The third party software excluded from delivery into escrow pursuant to the
provisions of this SECTION 2(C), shall be referred to herein as the "Excluded
Software".

             (d) ATC and NetChemistry shall engage SilverStream to verify that
the Software Deliverables contain all of the Work Product and NetChemistry
proprietary software Utilized to Operate the ATCADVANTAGE Web Site, in
accordance with the following procedure:

                 (1) SilverStream shall designate a single individual (the
"Verifying Employee "), who shall be an employee of SilverStream, to conduct the
verification.

                 (2) The Verifying Employee shall be free of any conflicts of
interest, whether actual, potential, or apparent, (including, without
limitation, any current or past applications for or solicitations of employment,
or other communications with respect to possible employment, with any of the
parties to this agreement), except any such conflicts of interest which may be
waived in writing by ATC and NetChemistry. The Verifying Employee may be
requested by either ATC or NetChemistry to disclose any and all conflicts of
interest, whether actual, potential, or apparent, prior to commencement of
performance of his verification activities hereunder, and to verify the absence
of any. ATC and NetChemistry each hereby represent and warrant to the other
that, prior to the commencement of verification activities hereunder by the
Verifying Employee, they will disclose in writing to the other any known or
suspected conflicts of interest, whether actual, potential, or apparent, on the
part of the Verifying Employee. ATC and NetChemistry shall be prohibited, for a
period of two years from the date of this agreement, from directly or indirectly
employing or hiring, as an employee, consultant, or otherwise, the Verifying
Employee; provided, however, that nothing herein contained shall prevent either
party from engaging SilverStream in any manner whatsoever, so long as such
engagement does not require, induce, or encourage any breach of the obligations
of confidentiality undertaken by the Verifying Employee.

                 (3) The Verifying Employee shall execute a confidentiality
agreement in favor of NetChemistry and ATC, in form and substance acceptable to
NetChemistry and ATC, with respect to the source code and any other confidential
material proprietary to NetChemistry and ATC provided as part of the Software
Deliverables.

                 (4) NetChemistry shall make available to the Verifying Employee
access to the operating hardware and software utilized by NetChemistry to
operate the ATCADVANTAGE Web Site. The Verifying Employee shall have the
opportunity, and shall be

                                       5

<PAGE>

provided with the necessary equipment and facilities, to make copies of any or
all of the software Utilized to Operate the ATCADVANTAGE Web Site, aside from
any Excluded Software, as deemed necessary by the Verifying Employee to verify
that the Software Deliverables constitute all of the software "Utilized to
Operate the ATCADVANTAGE Web Site" with the exception of any Excluded Software.
Any such software copied by the Verifying Employee shall be delivered,
immediately upon completion of copying at the NetChemistry facilities, by the
Verifying Employee, to an authorized agent of Escrow Agent, who shall transport
such copies to the offices of Escrow Agent to be deposited and held in the
Escrow Account.

                 (5) The parties shall use their best efforts and shall take all
steps necessary and appropriate to arrange for and complete the verification and
the close of escrow no later than August 7, 2001. Unless delayed as a result of
the inability of the Verifying Employee to complete his verification by such
date, final verification shall occur on August 7, 2001. A preliminary
verification shall be conducted as soon as possible following the date of this
Escrow Agreement and before August 7, 2001, so that the only remaining
verification required on August 7, 2001, will be to update the Software
Deliverables with any additional Work Product created during the interim.
Following the preliminary verification, the Verifying Employee shall provide the
parties with written notice of the results of the preliminary verification.

                 (6) All costs, expenses, and charges incurred for the services
rendered by SilverStream and the Verifying Employee shall be borne by ATC, and
ATC shall indemnify NetChemistry and hold it harmless from and against any such
costs, expenses, or charges.

             (e) Upon final verification of the content of the Software
Deliverables, the Verifying Employee shall execute a Verification Notice in the
form attached hereto as EXHIBIT A, and deliver such notice to ATC, NetChemistry,
Escrow Agent, and Eagle. The Verification Notice shall identify any material
exceptions between the Software Deliverables and the modules currently Utilized
to Operate the ATCADVANTAGE Web Site.

             (f) As soon as practicable after receipt of the Verification
Notice, NetChemistry and ATC shall discuss the nature and extent of the material
exceptions identified in the Verification Notice, if any. Upon the parties
mutually acceptable resolution of any identified material exceptions, the
parties shall execute the escrow instructions in the form of closing notice
attached hereto as EXHIBIT B, and ATC shall deliver the Escrow Funds forthwith.
The date of the parties' mutually acceptable resolution of any identified
material exceptions shall be referred to as the "Verification Date."

             (g) In the event that there are no material exceptions identified
in the Verification Notice, the date of the Verification Notice shall be deemed
to be the "Verification Date", ATC shall deliver the Escrow Funds forthwith, and
the parties shall execute the Closing Notice.

                                       6

<PAGE>

             (h) In the event ATC is unable to deliver the Escrow Funds on the
Verification Date, ATC shall have one business day after receipt of the
Verification Notice within which to deliver the Escrow Funds.

             (i) In the event that the parties are not able to agree on a
mutually acceptable resolution of any identified material exceptions, the
parties shall so notify Escrow Agent. As soon as practicable upon receipt of
notification that the parties cannot mutually agree on an acceptable resolution,
or if the Verification Date has not occurred by August 31, 2001, Escrow Agent
shall return (1) to NetChemistry, any Software Deliverables in the Escrow
Account, the counterpart original Settlement Agreement executed by NetChemistry,
and the Stipulation for Dismissal; (2) to ATC, the Note, unless otherwise paid
with Escrow Funds in the Escrow Account, together with the counterpart original
Settlement Agreement executed by ATC; and (3) to ATC, the Escrow Funds, if any.
As a matter with which the Escrow Agent need not be concerned, substantially
contrary with the deliveries specified in the preceding sentence, NetChemistry
shall return to Eagle the Guaranty.

             3. DISBURSEMENT OF SOFTWARE DELIVERABLES AND ESCROW FUNDS.

             (a) Upon receipt of (A) the Closing Notice duly executed by ATC and
NetChemistry, and (B) the Escrow Funds in exchange for the Note, Escrow Agent
shall deliver or transfer the Escrow Funds to NetChemistry, shall deliver the
Software Deliverables and the Stipulation for Dismissal to ATC, and shall
deliver to ATC and NetChemistry, respectively, the counterpart originals of the
Settlement Agreement, as duly executed by the other party thereto.

             (b) Upon receipt of either or both of the Closing Notice duly
executed by ATC and NetChemistry, or the unqualified Verification Notice from
SilverStream, and in the event that the Escrow Funds have not been deposited
with Escrow Agent in exchange for the Note within three business days following
the later of August 7, 2001, or the date of receipt of the Verification Notice,
Escrow Agent shall deliver or transfer (1) to NetChemistry, any Software
Deliverables in the Escrow Account, the counterpart original Settlement
Agreement executed by NetChemistry, the Stipulation for Dismissal, and the Note;
and (2) to ATC, the counterpart original Settlement Agreement executed by ATC.

             4.MAINTENANCE OF RECORDS. Escrow Agent shall maintain accurate
records of all transactions hereunder. Promptly after the termination of the
escrow, Escrow Agent shall provide ATC and NetChemistry with a complete and
accurate account of the transactions. ATC and NetChemistry shall also have
access to such books and records relating to the Escrow Account at all
reasonable times during normal business hours upon reasonable notice to the
Escrow Agent; PROVIDED, HOWEVER, that ATC shall have no access to the Software
Deliverables prior to the close of escrow hereunder.

                                       7

<PAGE>

             5. EXCULPATION AND INDEMNIFICATION OF ESCROW AGENT. Each of the
parties hereto agree:

             (a) to authorize Escrow Agent, in the event of any conflicting
demands made upon it concerning this Escrow Agreement or the escrow, at its
election, to hold any money, documents, and Software Deliverables deposited
hereunder until it receives mutual instructions by all parties or until a civil
action shall have been fully concluded in a court of competent jurisdiction,
determining the rights of the parties. In the alternative, Escrow Agent may, at
its discretion, at any time, commence a civil action to interplead any
conflicting demands to a court of competent jurisdiction.

             (b) to indemnify and hold harmless Escrow Agent for, from, and
against all costs, damages, attorneys' fees, expenses, and liabilities, which it
may incur or sustain in connection with this Escrow Agreement or any court
action arising therefrom and will pay same on demand. This right of
indemnification shall survive the termination of this Escrow Agreement, and/or
the removal or resignation of the Escrow Agent.

             (c) that unless otherwise herein expressly provided, the Escrow
Agent shall not be held liable for any action taken or omitted under this Escrow
Agreement, so long as it shall have acted in good faith and without negligence.
The Escrow Agent shall have no responsibility to inquire into or determine the
genuineness, authenticity, or sufficiency of any documents or instruments
submitted to it in connection with its duties hereunder. The Escrow Agent shall
be entitled to deem the signatories of any document or instrument submitted to
it hereunder as being authorized to sign such documents or instruments on behalf
of the party submitting such documents or instruments, and shall be entitled to
rely upon the genuineness of signatures or such signatories without inquiry and
without requiring substantiating evidence. At the option of Escrow Agent,
facsimile copies of documents may be accepted as originals.

             (d) to grant Escrow Agent a lien on all escrowed assets for all
fees, expenses, taxes, indebtedness, and other financial obligations that may
become owing to Escrow Agent arising hereunder, including any indemnities
prescribed herein. In all cases, Escrow Agent may deduct any unpaid fees, with
prior notice, before final disbursement of the escrow funds. To the extent that
Escrow Agent deducts any unpaid fees from the final disbursement of escrow
funds, the party otherwise entitled to receipt of the escrow funds shall be
promptly reimbursed by the other party for any amount deducted from the escrow
funds attributable to any failure by the latter to pay its share of the Escrow
Agent's fees.

             6.COMPENSATION OF ESCROW AGENT. For all services rendered by Escrow
Agent hereunder, Escrow Agent shall be entitled to receive from ATC and
NetChemistry the fees (the "Fees") described and calculated on the fee schedule
attached as EXHIBIT C hereto. The Fees earned shall be payable on the earliest
to occur of: (i) any date the Escrow Funds and Software Deliverables are
disbursed in accordance with SECTION 3(A) hereof, (ii) the occurrence of the
events set forth in SECTION 2(I) or SECTION 3(B) hereof, or (iii) the
resignation of the Escrow Agent as set forth in SECTION 8 hereof. The Fees shall
be payable by and prorated

                                       8

<PAGE>

equally among ATC and NetChemistry. To the extent such fees and expenses are not
paid by the undersigned, the foregoing shall be paid from the cash in the Escrow
Funds after written notice from the Escrow Agent to the undersigned.

             7.FURTHER ASSURANCES. From time to time, on and after the date
hereof, the parties shall deliver, or cause to be delivered, to Escrow Agent
such further documents and instruments and shall do any further acts, or cause
such further acts to be done as Escrow Agent shall reasonably request (it being
understood that Escrow Agent shall have no obligation to make any such request)
to carry out more effectively the provisions and purposes of this Escrow
Agreement, to evidence compliance herewith or to assure itself that it is
protected in acting hereunder.

             8.RESIGNATION. Escrow Agent may resign at any time and be
discharged from its duties as Escrow Agent hereunder by giving the other parties
hereto at least fifteen (15) business days' notice hereof. As soon as
practicable after its resignation, Escrow Agent shall turn over to a successor
Escrow Agent appointed jointly by ATC and NetChemistry all monies and property
held hereunder (less such amount as Escrow Agent is entitled to retain pursuant
to SECTION 5) upon presentation of the document appointing the new Escrow Agent
and its acceptance thereof. If no new Escrow Agent is so appointed within a
thirty (30) day period following such notice of resignation, Escrow Agent may
deposit the aforesaid monies and property with any court it deems appropriate,
or may return the materials deposited to the parties who originally deposited
such materials with Escrow Agent.

             9.ADDITIONAL AGREEMENTS OF ATC AND NETCHEMISTRY. As additional
covenants effective only as between ATC and NetChemistry, and with which Escrow
Agent need not be concerned, ATC and NetChemistry agree as follows:

             (a) CONDITIONAL STAY OF FURTHER PROCEEDINGS. All proceedings in
American Arbitration Association, Orange County, California, Demand for
Arbitration, entitled NETCHEMISTRY, INC., V. AUTOTRADECENTER.COM, ET. AL, filed

or motions will be urged until any of the following occur: (1) the escrow closes
hereunder and the Stipulation for Dismissal has been filed, or (2) escrow is
terminated without closing due to the failure of the conditions necessary to
closing; or (3) August 31, 2001.

             (b) COMPLETION OF SERVICES. NetChemistry shall continue to provide,
through and including August 7, 2001, the services pursuant to the Professional
Consulting Services Agreement dated March 21, 2001, as directed by a
representative of ATC through an individual specified by NetChemistry, in the
manner provided for in and in accordance with the March 21, 2001, Development

                           LOAN MODIFICATION AGREEMENT

This Loan  Modification  Agreement is entered into as of August 2, 2001,  by and
between Spectrian Corporation ("Borrower") and Silicon Valley Bank ("Bank").

1. DESCRIPTION OF EXISTING  INDEBTEDNESS:  Among other indebtedness which may be
owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among other
documents, an Amended and Restated Loan and Security Agreement,  dated August 9,
1999,  as may be amended  from time to time,  (the "Loan  Agreement").  The Loan
Agreement  provided for, among other things,  a Committed  Revolving Line in the
original  principal amount of Ten Million Dollars  ($10,000,000).  Defined terms
used but not otherwise  defined herein shall have the same meanings as set forth
in the Loan Agreement.

Hereinafter,  all indebtedness owing by Borrower to Bank shall be referred to as
the "Indebtedness."

2.        DESCRIPTION OF COLLATERAL. Repayment of the Indebtedness is secured by
the  Collateral as described in the Loan Agreement.

Hereinafter,  the  above-described  security documents and guaranties,  together
with  all  other  documents  securing  repayment  of the  Indebtedness  shall be
referred to as the "Security  Documents".  Hereinafter,  the Security Documents,
together with all other documents  evidencing or securing the Indebtedness shall
be referred to as the "Existing Loan Documents".

3.       DESCRIPTION OF CHANGE IN TERMS.

         A.       Modification(s) to Loan Agreement.

                  1.    Subsection  (iii) under Section 6.7 entitled  "Financial
                        Covenants" is hereby  amended in its entirety to read as
                        follows:

                        Profitability.  Borrower  will have a minimum net profit
                        of $1 for each quarter net of any realized  gain or loss
                        on the sale of the 1,000,000  shares of CREE Inc. common
                        stock and  related  options,  except that  Borrower  may
                        suffer losses not to exceed  $2,500,000 for the quarters
                        ending September 30, 2001 and December 31, 2001.

         B.       Waiver of Financial Covenant Default(s)

                  1.    Bank hereby waives Borrower's existing default under the
                        Loan Agreement by virtue of Borrower's failure to comply
                        with the Profitability covenant as of quarter ended June
                        30, 2001. Bank's waiver of Borrower's compliance of this
                        covenant  shall  apply  only  to the  foregoing  period.
                        Accordingly,  for the period ended  September  30, 2001,
                        Borrower shall be in compliance  with this covenant,  as
                        amended herein.

                        Bank's  agreement to waive the  above-described  default
                        (1) in no way shall be deemed an  agreement  by the Bank
                        to waive Borrower's  compliance with the above-described
                        covenant  as of all other  dates and (2) shall not limit
                        or impair the Bank's right to demand strict  performance
                        of this covenant as of all other dates and (3) shall not
                        limit  or  impair  the  Bank's  right to  demand  strict
                        performance of all other covenants as of any date.

4.       CONSISTENT  CHANGES.  The Existing Loan  Documents  are hereby  amended
wherever necessary to reflect the changes described above.

5.       NO DEFENSES  OF  BORROWER.  Borrower  (and each  guarantor  and pledgor
signing  below) agrees that, as of the date hereof,  it has no defenses  against
the obligations to pay any amounts under the Indebtedness.
<PAGE>

6.       PAYMENT OF LOAN FEE. Borrower shall pay Bank a fee in the amount of Two
Thousand  Five  Hundred and 00/100  Dollars  ($2,500.00)  ("Loan  Fee") plus all
out-of-pocket expenses.

7.       CONTINUING  VALIDITY.  Borrower (and each guarantor and pledgor signing
below) understands and agrees that in modifying the existing Indebtedness,  Bank
is relying upon Borrower's  representations,  warranties, and agreements, as set
forth in the Existing Loan Documents.  Except as expressly  modified pursuant to
this Loan  Modification  Agreement,  the terms of the  Existing  Loan  Documents
remain unchanged and in full force and effect. Bank's agreement to modifications
to the existing Indebtedness pursuant to this Loan Modification  Agreement in no
way shall obligate Bank to make any future  modifications  to the  Indebtedness.
Nothing in this Loan  Modification  Agreement shall constitute a satisfaction of
the  Indebtedness.  It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly  released by Bank in writing.  Unless expressly  released  herein,  no
maker,  endorser,  or  guarantor  will  be  released  by  virtue  of  this  Loan
Modification Agreement.  The terms of this paragraph apply not only to this Loan
Modification Agreement, but also to all subsequent loan modification agreements.

8.       CONDITIONS.  The effectiveness of this Loan  Modification  Agreement is
conditioned upon payment of the Loan Fee.

         This Loan  Modification  Agreement  is  executed  as of the date  first
written above.

BORROWER:                                      BANK:
