. As additional security for the payment
and performance of the Obligations, each Borrower hereby assigns to the Lender
any and all monies (including, without limitation, proceeds of insurance and
refunds of unearned premiums) due or to become due under, and all other rights
of such Borrower with respect to, any and all policies of insurance now or at
any time hereafter covering the Collateral, to the extent such rights may be
assigned in accordance with such policies, or any evidence thereof or any
business records or valuable papers pertaining thereto, and such Borrower
hereby directs the issuer of any such policy to pay all such monies directly to
the Lender. At any time, after and during the continuance of an Event of
Default, the Lender may (but need not), in the Lender’s name or in any
Borrower’s name, execute and deliver proof of claim, receive all such monies,
endorse checks and other instruments representing payment of such monies, and
adjust, litigate, compromise or release any claim against the issuer of any
such policy.

 

27

 

Section 3.4                                      Occupancy

 

(a)                                  Each Borrower hereby irrevocably grants
to the Lender the right to take exclusive possession of the Premises at any
time during a Default Period.

 

(b)                                 The Lender may use the Premises only
to hold, process, manufacture, sell, use, store, liquidate, realize upon or
otherwise dispose of goods that are Collateral and for other purposes that the
Lender may in good faith deem to be related or incidental purposes.

 

(c)                                  The Lender’s right to hold the Premises
shall cease and terminate upon the earlier of (i) payment in full and
discharge of all Obligations and termination of the Commitment, and (ii) final
sale or disposition of all goods constituting Collateral and delivery of all
such goods to purchasers.

 

(d)                                 The Lender shall not be obligated to pay
or account for any rent or other compensation for the possession, occupancy or
use of any of the Premises; provided, however, that if the Lender does pay or
account for any rent or other compensation for the possession, occupancy or use
of any of the Premises, the Borrowers shall reimburse the Lender promptly for
the full amount thereof. In addition, the Borrowers will pay, or reimburse the
Lender for, all taxes, fees, duties, imposts, charges and expenses at any time
incurred by or imposed upon the Lender by reason of the execution, delivery,
existence, recordation, performance or enforcement of this Agreement or the
provisions of this Section 3.4.

 

Section 3.5                                      License. Each Borrower hereby grants to the Lender a
non-exclusive, worldwide and royalty-free license to use or otherwise exploit
all trademarks, franchises, trade names, copyrights and patents of such
Borrower for the purpose of selling, leasing or otherwise disposing of any or
all Collateral during any Default Period. Notwithstanding the foregoing, such
grant shall not constitute an assignment of any Intellectual Property License
to the extent granting such a license is prohibited by or would constitute a
default under any such Intellectual Property License (but only to the extent
such prohibition is enforceable under applicable law).

 

Section 3.6                                      Financing Statement. The Borrowers authorize the Lender to
file from time to time where permitted by law, such financing statements
against collateral described as ‘all personal property’ or describing specific
items of collateral including commercial tort claims as the Lender deems
necessary or useful to perfect the Security Interest. A carbon, photographic or
other reproduction of this Agreement or of any financing statements signed by
the Borrower is sufficient as a financing statement and may be filed as a
financing statement in any state to perfect the security interests granted
hereby. For this purpose, the following information is set forth:

Section 3.7                                      Setoff. Each Borrower agrees that the Lender may at any
time or from time to time during any Default Period, at its sole discretion and
without demand and without notice to anyone, setoff any liability owed to such
Borrower by the Lender, whether or not due, against any Obligation, whether or
not due. In addition, whether or not a Default Period exists, each other Person
holding a participating interest in any Obligations shall have the right to
appropriate or setoff any deposit or other liability then owed by such Person
to such Borrower, whether or not due, and apply the same to the payment of said
participating interest, as fully as if such Person had lent directly to such
Borrower the amount of such participating interest.

 

Section 3.8                                      Security Interest in Special Account. Each Borrower hereby pledges, and
grants to the Lender a security interest in, all funds held in the Special
Account from time to time and all proceeds thereof, as security for the payment
of all Obligations.

Letters of Credit.
The Lender’s obligation to make each Advance or to issue each Letter of Credit

ARTICLE V

 

Representations and Warranties

 

Each Borrower represents and warrants to the Lender as
follows:

 

Section 5.1                                      Corporate Existence and Power; Name;
Chief Executive Office; Inventory and Equipment Locations; Tax Identification
Number. Diamond
is a corporation, duly organized, validly existing and in good standing under
the laws of the State of Iowa, Heska is a corporation, duly organized, validly
existing and in good standing under the laws of the State of Delaware. Each
Borrower is duly licensed or qualified to transact business in all
jurisdictions where the character of the property owned or leased or the nature
of the business transacted by it makes such licensing or qualification
necessary. No dissolution or termination of any Borrower has occurred, and no
notice of dissolution or articles of termination have been filed with respect
to any Borrower. Each Borrower has all requisite corporate power and authority,
to conduct its business, to own its properties and to execute and deliver, and
to perform all of its obligations under the Loan Documents. Since 1994,
each Borrower has done business solely under the names set forth in Schedule 5.1
hereto. Each Borrower’s chief executive office and principal place of business
is located at the address set forth under the name of such Borrower in Schedule 5.1
hereto, and all of such Borrower’s records relating to its business or the
Collateral are kept at that location. All Inventory and Equipment is located at
that location or at one of the other locations set forth in Schedule 5.1
hereto. Each Borrower’s tax identification number is correctly set forth in Section 3.6
hereto.

 

Section 5.2                                      Authorization of Borrowing; No Conflict
as to Law or Agreements. The execution, delivery and performance by each Borrower of the Loan
Documents and the borrowings from time to time hereunder have been duly
authorized by all necessary corporate action and do not and will not (i) require
any consent or approval of such Borrower’s Owners; (ii) require any
authorization, consent or approval by, or registration, declaration or filing
with, or notice to, any governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, or any third party, except such
authorization, consent, approval, registration, declaration, filing or notice
as has been obtained, accomplished or given prior to the date hereof; (iii) violate
any provision of any law, rule or regulation (including, without
limitation, Regulation X of the Board of Governors of the Federal Reserve
System) or of

 

30

 

any order, writ,
injunction or decree presently in effect having applicability to such Borrower
or of such Borrower’s articles of incorporation and bylaws; (iv) result in
a breach of or constitute a default under any indenture or loan or credit
agreement or any other material agreement, lease or instrument to which such
Borrower is a party or by which it or its properties may be bound or
affected; or (v) result in, or require, the creation or imposition of any
mortgage, deed of trust, pledge, lien, security interest or other charge or
encumbrance of any nature (other than the Security Interest) upon or with
respect to any of the properties now owned or hereafter acquired by such
Borrower.

 

Section 5.3                                      Legal Agreements.

 

(a)                                  Immediately prior to execution of this
Agreement, the Former Credit Agreement constituted the legal, valid and binding
obligations of each Borrower, enforceable against each Borrower in accordance
with its terms, subject to general principles of equity and the effects of
bankruptcy and insolvency laws applicable to creditors generally. No Borrower has
any claim, defense or offset to enforcement of the Former Credit Agreement.

 

(b)                                 This Agreement constitutes and, upon due
execution by each Borrower, the other Loan Documents will constitute the legal,
valid and binding obligations of each Borrower, enforceable against such
Borrower in accordance with their respective terms, subject to general
principles of equity and the effects of bankruptcy and insolvency laws
applicable to creditors generally.

 

Section 5.4                                      Subsidiaries. No Borrower has any Subsidiaries except
as set forth in Schedule 5.4.

 

Section 5.5                                      Financial Condition; No Adverse Change. Heska has heretofore furnished to the
Lender its consolidated and consolidating financial statements and those
statements fairly present the Borrowers’ financial condition on the dates
thereof and the results of its operations and cash flows for the periods then
ended and were prepared in accordance with generally accepted accounting
principles (except for the absence of footnotes and subject to normal year-end
adjustments with respect to unaudited financial statements). Since the date of
the most recent financial statements, to the date hereof, there has been no
material adverse change in any Borrower’s business, properties or condition
(financial or otherwise).

 

Section 5.6                                      Litigation. Except as set forth in Schedule 5.6 hereto,
there are no actions, suits or proceedings pending or, to any Borrower’s
knowledge, threatened against or affecting any Borrower or the properties of
any Borrower before any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, which, if determined
adversely to such Borrower, would have a material adverse effect on the
financial condition, properties or operations of such Borrower.

 

Section 5.7                                      Regulation U. No Borrower is engaged in the business
of extending credit for the purpose of purchasing or carrying margin stock
(within the meaning of Regulation U of the Board of Governors of the Federal
Reserve System), and no part of the proceeds of any

 

31

 

Advance will be used to
purchase or carry any margin stock or to extend credit to others for the
purpose of purchasing or carrying any margin stock.

 

Section 5.8                                      Taxes. Each Borrower and its Affiliates have paid or caused
to be paid to the proper authorities when due all federal, state and local
taxes required to be withheld by each of them (other than (a) any such tax
whose amount, applicability or validity is being contested in good faith by appropriate
proceedings and for which proper reserves have been made, or (b) any such
taxes in an aggregate amount among all Borrowers less than $25,000 at any given
time). Each Borrower and its Affiliates have filed all federal, state and local
tax returns which to the knowledge of the officers of such Borrower or any
Affiliate, as the case may be, are required to be filed, and each Borrower
and its Affiliates have paid or caused to be paid to the respective taxing
authorities all taxes as shown on said returns or on any assessment received by
any of them to the extent such taxes have become due (other than (a) any
such tax whose amount, applicability or validity is being contested in good
faith by appropriate proceedings and for which proper reserves have been made,
or (b) any such taxes in an aggregate amount among all Borrowers less than
$25,000 at any given time).

 

Section 5.9                                      Titles and Liens. Each Borrower has good and absolute
title to all Collateral described in the collateral reports provided to the Lender
and all other Collateral, properties and assets (other than assets identified
as being subject to capital leases) reflected in the latest financial
statements referred to in Section 5.5 and all proceeds thereof, free and
clear of all mortgages, security interests, liens, adverse claims and
encumbrances, except for Permitted Liens. No financing statement naming any
Borrower as debtor is on file in any office except to perfect only Permitted
Liens.

 

Section 5.10                                Plans. Except as disclosed to the Lender in writing prior
to the date hereof, no Borrower nor any Affiliates of any Borrower maintains or
has maintained any Plan. To the best of its knowledge, no Borrower nor any
Affiliate of any Borrower has received any notice or has any knowledge to the
effect that it is not in full compliance with any of the requirements of ERISA,
except as set forth on Schedule 5.10. No Reportable Event or other fact or
circumstance which may have an adverse effect on the Plan’s tax qualified

(a)                                  Definitions. As used in this Agreement, the
following terms shall have the following meanings:

 

(i)                                     “Environmental Law” means any federal,
state, local or other governmental statute, regulation, law or ordinance

thereof, and all other chemicals, wastes, substances and materials listed in,
regulated by or identified in any Environmental Law.

as previously disclosed to Lender, there are not present in, on or under the
Premises any Hazardous Substances in such form or quantity as to create
any liability or obligation for any Borrower or for the Lender under common law
of any jurisdiction or under any Environmental Law, and no Hazardous Substances
have ever been stored, buried, spilled, leaked, discharged, emitted or released
in, on or under the Premises in such a way as to create any such liability.

 

(c)                                  Except as set forth in Schedule 5.12,
to each Borrower’s best knowledge, no Borrower has disposed of Hazardous
Substances in such a manner as to create any liability under any Environmental
Law.

 

(d)                                 Except as previously disclosed to Lender,
there are not and there never have been any requests, claims, notices,
investigations, demands, administrative proceedings, hearings or litigation,
relating in any way to the Premises or any Borrower, alleging liability under,
violation of, or noncompliance with any Environmental Law or any license,
permit or other authorization issued pursuant thereto, which could create
liability to any Borrower in excess of $25,000. To each Borrower’s best
knowledge, no such matter is threatened or impending.

 

(e)                                  To each Borrower’s best knowledge, except
as previously disclosed to Lender, each Borrower’s businesses are and have in
the past always been conducted in accordance with all Environmental Laws and
all licenses, permits and other authorizations required pursuant to any
Environmental Law and necessary for the lawful and efficient operation of such
businesses are in the Borrowers’ possession and are in full force and effect.
Except as set forth in Schedule 5.12, to each Borrower’s best knowledge,
there is no threat that any permit required under any Environmental Law will be
withdrawn, terminated, limited or materially changed.

 

(f)                                    To each Borrower’s best knowledge, except

Response, Compensation and Liability Information System or any similar federal,
state or local list, schedule, log, inventory or database.

 

(g)                                 Except as set forth in Schedule 5.12,
each Borrower has delivered to Lender all environmental assessments, audits,
reports, permits, licenses and other

 

33

 

documents
describing or relating in any way to the Premises or such Borrower’s businesses
to the extent in such Borrower’s possession or control.

 

Section 5.13                                Submissions to Lender. All financial and other information
provided to the Lender by or on behalf of each Borrower in connection with such
Borrower’s request for the credit facilities contemplated hereby were true and
correct in all material respects as of the date given and, as to projections,
valuations or proforma financial statements, presented, at the time given, a
good faith opinion as to such projections, valuations and proforma condition
and results. It is recognized by the Lender that projections and forecasts
provided by or on behalf of the Borrowers, although reflecting the Borrowers’
good faith projections or forecasts based on methods and data which the
Borrowers believe to be reasonable and accurate, are not to be viewed as facts
and that actual results during the periods covered by any such projections and
forecasts may (and are likely to) differ from the projected or forecasted
results. Notwithstanding the foregoing, it is recognized by the Borrowers that
the Lender will rely on, among other things, the Borrowers’ projections in
setting financial covenants set forth in Articles VI and VII hereof, and
nothing in this Section 5.13 shall be construed as a waiver of the Lender’s
right to rely on such covenants or to exercise its remedies in case of a breach
of such covenants.

 

Section 5.14                                Financing Statements. Each Borrower has provided to the
Lender signed financing statements sufficient when filed to perfect the
Security Interest and the other security interests created by the Security
Documents. When such financing statements are filed in the offices noted
therein, the Lender will have a valid and perfected security interest in all
Collateral and all other collateral described in the Security Documents which
is capable of being perfected by filing financing statements. None of the
Collateral or other collateral covered by the Security Documents is or will
become a fixture on real estate, unless a sufficient fixture filing is in
effect with respect thereto.

 

Section 5.15                                Rights to Payment. To the best of each Borrower’s
knowledge, except as disclosed to Lender, each right to payment and each
instrument, document, chattel paper and other agreement constituting or
evidencing Collateral or other collateral covered by the Security Documents is
(or, in the case of all future Collateral or such other collateral, will be
when arising or issued) the valid, genuine and legally enforceable obligation,
subject to no defense, setoff or counterclaim, of the account debtor or other
obligor named therein or in such Borrower’s records pertaining thereto as being
obligated to pay such obligation.

 

Section 5.16                                Financial Solvency. Both before and after giving effect to
all of the transactions contemplated in the Loan Documents, no Borrower, and no
Affiliate of any Borrower:

 

(a)                                  was or will be insolvent, as that term is
used and defined in Section 101(32) of the United States Bankruptcy Code
and Section 2 of the Uniform Fraudulent Transfer Act;

 

(b)                                 has unreasonably small capital or is
engaged or about to engage in a business or a transaction for which any
remaining assets of such Borrower or such Affiliate are unreasonably small;

 

34

 

(c)                                  by executing, delivering or performing
its obligations under the Loan Documents or other documents to which it is a
party or by taking any action with respect thereto, intends to, nor believes
that it will, incur debts beyond its ability to pay them as they mature;

 

(d)                                 by executing, delivering or performing
its obligations under the Loan Documents or other documents to which it is a party
or by taking any action with respect thereto, intends to hinder, delay or
defraud either its present or future creditors; and

 

(e)                                  at this time contemplates filing a
petition in bankruptcy or for an arrangement or reorganization or similar
proceeding under any law of any jurisdiction, or, to the best knowledge of any
Borrower, is the subject of any actual, pending or threatened bankruptcy,
insolvency or similar proceedings under any law of any jurisdiction.

(a)                                  Each Borrower will (i) comply with
the requirements of applicable laws and regulations, the non-compliance with
which would materially and adversely affect its business or its financial
condition and (ii) use and keep the Collateral, and require that others
use and keep the Collateral, only for lawful purposes, without violation of any
federal, state or local law, statute or ordinance.

 

(b)                                 Without limiting the foregoing
undertakings, each Borrower specifically agrees that it will comply in all
material respects with all applicable Environmental Laws and obtain and comply
with all permits, licenses and similar approvals required by any Environmental
Laws, and will not generate, use, transport, treat, store or dispose of any
Hazardous Substances in such a manner as to create any material liability or
obligation under the common law of any jurisdiction or any Environmental Law.

 

Section 6.5                                      Payment of Taxes and Other Claims;
Payment of Past-Due Accounts. Each Borrower will pay or discharge, when due, (a) all
taxes, assessments and governmental charges levied or imposed upon it or upon

limitation, the Collateral) or upon or against the creation, perfection or
continuance of the Security Interest, prior to the date on which penalties
attach thereto, (b) all federal, state and local taxes required to be
withheld by it, and (c) all lawful claims for labor, materials and

properties of such Borrower; provided, that no Borrower shall be required to
pay any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings and for
which proper reserves have been made. No Borrower shall have any Past Due

Section 6.6                                      Maintenance of Properties.

 

(a)                                  Each Borrower will keep and maintain the
Collateral, the other collateral covered by the Security Documents and all of
its other properties necessary or useful in its business in good condition,
repair and working order (normal wear and tear excepted) and will from time to
time replace or repair any worn, defective or broken parts; provided, however,
that nothing in this Section 6.6 shall prevent any Borrower from
discontinuing the operation and maintenance of any of its properties if such

 

38

 

discontinuance is,
in such Borrower’s judgment, desirable in the conduct of such Borrower’s
business and not disadvantageous in any material respect to the Lender.

 

(b)                                 Each Borrower will defend the Collateral
against all claims or demands of all persons (other than the Lender) claiming
the Collateral or any interest therein.

 

(c)                                  Each Borrower will keep all Collateral

Section 6.7                                      Insurance. Each Borrower will obtain and at all times maintain
insurance with insurers believed by such Borrower to be responsible and
reputable, in such amounts and against such risks as may from time to time
be reasonably required by the Lender, but in all events in such amounts and
against such risks as is usually carried by companies engaged in similar
business and owning similar properties in the same general areas in which such
Borrower operates. Without limiting the generality of the foregoing, each
Borrower will at all times keep all tangible Collateral insured against risks
of fire (including so-called extended coverage), theft, collision (for
Collateral consisting of motor vehicles) and such other risks and in such
amounts as the Lender may reasonably request, with any loss payable to the
Lender to the extent of its interest, and all policies of such insurance shall
contain a lender’s loss payable endorsement for the Lender’s benefit acceptable
to the Lender. All policies of liability insurance required hereunder shall
name the Lender as an additional insured.

documents and chattel papers constituting Collateral, duly endorsed or assigned
by such Borrower.

 

Section 6.10                                Collateral Accounts.

 

(a)                                  If, notwithstanding the instructions to
debtors to make payments to the Lockbox, any Borrower receives any payments on
Receivables, such Borrower shall deposit such payments into such Borrower’s
Collateral Account. Until so deposited, such Borrower shall hold all such
payments in trust for and as the property of the Lender and shall not commingle
such payments with any of its other funds or property; provided, however, that
the foregoing shall not be construed to allow the Lender to withhold any such
payments after full payment and discharge of all Obligations.

 

(b)                                 Amounts deposited in any Collateral
Account shall not bear interest and shall not be subject to withdrawal by any
Borrower, except after full payment and discharge of all Obligations; provided,
however, that if the Borrowers’ only outstanding Obligations are principal owing
under the Equipment Note and the Term Loan B Note, and if no such principal
amount is due, the Lender agrees to remit such amounts to such Borrower’s
demand deposit account maintained with Wells Fargo Bank.

 

39

 

(c)                                  All deposits in any Collateral Account
shall constitute proceeds of Collateral and shall not constitute payment of the
Obligations. The Lender shall from time to time within one Banking Day, apply
deposited funds in each Collateral Account to the payment of the Obligations,
in any order or manner of application satisfactory to the Lender, by
transferring such funds to the Lender’s general account.

 

(d)                                 All items deposited in any Collateral
Account shall be subject to final payment. If any such item is returned
uncollected, the applicable Borrower will immediately pay the Lender, or, for
items deposited in a Collateral Account, the bank maintaining such account, the
amount of that item, or such bank at its discretion may charge any
uncollected item to any commercial account or other account belonging to the
Borrower to whom the item was payable.

 

Section 6.11                                Performance by the Lender. If any Borrower at any time fails to
perform or observe any of the foregoing covenants contained in this Article VI
or elsewhere herein, and if such failure shall continue for a period of ten
calendar days after the Lender gives such Borrower written notice thereof (or
in the case of the agreements contained in Sections 6.5, 6.7 and 6.10,
immediately upon the occurrence of such failure, without notice or lapse of
time), the Lender may, but need not, perform or observe such covenant on
behalf and in the name, place and stead of such Borrower (or, at the Lender’s
option, in the Lender’s name) and may, but need not, take any and all other
actions which the Lender may reasonably deem necessary to cure or correct
such failure (including, without limitation, the payment of taxes, the
satisfaction of security interests, liens or encumbrances, the performance of
obligations owed to account debtors or other obligors, the procurement and
maintenance of insurance, the execution of assignments, security agreements and
financing statements, and the endorsement of instruments); and such Borrower
shall thereupon pay to the Lender on demand the amount of all monies expended
and all costs and expenses (including reasonable attorneys’ fees and legal
expenses) incurred by the Lender in connection with or as a result of the
performance or observance of such agreements or the taking of such action by
the Lender, together with interest thereon from the date expended or incurred
at the Revolving Floating Rate. To facilitate the Lender’s performance or
observance of such covenants of the Borrowers, each Borrower hereby irrevocably
appoints the Lender, or the Lender’s delegate, acting alone, as such Borrower’s
attorney in fact (which appointment is coupled with an interest) with the right
(but not the duty) from time to time to create, prepare, complete, execute,
deliver, endorse or file in the name and on behalf of such Borrower any and all
instruments, documents, assignments, security agreements, financing statements,
applications for insurance and other agreements and writings required to be
obtained, executed, delivered or endorsed by such Borrower under this Section 6.11.

 

Section 6.12                                Minimum Capital. Heska will maintain, on a consolidated
basis, as of each date listed below, its Capital at an amount not less than the

Borrower’s business;

 

(i)                                     any preexisting Lien (whether or not

(b)                                 Such Borrower will not create or permit
to exist any Subsidiary; provided, however, that so long as no Default Period

Lender to create a first priority security interest on behalf of the Lender, or
to perfect such security interest, in all assets of such subsidiary, or (ii) any
foreign subsidiary.

 

Section 7.5                                      Dividends. Such Borrower will not declare or pay any dividends
(other than dividends payable solely in stock of such Borrower) on any class of
its stock or make any payment on account of the purchase, redemption or other
retirement of any shares of such stock or make any distribution in respect
thereof, either directly or indirectly; provided, however, that so long as no
Default Period then exists or would occur immediately following or as a result
of such action, (A) any Borrower that is a Subsidiary of Heska may pay
dividends to Heska so long as such Subsidiary’s Tangible Net Worth both before
and after such dividend equals or exceeds $100,000; and (B) Heska may repurchase
capital stock of Heska held by any employee provided Heska is required to do so
pursuant to any employee equity subscription agreement, stock ownership plan or
stock option agreement in effect from time to time; and provided further that
the aggregate price paid for all such repurchased, redeemed, acquired or
retired capital shall not exceed $100,000 during any fiscal year.
Notwithstanding the foregoing, the exercise of stock options for the purchase
of Heska’s capital stock shall not, by means of any deemed repurchase of shares
as a result of a cashless exercise or otherwise, cause a breach of this Section 7.5.

stock of any Subsidiary, (ii) all or a substantial part of its
assets, or (iii) any Collateral or any interest therein (whether in one
transaction or in a series of transactions) to any other Person other than
(A) sale of Inventory in the ordinary course of business; (B) licenses
and sublicenses to third parties of patents, patent applications, trademarks
and copyrights, in each case in the ordinary course of its business as

receivables to a collection agency in the ordinary course of business; and (F) other

reasonably be expected to have a material adverse effect. Such Borrower will
not in any manner transfer any property without prior or present receipt of
full and adequate consideration.

 

Section 7.7                                      Consolidation and Merger; Asset
Acquisitions.
Such Borrower will not consolidate with or merge into any Person, or permit any
other Person to merge into it, or acquire (in a transaction analogous in

unreasonably withhold its consent to any merger or acquisition.

 

47

 

Section 7.8                                      Restrictions on Nature of Business. Such Borrower will not engage in any

accounting principles other than as required by GAAP, the SEC, or NASDAQ. Such
Borrower will not adopt, permit or consent to any change in its fiscal year.

50

 

determine are

which each Borrower hereby expressly waives;

 

51

 

(c)                                  the Lender may refuse to fund any
requested Advance made by any Borrower;

Borrower and without further action, apply any and all money owing by the
Lender to any Borrower to the payment of the Obligations;

 

(e)                                  the Lender may exercise and enforce
any and all rights and remedies available upon default to a secured party under
the UCC, including, without limitation, the right to take possession of
Collateral, or any evidence thereof, proceeding without judicial process or by
judicial process (without a prior hearing or notice thereof, which each
Borrower hereby expressly waives) and the right to sell, lease or otherwise
dispose of any or all of the Collateral, and, in connection therewith, each
Borrower will on demand assemble the Collateral and make it available to the
Lender at a place to be designated by the Lender which is reasonably convenient
to both parties;

 

(f)                                    the Lender may exercise and enforce

purpose of amending and restating the Former Credit Agreement.

 

Section 9.2                                      Release. Each Borrower hereby absolutely and unconditionally
releases and forever discharges the Lender, the Participants and any and all
parent corporations, subsidiary corporations, affiliated corporations,
insurers, indemnitors, successors and assigns thereof, together with all of the
present and former directors, officers, agents and employees of any of the foregoing,
from any and all claims, demands or causes of action of any kind, nature or
description relating to the transactions contemplated by this Agreement,
whether arising in law or equity or upon contract or tort or under any state or
federal law or otherwise, which such Borrower has had or has made claim to have
against any such person for or by reason of any act, omission, matter, cause or
thing whatsoever arising from the beginning of time to and including the date
of this Agreement, whether such claims, demands and causes of action are
matured or

 

52

 

unmatured or known or
unknown. For greater certainty, nothing herein shall constitute a release by
any Borrower of any Person for any such claim, demand or cause of action
arising after the date of this Agreement.

 

Section 9.3                                      No Waiver; Cumulative Remedies. No failure or delay by the Lender in
exercising any right, power or remedy under the Loan Documents shall operate as
a waiver thereof; nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy under the Loan Documents. The remedies
provided in the Loan Documents are cumulative and not exclusive of any remedies
provided by law.

 

Section 9.4                                      Amendments, Etc. No amendment, modification, termination
or waiver of any provision of any Loan Document or consent to any departure by
any Borrower therefrom or any release of a Security Interest shall be effective
unless the same shall be in writing and signed by the Lender, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No notice to or demand on any Borrower in any
case shall entitle such Borrower to any other or further notice or demand in
similar or other circumstances.

 

Section 9.5                                      Addresses for Notices, Etc. Except as otherwise expressly provided

execute and deliver or endorse any and all instruments, documents, conveyances,
assignments, security agreements, financing statements and other agreements and
writings that the Lender may reasonably request in order to secure,
protect, perfect or enforce the Security Interest or the Lender’s rights under
the Loan Documents (but any failure to request or assure that any Borrower
executes, delivers or endorses any such item shall not affect or impair the
validity, sufficiency or enforceability of the Loan Documents and the Security
Interest, regardless of whether any such item was or was not executed,
delivered or endorsed in a similar context or on a prior occasion). All
requests under Section 9-210 of the UCC (i) shall be made in a

the Lender respond to all such requests which on their face appear to come from
an authorized individual and releases the Lender from any liability for so
responding. The Borrowers shall pay Lender the maximum amount allowed by law
for responding to such requests.

 

Section 9.7                                      Collateral. This Agreement does not contemplate a sale of
accounts, contract rights or chattel paper, and, as provided by law, each
Borrower is entitled to any surplus and shall remain liable for any deficiency.
The Lender’s duty of care with respect to Collateral in its possession (as
imposed by law) shall be deemed fulfilled if it exercises reasonable care in
physically keeping such Collateral, or in the case of Collateral in the custody
or possession of a bailee or other third person, exercises reasonable care in
the selection of the bailee or other third person, and the Lender need not
otherwise preserve, protect, insure or care for any Collateral. The Lender
shall not be obligated to preserve any rights any Borrower may have
against prior parties, to realize on the Collateral at all or in any particular
manner or order or to apply any cash proceeds of the Collateral in any
particular order of application.

 

Section 9.8                                      Costs and Expenses. Each Borrower, jointly and severally,
agrees to pay on demand all costs and expenses, including (without limitation)
reasonable attorneys’ fees, incurred by the
Lender in connection with the Obligations, this Agreement, the Loan Documents,
and any other document or agreement related hereto or thereto, and the
transactions contemplated hereby, including without limitation all such costs,
expenses and fees incurred in connection with the negotiation, preparation,
execution, amendment, administration, performance, collection and enforcement
of the Obligations and all such documents and

 

54

 

agreements and the
creation, perfection, protection, satisfaction, foreclosure or enforcement of
the Security Interest.

 

Section 9.9                                      Indemnity. In addition to the payment of expenses pursuant to Section 9.8,
each Borrower, jointly and severally, agrees to indemnify, defend and hold
harmless the Lender, and any of its participants, parent corporations,
subsidiary corporations, affiliated corporations, successor corporations, and
all present and future officers, directors, employees, attorneys and agents of
the foregoing (the “Indemnitees”) from and against any of the following
(collectively, “Indemnified Liabilities”):

 

(i)                                     any and all transfer taxes, documentary
taxes, assessments or charges made by any governmental authority by reason of
the execution and delivery of the Loan Documents or the making of the Advances;

 

(ii)                                  any claims, loss or damage to which any
Indemnitee may be subjected if any representation or warranty contained in
Section 5.12 proves to be incorrect in any respect or as a result of any
violation of the covenant contained in Section 6.4(b); and

 

(iii)                               any and all other liabilities, losses,
damages, penalties, judgments, suits, claims, costs and expenses of any kind or
nature whatsoever (including, without limitation, the reasonable fees and
disbursements of counsel) in connection with the foregoing and any other
investigative, administrative or judicial proceedings, whether or not such
Indemnitee shall be designated a party thereto, which may be imposed on,
incurred by or asserted against any such Indemnitee, in any manner related to
or arising out of or in connection with the making of the Advances and the Loan
Documents or the use or intended use of the proceeds of the Advances;

 

provided that no Borrower shall have any such obligation for any Indemnified
Liabilities arising from any act or omission by an Indemnitee which constitutes
gross negligence or willful misconduct. If any investigative, judicial or
administrative proceeding arising from any of the foregoing is brought against
any Indemnitee, upon such Indemnitee’s request, each Borrower, or counsel
designated by any such Borrower and satisfactory to the Indemnitee, will resist
and defend such action, suit or proceeding to the extent and in the manner
directed by the Indemnitee, at such Borrower’s sole costs and expense. Each
Indemnitee will use its best efforts to cooperate in the defense of any such
action, suit or proceeding. If the foregoing undertaking to indemnify, defend
and hold harmless may be held to be unenforceable because it violates any
law or public policy, each Borrower shall nevertheless make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. Each Borrower’s
obligation under this Section 9.9 shall survive the termination of this
Agreement and the discharge of such Borrower’s other obligations hereunder.

 

Section 9.10                                Participants. The Lender and its participants, if
any, are not partners or joint venturers, and the Lender shall not have any
liability or responsibility for any obligation, act or omission of any of its
participants. All rights and powers specifically conferred upon the Lender may be
transferred or delegated to any of the Lender’s participants, successors or
assigns.

 

55

 

Section 9.11                                Execution in Counterparts. This Agreement and other Loan Documents
may be executed in any number of counterparts, each of which when so
executed and delivered shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same instrument.

 

Section 9.12                                Binding Effect; Assignment; Complete
Agreement; Exchanging Information. The Loan Documents shall be binding upon and inure
to the benefit of the Borrowers and the Lender and their respective successors
and assigns, except that no Borrower shall have the right to assign its rights
thereunder or any interest therein without the Lender’s prior written consent.
This Agreement, together with the Loan Documents, comprises the complete and
integrated agreement of the parties on the subject matter hereof and supersedes
all prior agreements, written or oral, on the subject matter hereof. Without
limiting the Lender’s right to share information regarding any Borrower and its
Affiliates with the Lender’s participants (except that the Lender shall not
share any information with a participant that is a competitor, or an affiliate
of a competitor, of any such Borrower, in the area of researching, developing
and manufacturing animal health products), accountants, lawyers and other
advisors, the Lender, WFC Holdings Corporation, and all direct and indirect
subsidiaries of WFC Holdings Corporation, may exchange any and all
information they may have in their possession regarding any Borrower and
its Affiliates, and each Borrower waives any right of confidentiality it may have
with respect to such exchange of such information. To the extent permitted by
law, each Borrower waives and will not assert against any assignee any claims,
defenses or set-offs which such Borrower could assert against the Lender.

 

Section 9.13                                Severability of Provisions. Any provision of this Agreement which
is prohibited or unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
hereof.

 

Section 9.14                                Headings. Article and Section headings in this
Agreement are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose.

 

Section 9.15                                Governing Law; Jurisdiction, Venue; Waiver of Jury
Trial. The Loan
Documents shall be governed by and construed in accordance with the substantive
laws (other than conflict laws) of the State of Colorado. The parties hereto
hereby (i) consent to the personal jurisdiction of the state and federal
courts located in the State of Colorado in connection with any controversy
related to this Agreement; (ii) waive any argument that venue in any such
forum is not convenient, (iii) agree that any litigation initiated by the
Lender or any Borrower in connection with this Agreement or the other Loan
Documents shall be venued in either the District Court for the City and County
of Denver, Colorado, or the United States District Court, District of Colorado;
and (iv) agree that a final judgment in any such suit, action or
proceeding shall be conclusive and may be enforced in other jurisdictions
by suit on the judgment or in any other manner provided by law. THE PARTIES WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING BASED ON OR PERTAINING TO THIS AGREEMENT.

 

Section 9.16                                Retention of Borrowers’ Records. The Lender shall have no obligation to
maintain any electronic records or any documents, schedules, invoices, agings,
or other papers

 

56

 

delivered to the Lender
by the Borrowers or in connection with the Loan Documents for more than four
months after receipt by the Lender.

 

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized as of the date
first above written.

Litigation
Matters

 

On September 9,
2005, United Vaccines, Inc. (“United”), a customer of Diamond, filed a lawsuit
in Wisconsin against Diamond and Heska alleging various claims, including
breach of contract and breach of warranty, and demanding compensatory and
punitive damages. On October 20, 2005, Diamond and Heska filed a motion to
dismiss certain claims against Diamond and all claims against Heska, as well as
an answer to United’s claims, affirmative defenses and counterclaims on behalf
of Diamond. While Diamond and Heska intend to pursue the matter vigorously and
believe they are entitled to damages from United and that United is not
entitled to damages from Heska or Diamond, there can be no assurance the
ultimate resolution of this case will reflect Heska’s and Diamond’s current
beliefs.

 

 

Schedule 5.10 to Third Amended and

Plans

 

Borrower now maintains or has maintained the following employee pension
benefit plans as defined in ERISA, . 3(2), 29 U.S.C. 1002(2):

 

1.                                       The
Diamond Animal Health, Inc. Pension Plan for Collective Bargaining Unit
Employees.

 

This Defined Benefit Pension Plan is currently frozen. No new
participants may enter the plan nor are any contribution liabilities
accruing. The plan has a funding liability of $235,974 for Termination
purposes, calculated as of May 1, 1998; this liability is a result of the
difference between the GATT rates used to calculate contributions and the PBGC
rates required to be used by a terminating plan. Upon termination, participants
must receive the larger of the accrued benefit calculated using GATT rates and
using PBGC rates. Since the PBGC rates have been consistently lower than the
GATT rates, the Pension Plan has a funding liability on termination. The Plan
can remain frozen until such time as the PBGC rates match the GATT rates or
Diamond chooses to contribute funds to make up the termination funding
liability. The termination funding liability varies from year to year based
upon fluctuations in interest and mortality rates.

 

The Plan does not have a funding liability under the provisions of
Internal Revenue Code . 412, and there are no reportable events.

 

2.                                       The
Diamond Animal Health, Inc. Saving Plan (the “Savings Plan”).

 

The Savings Plan is a profit sharing/401(k) plan. It was merged into
the Heska Corporation 401(k) Plan (the “Heska Plan”) effective January 1,
1998. Diamond Animal Health, Inc. is the wholly owned subsidiary of its
parent, Heska Corporation. Diamond Animal Health, Inc. was acquired by
Heska Corporation in April, 1996. At the time of the acquisition, both Heska
and Diamond sponsored 401(k) plans. In accordance with the provisions of Treas.
Reg. . 1.401(k)-1(d)(3), Heska Corporation determined that it would be in the
best interests of both Heska and Diamond to merge the Savings Plan into the
Heska Plan. Both plans have been submitted to the Internal Revenue Service for
a Determination that:

 

(1)  the Savings Plan was a tax-qualified plan as of the effective
date of the merger; and

 

(2)  the Heska Plan remains a tax-qualified plan on and after the
merger date.

 

3.                                       The
Heska Corporation 401(k) Plan (the “Heska Plan”)

 

The Heska Plan is a defined contribution plan that was established
under the provisions of Section 401(a) of the Internal Revenue Code (“IRC”),
which includes a qualified deferred arrangement as defined in Section 401(k)
of the IRC, for the benefit of eligible employees of

 

 

Heska Corporation. The Heska Plan is subject to the provisions of ERISA.
Benefits under the plan are not guaranteed by the Pension Benefit Guaranty
Corporation. On July 1, 2003, the Heska Plan changed custodians and record
keepers from Principal Life Insurance Company to Putnam Fiduciary Trust
Company.
