U.S. BANK NATIONAL ASSOCIATION                                       ("Lender")

1. TYPE OF CREDIT. This note is given to evidence Borrower's obligation to repay
all sums which Lender may from time to time advance to Borrower ("Advances")
under a:

      |_|   single disbursement loan. Amounts loaned to Borrower hereunder will
            be disbursed in a single Advance in the amount shown in Section 2.

      |X|   revolving line of credit. No Advances shall be made which create a
            maximum amount outstanding at any one time which exceeds the maximum
            amount shown in Section 2. However, Advances hereunder may be
            borrowed, repaid and reborrowed, and the aggregate Advances loaned
            hereunder from time to time may exceed such maximum amount.

      |_|   non-revolving line of credit. Each Advance made from time to time
            hereunder shall reduce the maximum amount available shown in Section
            2. Advances loaned hereunder which are repaid may not be reborrowed.

2. PRINCIPAL BALANCE. The unpaid principal balance of all Advances outstanding
under this note ("Principal Balance") at one time shall not exceed
$20,000,000.00.

3. PROMISE TO PAY. For value received Borrower promises to pay to Lender or
order at Commercial Loan Service Center - West, 555 SW Oak, Portland, OR 97204,
the Principal Balance of this note, with interest thereon at the rate(s)
specified in Sections 4 and 11 below.

4. INTEREST RATE. The interest rate on the Principal Balance outstanding may
vary from time to time pursuant to the provisions of this note. Subject to the
provisions of this note, Borrower shall have the option from time to time of
choosing to pay interest at the rate or rates and for the applicable periods of
time based on the rate options provided herein; provided, however, that once
Borrower notifies Lender of the rate option chosen in accordance with the
provisions of this note, such notice shall be irrevocable. The rate options are
the Prime Borrowing Rate and the LIBOR Borrowing Rate, each as defined herein.

(a) Definitions. The following terms shall have the following meanings:

      "Business Day" means any day other than a Saturday, Sunday, or other day
that commercial banks in Portland, Oregon, Minneapolis, Minnesota, or New York
City are authorized or required by law to close; provided, however that when
used in connection with a LIBOR Rate, LIBOR Amount or LIBOR Interest Period such
term shall also exclude any day on which dealings in U.S. dollar deposits are
not carried on in the London interbank market.

      "Dow Jones Page 3750" means the display designated as such on the Dow
Jones Markets Service (formerly known as Telerate) (or such other page as may
replace page 3750 on that service for the purpose of displaying London interbank
offered rates of major banks for United States Dollar deposits).

      "LIBOR Amount" means each principal amount for which Borrower chooses to
have the LIBOR Borrowing Rate apply for any specified LIBOR Interest Period.

      "LIBOR Interest Period" means as to any LIBOR Amount, a period of One,
Two, or Three months commencing on the date the LIBOR Borrowing Rate becomes
applicable thereto; provided, however, that: (i) the first day of each LIBOR
Interest Period must be a Business Day; (ii) no LIBOR Interest Period shall
commence on or after August 31, 2001; (iii) no LIBOR Interest Period shall be
selected which would extend beyond September 30, 2001; (iv) no LIBOR Interest
Period shall extend beyond the date of any principal payment required under
Section 6 of this note, unless the sum of the Prime Rate Amount, plus LIBOR
Amounts with LIBOR Interest Periods ending on or before the scheduled date of
such principal payment, plus principal amounts remaining unborrowed under a line
of credit, equals or exceeds the amount of such principal payment; (v) any LIBOR
Interest Period which would otherwise expire on a day which is not a Business
Day, shall be extended to the next succeeding Business Day, unless the result of
such extension would be to extend such LIBOR Interest Period into another
calendar month, in which event the LIBOR Interest Period shall end on the
immediately preceding Business Day; and (vi) any LIBOR Interest Period that
begins on the last Business Day of a calendar month (or on a day for which there
is no numerically corresponding day in the calendar month at the end of such
LIBOR Interest Period) shall end on the last Business Day of a calendar month.

      "LIBOR Rate" means, for any LIBOR Interest Period, the average offered
rate for deposits in United States Dollars (rounded upwards, if necessary, to
the nearest 1/16 of 1%) for delivery of such deposits on the first day of such
LIBOR Interest Period, for the number of months therein, which appears on Dow
Jones Page 3750 as of 11:00 a.m., London time (or such other time as of which
such rate appears) on the day that is two Business Days preceding the first day
of such LIBOR Interest Period; or the rate for such deposits determined by
Lender at such time based on such other published service of general application
as shall be selected by Lender for such purpose; provided, that in lieu of
determining the rate in the foregoing manner, Lender may determine the rate
based on the rates offered to Lender for deposits in United States Dollars
(rounded upwards, if necessary, to the nearest 1/16 of 1%) in the interbank
eurodollar market at such time for delivery on the first day of such LIBOR
Interest Period for the number of months therein; and provided, further, that in
any case the LIBOR Rate shall be adjusted to take into account the maximum
reserves required to be maintained for Eurocurrency liabilities by banks during
each such LIBOR Interest Period as specified in Regulation D of the Board of
Governors of the Federal Reserve System or any successor regulation.

      "Prime Rate" means the rate of interest which Lender from time to time
establishes as its prime or reference rate and is not, for example, the lowest
rate of interest which Lender collects from any borrower or class of borrowers.
When the Prime Rate is applicable under Section 4(b) or 11(b), the interest rate
hereunder shall be adjusted without notice effective on the day the Prime Rate
changes, but in no event shall the rate of interest be higher than allowed by
law.

      "Prime Rate Amount" means any portion of the Principal Balance bearing
interest at the Prime Borrowing Rate.

(b) The Prime Borrowing Rate.

      (i) The Prime Borrowing Rate is a variable per annum rate equal to the
Prime Rate plus 0%.

      (ii) Whenever Borrower desires to use the Prime Borrowing Rate option,
Borrower shall give Lender notice orally or in writing in accordance with
Section 15 of this note, which notice shall specify the requested effective date
(which must be a Business Day) and principal amount of the Advance or increase
in the Prime Rate Amount, and whether Borrower is requesting a new Advance under
a line of credit or conversion of a LIBOR Amount to the Prime Borrowing Rate.

      (iii) Subject to Section 11 of this note, interest shall accrue on the
unpaid Principal Balance at the Prime Borrowing Rate unless and except to the
extent that the LIBOR Borrowing Rate is in effect.

(c) The LIBOR Borrowing Rate.

      (i) The LIBOR Borrowing Rate is the LIBOR Rate plus See Attached Exhibit
"A" for LIBOR Pricing Matrix per annum.

      (ii) Borrower may obtain LIBOR Borrowing Rate quotes from Lender before
10:00 a.m. (Portland, Oregon time) on any Business Day. Borrower may request an
Advance, conversion of any portion of the Prime Rate Amount to a LIBOR Amount or
a new LIBOR Interest Period for an existing LIBOR Amount, at such rate only by
giving Lender notice in accordance with Section 4(c)(iii) before 10:00 a.m.
(Portland, Oregon time) on such day.

      (iii) Whenever Borrower desires to use the LIBOR Borrowing Rate option,
Borrower shall give Lender irrevocable notice (either in writing or orally and
promptly confirmed in writing) no later than 10:00 a.m. (Portland, Oregon time)
two (2) Business Days prior to the desired effective date of such rate. Any oral
notice shall be given by, and any written notice or confirmation of an oral
notice shall be signed by, the person(s) authorized in Section 15 of this note,
and shall specify the requested effective date of the rate, LIBOR Interest
Period and LIBOR Amount, and whether Borrower is requesting a new Advance at the
LIBOR Borrowing Rate

<PAGE>

under a line of credit, conversion of all or any portion of the Prime Rate
Amount to a LIBOR Amount, or a new LIBOR Interest Period for an outstanding
LIBOR Amount. Notwithstanding any other term of this note, Borrower may elect
the LIBOR Borrowing Rate in the minimum principal amount of $500,000.00 and in
multiples of $100,000.00 above such amount; provided, however, that no more than
N/A separate LIBOR Interest Period may be in effect at any one time.

      (iv) If at any time the LIBOR Rate is unascertainable or unavailable to
Lender or if LIBOR Rate loans become unlawful, the option to select the LIBOR
Borrowing Rate shall terminate immediately. If the LIBOR Borrowing Rate is then
in effect, (A) it shall terminate automatically with respect to all LIBOR
Amounts (i) on the last day of each then applicable LIBOR Interest Period, if
Lender may lawfully continue to maintain such loans, or (ii) immediately if
Lender may not lawfully continue to maintain such loans through such day, and
(B) subject to Section 11, the Prime Borrowing Rate automatically shall become
effective as to such amounts upon such termination.

      (v) If at any time after the date hereof (A) any revision in or adoption
of any applicable law, rule, or regulation or in the interpretation or
administration thereof (i) shall subject Lender or its Eurodollar lending office
to any tax, duty, or other charge, or change the basis of taxation of payments
to Lender with respect to any loans bearing interest based on the LIBOR Rate, or
(ii) shall impose or modify any reserve, insurance, special deposit, or similar
requirements against assets of, deposits with or for the account of, or credit
extended by Lender or its Eurodollar lending office, or impose on Lender or its
Eurodollar lending office any other condition affecting any such loans, and (B)
the result of any of the foregoing is (i) to increase the cost to Lender of
making or maintaining any such loans or (ii) to reduce the amount of any sum
receivable under this note by Lender or its Eurodollar lending office, Borrower
shall pay Lender within 15 days after demand by Lender such additional amount as
will compensate Lender for such increased cost or reduction. The determination
hereunder by Lender of such additional amount shall be conducive in the absence
of manifest error. If Lender demands compensation under this Section 4(c)(v),
Borrower may upon three (3) Business Days' notice to Lender pay the accrued
interest on all LIBOR Amounts, together with any additional amounts payable
under Section 4(c)(vi). Subject to Section 11, upon Borrower's paying such
accrued interest and additional costs, the Prime Borrowing Rate immediately
shall be effective with respect to the unpaid principal balance of such LIBOR
Amounts.

      (vi) Borrower will indemnify Lender upon demand against any loss or
expense which Lender may sustain or incur (including, without limitation, any
loss or expense sustained or incurred in obtaining, liquidating or employing
deposits or other funds acquired to effect, fund or maintain any portion of the
loan or any Advance) as a consequence of (A) any failure of Borrower to make any
payment when due of any amount due hereunder, (B) any failure of Borrower to
borrow, if permitted by the terms of this note, continue or convert any portion
of the Prime Rate Amount to a LIBOR Amount, on a date specified therefor in a
notice thereof, or (C) any payment, voluntary or mandatory prepayment or payment
on default or conversion of any LIBOR Amount to the Prime Borrowing Rate, on a
date other than the last day of the applicable LIBOR Interest Period.
Determinations by Lender of the amount required to indemnify Lender shall be
conclusive in the absence of manifest error.

      (vii) Notwithstanding any provision of this note to the contrary, Lender
shall be entitled to fund and maintain its funding of all or any part of the
loan evidenced by this note in any manner it elects; it being understood,
however, that with respect to any LIBOR Amount, all determinations hereunder
shall be made as if Lender had actually funded and maintained each LIBOR Amount
during the LIBOR Interest Period applicable to it through the purchase of
deposits having a term corresponding to such LIBOR Interest Period and bearing
an interest rate equal to the LIBOR Rate for such LIBOR Interest Period (whether
or not Lender shall have granted any participations in such LIBOR Amounts).

      (viii) Notwithstanding any other term of this note, Borrower may not
select the LIBOR Borrowing Rate if an event of default hereunder has occurred
and is continuing.

      (ix) Nothing contained in this note, including without limitation the
determination of any LIBOR Interest Period or Lender's quotation of any LIBOR
Borrowing Rate, shall be construed to prejudice Lender's right, if any, to
decline to make any requested Advance or to require payment on demand.

5. COMPUTATION OF INTEREST. All interest under Section 4 and Section 11 will be
computed at the applicable rate based on a 360-day year and applied to the
actual number of days elapsed.

            |_|   ________________________________________________.

7. PREPAYMENT.

(a)   Prepayments of all or any part of the Prime Rate Amount may be made at any
      time without penalty.

(b)   Except as otherwise specifically set forth herein, Borrower may not prepay
      all or any part of any LIBOR Amount or terminate any LIBOR Borrowing Rate,
      except on the last day of the applicable LIBOR Interest Period.

(c)   Principal prepayments will not postpone the date of or change the amount
      of any regularly scheduled payment. At the time of any principal
      prepayment, all accrued interest, fees, costs and expenses shall also be
      paid.

8. CHANGE IN PAYMENT AMOUNT. Each time the interest rate on this note changes
the holder of this note may, from time to time, in holder's sole discretion,
increase or decrease the amount of each of the installments remaining unpaid at
the time of such change in rate to an amount holder in its sole discretion deems
necessary to continue amortizing the Principal Balance at the same rate
established by the installment amounts specified in Section 6(a), whether or not
a "balloon" payment may also be due upon maturity of this note. Holder shall
notify the undersigned of each such change in writing. Whether or not the
installment amount is increased under this Section 8, Borrower understands that,
as a result of increases in the rate of interest the final payment due, whether
or not a "balloon" payment, shall include the entire Principal Balance and
interest thereon then outstanding, and may be substantially more than the
installment specified in Section 6.

9. ALTERNATE PAYMENT DATE. Notwithstanding any other term of this note, if in
any month there is no day on which a scheduled payment would otherwise be due
(e.g. February 31), such payment shall be paid on the last banking day of that
month.

10. PAYMENT BY AUTOMATIC DEBIT.
<PAGE>

|X| Borrower hereby authorizes Lender to automatically deduct the amount of all
principal and interest payments from account number 153600038365 with Lender. If
there are insufficient funds in the account to pay the automatic deduction in
full, Lender may allow the account to become overdrawn, or Lender may reverse
the automatic deduction. Borrower will pay all the fees on the account which
result from the automatic deductions, including any overdraft and non-sufficient
funds charges. If for any reason Lender does not charge the account for a
payment, or if an automatic payment is reversed, the payment is still due
according to this note. If the account is a Money Market Account, the number of
withdrawals from that account is limited as set out in the account agreement.
Lender may cancel the automatic deduction at any time in its discretion.

Provided, however, if no account number is entered above, Borrower does not want
to make payments by automatic debit.

11. DEFAULT.

(a) Without prejudice to any right of Lender to require payment on demand or to
decline to make any requested Advance, each of the following shall be an event
of default: (i) Borrower fails to make any payment when due. (ii) Borrower fails
to perform or comply with any term, covenant or obligation in this note or any
agreement related to this note, or in any other agreement or loan Borrower has
with Lender or any affiliate of Lender. (iii) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this note or
perform Borrower's obligations under this note or any related documents. (iv)
Any representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished. (v) Borrower dies, becomes insolvent, liquidates
or dissolves, a receiver is appointed for any part of Borrower's property.
Borrower makes an assignment for the benefit of creditors, or any proceeding is
commenced either by Borrower or against Borrower under any bankruptcy or
insolvency laws. (vi) Any creditor tries to take any of Borrower's property on
or in which Lender has a lien or security interest. This includes a garnishment
of any of Borrower's accounts with Lender. (vii) Any of the events described in
this default section occurs with respect to any general partner in Borrower or
any guarantor of this note, or any guaranty of Borrower's indebtedness to Lender
ceases to be, or is asserted not to be, in full force and effect. (viii) There
is any material adverse change in the financial condition or management of
Borrower or Lender in good faith deems itself insecure with respect to the
payment or performance of Borrower's obligations to Lender. If the note is
payable on demand, the inclusion of specific events of default shall not
prejudice Lender's right to require payment on demand or to decline to make any
requested Advance.

(b) Without prejudice to any right of Lender to require payment on demand, upon
the occurrence of an event of default, Lender may declare the entire unpaid
Principal Balance on this note and all accrued unpaid interest immediately due
and payable, without notice; provided, however, that if any proceeding under any
bankruptcy or insolvency law is commenced by or against Borrower, the
availability of Advances shall be immediately terminated without notice and the
entire Principal Balance and all accrued interest shall, without notice, become
immediately due and payable. Upon default, including failure to pay upon final
maturity, Lender, at its option, may also, if permitted under applicable law,
increase the interest rate on this note to a rate equal to the Prime Borrowing
Rate plus 6%. The interest rate will not exceed the maximum rate permitted by
applicable law. In addition, if any payment of principal or interest is 19 or
more days past due, Borrower will be charged a late charge of 5% of the
delinquent payment.

12. EVIDENCE OF PRINCIPAL BALANCE; PAYMENT ON DEMAND. Holder's records shall, at
any time, be conclusive evidence of the unpaid Principal Balance and interest
owing on this note. Notwithstanding any other provisions of this note, in the
event holder makes Advances hereunder which result in an unpaid Principal
Balance on this note which at any time exceeds the maximum amount specified in
Section 2, Borrower agrees that all such Advances, with interest, shall be
payable on demand.

13. LINE OF CREDIT PROVISIONS. If the type of credit indicated in Section 1 is a
revolving line of credit or a non-revolving line of credit, Borrower agrees that
Lender is under no obligation and has not committed to make any Advances
hereunder. Each Advance hereunder shall be made at the sole option of Lender.

14. DEMAND NOTE. If this note is payable on demand, Borrower acknowledges and
agree that (a) Lender is entitled to demand Borrower's immediate payment in full
of all amounts owing hereunder and (b) neither anything to the contrary
contained herein or in any other loan documents (including but not limited to,
provisions relating to defaults, rights of cure, default rate of interest,
installment payments, late charges, periodic review of Borrower's financial
condition, and covenants) nor any act of Lender pursuant to any such provisions
shall limit or impair Lender's right or ability to require Borrower's payment in
full of all amounts owing hereunder immediately upon Lender's demand.

15. REQUESTS FOR ADVANCES.

(a) Any Advance may be made or interest rate option selected upon the request of
Borrower (if an individual), any of the undersigned (if Borrower consists of
more than one individual), any person or persons authorized in subsection (b) of
this Section 15, and any person or persons otherwise authorized to execute and
deliver promissory notes to Lender on behalf of Borrower.

(b) Borrower hereby authorizes any one of the following individuals to request
Advances and to select interest rate options:
Glenford J. Meyers______________________________________________________________
Stephen F. Loughlin_____________________________________________________________
Brian Bronson___________________________________________________________________
unless Lender is otherwise instructed in writing.

(c) All Advances shall be disbursed by deposit directly to Borrower's account
number 153600038365 with Lender, or by cashier's check issued to Borrower.

(d) Borrower agrees that Lender shall have no obligation to verify the identity
of any person making any request pursuant to this Section 15, and Borrower
assumes all risks of the validity and authorization of such requests. In
consideration of Lender agreeing, at its sole discretion, to make Advances upon
such requests, Borrower promises to pay holder, in accordance with the
provisions of this note, the Principal Balance together with interest thereon
and other sums due hereunder, although any Advances may have been requested by a
person or persons not authorized to do so.

16. PERIODIC REVIEW. Lender will review Borrower's credit accommodations
periodically. At the time of the review, Borrower will furnish Lender with any
additional information regarding Borrower's financial condition and business
operations that Lender requests. The information may include but is not limited
to, financial statements, tax returns, lists of assets and liabilities, agings
of receivables and payables, inventory schedules, budgets and forecasts. If upon
review, Lender, in its sole discretion, determines that there has been a
material adverse change in Borrower's financial condition, Borrower will be in
default. Upon default, Lender shall have all rights specified herein.

17. NOTICES. Any notice hereunder may be given by ordinary mail, postage paid
and addressed to Borrower at the last known address of Borrower as shown on
holder's records. If Borrower consists of more than one person, notification of
any of said persons shall be complete notification of all.

18. ATTORNEY FEES. Whether or not litigation or arbitration is commenced,
Borrower promises to pay all costs of collecting overdue amounts. Without
limiting the foregoing, in the event that holder consults an attorney regarding
the enforcement of any of its rights under this note or any document securing
the same, or if this note is placed in the hands of an attorney for collection
or if suit or litigation is brought to enforce this note or any document
securing the same, Borrower promises to pay all costs thereof including such
additional sums as the court or arbitrator(s) may adjudge reasonable as attorney
fees, including without limitation, costs and attorney fees incurred in any
appellate court, in any proceeding under the bankruptcy code, or in any
receivership and post-judgment attorney fees incurred in enforcing any judgment.

19. WAIVERS; CONSENT. Each party hereto, whether maker, co-maker, guarantor or
otherwise, waives diligence, demand, presentment for payment, notice of
non-payment, protest and notice of protest and waives all defenses based on
suretyship or impairment of collateral. Without notice to Borrower and without
diminishing or affecting Lender's rights of Borrower's obligations hereunder,
Lender may deal in any manner with any person who at any time is liable for, or
provides any real or personal property collateral for, any indebtedness of
Borrower to Lender, including the indebtedness evidenced by this note. Without
limiting the foregoing, Lender may, in its sole discretion: (a) make secured or
unsecured loans to Borrower and agree to any number of waivers, modifications,
extensions and renewals of any length of such loans, including the loan
evidenced by this note; (b) impair, release (with or without substitution of new
collateral), fail to perfect a security interest in, fail to preserve the value
of, fail to dispose of in accordance with applicable law, any collateral
provided by any person; (c) sue, fail to sue, agree not to sue, release, and
settle or compromise with, any person.

20. JOINT AND SEVERAL LIABILITY. All undertakings of the undersigned Borrowers
are joint and several and are binding upon any marital community of which any of
the undersigned are members. Holder's rights and remedies under this note shall
be cumulative.

21. SEVERABILITY. If any term or provision of this note is declared by a court
of competent jurisdiction to be illegal, invalid or unenforceable for any reason
whatsoever, such illegality, invalidity or unenforceability shall not affect the
balance of the terms and provisions hereof, which terms and provisions shall
remain binding and enforceable, and this note shall be construed as if such
illegal, invalid or unenforceable provision had not been contained herein.

22. ARBITRATION.
<PAGE>

(a) Either Lender or Borrower may require that all disputes, claims,
counterclaims and defenses, including those based on or arising from any alleged
tort ("Claims") relating in any way to this note or any transaction of which
this note is a part (the "Loan"), be settled by binding arbitration in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association and Title 9 of the U.S. Code. All Claims will be subject to the
statutes of limitation applicable if they were litigated. This provision is void
if the Loan, at the time of the proposed submission to arbitration, is secured
by real property located outside of Oregon or Washington, or if the effect of
the arbitration procedure (as opposed to any Claims of Borrower) would be to
materially impair Lender's ability to realize on any collateral securing the
Loan.

(b) If arbitration occurs and each party's Claim is less than $100,000, one
neutral arbitrator will decide all issues; if any party's Claim is $100,000 or
more, three neutral arbitrators will decide all issues. All arbitrators will be
active Oregon State Bar members in good standing. All arbitration hearings will
be held in Portland, Oregon. In addition to all other powers, the arbitrator(s)
shall have the exclusive right to determine all issues of arbitrability.
Judgment on any arbitration award may be entered in any court with jurisdiction.

(c) If either party institutes any judicial proceeding relating to the Loan,
such action shall not be a waiver of the right to submit any Claim to
arbitration. In addition, each has the right before, during and after any
arbitration to exercise any number of the following remedies, in any order or
concurrently: (i) setoff; (ii) self-help repossession; (iii) judicial or
non-judicial foreclosure against real or personal property collateral; and (iv)
provisional remedies, including injunction, appointment of receiver, attachment,
claim and delivery and replevin.

23. GOVERNING LAW. This note shall be governed by and construed and enforced in
accordance with the laws of the State of Oregon without regard to conflicts of
law principles; provided, however, that to the extent that Lender has greater
rights or remedies under Federal law, this provision shall not be deemed to
deprive Lender of such rights and remedies as may be available under Federal
law.

                            NEGATIVE PLEDGE AGREEMENT

Date: November 3, 2000

In order to induce U.S. Bank National Association (the "Bank") to make, renew or
extend loans, or other extensions of credit or financial accommodation or to
enter into other credit arrangements, or to continue to make the same available
to RADISYS CORPORATION ("Borrowers") either individually or jointly, the

1.    Borrowers are indebted to Bank under a Promissory Note dated November 3,
      2000 in the original principal amount of $20,000,000.00 (the "Note").

2.    So long as the Borrower is indebted to the Bank on the Note, or any
      extension, renewal or modification thereof, or the Bank has any commitment
      to make loans thereunder, the Borrower shall not, without the prior
      written consent of the Bank, encumber, mortgage, pledge, hypothecate or
      otherwise grant any consensual security interest in or lien upon the
      following described property (the "Property") of Borrower:

      ALL ACCOUNTS, CHATTEL PAPER, DOCUMENTS, INSTRUMENTS, GENERAL INTANGIBLES
AND INVENTORY WHETHER ANY OF THE FOREGOING IS OWNED NOW OR ACQUIRED LATER; ALL
ACCESSIONS, ADDITIONS, REPLACEMENTS, AND SUBSTITUTIONS RELATING TO ANY OF THE
FOREGOING; ALL RECORDS OF ANY KIND RELATING TO ANY OF THE FOREGOING; ALL
PROCEEDS RELATING TO ANY OF THE FOREGOING (INCLUDING INSURANCE, GENERAL
INTANGIBLES AND ACCOUNTS PROCEEDS).

      Nor shall the Borrower permit or suffer to exist any involuntary liens for
unpaid income and withholding taxes or otherwise, judgements, decrees or
otherwise, nor shall the Borrower suffer or permit to exist any form of
execution or other process for the taking of the Property which is not
discharged, dismissed and held for naught within ten (10) days after the
issuance thereof, and in any event, prior to the Borrower losing possessory
right to the Property.

3. In the event that any security interest, lien, claim or other charge of any
kind whatsoever shall come into existence in violation of this Negative Pledge
Agreement, the Borrower shall immediately give notice to the Bank, said notice
to include a complete description of all of the circumstances of such interest -
i.e., claimant, amount, basis of claim, date claimed, dispute as to validity,
etc.

4. Any violation or breach of this Negative Pledge Agreement shall constitute a
default in respect of the Borrower's obligations and indebtedness to the Bank,
for reason of which the Bank shall be entitled at its option to exercise any of
its rights or remedies on default, including immediate acceleration without
notice of all indebtedness of Borrower to the Bank.

5. This Agreement shall be binding upon and inure to the benefit of the Bank,
the Borrower, and their respective successors and assigns and shall be governed
by and interpreted in accordance with the laws of the State of Oregon.

                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of the 17th day of
January, 2000, between PROFESSIONAL DETAILING, INC., a Delaware corporation (the
"Company"), having its principal place of business at 10 Mountainview Road,
Upper Saddle River, New Jersey 07458, and CHRISTOPHER TAMA, residing at 233
South Court, Normandy Beach, NJ 08739 (the "Executive").

                                   WITNESSETH:

      WHEREAS, the Company believes that it would benefit from the application
of the Executive's particular and unique skills, experiences and background in
connection with the management and operation of the Company, and wishes to
employ the Executive as Vice President of Life Cycle X-Tension Company ("LCXT"),
a wholly owned subsidiary of the Company; and.

      WHEREAS, the parties desire by this Agreement to set forth the terms and
conditions of the employment relationship between the Company and the Executive.

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
in this Agreement, the Company and the Executive agree as follows:

      1. Employment and Duties. The Company hereby employs the Executive as Vice
President of LCXT on the terms and conditions set forth in this Agreement and
Executive agrees to accept such employment subject to the terms and conditions
of this Agreement. The Executive shall be responsible for (a) the successful
commercial operations of LCXT clients evidenced by the achievements of strategic
and financial goals periodically established by the Company; (b) establishing
new LCXT clients, with advice and consultation of Company's Chief Executive
Officer (the "CEO") through appropriate business planning; (c) developing
requisite infrastructure for LCXT; (d) managing the commercial operations of the
marketing unit of the Company's TVG, Inc. subsidiary commencing at a point to be
determined by the CEO; and (e) such other duties as are assigned to him by the
CEO which are commensurate with his position with the Company. The Executive
shall report to and be supervised by the Company's CEO. The Executive shall be
based at the Company's offices in Upper Saddle River, New Jersey or such other
place that shall constitute the Company's headquarters.

      The Executive agrees to devote his entire business time, attention and
energies to the business and interests of the Company during the Employment
Period. The Executive shall not accept any other employment or

<PAGE>

engage in any other business activity during the Employment Period; however, the
Executive may devote a reasonable portion of the Executive's personal time to
personal financial affairs and nonprofit public service activities; provided,
however, that such activities do not adversely impact Executive's performance of
his duties hereunder. The Executive agrees to abide by the rules, regulations,
instructions, personnel practices and policies of the Company and any changes
therein which may be adopted from time to time by the Company, including, but
not limited to, those relating to the protection of the Company's proprietary
trade secrets and confidential information.

      2. Term. The term of this Agreement shall commence on January 17, 2000
(the "Commencement Date"), and shall terminate on December 31, 2002, unless
terminated earlier, or extended, in accordance with the terms of this Agreement
(the "Termination Date"). Such term of employment is herein sometimes referred
to as the "Employment Term". The Employment Term shall be extended for
successive one year periods unless either party notifies the other in writing at
least 90 days before the Termination Date, or any anniversary of the Termination
Date, as the case may be, that he or it chooses not to extend the Employment
Term.

      3. Compensation. As compensation for performing the services required by
this Agreement, and during the term of this Agreement, the Executive shall be
compensated as follows:

            (a) Base Compensation. The Company shall pay to the Executive an
annual salary ("Base Compensation") of $175,000, payable in equal installments
pursuant to the Company's customary payroll procedures in effect for its
executive personnel at the time of payment, but in no event less frequently than
monthly, subject to withholding for applicable federal, state, and local taxes.
The Executive may be entitled to such increases in Base Compensation with
respect to each calendar year during the term of this Agreement, as shall be
determined by the Company, in its sole and absolute discretion, based on
periodic reviews of the Executive's performance.

            (b) Incentive Compensation. In addition to Base Compensation, the
Executive may be entitled to receive additional compensation ("Incentive
Compensation") in the discretion of the Company. The Incentive Compensation
shall be pursuant to short-term and/or long-term incentive compensation
programs, pursuant to the Company's Variable Incentive Compensation Program. For
purposes of this Agreement, the Executive's "Pro Rata Share" of Incentive
Compensation for any calendar of the Company shall be a fraction whose numerator
shall be equal to the number of months (or parts of months) during which the
Executive was actually employed by the Company during any such calendar year and
whose denominator shall be the total number of months in such calendar year.

<PAGE>

            (c) Stock Options. Subject to compliance with applicable securities
laws and approval by the Compensation Committee of the Board (the "Compensation
Committee"), the Company shall grant to the Executive an option (the "Stock
Option") to purchase 5,000 shares of Common Stock at a per share price equal to
the last reported sale price of the Common Stock on the Nasdaq National Market
on the Commencement Date. The Stock Option shall become exercisable with respect
to one-third of the shares covered thereby on each of the first, second and
third anniversary of the date of grant so long as the Executive shall remain in
the employment of the Company on such dates. The Stock Option shall contain such
other terms as are customary in options awarded by the Company to employees of
the Company and the subsidiaries under the Company's 1998 Stock Option Plan.

            (d) Initial Payment. The Company shall pay to the Executive in the
first payroll period following the Commencement Date the sum of $15,000 subject
to withholding for applicable federal, state and local taxes to offset expenses
to be incurred by the Executive in connection with his employment.

      4. Employee Benefits. During the Employment Term and subject to the
limitations set forth in this Section 4, the Executive and his eligible
dependents shall have the right to participate in any retirement plans
(qualified and non-qualified), pension, insurance, health, disability or other
benefit plan or program that has been or is hereafter adopted by the Company (or
in which the Company participates), according to the terms of such plan or
program, on terms no less favorable than the most favorable terms granted to
executives of the Company.

      5. Vacation and Leaves of Absence. The Executive shall be entitled to the
normal and customary amount of paid vacation provided to executive officers of
the Company, but in no event less than 15 days during each 12-month period,
beginning on the date of this Agreement. Any vacation days that are not taken in
a given 12-month period shall not accrue or carry-over from year to year. Upon
any termination of this Agreement (a) by the Company for "cause", or (b) by the
Executive other than for "good reason", accrued and unused vacation for the year
in which this Agreement terminates will be paid to the Executive within 10 days
of such termination based on his annual rate of Base Compensation in effect on
the date of such termination. In addition, the Executive may be granted leaves
of absence with or without pay for such valid and legitimate reasons as the
Company in its sole and absolute discretion may determine, and shall be entitled
to the same sick leave and holidays provided to other executive officers of the
Company.

      6. Expenses.

<PAGE>

            (a) Business Expenses. The Executive shall be promptly reimbursed
against presentation of vouchers or receipts for all reasonable and appropriate
expenses incurred by him in connection with the performance of his duties
hereunder.

            (b) Automobile Expense. During the Employment Term, in order to
facilitate the performance of the Executive's duties hereunder, and otherwise
for the convenience of the Company, the Company shall provide the Executive with
an automobile, or shall reimburse the Executive up to $850 per month in
connection with the cost of leasing an automobile, and shall pay or reimburse
Executive (upon presentation of vouchers or receipts) for the reasonable cost of
all maintenance, insurance, repairs, gas and other expenses related to such
automobile.

      7. Indemnification. The Company shall (and is hereby obligated to)
indemnify (including advance payment of expenses, which expenses shall include,
without limitation, reasonable attorneys' fees) the Executive for all actions
taken by Executive as an officer of the Company or the failure of Executive to
take any action in each and every situation where the Company is obligated to
make such indemnification pursuant to applicable law and the relevant portions
of the Company's Certificate of Incorporation and By-Laws.

      8. Termination and Termination Benefits.

            (a) Termination by the Company.

                  (i) For Cause. Notwithstanding any provision contained herein,
the Company may terminate this Agreement at any time during the Employment Term
for "cause". For purposes of this subsection 8(a)(i), "cause" shall mean (1) the
continuing failure by the Executive to substantially perform his duties
hereunder for any reason other than total or partial incapacity due to physical
or mental illness, (2) gross negligence or gross malfeasance on the part of the
Executive in the performance of his duties hereunder that demonstrably cause
harm to the Company, and (3) the conviction of the Executive, by a court of
competent jurisdiction, of a felony or other crime involving moral turpitude.
Termination pursuant to this subsection 8(a)(i) shall be effective immediately
upon giving the Executive written notice thereof stating the reason or reasons
therefor with respect to clauses (2) and (3) above, and 15 days after written
notice thereof from the Company to the Executive specifying the acts or
omissions constituting the failure and requesting that they be remedied with
respect to clause (1) above, but only if the Executive has not cured such
failure within such 15 day period. In the event of a termination pursuant to
this subsection 8(a)(i), the Executive shall be entitled to payment of his Base

<PAGE>

Compensation and the benefits pursuant to Section 4 hereof up to the effective
date of such termination.

                  (ii) Disability. If due to illness, physical or mental
disability, or other incapacity, the Executive shall fail, for a total 90 days
during any 120 day period ("Disability"), to substantially perform the principal
duties required by this Agreement, the Company may terminate this Agreement upon
30 days' written notice to the Executive; provided, however that if the
Executive commences to perform the duties required by this Agreement within such
30-day period and performs such services for 25 out of 30 of the ensuing work
days, then such notice shall be void. In the event of a termination pursuant to
this subsection 8(a)(ii), the Executive shall be (1) paid his Base Compensation
until the Termination Date and his Pro Rata Share of any Incentive Compensation
to which he would have been entitled for the year in which such termination
occurs, and (2) provided with employee benefits pursuant to Section 4, to the
extent available, for the remainder of the Employment Term; provided, however,
that any compensation to be paid to the Executive pursuant to this subsection
8(a)(ii) shall be offset against any payments received by the Executive pursuant
to any policy of disability insurance the premiums of which are paid for by the
Company. Nothing herein shall be construed to violate any Federal or State law
including the Family and Medical Leave Act of 1993, 27 U.S.C.S. ss.2601 et seq.,
and the Americans With Disabilities Act, 42 U.S.C.S. ss.12101 et seq.

            (b) Termination by the Executive. The Executive may terminate this
Agreement at any time during the Employment Term for "good reason" upon 90 days'
written notice to the Company (during which period the Executive shall, if
requested in writing by the Company, continue to perform his duties as specified
under this Agreement). "Good reason" shall mean: (1) the Company's failure to
make any of the payments or provide any of the benefits to the Executive under
this Agreement; (2) the Company's material breach of any provision of this
Agreement; (3) a material reduction in the Executive's responsibilities
(provided, however, "good reason" shall not include a reduction in Executive's
responsibilities if such reduction is a result of Executive's failure to perform
his duties in a manner satisfactory to the Company); or (5) a reduction in the
Executive's Base Compensation (other than a pro rata reduction in Base
Compensation applicable to all senior executives of the Company); provided,
however, that the Company has not cured, or made substantial efforts to cure,
such failure or breach within the aforementioned 90 day period.

            (c) Termination Compensation. In the event of a termination of this
Agreement (a) by the Company without cause (as defined in subsection 8(a)(i)
hereof), or (b) by the Executive for "good reason" pursuant

<PAGE>

to subsection 8(b) above, the Executive shall be paid, in consideration of the
post-termination non-compete and non-solicitation agreements set forth in
Section 10: (1) his Base Compensation up to the effective date of such
termination; (2) his full share of any Incentive Compensation payable to him for
the year in which the termination occurs; and (3) a lump sum payment
(hereinafter "Termination Compensation") to the Executive equal to the net
present value of 50% of the average cash compensation (including Base
Compensation and Incentive Compensation) paid to, or accrued for, the Executive
in the calendar year immediately preceding the calendar year in which the
termination occurs; provided, however, that, if Termination Compensation becomes
due in the first year of the term of this Agreement it shall be equal to 60% of
Base Compensation. Payment of Termination Compensation to the Executive shall
occur no later than 14 days following the effective date of the Executive's
termination. For purposes of this subsection 8(c), the date of termination of
the Executive's employment shall be date on which the Executive ceases to
perform services for the Company.

            (d) Stock Options and Other Benefits. In the event that the
Executive is terminated for reasons other than for "cause" or in the event the
Executive terminates this Agreement for "good reason", any stock options then
held by the Executive and/or any other benefits subject to specified vesting
criteria, shall immediately vest in the Executive; provided, however, all stock
options then held by the Executive and/or any other benefits subject to
specified vesting criteria shall expire and/or terminate 90 days after the date
this Agreement is terminated pursuant to subsections 8(a)(i) or 8(b). The
Company agrees to take such steps and to execute such documents as shall be
necessary to effectuate the foregoing.

            (e) Death Benefit. Notwithstanding any other provision of this
Agreement, this Agreement shall terminate on the date of the Executive's death.
In such event the Company shall pay Executive's Base Salary to his wife, if she
survives him, or, if she does not survive him, in equal shares to his children
who survive him, through the end of the month in which such death occurs. In
addition, the Company shall pay to Executive's wife, if she survives him, or, if
she does not survive him, in equal shares to his children who survive him, the
Pro Rata Share of any Incentive Compensation to which Executive would have been
entitled for the year in which such death occurs.

            (f) No Mitigation. The Executive shall not be required to mitigate
the amount of any payments provided for by this Agreement by seeking employment
or otherwise, nor shall the amount of any

<PAGE>

 payment or benefit provided in this Agreement be reduced
by any compensation or benefit earned by the Executive after termination of his
employment.

            (g) Survival. The provisions of Sections 7, 8, 9, 10, 11, and 12
shall survive the termination of this Agreement.

      9. Company Property. All advertising, promotional, sales, suppliers,
manufacturers and other materials or articles or information, including without
limitation data processing reports, customer lists, customer sales analyses,
invoices, product lists, price lists or information, samples, or any other
materials or data of any kind furnished to the Executive by the Company or
developed by the Executive on behalf of the Company or at the Company's
direction or for the Company's use or otherwise in connection with the
Executive's employment hereunder, are and shall remain the sole and confidential
property of the Company; if the Company requests the return of such materials at
any time during or at or after the termination of the Executive's employment,
the Executive shall immediately deliver the same to the Company.

      10. Covenant Not To Compete.

            (a) No Solicitation or Competition. During the term of this
Agreement and for a period of twelve months after termination of the Executive's
employment with the Company for any reason, the Executive shall not, directly or
indirectly, solicit, induce, encourage or attempt to influence any client,
customer, employee, consultant, independent contractor, salesman or supplier of
the Company to cease to do business or terminate his employment with the
Company, and shall not engage in (as a principal, partner, director, officer,
agent, employee, consultant or otherwise) or be financially interested in any
business competing with the Company anywhere in the United States. Nothing
contained in this Section 10 shall prevent the Executive from holding for
investment not more than five percent (5%) of any class of equity securities of
a company whose securities are publicly traded or from engaging in any
activities that are not in competition with the business activities of the
Company.

            (b) Confidentiality of Company Property. During the effectiveness of
this Agreement and at all times thereafter, the Executive shall not use for his
personal benefit, or disclose, communicate or divulge to, or use for the direct
or indirect benefit of any person, firm, association or company other than the
Company, any material referred to in Section 9 above unless such material has
been made publicly available by the Company. Company Property includes
"Confidential Information" defined as any information disclosed to the Executive
or known to the Executive as a consequence of, or through the Executive's
employment with the Company (including

<PAGE>

information conceived, originated, discovered or developed by the Executive),
about the Company or the Company's clients or customers' business operations,
processes, products, research and development, manufacturing methods, marketing,
sales costs, pricing, inventions, improvements, discoveries and ideas (whether
patentable or not), and financial information. Confidential Information also
means any formula, pattern, procedure, method, device or compilation of
information which is used in the company's business or the company's clients or
customers' business, and which gives the Company and/or its clients and
customers an opportunity to obtain an advantage over competitors. The Executive
understand that as a manager the Executive will be exposed to a broad base of
information about the company operations nationwide and will receive detailed
information about the Company's customers from the Company and from the
employees the Executive supervise.

            (c) Saving Clause. If the period of time or the area specified in
subsection (a) above should be adjudged unreasonable in any proceeding, then the
period of time shall be reduced by such number of months or the area shall be
reduced by the elimination of such portion thereof or both so that such
restrictions may be enforced in such area and for such time as is adjudged to be
reasonable. If the Executive violates any of the restrictions contained in the
foregoing subsection (a), the restrictive period shall not run in favor of the
Executive from the time of the commencement of any such violation until such
time as such violation shall be cured by the Executive to the satisfaction of
Company.

      11. Executive's Representation and Warranties. The Executive represents
and warrants to the Company as follows:

            (a) All facts concerning the Executive's background, education,
experience and employment history as described to the Company by the Executive
are true and correct in all material respects;

            (b) The Executive's execution of this Agreement and employment with
the Company does not and will not conflict with any obligations that the
Executive has to any current or former employer, any other individual,
corporation, partnership, association, trust or any other entity or
organization, including any instrumentality of government;

            (c) The Executive has not brought to the Company, and will not bring
to the Company, any materials, documents or other property of any nature that is
the confidential property of another party or entity;

            (d) All files, records, compilations, reports, studies, manuals,
memoranda, notebooks, documents, financial reports and statements,
correspondence, and other confidential information whether prepared

<PAGE>

by the Executive or otherwise coming into the possession of the Executive, and
all copies thereof, are, and shall remain, the exclusive property of the
Company, and shall be delivered immediately to the Company in the event o the
Executive's termination or at any other time if requested by the Company.

            (e) Executive acknowledges that the foregoing representation and
warranties are a material inducement to the Company entering into this Agreement
and that in the event that any of these representation and warranties, Executive
agrees to indemnify and hold harmless the Company from and against any and all
claims, actions, losses and damages (including but not limited to, reasonable
attorneys' fees and costs) incurred by the Company, and the Company shall have
the right to terminate Executive for cause.

      12. Miscellaneous.

            (a) Integration; Amendment. This Agreement constitutes the entire
agreement between the parties hereto with respect to the matters set forth
herein and supersedes and renders of no force and effect all prior
understandings and agreements between the parties with respect to the matters
set forth herein. No amendments or additions to this Agreement shall be binding
unless in writing and signed by both parties.

            (b) Severability. If any part of this Agreement is contrary to,
prohibited by, or deemed invalid under applicable law or regulations, such
provision shall be inapplicable and deemed omitted to the extent so contrary,
prohibited, or invalid, but the remainder of this Agreement shall not be invalid
and shall be given full force and effect so far as possible.

            (c) Waivers. The failure or delay of any party at any time to
require performance by the other party of any provision of this Agreement, even
if known, shall not affect the right of such party to require performance of
that provision or to exercise any right, power, or remedy hereunder, and any
waiver by any party of any breach of any provision of this Agreement shall not
be construed as a waiver of any continuing or succeeding breach of such
provision, a waiver of the provision itself, or a waiver of any right, power, or
remedy under this Agreement. No notice to or demand on any party in any case
shall, of itself, entitle such party to other or further notice or demand in
similar or other circumstances.

            (d) Power and Authority. The Company represents and warrants to the
Executive that it has the requisite corporate power to enter into this Agreement
and perform the terms hereof; that the execution, delivery and performance of

confirmed facsimile transmission and followed promptly by mail, or mailed by
registered or certified mail (return receipt requested), postage prepaid, to the
parties at their respective addresses (or at such other address for a party as
shall be specified by like notice; provided that notices of a change of address
shall be effective only upon receipt thereof) as set forth in the preamble to
this Agreement or to any other address or addressee as any party entitled to
receive notice under this Agreement shall designate, from time to time, to
others in the manner provided in this subsection 12(g) for the service of
Notices.

            Any notice delivered to the party hereto to whom it is addressed
shall be deemed to have been given and received on the day it was received;
provided, however, that if such day is not a business day then the notice shall
be deemed to have been given and received on the business day next following
such day. Any notice sent by facsimile transmission shall be deemed to have been
given and received on the business day next following the day of transmission.

            (h) Arbitration; Remedies. Any dispute or controversy arising under
this Agreement or as a result of or in connection with Executive's employment
(other than disputes arising under Section 10) shall be arbitrated and settled
pursuant to the National Rules for the Resolution of Employment Disputes of the
American Arbitration Association which are then in effect. This provision shall
also apply to any and all claims that may be brought under any federal or state
anti-discrimination or employment statute, rule or regulation, including, but
not limited to, claims under; the National Labor Relations Act; Title VII of the
Civil Rights Act; Section 1981 through 1988 of Title 42 of the United States
Code; the Employee Retirement Income

<PAGE>

Security Act; the Immigration Reform and Control Act; the Americans with
Disabilities Act; the Age Discrimination in Employment Act; the Fair Labor
Standards Act; the Occupational Safety and Health Act; the Family and Medical
Leave Act and/or the Equal Pay Act. The decision of the arbitrator and award, if
any, is final and binding on the parties and the judgement may be entered in any
court having jurisdiction thereof. The parties will agree upon an arbitrator
from the list of labor arbitrators supplied by the American Arbitration
Association. The parties understand and agree, however, that disputes arising
under Section 10 of this Agreement may be brought in a court of law or equity
without submission to arbitration.

            (i) Jurisdiction. Except as otherwise provided for herein, each of
the parties: (a) submits to the exclusive jurisdiction of any state court
sitting in Bergen County, New Jersey or federal court sitting in New Jersey in
any action or proceeding arising out of or relating to this Agreement; (b)
agrees that all claims in respect of the action or proceeding may be heard and
determined in any such court; (c) agrees not to bring any action or proceeding
arising out of or relating to this Agreement in any other court; and (d) waives
any right such party may have to a trial by jury with respect to any action or
proceeding arising out of or relating to this Agreement. Each of the parties
waives any defense of inconvenient forum to the maintenance of any action or
proceeding so brought and waives any bond, surety or other security that might
be required of any other party with respect thereto. Any party may make service
on another party by sending or delivering a copy of the process to the party to
be served at the address and in the manner provided for giving of notices in
Section 11. Nothing in this Section 14, however, shall affect the right of any
party to serve legal process in any other manner permitted by law.

            (j) Number of Days. In computing the number of days for purposes of
this Agreement, all days shall be counted, including Saturdays, Sundays and
holidays; provided, however, that if the final day of any time period falls on a
Saturday, Sunday or holiday on which federal banks are or may elect to be
closed, then the final day shall be deemed to be the next day which is not a
Saturday, Sunday or such holiday.
