                                                               September 1, 1999

     FOR VALUE RECEIVED, the undersigned The Keith Companies, Inc., John M.
Tettemer & Associates, Ltd., and ESI, Engineering Services, Inc. ("Borrower")
promises to pay to the order of Wells Fargo Bank, National Association ("Bank")
at its Orange Coast Regional Commercial Banking Office at 2030 Main Street,
Suite 900, Irvine, California 90071, or at such other place as the holder hereof
may designate, in lawful money of the United States of America and in
immediately available funds, the principal sum of Eight Million Five Hundred
Thousand Dollars ($8,500,000.00), or so much thereof as may be advanced and be
outstanding, with interest thereon, to be computed on each advance from the date
of its disbursement as set forth herein.

DEFINITIONS:

     As used herein, the following terms shall have the meanings set forth after
each, and any other term defined in this Note shall have the meaning set forth
at the place defined:

     (a)  "Business Day" means any day except a Saturday, Sunday or any other
day on which commercial banks in California are authorized or required by law to
close.

     (b)  "Fixed Rate Term" means a period commencing on a Business Day and
continuing for 1, 2, 3, or 6 months, as designated by Borrower, during which all
or a portion of the outstanding principal balance of this Note bears interest
determined in relation to LIBOR; provided however, that no Fixed Rate Term may
be selected for a principal amount less than $100,000.00 with respect to Working
Capital Advances or $100,000.00 with respect to Equipment Advances; and provided
further, that no Fixed Rate Term shall extend beyond the scheduled maturity date
hereof. If any Fixed Rate Term would end on a day which is not a Business Day,
then such Fixed Rate Term shall be extended to the next succeeding Business Day.

     (c)  "LIBOR" means the rate per annum (rounded upward, if necessary, to the
nearest whole 1/8 of 1%) and determined pursuant to the following formula:

     LIBOR =             Base LIBOR
               -------------------------------
               100% - LIBOR Reserve Percentage

     (i)  "Base LIBOR" means the rate per annum for United States dollar
deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the
understanding that such rate is quoted by Bank for

                                       1


the purpose of calculating effective rates of interest for loans making
reference thereto, on the first day of a Fixed Rate Term for delivery of funds
on said date for a period of time approximately equal to the number of days in
such Fixed Rate Term and in an amount approximately equal to the principal
amount to which such Fixed Rate Term applies. Borrower understands and agrees
that Bank may base its quotation of the Inter-Bank Market Offered Rate upon such
offers or other market indicators of the Inter-Bank Market as Bank in its
discretion deems appropriate including, but not limited to, the rate offered for
U.S. dollar deposits on the London Inter-Bank Market.

    (ii)  "LIBOR Reserve Percentage" means the reserve percentage prescribed by
the Board of Governors of the Federal Reserve System (or any successor) for
"Eurocurrency Liabilities" (as defined in Regulation D of the Federal Reserve
Board, as amended), adjusted by Bank for expected changes in such reserve
percentage during the applicable Fixed Rate Term.

     (d)  "Prime Rate" means at any time the rate of interest most recently
announced within Bank at its principal office as its Prime Rate, with the
understanding that the Prime Rate is one of Bank's base rates and serves as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

     (a)  Interest.  The outstanding principal balance of this Note shall bear
          --------
interest (computed on the basis of a 360-day year, actual days elapsed) either
(i) at a fluctuating rate per annum equal to the Prime Rate in effect from time
to time, or (ii) with respect to Working Capital Advances, at a fixed rate per
annum determined by Bank to be one and three-quarters percent (1.75%) above
LIBOR in effect on the first day of the applicable Fixed Rate Term, and (iii)
with respect to Equipment Advances, at a fixed rate per annum determined by Bank
to be two percent (2.00%) above LIBOR in effect on the first day of the
applicable Fixed Rate Term.  When interest is determined in relation to the
Prime Rate, each change in the rate of interest hereunder shall become effective
on the date each Prime Rate change is announced within Bank.  With respect to
each LIBOR selection hereunder, Bank is hereby authorized to note the date,
principal amount, interest rate and Fixed Rate Term applicable thereto and any
payments made thereon on Bank's books and records (either manually or by
electronic entry) and/or on any schedule attached to this Note, which notations
shall be prima facie evidence of the accuracy of the information noted.

     (b)  Selection of Interest Rate Options.  At any time any portion of this
          ----------------------------------
Note bears interest determined in relation to

                                       2


LIBOR, it may be continued by Borrower at the end of the Fixed Rate Term
applicable thereto so that all or a portion thereof bears interest determined in
relation to the Prime Rate or to LIBOR for a new Fixed Rate Term designated by
Borrower. At any time any portion of this Note bears interest determined in
relation to the Prime Rate, Borrower may convert all or a portion thereof so
that it bears interest determined in relation to LIBOR for a Fixed Rate Term
designated by Borrower. At such time as Borrower requests an advance hereunder
or wishes to select a LIBOR option for all or a portion of the outstanding
principal balance hereof, and at the end of each Fixed Rate Term, Borrower shall
give Bank notice specifying: (i) the interest rate option selected by Borrower;
(ii) the principal amount subject thereto; and (iii) for each LIBOR selection,
the length of the applicable Fixed Rate Term. Any such notice may be given by
telephone so long as, with respect to each LIBOR selection, (A) Bank receives
written confirmation from Borrower not later than three (3) Business Days after
such telephone notice is given, and (B) such notice is given to Bank prior to
10:00 a.m., California time, on the first day of the Fixed Rate Term. For each
LIBOR option requested hereunder, Bank will quote the applicable fixed rate to
Borrower at approximately 10:00 a.m., California time, on the first day of the
Fixed Rate Term. If Borrower does not immediately accept the rate quoted by
Bank, any subsequent acceptance by Borrower shall be subject to a
redetermination by Bank of the applicable fixed rate; provided however, that if
Borrower fails to accept any such rate by 11:00 a.m., California time, on the
Business Day such quotation is given, then the quoted rate shall expire and Bank
shall have no obligation to permit a LIBOR option to be selected on such day. If
no specific designation of interest is made at the time any advance is requested
hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to have
made a Prime Rate interest selection for such advance or the principal amount to
which such Fixed Rate Term applied.

     (c)  Additional LIBOR Provisions.
          ---------------------------

     (i)  If Bank at any time shall determine that for any reason adequate and
reasonable means do not exist for ascertaining LIBOR, then Bank shall promptly
give notice thereof to Borrower.  If such notice is given and until such notice
has been withdrawn by Bank, then (A) no new LIBOR option may be selected by
Borrower, and (B) any portion of the outstanding principal balance hereof which
bears interest determined in relation to LIBOR, subsequent to the end of the
Fixed Rate Term applicable thereto, shall bear interest determined in relation
to the Prime Rate.

    (ii)  If any law, treaty, rule, regulation or determination of a court or
governmental authority or any change therein or in the interpretation or
application thereof (each, a "Change in Law") shall make it unlawful for Bank
(A) to make LIBOR options

                                       3


available hereunder, or (B) to maintain interest rates based on LIBOR, then in
the former event, any obligation of Bank to make available such unlawful LIBOR
options shall immediately be cancelled, and in the latter event, any such
unlawful LIBOR-based interest rates then outstanding shall be converted, at
Bank's option, so that interest on the portion of the outstanding principal
balance subject thereto is determined in relation to the Prime Rate; provided
however, that if any such Change in Law shall permit any LIBOR-based interest
rates to remain in effect until the expiration of the Fixed Rate Term applicable
thereto, then such permitted LIBOR-based interest rates shall continue in effect
until the expiration of such Fixed Rate Term. Upon the occurrence of any of the
foregoing events, Borrower shall pay to Bank immediately upon demand such
amounts as may be necessary to compensate Bank for any fines, fees, charges,
penalties or other costs incurred or payable by Bank as a result thereof and
which are attributable to any LIBOR options made available to Borrower
hereunder, and any reasonable allocation made by Bank among its operations shall
be conclusive and binding upon Borrower.

   (iii)  If any Change in Law or compliance by Bank with any request or
directive (whether or not having the force of law) from any central bank or
other governmental authority shall:

     (A)  subject Bank to any tax, duty or other charge with respect to any
          LIBOR options, or change the basis of taxation of payments to Bank of
          principal, interest, fees or any other amount payable hereunder
          (except for changes in the rate of tax on the overall net income of
          Bank); or

     (B)  impose, modify or hold applicable any reserve, special deposit,
          compulsory loan or similar requirement against assets held by,
          deposits or other liabilities in or for the account of, advances or
          loans by, or any other acquisition of funds by any office of Bank; or

     (C)  impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining any LIBOR options hereunder and/or to reduce any
amount receivable by Bank in connection therewith, then in any such case,
Borrower shall pay to Bank immediately upon demand such amounts as may be
necessary to compensate Bank for any additional costs incurred by Bank and/or
reductions in amounts received by Bank which are attributable to such LIBOR
options. In determining which costs incurred by Bank and/or reductions in
amounts received by Bank are attributable to any LIBOR options made available to
Borrower hereunder, any reasonable allocation made by Bank among its operations
shall be conclusive and binding upon Borrower.

                                       4


     (d)  Payment of Interest.  Interest accrued on this Note shall be payable
          -------------------
on the third day of each month, commencing October 3, 1999.

     (e)  Default Interest.  From and after the maturity date of this Note, or
          ----------------
such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to two percent (2%) above
the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

     (a)  Borrowing and Repayment.  Borrower may from time to time during the
          -----------------------
term of this Note borrow, partially or wholly repay its outstanding borrowings,
and reborrow Working Capital Advances, subject to all of the limitations, terms
and conditions of this Note and of any document executed in connection with or
governing this Note; provided however, that the total outstanding borrowings
under this Note shall not at any time exceed the principal amount stated above.
The unpaid principal balance of this obligation at any time shall be the total
amounts advanced hereunder by the holder hereof less the amount of principal
payments made hereon by or for any Borrower, which balance may be endorsed
hereon from time to time by the holder. The outstanding principal balance of
Equipment Advances on September 3, 2000 shall be due and payable on the third
day of each month in 60 equal consecutive installments, each equal to 1/60th of
such outstanding principal balance, commencing on October 3, 2000 to and
including September 3, 2005. The outstanding principal balance of Working
Capital Advances shall be due and payable in full on September 3, 2001.

     (b)  Advances.  Working Capital Advances, to the total amount of the
          --------
principal sum set forth in the Credit Agreement (defined below), may be made by
the holder at the oral or written request of (i) Aram Keith, CEO or Gary
                                                 ---------------    ----
Campanaro, CFO, any one acting alone, who are authorized to request advances and
- --------------
direct the disposition of any advances until written notice of the revocation of
such authority is received by the holder at the office designated above, or (ii)
any person, with respect to advances deposited to the credit of any account of
any Borrower with the holder, which advances, when so deposited, shall be
conclusively presumed to have been made to or for the benefit of each Borrower
regardless of the fact that persons other than those authorized to request
advances may have authority to draw against such account.  The holder shall have
no obligation to determine whether any person requesting an advance is or has
been authorized by any Borrower. Equipment Advances shall be available in the
manner set forth in the Credit Agreement.

                                       5


     (c)  Application of Payments.  Each payment made on this Note shall be
          -----------------------
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied to
Working Capital Advances and/or Equipment Advances as described in the Credit
Agreement, and shall be so applied first, to the outstanding principal balance
of applicable advances which bears interest determined in relation to the Prime
Rate, if any, and second, to the outstanding principal balance of the advances
which bears interest determined in relation to LIBOR, with such payments applied
to the oldest Fixed Rate Term first.

PREPAYMENT:

     (a)  Prime Rate.  Borrower may prepay principal on any portion of this Note
          ----------
which bears interest determined in relation to the Prime Rate at any time, in
any amount and without penalty.

     (b)  LIBOR.  Borrower may prepay principal on any portion of this Note
          -----
which bears interest determined in relation to LIBOR at any time and in the
minimum amount of $500,000.00; provided however, that if the outstanding
principal balance of such portion of this Note is less than said amount, the
minimum prepayment amount shall be the entire outstanding principal balance
thereof. In consideration of Bank providing this prepayment option to Borrower,
or if any such portion of this Note shall become due and payable at any time
prior to the last day of the Fixed Rate Term applicable thereto by acceleration
or otherwise, Borrower shall pay to Bank immediately upon demand a fee which is
the sum of the discounted monthly differences for each month from the month of
prepayment through the month in which such Fixed Rate Term matures, calculated
as follows for each such month:

     (i)  Determine the amount of interest which would have accrued each month
          ---------
          on the amount prepaid at the interest rate applicable to such amount
          had it remained outstanding until the last day of the Fixed Rate Term
          applicable thereto.

    (ii)  Subtract from the amount determined in (i) above the amount of
          --------
          interest which would have accrued for the same month on the amount
          prepaid for the remaining term of such Fixed Rate Term at LIBOR in
          effect on the date of prepayment for new loans made for such term and
          in a principal amount equal to the amount prepaid.

   (iii)  If the result obtained in (ii) for any month is greater than zero,
          discount that difference by LIBOR used in (ii) above.

Each Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or

                                       6


liabilities, and that it is difficult to ascertain the full extent of such
costs, expenses and/or liabilities. Each Borrower, therefore, agrees to pay the
above-described prepayment fee and agrees that said amount represents a
reasonable estimate of the prepayment costs, expenses and/or liabilities of
Bank. If Borrower fails to pay any prepayment fee when due, the amount of such
prepayment fee shall thereafter bear interest until paid at a rate per annum
2.00% above the Prime Rate in effect from time to time (computed on the basis of
a 360-day year, actual days elapsed). Each change in the rate of interest on any
such past due prepayment fee shall become effective on the date each Prime Rate
change is announced within Bank. Prepayments of principal applied to Equipment
Advances after September 3, 2000 shall be applied to the scheduled installments
in inverse order of maturity.

EVENTS OF DEFAULT:

     This Note is made pursuant to and is subject to the terms and conditions of
that certain Credit Agreement between Borrower and Bank dated as of September 1,
1999, as amended from time to time (the "Credit Agreement").  Any default in the
payment or performance of any obligation under this Note, or any defined event
of default under the Credit Agreement, shall constitute an "Event of Default"
under this Note.

MISCELLANEOUS:

     (a)  Remedies.  Upon the occurrence of any Event of Default, the holder of
          --------
this Note, at the holder's option, may declare all sums of principal and
interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor, all of which are expressly waived by each Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Each Borrower shall pay to the holder
immediately upon demand the full amount of all payments, advances, charges,
costs and expenses, including reasonable attorneys' fees (to include outside
counsel fees and all allocated costs of the holder's in-house counsel), expended
or incurred by the holder in connection with the enforcement of the holder's
rights and/or the collection of any amounts which become due to the holder under
this Note, and the prosecution or defense of any action in any way related to
this Note, including without limitation, any action for declaratory relief,
whether incurred at the trial or appellate level, in an arbitration proceeding
or otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any
Borrower or any other person or entity.

                                       7


     (b)  Obligations Joint and Several.  Should more than one person or entity
          -----------------------------

joint and several.

     (c)  Governing Law.  This Note shall be governed by and construed in
          -------------
accordance with the laws of the State of California.

     IN WITNESS WHEREOF, the undersigned has executed this Note as of the date
first written above.
