 3. REPRESENTATIONS AND WARRANTIES OF BORROWER

         Borrower represents and warrants to Lenders as follows:

         3.1 Locations. Schedule 3.1 hereto lists the addresses of the (a) chief
executive offices of Borrower and the place where Borrower keeps its records
concerning the Collateral and all originals of all chattel paper included in the
Collateral and (b) the location of substantially all of the other Collateral
(collectively, the "Premises")

         3.2 Perfection and Priority of Liens. Upon the execution and delivery
hereof, this Agreement shall have created a valid lien in all of the Collateral
in favor of Lenders, subject to no prior or superior liens other than the liens
permitted under Section 4.1 hereof.

         3.3 Title to Collateral. Borrower is and shall continue to be, so long
as the Secured Indebtedness shall be unpaid, the sole owner of the Collateral
free and clear of all liens, encumbrances, security interests, and claims,
except for (a) the liens and security interests granted herein and (b) liens
permitted under Section 4.1 hereof, with full



                                       6
<PAGE>   7


power and authority to sell, transfer, pledge and grant to Lenders a security
interest in each and every item of the Collateral.

         3.4 Organization and Qualification. Borrower is a corporation
organized, validly existing and in good standing under the laws of Delaware, and
is duly qualified to do business and is in good standing in each state in which
the failure to be so qualified or in good standing would have a material adverse
effect on the business, operations, properties or condition (financial or other)
of Borrower.

         3.5 Authorization. The execution, delivery, and performance by Borrower
of each of the Loan Documents to which Borrower is a party are within Borrower's
corporate powers, and have been duly authorized by all necessary corporate
action. Each of the Loan Documents to which Borrower is a party constitutes the
legal, valid, and binding obligation of Borrower enforceable against Borrower in
accordance with its terms. Borrower has authorized and reserved for issuance
2,600,000 shares of Common Stock upon conversion of the Notes. All shares of
Common Stock issuable upon conversion of the Notes shall, when issued, by duly
and validly issued, fully paid and non-assessable and free from all taxes, liens
and charges.

         3.6 No Conflict. Neither Borrower's execution and delivery of, nor its
performance under any of the Loan Documents does or will (a) contravene,
conflict with, or violate (i) the Certificate of Incorporation or bylaws of
Borrower, or (ii) any law, rule, regulation, order, writ, judgment, injunction,
decree, determination or award presently in effect having applicability to it,
or (b) contravene, conflict with or violate in any material respect, or (with or
without the passage of time or giving of notice, or both) constitute or result
in a breach or default under any indenture or loan or credit agreement or any
other material agreement, lease or instrument to which it is a party or by which
it or its properties may be bound or affected.

         3.7 Approvals. No authorization or approval or other action by, and no
notice to or filing with any governmental authority or regulatory body or any
other person is required to be obtained or made by Borrower for the due
execution, delivery, and performance of any of the Loan Documents to which it is
a party, except for the consent of CFC pursuant to the Congress Loan Agreement,
and the consents of third parties to certain leases and agreements in which
Borrower is granting a security interest hereunder.

         3.8 Actions Pending. There is no action or proceeding pending or, to
the knowledge of Borrower, threatened against Borrower or any of its properties
or rights before any court or governmental or administrative instrumentality
which, if determined adversely to Borrower, could reasonably be expected to
result in a material adverse change in its ability to perform its obligations
under the Loan Documents to which it is a party or its financial condition or
operations, business, or properties taken as a whole.

         3.9 Accounts. Borrower is the true and lawful owner of the Accounts,
and has, or at the time each Account comes into existence will have, good and
clear title to each Account, subject to the rights of CFC and Lenders thereto.
Each Account is, or at the



                                       7
<PAGE>   8


time it comes into existence will be, (i) a valid obligation of the account
debtor enforceable in accordance with its terms, and to the best of Borrower's
knowledge and belief, free and clear of all liens, security interests,
restrictions, set-offs, adverse claims, assessments, defaults, prepayments,
defenses and conditions precedent other than the security interest created and
granted hereby, and (ii) a true and correct statement of the account for
merchandise actually sold and delivered to, or for actual services performed for
and accepted by, such account debtor.

         3.10 Solvency. On the date hereof and after giving effect to the
Secured Indebtedness created by the Notes, on a consolidated basis, the fair
saleable value of the property of Borrower on a going concern basis is greater
that the total amount of liabilities (including contingent and unliquidated
liabilities) of Borrower on the date hereof. In computing the amount of
contingent or liquidated liabilities at any time, such liabilities will be
computed at the amount which, in light of all the facts and circumstances
existing at such time, represents the amount that can reasonably be expected to
become an actual or matured liability.

         3.11 Representations in Merger Agreement. The representations and
warranties of Borrower contained in the Merger Agreement (as modified by the
Disclosure Memorandum, as defined in the Merger Agreement) (a) that are
expressly qualified by a reference to materiality are true in all respects as so
qualified as of the date hereof and (b) that are not so qualified are true and
correct in all material respects as of the date hereof, and are incorporated
herein by reference with the same force and effect as though herein set forth in
full. Notwithstanding the foregoing, the condition set forth in this Section
3.11 shall be deemed to be satisfied if such breaches of Borrower's
representations and warranties (if any) do not have a Parent Material Adverse
Effect (as defined in the Merger Agreement) or a material diminution of benefits
expected to be realized by Ecrix as a result of the Merger.

 4. COVENANTS OF BORROWER

         4.1 Encumbrances. Borrower shall not create, incur, assume or suffer to

condition of Borrower and its subsidiaries as of the end of and for the fiscal
year then ended.

                (b) Borrower shall promptly notify Lenders in writing of the
details of (i) any loss, damage, investigation, action, suit, proceeding or

furnish or cause to be furnished to Lenders copies of all reports which Borrower
sends to its stockholders generally and copies of all reports and registration

Inc.

                (d) Borrower shall furnish or cause to be furnished to Lenders
such budgets, forecasts, projections and other information respecting the
Collateral and the business of Borrower, as Lenders may, from time to time,
reasonably request. Lenders are hereby authorized to deliver a copy of any
financial statement or any other information relating to the business of
Borrower to any court or other government agency or, upon prior written notice
to Borrower or upon obtaining an agreement from such Person to maintain the
confidentiality of such information, to any participant or assignee or
prospective participant or assignee. Borrower hereby irrevocably authorizes and
directs all accountants or auditors to deliver to Lenders, at Borrower's
expense,



                                       11
<PAGE>   12


copies of the financial statements of Borrower and any reports or management
letters prepared by such accountants or auditors on behalf of Borrower and to
disclose to Lenders such information as they may have regarding the business of
Borrower. Any documents, schedules, invoices or other papers delivered to
Lenders may be destroyed or otherwise disposed of by Lenders one (1) year after
the same are delivered to Lenders, except as otherwise designated by Borrower to
Lenders in writing.

         4.7 Location of Offices; Inspection. Borrower shall keep its chief
executive offices and the office where it keeps its records concerning the
Collateral and all originals of all chattel paper included in the Collateral at
the locations specified in Section 3.1 or, upon 30 days' prior written notice to
Lenders, at locations in a jurisdiction in which all action required by Section
4.8 shall have been taken with respect to the Collateral. Borrower shall hold
and preserve such records and chattel paper and permit representatives of
Lenders at any time during Borrower's normal business hours to inspect and make
abstracts from and copies of such records and chattel paper.

         4.8 Further Assurances.

                (a) Further Actions. Borrower shall from time to time, at its
sole expense, promptly execute and deliver all further instruments and
documents, and take all further actions, as may be necessary and desirable, or
that a Majority of Lenders may reasonably request, in order to perfect and
protect any security interest granted or purported to be granted hereby, or to
enable Lenders to exercise and enforce their rights and remedies hereunder with
respect to any Collateral. Without limiting the generality of the foregoing,
Borrower shall execute and file such financing or continuation statements, or
amendments thereto, and such other instruments or notices as a Majority of
Lenders may request, in order to perfect and preserve the security interests
granted or purported to be granted hereby.

                (b) Financing Statements. Borrower authorizes Lenders to file
without the signature of Borrower (where permitted by law) one or more financing
or continuation statements, and amendments thereto, relative to all or any part
of the Collateral. A carbon, photographic or other reproduction of this
Agreement or any financing statement covering the Collateral or any part thereof
shall be sufficient as a financing statement where permitted by law.

         4.9 Insurance. Borrower shall, at its own expense, at all times
maintain with financially sound reputable insurers insurance with respect to the
Equipment and Inventory in such amounts, against such risks and in amounts
customarily insured against or carried by entities of established reputation
engaged in the same or similar businesses and similarly situated. Borrower shall
furnish certificates or endorsements to Lenders as a Majority of Lenders shall
require as proof of such insurance, and, if Borrower fails to do so, Lenders are
authorized, but not required, to obtain such insurance at the expense of
Borrower. All policies shall provide for at least thirty (30) days' prior
written notice to Lenders of any cancellation or reduction of coverage. Borrower
shall cause Lenders to be named as a loss payee and an additional insured under
such insurance policies. At its option, Lenders may apply any insurance proceeds
received



                                       12
<PAGE>   13


by Lenders at any time to the cost of repairs or replacement of Collateral
and/or to payment of the Secured Indebtedness, whether or not then due, in any
order and in such manner as a Majority of Lenders may determine or hold such
proceeds as cash collateral for the Secured Indebtedness.

         4.10 Equipment and Inventory.  Borrower shall:

                (a) Keep the Equipment and Inventory (other than Inventory sold
in the ordinary course of business) at the places therefor specified in
Section 3.1.

                (b) Cause the Equipment to be maintained and preserved in good
condition, repair and working order, ordinary wear and tear excepted.

                (c) Pay promptly when due all property and other taxes,
assessments and governmental charges or levies imposed upon, and all claims
(including claims for labor, materials and supplies) against, the Equipment and
Inventory, except to the extent the validity thereof is being contested in good
faith by appropriate proceedings, and adequate reserves for payment thereof are
maintained.

         4.11 Accounts.

                (a) Collection of Accounts. Borrower is authorized to collect
the Accounts at no cost or expense to Lenders, subject to the rights of Lenders
to collect the Accounts as hereinafter provided, and Borrower shall collect with
diligence all Accounts. Upon the occurrence of an Event of Default which is
continuing, Borrower shall, if so directed by a Majority of Lenders, advise
account debtors to make all future remittances and payments to a post office box
maintained under the sole and absolute control of Lenders. Notwithstanding and
in addition to the foregoing, Lenders shall have the right at any time, upon the
occurrence of an Event of Default which is continuing, upon written notice to
Borrower of their intention to do so, to notify the account debtors or obligors
under any Accounts of the assignment of such Accounts to Lenders and to direct
such account debtors or obligors to make payment of all amounts due or to become
due to Borrower thereunder directly to Lenders and, upon such notification and
at the expense of Borrower, to enforce collection of any such Accounts, and to
adjust, settle or compromise the amount of payment thereof, in the same manner
and to the same extent as Borrower might have done.

 5. CERTAIN RIGHTS OF LENDERS

         5.1 Lenders as Attorney-in-Fact. Effective upon the occurrence of an
Event of Default which is continuing, Borrower hereby irrevocably appoints
Meritage Private Equity Fund, L.P. ("MPEF"), on behalf of the Lenders, as
Borrower's attorney-in-fact, such appointment coupled with an interest, with
full authority in the place and stead of Borrower and in the name of Borrower,
Lenders or otherwise, from time to time in MPEF's discretion, to take any action
and to execute any instrument which Lenders may deem necessary or advisable to
accomplish the purposes of this Agreement, including but not limited to the
following:

proceedings which Lenders may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce the rights of Lenders with respect
to any of the Collateral.

         5.2 Lenders May Perform. If Borrower shall fail to perform any covenant
or obligation contained herein or in any of the Loan Documents, MPEF, on behalf
of the Lenders, may itself perform, or cause performance of, such covenant or
obligation and the reasonable expenses of MPEF incurred in connection therewith
shall be payable by Borrower under Section 8.2.

 6. EVENTS OF DEFAULT

         The occurrence of any of the following shall constitute an "Event of
Default" hereunder:

                (a) Monetary Default. Borrower shall fail to pay (i) any
installment of principal when due or (ii) any installment of interest under any
Note when due and such failure to pay is not cured within 5 days after such
failure.

                (b) Default of Covenants. Borrower shall fail or refuse to
perform any covenant or obligation stated in this Agreement or in any other Loan
Document, other than monetary obligations or covenants described in paragraph

notice by a Lender to Borrower of such default.

                (c) Judgments. Any judgment for the payment of money is rendered

in the aggregate and shall remain undischarged or unvacated for a period in
excess of 30 days or execution shall at any time not be effectively stayed, or
any judgment other than for the payment of money, or injunction, attachment,
garnishment or execution with respect to any judgment or judgments in excess of
the above amounts is rendered against Borrower or any of its assets.

                (d) Voluntary Insolvency. Borrower shall commence (by petition,
application, or otherwise) a voluntary case or other proceeding under the laws
of any jurisdiction seeking liquidation, reorganization, or other relief with
respect to itself or its debts under any bankruptcy, insolvency, or other
similar law now or hereafter in effect, or seeking the appointment of a trustee,
self-trusteeship, receiver, custodian, or



                                       14
<PAGE>   15


other similar official of it or any substantial part o fits property, or shall
consent (by answer or failure to answer or otherwise) to any such relief or to
the appointment of or taking possession by any such official in an involuntary
case or other proceeding commenced against it, or shall make an assignment for
the benefit of creditors, or shall generally not pay its debts as they become
due, or shall admit in writing its inability to pay its debts as they become
due, or shall take any action to authorize any of the foregoing.

                (e) Involuntary Insolvency. An involuntary case or other
proceeding shall be commenced under the laws of any jurisdiction against
Borrower seeking liquidation, reorganization, or other relief with respect to it
or its debts under any bankruptcy, insolvency, or other similar law now or
hereafter in effect, or seeking the appointment of a trustee, receiver,
custodian, or other similar official of it or any substantial part of its
property, and such involuntary case or other proceeding shall remain undismissed
and unstayed for a period of 60 days, or a trustee, receiver, custodian, or
other similar official shall be appointed in such involuntary case.

                (f) False Representations. Any of the representations or
warranties contained in this Agreement or in any other Loan Document shall be or
have been false, misleading, or untrue in any material respect when made or when
otherwise required by the terms of any Loan Document to be true and accurate.

                (g) Default under Other Indebtedness. Other than with respect to
accounts payable of Borrower which are overdue on the date hereof, the default
or the happening of any event shall occur under any indenture, agreement or
other instrument under which indebtedness for borrowed money (other than the
Loans) of Borrower or any of its subsidiaries having an aggregate principal
amount of $330,000 or more has been or may be issued and such default or event
shall continue for a period of time sufficient to permit the acceleration of the
maturity of such indebtedness of Borrower or any of its subsidiaries outstanding
thereunder.

 7. REMEDIES

         7.1 Remedies Nonexclusive. At any time an Event of Default exists or
has occurred and is continuing, Lenders shall have all rights and remedies
provided in this Agreement, the other Loan Documents, the Uniform Commercial
Code as in effect in the State of Colorado (the "UCC") and other applicable law,
all of which rights and remedies may be exercised without notice to or consent
by Borrower, except as such notice or consent is expressly provided for
hereunder or required by applicable law. All rights, remedies and powers granted
to Lenders hereunder, under any of the other Loan Documents, the UCC or other
applicable law, are cumulative, not exclusive and enforceable, in Lenders'
discretion, alternatively, successively, or concurrently on any one or more
occasions, and shall include, without limitation, the right to apply to a court
of equity for an injunction to restrain a breach or threatened breach by
Borrower of this Agreement or any of the other Loan Documents. Lenders may, at
any time or times, proceed directly against Borrower to collect the Secured
Indebtedness without prior recourse to the Collateral.


                                       15
<PAGE>   16


         7.2 Acceleration and Remedies.

                (a) Without limiting the foregoing, at any time an Event of
Default exists or has occurred and is continuing, a Majority of Lenders may, in
their discretion and without limitation, (i) accelerate the payment of all
Secured Indebtedness and demand immediate payment thereof to Lenders (provided,
that, upon the occurrence of any Event of Default described in Sections 6.1(d)
or 6.1(e), all Secured Indebtedness shall automatically become immediately due
and payable), (ii) with or without judicial process or the aid or assistance of
others, enter upon any premises on or in which any of the Collateral may be
located and take possession of the Collateral or complete processing,
manufacturing and repair of all or any portion of the Collateral, (iii) require
Borrower, at Borrower's expense, to assemble and make available to Lenders any
part or all of the Collateral at any place and time designated by a Majority of
Lenders, (iv) collect, foreclose, receive, appropriate, setoff and realize upon
any and all Collateral, (v) remove any or all of the Collateral from any
premises on or in which the same may be located for the purpose of effecting the
sale, foreclosure or other disposition thereof or for any other purpose, (vi)
sell, lease, transfer, assign, deliver or otherwise dispose of any and all
Collateral (including entering into contracts with respect thereto, public or
private sales at any exchange, broker's board, at any office of Lenders or
elsewhere) at such prices or terms as a Majority of Lenders may deem reasonable,
for cash, upon credit or for future delivery, with Lenders having the right to
purchase the whole or any part of the Collateral at any such public sale, all of
the foregoing being free from any right or equity of redemption of Borrower,
which right or equity of redemption is hereby expressly waived and released by
Borrower and/or (vii) terminate this Agreement. If any of the Collateral is sold
or leased by Lenders upon credit terms or for future delivery, the Secured
Indebtedness shall not be reduced as a result thereof until payment therefor is
finally collected by Lenders. If notice of disposition of Collateral is required
by law, five (5) days prior notice by a Lender to Borrower designating the time
and place of any public sale or the time after which any private sale or other
intended disposition of Collateral is to be made, shall be deemed to be
reasonable notice thereof and Borrower waives any other notice. In the event
Lenders institute an action to recover any Collateral or seek recovery of any
Collateral by way of prejudgment remedy, Borrower waives the posting of any bond
which might otherwise be required.

                (b) Lenders may apply the cash proceeds of Collateral actually
received by Lenders from any sale, lease, foreclosure or other disposition of
the Collateral to payment of the Secured Indebtedness, in whole or in part and
in such order as a Majority of Lenders may elect, whether or not then due.
Borrower shall remain liable to Lenders for the payment of any deficiency with
interest at the highest rate provided for herein and all costs and expenses of
collection or enforcement, including reasonable attorneys' fees and legal
expenses.

                (c) Without limiting the foregoing, upon the occurrence of an
Event of Default which is continuing, each Lender may, at its option, without
notice, (i) cease making Loans to Borrower and/or (ii) terminate, as to such
Lender, any provision of this Agreement providing for any future Loans to be
made by such Lender to Borrower.


                                       16
<PAGE>   17


         7.3 Limitation on Duty of Lenders with Respect to Collateral. Beyond
the safe custody thereof or as otherwise required by applicable law, Lenders
shall have no duty with respect to any Collateral in the possession or control
of the Lenders (or in the possession or control of any agent or bailee) or with
respect to any income thereon or the preservation of rights against prior
parties or any other rights pertaining thereto. Lenders shall not be liable or
responsible for any loss or damage to any of the Collateral, or for any
diminution in the value thereof, other than as a result of Lenders' gross
negligence or willful misconduct.

         7.4 Intercreditor Agreement. Lenders and Borrower acknowledge and agree
that the Secured Indebtedness is subordinated in right of payment and priority
to the prior payment in full of the obligations of Borrower to CFC under the
Congress Loan Agreement to the extent set forth in the Intercreditor Agreement
and, to the extent that any terms of the Intercreditor Agreement conflict with
the terms of this Agreement, the terms of the Intercreditor Agreement shall
control.

 8. INDEMNITY AND EXPENSES

         8.1 Indemnification. Borrower shall indemnify, pay and hold each
Lender, and each Lender's officers, directors, partners, employees, affiliates
and agents (collectively, the "Indemnified Persons") harmless from and against
any and all claims, losses, liabilities, costs and expenses of any kind or
nature whatsoever (including reasonable fees and costs of counsel for the
Indemnified Persons) arising out of or resulting from or relating to this
Agreement or the Loan Documents (including, but not limited to, enforcement of
this Agreement) (the foregoing liabilities herein collectively referred to as
the "Indemnified Liabilities"), except claims, losses, liabilities, costs and
expenses resulting from a Lender's gross negligence or willful misconduct. To
the extent that the undertaking to indemnify, pay and hold harmless set forth in
the preceding sentence may be unenforceable because it is violative of any laws
or public policy, Borrower shall contribute the maximum portion that it is
permitted to pay and satisfy under applicable law to the payment and
satisfaction of all Indemnified Liabilities incurred by the Indemnified Persons
or any of them.

         8.2 Expenses. Borrower shall upon demand pay to Lenders the amount of
any and all reasonable expenses, including but not limited to the reasonable
fees and disbursements of its counsel and of any experts and agents, which
Lenders may incur in connection with (i) the custody, preservation, use or
operation of, or the sale of, collection from, or other realization upon, any of
the Collateral, (ii) the exercise or enforcement of any of the rights of Lenders
hereunder or under any Loan Documents, (iii) the failure by Borrower to perform
or observe any of the provisions hereof or (iv) the proposed or actual
amendment, waiver or consent pursuant to the provisions of any of the Loan
Documents resulting from any work-out, renegotiation or restructuring relating
to the performance by Borrower of its obligations under the Loan Documents.
