Trust and Savings Association (the "Bank") and CHANNELL COMMERCIAL CORPORATION
(the "Borrower").


1.  FACILITY NO. 1: LINE OF CREDIT AMOUNT AND TERMS

1.1 LINE OF CREDIT AMOUNT.

(a) During the availability period described below, the Bank will provide a line
    of credit to the Borrower.  The amount of the line of credit (the "Facility
    No. 1 Commitment") is Five Million Dollars ($5,000,000).

(b) This is a revolving line of credit.  During the availability period, the
    Borrower may repay principal amounts and reborrow them.

(c) Each advance must be for at least Fifteen Thousand Dollars ($15,000), or for
    the amount of the remaining available line of credit, if less.

(d) The Borrower agrees not to permit the outstanding principal balance of the
    line of credit to exceed the Facility No. 1 Commitment.

1.2 AVAILABILITY PERIOD.  The line of credit is available between the date of
this Agreement and May 1, 1999 (the "Facility No. 1 Expiration Date") unless the
Borrower is in default.

1.3 INTEREST RATE.

(a) Unless the Borrower elects an optional interest rate as described below, the
    interest rate is the Bank's Reference Rate.

(b) The Reference Rate is the rate of interest publicly announced from time to
    time by the Bank in San Francisco, California, as its Reference Rate.  The
    Reference Rate is set by the Bank based on various factors, including the
    Bank's costs and desired return, general economic conditions and other
    factors, and is used as a reference point for pricing some loans.  The Bank
    may price loans to its customers at, above, or below the Reference Rate.
    Any change in the Reference Rate shall take effect at the opening of
    business on the day specified in the public announcement of a change in the
    Bank's Reference Rate.

1.4 REPAYMENT TERMS.

(a) The Borrower will pay interest on June 1, 1997, and then monthly thereafter
    until payment in full of any principal outstanding under this line of
    credit.

(b) The Borrower will repay in full all principal and any unpaid interest or
    other charges outstanding under this line of credit no later than the
    Facility No. 1 Expiration Date.

(c) Any amount bearing interest at an optional interest rate (as described
    below) may be repaid at the end of the applicable interest period, which
    shall be no later than thirty (30) days after the Facility No. 1 Expiration
    Date.

1.5 OPTIONAL INTEREST RATES.  Instead of the interest rate based on the Bank's
Reference Rate, the Borrower may elect to have all or portions of the line of
credit (during the availability period) bear interest at the rate(s) described
below during an interest period agreed to by the Bank and the Borrower.  Each
interest rate is 

                                      -1-

interest period, the interest rate will revert to the rate based on the
Reference Rate, unless the Borrower has designated another optional interest
rate for the portion.

1.6 FIXED RATE.  The Borrower may elect to have all or portions of the principal
balance of the line of credit bear interest at the Fixed Rate, subject to the
following requirements:

    interest at the Fixed Rate will not be converted to a different rate during
    its interest period.

(f) Each prepayment of a Fixed Rate portion, whether voluntary, by reason of
    acceleration or otherwise, will be accompanied by the amount of accrued
    interest on the amount prepaid, and a prepayment fee equal to the amount (if
    any) by which

    (i)  the additional interest which would have been payable on the amount
         prepaid had it not been paid until the last day of the interest period,
         exceeds

    (ii) the interest which would have been recoverable by the Bank by placing
         the amount prepaid on deposit in the certificate of deposit market for
         a period starting on the date on which it was prepaid and ending on the
         last day of the interest period for such portion.

    interest at the Offshore Rate will not be converted to a different rate
    during its interest period.

(f) Each prepayment of an Offshore Rate portion, whether voluntary, by reason of
    acceleration or otherwise, will be accompanied by the amount of accrued
    interest on the amount prepaid, and a prepayment fee equal to the amount (if
    any) by which

                                      -2-
<PAGE>
 
    (i)  the additional interest which would have been payable on the amount
         prepaid had it not been paid until the last day of the interest period,
         exceeds

    (ii) the interest which would have been recoverable by the Bank by placing
         the amount prepaid on deposit in the offshore dollar market for a

2.  FACILITY NO. 2: LINE OF CREDIT AMOUNT AND TERMS

2.1 Equipment Line.

(a) From time to time during the availability period, the Bank will make
    equipment loans (the "Equipment Loans") to the Borrower as provided herein.
    Each Equipment Loan must be for at least Twenty Five Thousand Dollars
    ($25,000), or for the amount of the remaining available line of credit, if
    less.  The total of all Equipment loans outstanding under the Equipment Line
    (the "Facility No. 2") plus the outstanding amounts of any standby letter of
    credit issued pursuant to Paragraph 2.4, including amounts drawn on letters
    of credit and not yet reimbursed, may not exceed at any one time Five
    Million Dollars ($5,000,000) (the "Facility No. 2 Commitment").

(b) This is a revolving line of credit with a within line facility for standby
    letters of credit and the Borrower may, during the availability period,
    reborrow amounts repaid or prepaid.

(c) The Borrower shall use the proceeds of each Equipment Loan to purchase
    equipment for use in the Borrower's business.  All equipment acquired with
    the proceeds of such advances shall be free and clear of any security
    interests, liens, encumbrances or rights of others.  Each request for an
    Equipment Loan shall be accompanied by a copy of the purchase order or
    invoice for the equipment to be purchased with the proceeds of such
    Equipment Loan.  The amount of each Equipment Loan shall not exceed 80% of
    the purchase price including tax, license and accessories of the equipment
    being purchase.

(d) The Borrower shall repay principal of each Equipment Loan in sixty (60)
    approximately equal monthly installments, commencing on the first day of the
    month following the date the Equipment Loan is made and continuing on the
    first day of each successive month thereafter until the first day of the
    sixtieth month following the month in which the Equipment Loan is made (the
    "Equipment Loan Maturity Date"), on which date all remaining principal and
    interest then owing with respect to the Equipment Loan shall be due and
    payable.

(e) The Borrower may at any time prepay an Equipment Loan in full or in part.
    Partial prepayments shall be applied to the most remote installments of the
    Equipment Loan.

(f) The principal balance of each Equipment Loan shall bear interest at a rate
    per annum equal to the Bank's Reference Rate plus .25 of a percentage point.
    The Borrower will pay interest monthly on the first day of each month until
    the Equipment Loan Maturity Date, on which date all accrued and unpaid
    interest shall be due and payable.

(g) Each Equipment Loan shall be evidenced by a promissory note, in form and
    content acceptable to the Bank.

2.2 OPTIONAL INTEREST RATES.  Instead of the interest rate based on the Bank's
Reference Rate, the Borrower may elect to have all or portions of an Equipment
Loan bear interest at the rate(s) described below 

                                      -3-
<PAGE>
 
during an interest period agreed to by the Bank and the Borrower. Each interest
rate is a rate per year. Interest will be paid on the last day of each interest
period, and on the first day each month during the interest period. At the end
of any interest period, the interest rate will revert to the rate based on the
Reference Rate, unless the Borrower has designated another optional interest
rate for the portion.

2.3 LONG TERM RATE.  The Borrower may elect to have all or portions of an
Equipment Loan bear interest at the Long Term Rate, subject to the following
requirements:

(a) The interest period during which the Long Term Rate will be in effect will
    be one year or more.  The Borrower will immediately begin repaying principal
    of the Long Term Rate portion under an amortization schedule agreed to by
    the Bank and the Borrower at the time of the designation.  These payments
    will be separate from the payments required by the Paragraph 2.1(d) above
    which will be calculated without taking into account any Long Term Rate
    portions.

(b) The "Long Term Rate" means the fixed interest rate the Bank and the Borrower
    agree will apply to the portion during the applicable interest period.

(c) Each Long Term Rate portion will be for an amount not less than One Hundred
    Thousand Dollars ($100,000).

(d) Any Equipment Loan already bearing interest at the Long Term Rate will not
    be converted to a different rate during its interest period.

(e) The Borrower may prepay the Long Term Rate portion in whole or in part in
    the minimum amount of One Hundred Thousand Dollars ($100,000).  The Borrower
    will give the Bank irrevocable written notice of the Borrower's intention to
    make the prepayment, specifying the date and amount of the prepayment.  The
    notice must be received by the Bank at least 5 banking days in advance of
    the prepayment.  All prepayments of principal on the Long Term Rate portion
    will be applied on the most remote principal installment or installments
    then unpaid.

(f) Each prepayment of a Long Term Rate portion, whether voluntary, by reason of
    acceleration or otherwise, will be accompanied by payment of all accrued
    interest on the amount of the prepayment and the prepayment fee described
    below.

(g) The prepayment fee will be the sum of fees calculated separately for each
    Prepaid Installment, as follows:

    (i)  The Bank will first determine the amount of interest which would have
         accrued each month for the Prepaid Installment had it remained
         outstanding until the applicable Original Payment Date, using the Long
         Term Rate;

    (ii) The Bank will then subtract from each monthly interest amount
         determined in (i), above, the amount of interest which would accrue for
         that Prepaid Installment if it were reinvested from the date of
         prepayment through the Original Payment Date, using the following rate:

         (A) If the Original Payment Date is more than 5 years after the date of
             prepayment:  the Treasury Rate plus one-quarter of one percentage
             point;

         (B) If the Original Payment Date is 5 years or less after the date of
             prepayment:  the Money Market Rate.

   (iii) If (i) minus (ii) for the Prepaid Installment is greater than zero,
         the Bank will discount the monthly differences to the date of
         prepayment by the rate used in (ii) above.  The sum of the discounted
         monthly differences is the prepayment fee for that Prepaid Installment.

(h) The following definitions will apply to the calculation of the prepayment
    fee:

                                      -4-
<PAGE>
 
    "Money Market" means the domestic certificate of deposit market, the
    eurodollar deposit market or other appropriate money market selected by the
    Bank.

    "Money Market Rate" means the fixed interest rate per annum which the Bank
    determines could be obtained by reinvesting a specified Prepaid Installment
    in the Money Market from the date of prepayment through the Original Payment
    Date.

    "Original Payment Dates" means the dates on which principal of the Long Term
    Rate portion would have been paid if there had been no prepayment.  If a
    portion of the principal would have been paid later than the end of the
    interest period in effect at the time of prepayment, then the Original
    Payment Date for that portion will be the last day of the interest period.

    "Prepaid Installment" means the amount of the prepaid principal of the Long
    Term Rate portion which would have been paid on a single Original Payment
    Date.

    "Treasury Rate" means the interest rate yield for U.S. Government Treasury
    Securities which the Bank determines could be obtained by reinvesting a
    specified Prepaid Installment in such securities from the date of prepayment
    through the Original Payment Date.

(i) The Bank may adjust the Treasury Rate and Money Market Rate to reflect the
    compounding, accrual basis, or other costs of the Long Term Rate portion.
    Each of the rates is the Bank's estimate only and the Bank is under no
    obligation to actually reinvest any prepayment.  The rates will be based on
    information from either the Telerate or Reuters information services, The
                                                                          ---
    Wall Street Journal, or other information sources the Bank deems 
    -------------------
    appropriate.

2.4 STANDBY LETTERS OF CREDIT UNDER FACILITY NO. 2.

    (i)  Facility No. 2 may be used for financing standby letters of credit with
         a maximum maturity of 12 months but not to extend more than 180 days
         beyond the maturity of May 1, 1999.

    (ii) The amount of outstanding standby letters of credit, including amounts
         drawn on letters of credit and not yet reimbursed, may not exceed at
         any one time Five Hundred Thousand Dollars ($500,000).

The Borrower agrees:

(a) any sum drawn under a letter of credit may, at the option of the Bank, be
    added to the principal amount outstanding under this Agreement.  The amount
    will bear interest and be due as described elsewhere in this Agreement.

(b) if there is a default under this Agreement, to immediately prepay and make
    the Bank whole for any outstanding letters of credit.

(c) the issuance of any letter of credit and any amendment to a letter of credit
    is subject to the Bank's written approval and must be in form and content
    satisfactory to the Bank and in favor of a beneficiary acceptable to the
    Bank.

(d) to sign the Bank's form Application and Agreement for Standby Letter of
    Credit.

(e) to pay any issuance and/or other fees that the Bank notifies the Borrower

    applicable fees, discounts, and other charges.

(g) to pay the Bank a non-refundable fee equal to 1.50% per annum of the
    outstanding undrawn amount of each standby letter of credit, payable
    quarterly in advance, calculated on the basis of the face amount outstanding
    on the day the fee is calculated.

                                      -5-

3.  EXPENSES

The Borrower agrees to reimburse the Bank for any expenses it incurs in the
preparation of this Agreement and any agreement or instrument required by this
Agreement.  Expenses include, but are not limited to, reasonable attorneys'
fees, including any allocated costs of the Bank's in-house counsel.

4.  DISBURSEMENTS, PAYMENTS AND COSTS

4.1 REQUESTS FOR CREDIT.  Each request for an extension of credit will be made
in writing in a manner acceptable to the Bank, or by another means acceptable to
the Bank.

4.2 DISBURSEMENTS AND PAYMENTS.  Each disbursement by the Bank and each payment
by the Borrower will be:

(a) made at the Bank's branch (or other location) selected by the Bank from time
    to time;

(b) made for the account of the Bank's branch selected by the Bank from time to
    time;

(c) made in immediately available funds, or such other type of funds selected by
    the Bank;

(d) evidenced by records kept by the Bank.  In addition, the Bank may, at its
    discretion, require the Borrower to sign one or more promissory notes.

4.3 TELEPHONE AUTHORIZATION.

(a) The Bank may honor telephone instructions for advances or repayments given
    by any one of the individuals authorized to sign loan agreements on behalf
    of the Borrower, or any other individual designated by any one of such
    authorized signers.

(b) Advances will be deposited in and repayments will be withdrawn from the
    Borrower's account number 06004-12147, or such other of the Borrower's
    accounts with the Bank as designated in writing by the Borrower.

(c) The Borrower indemnifies and excuses the Bank (including its officers,
    employees, and agents) from all liability, loss, and costs in connection
    with any act resulting from telephone instructions it reasonably believes
    are made by any individual authorized by the Borrower to give such
    instructions.  This indemnity and excuse will survive this Agreement.

4.4 DIRECT DEBIT (PRE-BILLING).

(a) The Borrower agrees that the Bank will debit the Borrower's deposit account
    number 06004-12147, or such other of the Borrower's accounts with the Bank
    as designated in writing by the Borrower (the "Designated Account") on the
    date each payment of interest becomes due for Facility No. 1 and on the date
    each payment of principal and interest for Facility No. 2 from the Borrower
    becomes due (the "Due Date").  If the Due Date is not a banking day, the
    Designated Account will be debited on the next banking day.

(b) Approximately 10 days prior to each Due Date, the Bank will mail to the
    Borrower a statement of the amounts that will be due on that Due Date (the
    "Billed Amount").  The calculation will be made on the assumption that no
    new extensions of credit or payments will be made between the date of the
    billing statement and the Due Date, and that there will be no changes in the
    applicable interest rate.

(c) The Bank will debit the Designated Account for the Billed Amount, regardless
    of the actual amount due on that date (the "Accrued Amount").

                                      -6-
<PAGE>
 
    If the Billed Amount debited to the Designated Account differs from the
    Accrued Amount, the discrepancy will be treated as follows:

    (i)  If the Billed Amount is less than the Accrued Amount, the Billed Amount
         for the following Due Date will be increased by the amount of the
         discrepancy.  The Borrower will not be in default by reason of any such
         discrepancy.

    (ii) If the Billed Amount is more than the Accrued Amount, the Billed Amount
         for the following Due Date will be decreased by the amount of the
         discrepancy.

    Regardless of any such discrepancy, interest will continue to accrue based
    on the actual amount of principal outstanding without compounding.  The Bank
    will not pay the Borrower interest on any overpayment.

(d) The Borrower will maintain sufficient funds in the Designated Account to
    cover each debit.  If there are insufficient funds in the Designated Account
    on the date the Bank enters any debit authorized by this Agreement, the
    debit will be reversed.

4.5 BANKING DAYS.  Unless otherwise provided in this Agreement, a banking day is
a day other than a Saturday or a Sunday on which the Bank is open for business
in California.  For amounts bearing interest at an offshore rate (if any), a
banking day is a day other than a Saturday or a Sunday on which the Bank is open
for business in California and dealing in offshore dollars.  All payments and
disbursements which would be due on a day which is not a banking day will be due
on the next banking day.  All payments received on a day which is not a banking
day will be applied to the credit on the next banking day.

4.6 TAXES.  The Borrower will not deduct any taxes from any payments it makes to
the Bank.  If any government authority imposes any taxes on any payments made by
the Borrower, the Borrower will pay the taxes and will also pay to the Bank, at
the time interest is paid, any additional amount which the Bank specifies as
necessary to preserve the after-tax yield the Bank would have received if such
taxes had not been imposed.  Upon request by the Bank, the Borrower will confirm
that it has paid the taxes by giving the Bank official tax receipts (or
notarized copies) within 30 days after the due date.  However, the Borrower will
not pay the Bank's net income taxes.

4.7 ADDITIONAL COSTS.  The Borrower will pay the Bank, on demand, for the Bank's
costs or losses arising from any statute or regulation, or any request or
requirement of a regulatory agency which is applicable to all national banks or
a class of all national banks.  The costs and losses will be allocated to the
loan in a manner determined by the Bank, using any reasonable method.  The costs
include the following:

(a) any reserve or deposit requirements; and

(b) any capital requirements relating to the Bank's assets and commitments for
    credit.

4.8 INTEREST CALCULATION.  Except as otherwise stated in this Agreement, all
interest and fees, if any, will be computed on the basis of a 360-day year and
the actual number of days elapsed.  This results in more interest or a higher
fee than if a 365-day year is used.

4.9 INTEREST ON LATE PAYMENTS.  At the Bank's sole option in each instance, any
amount not paid when due under this Agreement (including interest) shall bear
interest from the due date at the Bank's Reference Rate plus 1.25 percentage
points.  This may result in compounding of interest.

4.10  DEFAULT RATE.  Upon the occurrence and during the continuation of any
default under this Agreement, advances under this Agreement will at the option
of the Bank bear interest at a rate per annum which is 1.00 percentage point
higher than the rate of interest otherwise provided under this Agreement.  This
will not constitute a waiver of any default.

                                      -7-

10.4  ARBITRATION.

(a) This paragraph concerns the resolution of any controversies or claims
    between the Borrower and the Bank, including but not limited to those that
    arise from:

    (i)   This Agreement (including any renewals, extensions or modifications of
          this Agreement);

    (ii)  Any document, agreement or procedure related to or delivered in
          connection with this Agreement;

    (iii) Any violation of this Agreement; or

    (iv)  Any claims for damages resulting from any business conducted between
          the Borrower and the Bank, including claims for injury to persons,
          property or business interests (torts).

(b) At the request of the Borrower or the Bank, any such controversies or claims
    will be settled by arbitration in accordance with the United States
    Arbitration Act.  The United States Arbitration Act will apply even though
    this Agreement provides that it is governed by California law.

(c) Arbitration proceedings will be administered by the American Arbitration
    Association and will be subject to its commercial rules of arbitration.

(d) For purposes of the application of the statute of limitations, the filing of
    an arbitration pursuant to this paragraph is the equivalent of the filing of
    a lawsuit, and any claim or controversy which may be arbitrated under this
    paragraph is subject to any applicable statute of limitations.  The
    arbitrators will have the authority to decide whether any such claim or
    controversy is barred by the statute of limitations and, if so, to dismiss
    the arbitration on that basis.

(e) If there is a dispute as to whether an issue is arbitrable, the arbitrators
    will have the authority to resolve any such dispute.

(f) The decision that results from an arbitration proceeding may be submitted to
    any authorized court of law to be confirmed and enforced.

(g) The procedure described above will not apply if the controversy or claim, at
    the time of the proposed submission to arbitration, arises from or relates
    to an obligation to the Bank secured by real property located in California.
    In this case, both the Borrower and the Bank must consent to submission of
    the claim or controversy to arbitration.  If both parties do not consent to
    arbitration, the controversy or claim will be settled as follows:

    (i)   The Borrower and the Bank will designate a referee (or a panel of
          referees) selected under the auspices of the American Arbitration
          Association in the same manner as arbitrators are selected in
          Association-sponsored proceedings;

    (ii)  The designated referee (or the panel of referees) will be appointed by
          a court as provided in California Code of Civil Procedure Section 638
          and the following related sections;

    (iii) The referee (or the presiding referee of the panel) will be an active
          attorney or a retired judge; and

                                      -13-
<PAGE>
 
    (iv)  The award that results from the decision of the referee (or the panel)
          will be entered as a judgment in the court that appointed the referee,
          in accordance with the provisions of California Code of Civil
          Procedure Sections 644 and 645.

(h) This provision does not limit the right of the Borrower or the Bank to:

    (i)   exercise self-help remedies such as setoff;

    (ii)  foreclose against or sell any real or personal property collateral; or

    (iii) act in a court of law, before, during or after the arbitration
          proceeding to obtain:

         (A)  an interim remedy; and/or

         (B) additional or supplementary remedies.

(i) The pursuit of or a successful action for interim, additional or
    supplementary remedies, or the filing of a court action, does not constitute
    a waiver of the right of the Borrower or the Bank, including the suing
    party, to submit the controversy or claim to arbitration if the other party
    contests the lawsuit.  However, if the controversy or claim arises from or
    relates to an obligation to the Bank which is secured by real property
    located in California at the time of the proposed submission to arbitration,
    this right is limited according to the provision above requiring the consent
    of both the Borrower and the Bank to seek resolution through arbitration.

(j) If the Bank forecloses against any real property securing this Agreement,
    the Bank has the option to exercise the power of sale under the deed of
    trust or mortgage, or to proceed by judicial foreclosure.

10.5  SEVERABILITY; WAIVERS.  If any part of this Agreement is not enforceable,
the rest of the Agreement may be enforced.  The Bank retains all rights, even if
it makes a loan after default.  If the Bank waives a default, it may enforce a

costs incurred by the Bank in connection with administering this Agreement.

any amendment, waiver, "workout" or restructuring under this Agreement.  In the
event of a lawsuit or arbitration proceeding, the prevailing party is entitled
to recover costs and reasonable attorneys' fees incurred in connection with the
lawsuit or arbitration proceeding, as determined by the court or arbitrator.  As
used in this paragraph, "attorneys' fees" includes the allocated costs of in-
house counsel.

10.8  ONE AGREEMENT.  This Agreement and any related security or other
agreements required by this Agreement, collectively:

(a) represent the sum of the understandings and agreements between the Bank and
    the Borrower concerning this credit; and
