                           have requested, and Laurus is hereby authorized at
                           its discretion to make and charge to the Company's

                  (i)      Except as modified by Section 7(a)(iii) below, the
                           Company shall pay interest at the Contract Rate on
                           the unpaid principal balance of each Loan until such

                           of actual days elapsed in a year of 360 days. At

                           continuing, the Contract Rate shall automatically be
                           increased as set forth in the Notes (such increased
                           rate, the "Default Rate"), and all outstanding
                           Obligations, including unpaid interest, shall
                           continue to accrue interest from the date of such
                           Event of Default at the Default Rate applicable to
                           such Obligations.

                           to time (the "Maximum Legal Rate"), and if any
                           provision of this Agreement or any Ancillary
                           Agreement is in contravention of any such law or
                           regulation, interest payable under this Agreement and

                           basis of the Maximum Legal Rate (so that such
                           interest will not exceed the Maximum Legal Rate).

                  (v)      The Company shall pay principal, interest and all
                           other amounts payable hereunder, or under any

                           whatsoever, including any deduction for any set-off

         (j)      all Eligible Accounts (i) represent complete bona fide

         (c)      As Laurus receives the proceeds of Accounts of the Company and
                  the Eligible Subsidiaries, it shall (i) apply such proceeds,
                  as required, to amounts outstanding under the Secured

                  (net of interest, fees and other amounts then due and owing to

                  Company) upon request (but no more often than twice a week).
                  Notwithstanding the foregoing, following the occurrence and
                  during the continuance of an Event of Default, Laurus, may
                  apply such proceeds to the Obligations in such order as Laurus

                  liability company, as the case may be, duly organized, validly
                  existing and in good standing under the laws of its
                  jurisdiction of organization. It and each of its Subsidiaries
                  has the corporate, limited liability company or partnership,

                                      -15-

                  as the case may be, power and authority to own and operate its
                  properties and assets and, insofar as it is or shall be a
                  party thereto, to (i) execute and deliver this Agreement and
                  the Ancillary Agreements, (ii) to issue the Notes (with

                  and is authorized to do business and is in good standing as a
                  foreign corporation, partnership or limited liability company,
                  as the case may be, in all jurisdictions in which the nature
                  or location of its activities and of its properties (both
                  owned and leased) makes such qualification necessary, except
                  for those jurisdictions in which failure to do so has not had,
                  or could not reasonably be expected to have, individually or
                  in the aggregate, a Material Adverse Effect.

         (b)      Subsidiaries. Each of its direct and indirect Subsidiaries,

                           capital of Essential, as of the date hereof, consists
                           of 100,000,000 common voting shares, of which
                           1,000,000 are issued and outstanding.

                  (iv)     The rights, preferences, privileges and restrictions
                           of its shares are as stated in its Articles of
                           Incorporation (the "Articles"). The Warrant Shares
                           have been duly and validly reserved for issuance.
                           When issued in compliance with the provisions of this
                           Agreement and the Company's Articles, the Securities

                  Acquisition and the Second Acquisition (together, herein
                  referred to as the "Acquisitions"), and therefore waives, on a
                  one-time basis, the application of the foregoing provisions of
                  this Section 16(h) but only to the limited extent that
                  completion of the Acquisitions may constitute a breach
                  thereof. For greater certainty, the Company hereby
                  acknowledges and agrees that Laurus shall not be deemed to
                  have approved either the First Acquisition or the Second
                  Acquisition by virtue of this limited waiver.

                  other properties owned, leased or used by it are in good
                  operating condition and repair and are reasonably fit and
                  usable for the purposes for which they are being used. Except
                  as set forth on Schedule 16(i), it is in compliance with all
                  material terms of each lease to which it is a party or is

                           Intellectual Property of any other Person other than
                           such licenses or agreements arising from the purchase

                           their employment by it, except for inventions, trade
                           secrets or proprietary information that have been

         (l)      Litigation. Except as set forth on Schedule 16(l), there is no
                  action, suit, proceeding or investigation pending or, to its
                  knowledge, currently threatened against it that prevents it
                  from entering into this Agreement or the Ancillary Agreements,
                  or from consummating the transactions contemplated hereby or
                  thereby, or which has had, or could reasonably be expected to
                  have, either individually or in the aggregate, a Material
                  Adverse Effect, or could result in any change in its current
                  equity ownership, nor is it aware that there is any basis to
                  assert any of the foregoing. It is not a party to or subject
                  to the provisions of any order, writ, injunction, judgment or

                  by, or to contract with, it because of the nature of the
                  business to be conducted by it; and to its knowledge the
                  continued employment by it of its present employees, and the

                  agreement with it, none of its employees has been granted the
                  right to continued employment by it or to any material
                  compensation following termination of employment with it.

                  have a present intention to terminate the employment of any
                  officer, key employee or group of employees.

                  It has all material franchises, permits, licenses and any
                  similar authority necessary for the conduct of its business as
                  now being conducted by it, the lack of which could, either
                  individually or in the aggregate, reasonably be expected to
                  have a Material Adverse Effect.

         (p)      Environmental and Safety Laws. It is not in violation of any
                  applicable statute, law or regulation relating to the
                  environment or occupational health and safety, and to its
                  knowledge, no material expenditures are or will be required in
                  order to comply with any such existing statute, law or
                  regulation. Except as set forth on Schedule 16(q), no
                  Hazardous Materials (as defined below) are used or have been
                  used, stored, or disposed of by it or, to its knowledge, by
                  any other Person on any property owned, leased or used by it.
                  For the purposes of the preceding sentence, "Hazardous
                  Materials" shall mean:

                  (i)      materials which are listed or otherwise defined as
                           "hazardous" or "toxic" under any applicable local,
                           provincial, state, federal and/or foreign laws and
                           regulations that govern the existence and/or remedy
                           of contamination on property, the protection of the
                           environment from contamination, the control of
                           hazardous wastes, or other activities involving
                           hazardous substances, including building materials;
                           and

                  (ii)     any petroleum products (other than in the ordinary
                           course of business) or nuclear materials.

         (q)      Full Disclosure. It has provided Laurus with all information
                  requested by Laurus in connection with Laurus' decision to
                  enter into this Agreement. Neither this Agreement, the
                  Ancillary Agreements nor the exhibits and schedules hereto and
                  thereto nor any other document delivered by it to Laurus or
                  its attorneys or agents in connection herewith or therewith or
                  with the transactions contemplated hereby or thereby, contain
                  any untrue statement of a material fact nor omit to state a
                  material fact necessary in order to make the statements
                  contained herein or therein, in light of the circumstances in
                  which they are made, not misleading. Any financial projections
                  and other estimates provided to Laurus by it were based on its
                  experience in the industry and on assumptions of fact and
                  opinion as to future events which it, at the date of the
                  issuance of such projections or estimates, believed to be
                  reasonable.

         (r)      Insurance. It has general commercial, product liability, fire
                  and casualty insurance policies with coverages which it
                  believes are customary for companies similarly situated to it
                  in the same or similar business.

         (s)      Patriot Act. It certifies that, to the best of its knowledge,
                  it has not been designated, nor is or shall be owned or
                  controlled, by a "suspected terrorist" as defined in Executive
                  Order 13224. It hereby acknowledges that Laurus seeks to

                                      -22-
<PAGE>

                  comply with all applicable laws concerning money laundering
                  and related activities. In furtherance of those efforts, it
                  hereby represents, warrants and covenants that: (i) none of
                  the cash or property that it will pay or will contribute to
                  Laurus has been or shall be derived from, or related to, any
                  activity that is deemed criminal under United States law; and
                  (ii) no contribution or payment by it to Laurus, to the extent
                  that they are within its control shall cause Laurus to be in
                  violation of the United States Bank Secrecy Act, the United
                  States International Money Laundering Control Act of 1986 or
                  the United States International Money Laundering Abatement and
                  Anti-Terrorist Financing Act of 2001, or the Canadian Proceeds
                  of Crime (Money Laundering) and Terrorist Financing Act. It
                  shall promptly notify Laurus if any of these representations,
                  warranties and covenants ceases to be true and accurate
                  regarding it. It shall provide Laurus with any additional
                  information regarding it thereof that Laurus deems necessary
                  or convenient to ensure compliance with all applicable laws
                  concerning money laundering and similar activities. It
                  understands and agrees that if at any time it is discovered
                  that any of the foregoing representations, warranties and
                  covenants are incorrect, or if otherwise required by
                  applicable law or regulation related to money laundering or
                  similar activities, Laurus may undertake appropriate actions
                  to ensure compliance with applicable law or regulation,
                  including but not limited to segregation and/or redemption of
                  Laurus' investment in it. It further understands that Laurus
                  may release confidential information about it and, if
                  applicable, any underlying beneficial owners, to proper
                  authorities if Laurus, in its sole discretion, determines that
                  it is in the best interests of Laurus in light of relevant
                  rules and regulations under the laws set forth in subsection
                  (ii) above.

         (t)      Company Name; Locations of Offices, Records and Collateral.
                  Schedule 16(t) sets forth its complete name as it appears in
                  official filings in the state or province of its organization,
                  as the case may be, the type of entity it is, the
                  organizational identification number issued by its state or
                  province of organization, as the case may be, or a statement
                  that no such number has been issued, its state or province of
                  organization, and the location of its chief executive office,

                  and locations where records with respect to Collateral are
                  kept (including in each case the county of such locations)
                  and, except as set forth in such Schedule 16(t), such
                  locations have not changed during the preceding twelve months.
                  As of the Closing Date, during the prior five years, except as
                  set forth in Schedule 16(t), it has not been known as or

                  as set forth on Schedule 16(u), each SEC Report was, at the
                  time of its filing, in substantial compliance with the
                  requirements of its respective form and none of the SEC
                  Reports , nor the financial statements (and the notes thereto)

                  GAAP applied on a consistent basis during the periods involved
                  (except (i) as may be otherwise indicated in such financial
                  statements or the notes thereto or (ii) in the case of
                  unaudited interim statements, to the extent they may not

                  Securities become freely tradeable or an exemption from the
                  prospectus registration or equivalent requirements of
                  applicable securities laws in respect of such sale or delivery
                  is available, except as required by applicable securities
                  laws.

         (f)      Dilution. Subject to any maximum conversion or restrictions
                  contained in this Agreement or in any Ancillary Agreement

                  issue the shares of Common Stock upon exercise of the Warrant
                  is binding upon the Company and enforceable regardless of the

                  Geotech AB, a wholly-owned subsidiary of Geotech BC)(the
                  "Second Acquisition"); and (iii) for general working capital
                  purposes.

         (b)      Taxes. It shall promptly pay and discharge, or cause to be
                  paid and discharged, when due and payable, all lawful taxes,
                  assessments and governmental charges or levies imposed upon it
                  income, profits, property or business, as the case may be;
                  provided, however, that any such tax, assessment, charge or
                  levy need not be paid currently if (i) the validity thereof
                  shall currently and diligently be contested in good faith by
                  appropriate proceedings, (ii) such tax, assessment, charge or
                  levy shall have no effect on the Lien priority of Laurus in
                  the Collateral, and (iii) if it shall have set aside on its
                  books adequate reserves with respect thereto in accordance
                  with GAAP; and provided, further, that it shall pay all such
                  taxes, assessments, charges or levies forthwith upon the
                  commencement of proceedings to foreclose any lien which may
                  have attached as security therefor.

         (c)      Insurance. It shall bear the full risk of loss from any loss
                  of any nature whatsoever with respect to the Collateral. It
                  shall keep its assets which are of an insurable character
                  insured by financially sound and reputable insurers against
                  loss or damage by fire, explosion and other risks customarily
                  insured against by companies in similar business similarly
                  situated as it; it shall maintain, with financially sound and
                  reputable insurers, insurance against other hazards and risks
                  and liability to persons and property to the extent and in the
                  manner which it thereof reasonably believes is customary for
                  companies in similar business similarly situated as it and to
                  the extent available on commercially reasonable terms. The
                  Company and the Eligible Subsidiaries will cause Laurus to be
                  named as first loss payee or additional insured on all of the
                  policies of insurance relating to the assets pledged to Laurus
                  as security for its obligations hereunder and under the
                  Related Agreements, other than policies of insurance directly
                  related to real property. At its own cost and expense in
                  amounts and with carriers reasonably acceptable to Laurus, it
                  shall (i) keep all their insurable properties and properties
                  in which they have an interest insured against the hazards of
                  fire, flood, sprinkler leakage, those hazards covered by
                  extended coverage insurance and such other hazards, and for
                  such amounts, as is customary in the case of companies engaged
                  in businesses similar to it including business interruption
                  insurance; (ii) maintain a bond in such amounts as is
                  customary in the case of companies engaged in businesses
                  similar to it insuring against larceny, embezzlement or other
                  criminal misappropriation of insured's officers and employees
                  who may either singly or jointly with others at any time have
                  access to its assets or funds either directly or through
                  governmental authority to draw upon such funds or to direct
                  generally the disposition of such assets; (iii) maintain
                  public and product liability insurance against claims for
                  personal injury, death or property damage suffered by others;
                  (iv) maintain all such worker's compensation or similar
                  insurance as may be required under the laws of any province or
                  jurisdiction in which it is engaged in business; and (v)
                  furnish Laurus with (x) copies of all policies and evidence of
                  the maintenance of such policies at least thirty (30) days
                  before any expiration date, (y) excepting its workers'
                  compensation policy, endorsements to such policies naming
                  Laurus as "co-insured" or "additional insured" and appropriate
                  loss payable endorsements in form and substance satisfactory
                  to Laurus, naming Laurus as lenders loss payee, and (z)
                  evidence that as to Laurus the insurance coverage shall not be
                  impaired or invalidated by any act or neglect of the Company
                  and/or any Eligible Subsidiary and the insurer will provide
                  Laurus with at least thirty (30) days notice prior to
                  cancellation. It shall instruct the insurance carriers that in
                  the event of any loss thereunder, the carriers shall make

                                      -25-
<PAGE>

                  payment for such loss to Laurus and not to the Company and/or
                  the Eligible Subsidiaries, as applicable, and Laurus jointly.
                  If any insurance losses are paid by check, draft or other
                  instrument payable to the Company and/and Laurus jointly,
                  Laurus may endorse, as applicable, the Company's and/or the
                  Eligible Subsidiaries' name thereon and do such other things
                  as Laurus may deem advisable to reduce the same to cash.
                  Laurus is hereby authorized to adjust and compromise claims.
                  All loss recoveries received by Laurus upon any such insurance
                  may be applied to the Obligations, in such order as Laurus in
                  its sole discretion shall determine or shall otherwise be

                  Agreements and to carry out their provisions. All corporate
                  action on Laurus' part required for the lawful execution and
                  delivery of this Agreement and the Ancillary Agreements have
                  been or will be effectively taken prior to the Closing Date.
                  Upon their execution and delivery, this Agreement and the
                  Ancillary Agreements shall be valid and binding obligations of
                  Laurus, enforceable in accordance with their terms, except (a)
                  as limited by applicable bankruptcy, insolvency,
                  reorganization, moratorium or other laws of general
                  application affecting enforcement of creditors' rights, and
                  (b) as limited by general principles of equity that restrict
                  the availability of equitable and legal remedies.

         (b)      Investment Representations and Covenants.

                  (i)      Laurus is resident in the jurisdiction of the Cayman

                  (ii)     Laurus is acquiring the Securities for investment
                           only and not with a view to resale or distribution in
                           violation of any securities laws.

                  (iii)    Laurus is not a party to, and is not acting in
                           concert with a person who is party to: (A) an
                           agreement to transfer Laurus' legal or beneficial
                           interest in the Securities; or (B) an agreement to
                           grant a participating interest in the Securities.

                  (iv)     As the Securities purchased hereunder are subject to
                           resale restrictions under the US Securities Act,
                           Laurus shall comply with all securities laws
                           concerning any resale of the Securities purchased
                           hereunder and shall consult with his, her or its own
                           legal advisors with respect to such compliance.

                  (v)      If required by applicable securities laws, Laurus
                           will execute, deliver, file and otherwise assist the
                           Company in filing such reports, undertakings and
                           other documents with respect to the issuance of the
                           Securities as may be required.

                  (vi)     Laurus is purchasing the Securities as principal for
                           its own account and not as a nominee or agent.

                  (vii)    Laurus is an accredited investor within the meaning
                           of Regulation D under the US Securities Act.

                  (viii)   Laurus understands that the Securities are being
                           offered and sold pursuant to an exemption from
                           registration contained in the US Securities Act based
                           in part upon Laurus' representations contained in
                           this Agreement, including, without limitation, that
                           Laurus is an "accredited investor" within the meaning
                           of Regulation D under the US Securities Act.

                  (ix)     Laurus confirms that it has received or has had full
                           access to all the information it considers necessary
                           or appropriate to make an informed investment
                           decision with respect to the Notes and the Warrant to
                           be purchased by it under this Agreement and the
                           Warrant Shares acquired by it upon the exercise of
                           the Warrant. Laurus further confirms that it has had
                           an opportunity to ask questions and receive answers

                           from the Company regarding the Company's and its
                           Subsidiaries' business, management and financial
                           affairs and the terms and conditions of this
                           Agreement, the Notes, the Warrant and the Securities
                           and to obtain additional information (to the extent
                           the Company possessed such information or could
                           acquire it without unreasonable effort or expense)
                           necessary to verify any information furnished to
                           Laurus or to which Laurus had access.

                  (x)      Laurus understands that the Securities have not been
                           and will not be registered under the US Securities
                           Act or any applicable state securities laws and that
                           the sale contemplated hereby is being made in
                           reliance on an exemption from registration therefrom.

                  (xi)     Laurus acknowledges that Laurus has not purchased the
                           Securities as a result of any general solicitation or
                           general advertising (as those terms are used in
                           Regulation D), including advertisements, articles,
                           notices or other communications published in any
                           newspaper, magazine or similar media, or broadcast
                           over radio, television or other forms of
                           telecommunication, including electronic display (such
                           as the Internet), or any seminar or meeting whose
                           attendees have been invited by general solicitation
                           or general advertising.

                  (xii)    Laurus has substantial experience in evaluating and
                           investing in private placement transactions of
                           securities in companies similar to the Company so
                           that it is capable of evaluating the merits and risks
                           of its investment in the Company and has the capacity
                           to protect its own interests. Laurus must bear the
                           economic risk of this investment until the Securities
                           are sold.

                  (xiii)   By reason of its, or of its management's business and
                           financial experience, Laurus has the capacity to
                           evaluate the merits and risks of its investment in
                           the Notes, the Warrant, and the Securities and to
                           protect its own interests in connection with the
                           transactions contemplated in this Agreement and the
                           Related Agreements.

                  (xiv)    In the event that Laurus becomes an "insider" or
                           "control person" of the Company (within the meaning
                           of applicable securities laws) or in the event that a
                           nominee of Laurus becomes a director or officer of
                           the Company or any of its Subsidiaries, Laurus shall
                           notify the Principal Market thereof and shall file
                           with the Principal Market any personal information
                           forms required by reason thereof.

         (c)      Shorting. Neither Laurus nor any of its Affiliates or
                  investment partners has, will, or will cause any Person, to
                  directly engage in "short sales" of the Company's Common Stock
                  as long as the Notes shall be outstanding.

         (d)      Patriot Act. Laurus certifies that, to the best of Laurus'
                  knowledge, Laurus has not been designated, and is not owned or
                  controlled, by a "suspected terrorist" as defined in Executive
                  Order 13224. Laurus seeks to comply with all applicable laws
                  concerning money laundering and related activities. In
                  furtherance of those efforts, Laurus hereby represents,
                  warrants and covenants that: (i) none of the cash or property
                  that Laurus will use to make the Loans has been or shall be
                  derived from, or related to, any activity that is deemed
                  criminal under United States law; and (ii) no disbursement by
                  Laurus to the Company to the extent within Laurus' control,
                  shall cause Laurus to be in violation of the United States

                  International Money Laundering Abatement and Anti-Terrorist
                  Financing Act of 2001 or the Canadian Proceeds of Crime (Money
                  Laundering and Terrorist Financing Act. Laurus shall promptly
                  notify the Company if any of these representations ceases to
                  be true and accurate regarding Laurus. Laurus agrees to
                  provide the Company any additional information regarding
                  Laurus that the Company deems necessary or convenient to
                  ensure compliance with all applicable laws concerning money
                  laundering and similar activities. Laurus understands and
                  agrees that if at any time it is discovered that any of the
                  foregoing representations are incorrect, or if otherwise
                  required by applicable law or regulation related to money
                  laundering similar activities, Laurus may undertake
                  appropriate actions to ensure compliance with applicable law
                  or regulation, including but not limited to segregation and/or
                  redemption of Laurus' investment in the Company. Laurus
                  further understands that the Company may release information
                  about Laurus and, if applicable, any underlying beneficial
                  owners, to proper authorities if the Company, in its sole
                  discretion, determines that it is in the best interests of the
                  Company in light of relevant rules and regulations under the
                  laws set forth in subsection (ii) above.

22.      Power of Attorney.

         In the event of an Event of Default which is continuing, each of the
Company and the Eligible Subsidiaries hereby appoints Laurus, or any other
Person whom Laurus may designate as the Company's and the Eligible Subsidiary's
attorney, with power to: (i) endorse the Company's and/or the Eligible
Subsidiary's name on any checks, notes, acceptances, money orders, drafts or
other forms of payment or security that may come into Laurus' possession; (ii)
sign the Company's and/or the Eligible Subsidiary's name on any invoice or bill
of lading relating to any Accounts, drafts against Account Debtors, schedules

Company and the Eligible Subsidiary hereby ratifies and approves all acts of the
attorney. Neither Laurus, nor the attorney will be liable for any acts or
omissions or for any error of judgment or mistake of fact or law, except for
gross negligence or wilful misconduct. This power, being coupled with an
interest, is irrevocable so long as Laurus has a security interest and until the
Obligations have been fully satisfied.

23.      Term of Agreement.

         Laurus' agreement to make Loans and extend financial accommodations as
promptly as practicable but no longer than 15 days, under and in accordance with
the terms of this Agreement or any Ancillary Agreement shall continue in full
force and effect until the expiration of the Term. At Laurus' election following
the occurrence of an Event of Default which is continuing, Laurus may terminate

rights hereunder or any Ancillary Agreement and the provisions hereof and
thereof shall continue to be fully operative until all transactions entered
into, rights or interests created and the Obligations have been irrevocably
disposed of, concluded or liquidated. Notwithstanding the foregoing, Laurus
shall release its security interests at any time after thirty (30) days notice
upon irrevocable payment to it of all Obligations if the Company shall have

                  pursuant to the terms hereof, or in connection with the
                  transactions contemplated by this Agreement should prove to be

26.      Remedies.

         (a)      Following the occurrence of an Event of Default which is
                  continuing, Laurus shall have the right to demand repayment in
                  full of all Obligations, whether or not otherwise due. Until
                  all Obligations have been fully and indefeasibly satisfied,
                  Laurus shall retain its Lien in all Collateral. Laurus shall
                  have, in addition to all other rights provided herein and in
                  each Ancillary Agreement, all of the rights and remedies of a
                  secured creditor under the PPSA, and any remedies as a secured
                  creditor under any other applicable law, and all other legal
                  and equitable rights to which Laurus may be entitled.

27.      Waivers.

         To the full extent permitted by applicable law, the Company and each
Eligible Subsidiary hereby waives (a) presentment, demand and protest, and
notice of presentment, dishonour, intent to accelerate, acceleration, protest,
default, non-payment, maturity, release, compromise, settlement, extension or
renewal of any or all of this Agreement and the Ancillary Agreements or any
other notes, commercial paper, Accounts, contracts, Documents and guaranties at
any time held by Laurus on which the Company and/or the Eligible Subsidiary may
in any way be liable, and hereby ratifies and confirms whatever Laurus may do in
this regard; (b) all rights to notice and a hearing prior to Laurus' taking
possession or control of, or to Laurus' replevy, attachment or levy upon, any
Collateral or any bond or security that might be required by any court prior to
allowing Laurus to exercise any of its remedies; and (c) the benefit of all
valuation, appraisal and exemption laws. The Company and the Eligible Subsidiary
acknowledge that it has been advised by counsel of its choices and decisions
with respect to this Agreement, the Ancillary Agreements and the transactions
evidenced hereby and thereby.

28.      Expenses.

         The Company shall pay all of Laurus' out-of-pocket costs and expenses,
including reasonable fees and disbursements of in-house or outside counsel and
appraisers, in connection with the preparation, execution and delivery of this
Agreement and the Ancillary Agreements, and in connection with the prosecution
or defense of any action, contest, dispute, suit or proceeding concerning any
matter in any way arising out of, related to or connected with this Agreement or
any Ancillary Agreement. The Company shall also pay all of Laurus' reasonable
fees, charges, out-of-pocket costs and expenses, including fees and
disbursements of counsel and appraisers, in connection with (a) the preparation,
execution and delivery of any waiver, any amendment thereto or consent proposed
or executed in connection with the transactions contemplated by this Agreement
or the Ancillary Agreements, (b) Laurus' obtaining performance of the
Obligations under this Agreement and any Ancillary Agreements, including, but
not limited to, the enforcement or defense of Laurus' security interests,
assignments of rights and Liens hereunder as valid perfected security interests,
(c) any attempt to inspect, verify, protect, collect, sell, liquidate or
otherwise dispose of any Collateral, (d) any appraisals or reappraisals of any
property (real or personal) pledged to Laurus by the Company as Collateral for,
or any other Person as security for, the Obligations hereunder and (e) any
consultations in connection with any of the foregoing. The Company shall also
pay Laurus' customary bank charges for all bank services (including wire
transfers) performed or caused to be performed by Laurus for the Company at the
Company's request or in connection with the Company's loan account with Laurus.
All such costs and expenses together with all filing, recording and search fees,
taxes and interest payable by the Company to Laurus shall be payable on demand
and shall be secured by the Collateral. If any tax by any Governmental Authority
is or may be imposed on or as a result of any transaction between the Company
and Laurus on the other hand, which Laurus is or may be required to withhold or
pay, the Company indemnifies and holds Laurus harmless in respect of such taxes,
and the Company will repay to Laurus the amount of any such taxes which shall be

                                      -35-
<PAGE>

charged to the Company's account; and until the Company shall furnish Laurus
with indemnity therefor (or supply Laurus with evidence satisfactory to it that
due provision for the payment thereof has been made), Laurus may hold without
interest any balance standing to the Company's credit and Laurus shall retain
its Liens in any and all Collateral.

29.      Assignment By Laurus.

         Prior to an Event of Default, Laurus may assign any or all of the
Obligations together with any or all of the security therefor to any Person
which is not a competitor of the Company and any such transferee shall succeed
to all of Laurus' rights with respect thereto.

         Upon the occurrence of an Event of Default, Laurus may assign any or
all of the Obligations together with any or all of the security therefor to any
Person, without restriction, and any such transferee shall succeed to all of
Laurus' rights with respect thereto.

         Upon such transfer, either prior to or upon the occurrence of the Event
of Default, as the case may be, Laurus shall be released from all responsibility
for the Collateral to the extent same is assigned to any transferee. Laurus may
from time to time sell or otherwise grant participations in any of the
Obligations and the holder of any such participation shall, subject to the terms
of any agreement between Laurus and such holder, be entitled to the same
benefits as Laurus with respect to any security for the Obligations in which
such holder is a participant. The Company agrees that each such holder may
exercise any and all rights of banker's lien, set-off and counterclaim with
respect to its participation in the Obligations as fully as though the Company
were directly indebted to such holder in the amount of such participation.

30.      No Waiver; Cumulative Remedies.

         Failure by Laurus to exercise any right, remedy or option under this
Agreement, any Ancillary Agreement or any supplement hereto or thereto or any
other agreement between or among the Company and Laurus or delay by Laurus in
exercising the same, will not operate as a waiver; no waiver by Laurus will be
effective unless it is in writing and then only to the extent specifically
stated. Laurus' rights and remedies under this Agreement and the Ancillary
Agreements will be cumulative and not exclusive of any other right or remedy
which Laurus may have.

31.      Application of Payments.

         The Company irrevocably waive the right to direct the application of
any and all payments at any time or times hereafter received by Laurus from or
on the Company's behalf and the Company hereby irrevocably agrees that Laurus
shall have the continuing exclusive right to apply and reapply any and all
payments received at any time or times hereafter against the Obligations
hereunder in such manner as Laurus may deem advisable notwithstanding any entry
by Laurus upon any of Laurus' books and records.

32.      Indemnity.

         The Company hereby indemnifies and holds Laurus, and its respective
affiliates, employees, attorneys and agents (each, an "Indemnified Person"),
harmless from and against any and all suits, actions, proceedings, claims,
damages, losses, liabilities and expenses of any kind or nature whatsoever
(including legal fees and disbursements and other costs of investigation or
defense, including those incurred upon any appeal) which may be instituted or
asserted against or incurred by any such Indemnified Person as the result of
credit having been extended, suspended or terminated under this Agreement or any
of the Ancillary Agreements or with respect to the execution, delivery,
enforcement, performance and administration of, or in any other way arising out
of or relating to, this Agreement, the Ancillary Agreements or any other

                                      -36-
<PAGE>

documents or transactions contemplated by or referred to herein or therein and
any actions or failures to act with respect to any of the foregoing, except to
the extent that any such indemnified liability is finally determined by a court
of competent jurisdiction to have resulted solely from such Indemnified Person's
gross negligence or wilful misconduct. NO INDEMNIFIED PERSON SHALL BE
RESPONSIBLE OR LIABLE TO ANY COMPANY OR TO ANY OTHER PARTY OR TO ANY SUCCESSOR,
ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER PERSON ASSERTING CLAIMS
DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR
CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN
EXTENDED, SUSPENDED OR TERMINATED UNDER THIS AGREEMENT OR ANY ANCILLARY
AGREEMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR
THEREUNDER.

33.      Revival.

         The Company further agree that to the extent the Company makes a
payment or payments to Laurus, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy act, state, provincial or federal law, common law or equitable cause,
then, to the extent of such payment or repayment, the obligation or part thereof
intended to be satisfied shall be revived and continued in full force and effect
as if said payment had not been made.

34.      Notices.

         Any notice or request hereunder may be given to the Company or Laurus
at the respective addresses set forth below or as may hereafter be specified in
a notice designated as a change of address under this Section. Any notice or
request hereunder shall be given by registered or certified mail, return receipt

         (a)      THIS AGREEMENT AND THE ANCILLARY AGREEMENTS SHALL BE GOVERNED
                  BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF
                  THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND
                  PERFORMED IN SUCH STATE, WITHOUT REGARD TO PRINCIPLES OF
                  CONFLICTS OF LAW.

         (b)      EACH COMPANY HEREBY CONSENTS AND AGREES THAT THE STATE OR
                  FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW
                  YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE
                  ANY CLAIMS OR DISPUTES BETWEEN ANY COMPANY, ON THE ONE HAND,
                  AND LAURUS, ON THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR
                  ANY OF THE ANCILLARY AGREEMENTS OR TO ANY MATTER ARISING OUT
                  OF OR RELATED TO THIS AGREEMENT OR ANY OF THE ANCILLARY

                                      -38-
<PAGE>

                  ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS TO TRIAL BY
                  JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY
                  DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE
                  BETWEEN LAURUS, AND/OR ANY COMPANY ARISING OUT OF, CONNECTED
                  WITH, RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
                  BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, ANY ANCILLARY
                  AGREEMENT OR THE TRANSACTIONS RELATED HERETO OR THERETO.

36.      Judgment Currency.

         If, for the purpose of obtaining or enforcing judgment against the
Company in any court in any jurisdiction, it becomes necessary to convert into
any other currency (such other currency being hereinafter in this section
referred to as the "Judgment Currency") an amount due under this Security
Agreement in any currency (the "Obligation Currency") other than the Judgment
Currency, the conversion shall be made at the rate of exchange prevailing on the
business day immediately preceding (a) the date of actual payment of the amount
due, in the case of any proceeding in the courts of New York or in the courts of
any other jurisdiction that will give effect to such conversion being made on
such date, or (b) the date on which the foreign court determines, in the case of
any proceeding in the courts of any other jurisdiction (the applicable date as
of which such conversion is made pursuant to this section being hereinafter in
this section referred to as the "Judgment Conversion Date").

         If, in the case of any proceeding in the court of any jurisdiction
referred to in the preceding paragraph, there is a change in the rate of
exchange prevailing between the Judgment Conversion Date and the date of actual
receipt of the amount due in immediately available funds, the Company shall pay
such additional amount (if any, but in any event not a lesser amount) as may be
necessary to ensure that the amount actually received in the Judgment Currency,
when converted at the rate of exchange prevailing on the date of payment, will
produce the amount of the Obligation Currency which could have been purchased
with the amount of the Judgment Currency stipulated in the judgment or judicial
order at the rate of exchange prevailing on the Judgment Conversion Date. Any
amount due from the Company under this section shall be due as a separate debt
and shall not be affected by judgment being obtained for any other amounts due
under or in respect of this Security Agreement.

37.      Limitation of Liability.

         The Company acknowledges and understands that in order to assure
repayment of the Obligations hereunder Laurus may be required to exercise any
and all of Laurus' rights and remedies hereunder and agrees that, except as
limited by applicable law, neither Laurus nor any of Laurus' agents shall be
liable for acts taken or omissions made in connection herewith or therewith
except for actual bad faith.

38.      Entire Understanding; Maximum Interest.

         This Agreement and the Ancillary Agreements contain the entire
understanding among the Company and Laurus as to the subject matter hereof and
thereof and any promises, representations, warranties or guarantees not herein
contained shall have no force and effect unless in writing, signed by the
Company's and Laurus' respective officers. Neither this Agreement, the Ancillary
Agreements, nor any portion or provisions thereof may be changed, modified,
amended, waived, supplemented, discharged, cancelled or terminated orally or by
any course of dealing, or in any manner other than by an agreement in writing,
signed by the party to be charged. Nothing contained in this Agreement, any
Ancillary Agreement or in any document referred to herein or delivered in
connection herewith shall be deemed to establish or require the payment of a

                                      -39-
<PAGE>

rate of interest or other charges in excess of the maximum rate permitted by
applicable law. In the event that the rate of interest or dividends required to
be paid or other charges hereunder exceed the maximum rate permitted by such
law, any payments in excess of such maximum shall be credited against amounts
owed by the Company to Laurus and thus refunded to the Company.

39.      Severability.

         Wherever possible each provision of this Agreement or the Ancillary
Agreements shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement or the Ancillary
Agreements shall be prohibited by or invalid under applicable law such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions
thereof.

40.      Survival.

         The representations, warranties, covenants and agreements made herein
shall survive any investigation made by Laurus and the closing of the
transactions contemplated hereby to the extent provided therein. All statements
as to factual matters contained in any certificate or other instrument delivered
by or on behalf of the Company pursuant hereto in connection with the
transactions contemplated hereby shall be deemed to be representations and
warranties by the Company hereunder solely as of the date of such certificate or
instrument. All indemnities set forth herein shall survive the execution,
delivery and termination of this Agreement and the Ancillary Agreements and the
making and repaying of the Obligations.

41.      Captions.

         All captions are and shall be without substantive meaning or content of
any kind whatsoever.

42.      Counterparts; Telecopier Signatures.

         This Agreement may be executed in one or more counterparts, each of
which shall constitute an original and all of which taken together shall
constitute one and the same agreement. Any signature delivered by a party via
telecopier transmission shall be deemed to be any original signature hereto.

43.      Construction.

         The parties acknowledge that each party and its counsel have reviewed
this Agreement and that the normal rule of construction to the effect that any
ambiguities are to be resolved against the drafting party shall not be employed
in the interpretation of this Agreement or any amendments, schedules or exhibits
thereto.

44.      Publicity.

         The Company hereby authorizes Laurus to make appropriate announcements
of the financial arrangement entered into by and among the Company and Laurus,
including, without limitation, announcements which are commonly known as
tombstones, in such publications and to such selected parties as Laurus shall in
its sole and absolute discretion deem appropriate, or as required by applicable
law.

45.      Joinder.

         It is understood and agreed that any Person that desires to become a
party hereunder, or is required to execute a counterpart of this Agreement after
the date hereof pursuant to the requirements of this Agreement or any Ancillary

                                      -40-
<PAGE>

Agreement, shall become a party hereunder by (a) executing a Joinder Agreement
in form and substance satisfactory to Laurus, (b) delivering supplements to such
exhibits and annexes to this Agreement and the Ancillary Agreements as Laurus
shall reasonably request and (c) taking all actions as specified in this
Agreement as would have been taken by the Company and the Eligible Subsidiaries
had it been an original party to this Agreement, in each case with all documents
required above to be delivered to Laurus and with all documents and actions
