                                 LOAN AGREEMENT


         This LOAN AGREEMENT (this "Loan Agreement"), dated as of October 7,
2002 is entered into by and between SIRENZA MICRODEVICES, INC., a Delaware
corporation ("Lender") and VARI-L COMPANY, INC., a Colorado corporation
("Borrower").

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing and of the covenants,
conditions and agreements set forth herein, the parties agree as follows:

ARTICLE 1. INTERPRETATION.

         1.1 Definitions. Unless otherwise indicated in this Loan Agreement,
each term set forth in Schedule I, when used in this Loan Agreement, shall have
the respective meaning given to that term in Schedule I or in the provision of
this Loan Agreement referenced in Schedule I.

         1.2 GAAP. Unless otherwise indicated in this Loan Agreement, all
accounting terms used in this Loan Agreement shall be construed, and all
accounting and financial computations hereunder or thereunder shall be computed,
in accordance with GAAP. The term "GAAP" shall mean generally accepted
accounting principles and practices as in effect in the United States of America
from time to time, consistently applied.

         1.3 Governing Law. This Loan Agreement and each of the other Loan
Documents shall be governed by and construed in accordance with the laws of the
State of California without reference to conflicts of law rules.

         1.4 Construction. Each of this Loan Agreement and the other Loan
Documents is the result of negotiations among, and has been reviewed by,
Borrower, Lender and their respective counsel. Accordingly, this Loan Agreement
and the other Loan Documents shall be deemed to be the product of all parties
hereto, and no ambiguity shall be construed in favor of or against Borrower or
Lender.

         1.5 Entire Agreement. This Loan Agreement and each of the other Loan
Documents, taken together, constitute and contain the entire agreement of
Borrower and Lender and supersede any and all prior agreements, negotiations,
correspondence, understandings and communications among the parties, whether
written or oral, respecting the subject matter hereof.

         1.6 Calculation of Interest and Fees. All calculations of interest and
fees under this Loan Agreement and the other Loan Documents for any period shall
include the first day of such period and exclude the last day of such period.




ARTICLE 2. LOANS

         2.1 Tranche A Loan. Subject to the terms and conditions of this Loan
Agreement, Lender agrees to advance to Borrower a term loan (the "Tranche A
Loan") in an aggregate principal amount not to exceed $1,353,861.80 to be used
to payoff existing Indebtedness to Wells Fargo Business Credit Inc. Borrower may
not reborrow the principal amount of the Tranche A Loan after repayment or
prepayment thereof.

         2.2 Tranche B Loans. Subject to the terms and conditions of this Loan
Agreement, Lender agrees to advance to Borrower, from time to time, term loans
(each, a "Tranche B Loan" and together with the Tranche A Loan, the "Loans", and
each a "Loan") according to Schedule II attached hereto (the "Funding
Schedule"), in an aggregate principal amount not to exceed $3,946,138.20 (the
"Tranche B Commitment"). Each month Borrower may request a Tranche B Loan in a
principal amount up to the sum of (i) the principal amount of Tranche B Loans
permitted to be advanced to the date of requested advance pursuant to the
Funding Schedule plus (ii) any Excess Amount. The term "Excess Amount" shall
mean the aggregate principal amount of Tranche B Loans permitted to be advanced
to the date of requested advance pursuant to the Funding Schedule minus the
aggregate amount of Tranche B Loans actually advanced to the date of requested
advance. In no event shall the aggregate principal amount of Tranche B Loans
advanced pursuant to this Loan Agreement exceed the Tranche B Commitment. No
more than one Tranche B Loan shall be advanced per calendar month (except that
Borrower may make two advances in the month of October 2002, provided that in no
event shall the aggregate principal amount of Loans advanced in such month
exceed $1,200,000) and each Tranche B Loan shall be made on a date at least
three (3) Business Days after the delivery to Lender in the manner specified in
Section 7.1 of a notice of borrowing in the form of Schedule III hereto (the
"Notice of Borrowing"). Borrower may not reborrow the principal amount of any
Tranche B Loan after repayment or prepayment thereof.

         2.3 Interest. Borrower shall pay interest at Maturity on the unpaid
principal amount of the Loans from the date of each such Loan until paid in
full, at a rate per annum equal to twenty five percent (25%). All computations
of such interest shall be based on a year of twelve thirty (30) day months.

         2.4 Maturity. Unless earlier prepaid or accelerated, all outstanding
principal and accrued interest under the Loans are due and payable in full on
September 25, 2003.

         2.5 Prepayments.

                  (a) Optional Prepayment

                           (1) Tranche A Loan. Provided that there are no
outstanding Tranche B Loans, at its option, Borrower may, upon five (5) Business
Days' written notice to Lender, prepay all, but not less than all of the Tranche
A Loan, provided that such prepayment shall include, all outstanding principal
on the Tranche A Loan, all accrued interest to the date of prepayment thereon
and all other fees and expenses due to Lender under the Loan Documents.

                           (2) Tranche B Loans. At its option, Borrower may,
upon five (5) Business Days' written notice to Lender, prepay all or part of any
Tranche B Loan, provided that such prepayment shall include, all outstanding
principal on the Tranche B Loan, all accrued interest to the date of prepayment
and all other fees and expenses due to Lender under the Loan Documents.



                                      -2-


                           (3) Prepayment Fee. In the event that (i) a Change of
Control shall occur within 180 days following a date of prepayment pursuant to
this Section 2.5(a) upon which all outstanding Loans have been paid in full or
(ii) Borrower shall enter into a definitive acquisition agreement with a Person
other than Lender within 180 days following a date of prepayment upon which all
outstanding Loans have been paid in full that would result in a Change of
Control, then in either case, Borrower expressly agrees to pay (whether or not
any Obligations remain outstanding and whether or not Lender has any commitment
to make Loans hereunder) to Lender the Prepayment Fee upon the occurrence of
either event referenced in subsection (i) or (ii) of this sentence. Borrower's
express agreement to pay the Prepayment Fee pursuant to the terms set forth in
the previous sentence shall survive the termination of this Loan Agreement.

                  (b) Mandatory Prepayment of Loans. Upon the earlier of (i) the
fifth Business Day following the date of execution of a definitive agreement
with a Person other than Lender that would result in a Change of Control, or
(ii) the occurrence of a Change of Control, then in either case:

                           (1) Borrower shall, at Lender's option, either (A)
prepay in full all outstanding principal amounts due under the Tranche A Loan,
all accrued interest to the date of prepayment and all other fees and expenses
due under the Loan Documents, or (B) convert all outstanding principal amounts
due under the Tranche A Loan into Borrower's Equity Securities pursuant to the
conversion provisions contained in the Tranche A Note and pay to Lender all
accrued interest to the date of conversion and all other fees and expenses due
under the Loan Documents;

                           (2) Borrower shall prepay in full all outstanding
principal amounts due under the Tranche B Loans, all accrued interest to the
date of prepayment, and all other fees and expenses due under the Loan
Documents; and

                           (3) Borrower shall pay to Lender the Prepayment Fee.

                  (c) Application of Prepayments. All prepayments hereunder
shall be applied first to unpaid fees, costs and expenses then due and payable
under this Loan Agreement or the other Loan Documents, second to accrued
interest then due and payable under this Loan Agreement or the other Loan
Documents, third to the Prepayment Fee, if any, and finally to reduce the
principal amount of outstanding Loans.

                  (d) Conversion. At Lender's option, the principal amount of
the Tranche A Loan may be converted into Borrower's Equity Securities pursuant
to the conversion provisions contained in the Tranche A Note.

         2.6 Application to Acquisition Consideration. In the event that Lender
and Borrower enter into a definitive acquisition agreement that would result in
Lender acquiring Borrower, or all or substantially all of the assets of
Borrower, then all outstanding principal and accrued and unpaid interest under
the Tranche B Loans and all accrued and unpaid interest under the Tranche A Loan
to the date of the closing of such acquisition shall be applied to reduce the
purchase price paid by Lender pursuant to such acquisition agreement at a rate
of $1.00 for every $1.00 of such outstanding principal and accrued and unpaid
interest under the Tranche B Loans and all accrued and unpaid interest under the
Tranche A Loan. Each $1.00 applied in the previous sentence to reduce the
purchase price paid by Lender shall be deemed a $1.00 repayment of the
Obligations and such Obligations shall be deemed cancelled to the extent of such
repayment.



                                      -3-

         2.7 Other Payment Terms

                  (a) Place and Manner. Borrower shall make all payments due to
Lender hereunder at the address specified in Section 7.1, in lawful money of the
United States and in same day or immediately available funds.

                  (b) Date. Whenever any payment due hereunder shall fall due on
a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall be included in the
computation of interest or fees, as the case may be.

                  (c) Default Rate. From and after the occurrence of an Event of
Default and during the continuance thereof, Borrower shall pay interest on the
aggregate, outstanding balance of the Loans, and on interest (compounded
annually) and other amounts not paid when due hereunder or under the other Loan
Documents, from the date due thereof until those amounts are paid in full at a
per annum rate (the "Default Rate") equal to the lesser of (i) a rate equal to
five percentage points in excess of the rate otherwise applicable to the Loans
at such time or (ii) the maximum rate permitted by law, such rate to change from
time to time as the rate otherwise applicable to the Loans shall change. All
computations of such interest shall be based on a year of twelve thirty (30) day
months for the actual number of days elapsed.

         2.8 Notes. The obligation of Borrower to repay the Tranche A Loan and
to pay interest thereon at the rates provided herein shall be evidenced by a
convertible promissory note in the form of Exhibit A (the "Tranche A Note"). The
obligation of Borrower to repay the Tranche B Loans and to pay interest thereon
at the rates provided herein shall be evidenced by a promissory note in the form
of Exhibit B (the "Tranche B Note" and together with the Tranche A Note, the
"Notes" and each a "Note"). With respect to Tranche B Loans, Borrower
irrevocably authorizes Lender to make or cause to be made, an appropriate
notation on Lender's Record reflecting the making of such Tranche B Loan or (as
the case may be) the receipt of a payment or prepayment of such Tranche B Loan.
The outstanding amount of the Tranche B Loans set forth on such Lender's Record
shall be prima facie evidence (absent manifest error) of the principal amount
thereof owing and unpaid to such Lender, but the failure to record, or any error
in so recording, any such amount on such Lender's Record shall not limit or
otherwise affect the obligations of the Borrower hereunder or under the Tranche
B Note to make payments of principal of or interest on the Tranche B Note when
due.

         2.9 Security; Further Assurances

                  (a) Security. The Obligations shall be secured by a Security
Agreement in the form of Exhibit C (the "Security Agreement").

                  (b) Further Assurances. Borrower shall deliver to Lender the
Security Agreement and such other instruments, agreements, certificates and
documents as Lender may reasonably request to create, perfect, evidence and
maintain (i) a first priority security interest of Lender in all of the assets
of Borrower as further set forth in the Security Agreement, subject only to
Permitted Liens and (ii) the rights of Lender under this Loan Agreement and the
other Loan Documents. Borrower shall fully cooperate with Lender and perform all
additional acts reasonably requested by Lender to effect the purposes of the
foregoing and the rights granted to Lender hereunder.



                                      -4-


ARTICLE 3. REPRESENTATIONS AND WARRANTIES OF BORROWER.

         To induce Lender to enter into this Loan Agreement and to make Loans
hereunder, Borrower represents and warrants to Lender that, except as set forth
on the disclosure schedule attached hereto as Schedule IV (the "Disclosure
Schedule"):

         3.1 Due Incorporation, Qualification, etc. Each of Borrower and its
Subsidiaries (i) is a corporation duly organized, validly existing and in good
standing under the laws of its state of incorporation; (ii) has the power and
authority to own, lease and operate its properties and carry on its business as
now conducted; and (iii) is duly qualified, licensed to do business and in good
standing as a foreign corporation in each jurisdiction where the failure to be
so qualified or licensed could reasonably be expected to have a Material Adverse
Effect.

         3.2 Authority. The execution, delivery and performance by Borrower of
each Loan Document to be executed by Borrower and the consummation of the
transactions contemplated thereby (i) are within the power of Borrower and (ii)
have been duly authorized by all necessary actions on the part of Borrower.

         3.3 Enforceability. Each Loan Document executed, or to be executed, by
Borrower has been, or will be, duly executed and delivered by Borrower and
constitutes, or will constitute, a legal, valid and binding obligation of
Borrower, enforceable against Borrower in accordance with its terms, except as
limited by bankruptcy, insolvency or other laws of general application relating
to or affecting the enforcement of creditors' rights generally and general
principles of equity.

         3.4 Non-Contravention. The execution and delivery by Borrower of the
Loan Documents executed by Borrower and the performance and consummation of the
transactions contemplated thereby do not and will not (i) violate any material
Requirement of Law applicable to Borrower; (ii) violate any provision of, or
result in the breach or the acceleration of, or entitle any other Person to
accelerate (whether after the giving of notice or lapse of time or both), any
material Contractual Obligation of Borrower; or (iii) result in the creation or
imposition of any Lien upon any property, asset or revenue of Borrower (except
such Liens as may be created in favor of Lender pursuant to this Loan Agreement
or the other Loan Documents).

         3.5 Approvals. No consent, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Authority or other
Person (including, without limitation, the shareholders of any Person) is
required in connection with the execution and delivery of the Loan Documents
executed by Borrower and the performance and consummation of the transactions
contemplated thereby, other than filings that may be required under applicable
federal and state securities laws and filings necessary to perfect the Lender's
security interest in the Collateral (as defined in the Security Agreement).

         3.6 No Violation or Default. None of Borrower or Borrower's
Subsidiaries is in violation of or in default with respect to (i) any material
Requirement of Law; (ii) any material Contractual Obligation (nor is there any
waiver in effect which, if not in effect, would result in such a violation or
default), where, in each case, such violation or default, individually, or
together with all such violations or defaults, could reasonably be expected to
have a Material Adverse Effect. Without limiting the generality of the
foregoing, to the best knowledge of Borrower, none of Borrower or Borrower's
Subsidiaries (A) has violated any Environmental Laws, (B) has any liability
under any Environmental Laws or (C) has received notice or other communication
of an investigation or is under investigation by any Governmental Authority
having authority to enforce Environmental Laws, where such violation, liability
or investigation could reasonably be expected to have a Material Adverse Effect.
No Event of Default or Default has occurred and is continuing. Except as set
forth



                                      -5-


(with estimates of the dollar amounts involved) in the Disclosure Schedule, no
actions (including, without limitation, derivative actions), suits, proceedings
or investigations are pending or, to the knowledge of Borrower, threatened
against Borrower at law or in equity in any court or before any other
governmental authority or (ii) seeks to enjoin, either directly or indirectly,
the execution, delivery or performance by Borrower of the Loan Documents or the
transactions contemplated thereby. The executed Memorandum of Understanding (the
"MOU") dated October 3, 2002, regarding a settlement of the certain outstanding
shareholder class action litigation involving Borrower referred to therein,
though it remains subject to court approval, has been entered into by Borrower
and all other necessary parties and is in full force and effect in accordance
with its terms.

         3.7 Title. Borrower and Borrower's Subsidiaries own and have good and
marketable title in fee simple absolute to, or a valid leasehold interest in,
all their respective real properties and good title to their other respective
assets and properties as reflected in the most recent Financial Statements
delivered to Lender (except those assets and properties disposed of in the
ordinary course of business since the date of such Financial Statements) and all
respective assets and properties acquired by Borrower and Borrower's
Subsidiaries since such date (except those disposed of in the ordinary course of
business). Such assets and properties are subject to no Lien, except for
Permitted Liens.

         3.8 No Agreements to Sell Assets. None of Borrower or Borrower's
Subsidiaries has any legal obligation, absolute or contingent, to any Person to
sell a material portion of the assets of Borrower or Borrower's Subsidiaries
(other than sales in the ordinary course of business), or to effect any merger,
consolidation or other reorganization of Borrower or to enter into any agreement
with respect thereto, except those transactions contemplated with Lender.

         3.9 Other Regulations. None of Borrower or its Subsidiaries is subject
to regulation under the Investment Company Act of 1940, the Public Utility
Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act,
any state public utilities code or to any federal or state statute or regulation
limiting its ability to incur Indebtedness.

         3.10 Governmental Charges and Other Indebtedness. Each of Borrower and
its Subsidiaries has filed or caused to be filed all tax returns (including
extensions thereof) which are required to be filed by it. Borrower and
Borrower's Subsidiaries have paid, or made provision for the payment of, all
taxes and other Governmental Charges which have or may have become due pursuant
to said returns or otherwise and all other Indebtedness, except such
Governmental Charges or Indebtedness, if any, which are being contested in good
faith and as to which adequate reserves (determined in accordance with GAAP)
have been provided or which could not reasonably be expected to have a Material
Adverse Effect if unpaid.

         3.11 Solvency, Etc. As of the Closing Date, Borrower is Solvent and,
after the execution and delivery of the Loan Documents and the consummation of
the transactions contemplated thereby will be Solvent.

         3.12 No Material Adverse Effect. As of the Closing Date, since June 30,
2002, no event has occurred and no condition exists which could reasonably be
expected to have a Material Adverse Effect, except as disclosed in Borrower's
Draft No. 8 of its Annual Report on Form 10-K for its fiscal year ended June 30,
2002, a copy of which, dated October 4, 2002, has been previously provided to
Lender.

         3.13 Accuracy of Information Furnished. No representation or warranty
or other statement of Borrower in any written certificates, statements or

occurrence and during the continuance of an Event of Default. Borrower shall
make all payments hereunder to Lender as indicated in the Loan Agreement, in
lawful money of the United States and in same day or immediately available
funds. Capitalized terms used and not otherwise defined herein, shall have the
respective meanings given to those terms in the Loan Agreement, dated as of

between Vari-L Company, Inc. and Sirenza Microdevices, Inc. This Note is the
Tranche A Note referred to in the Loan Agreement. This Note is subject to the
terms of the Loan Agreement, including the rights of prepayment and the rights
of acceleration of maturity.

         1. Payments. All outstanding principal and all accrued interest thereon
shall be due and payable on the Maturity Date.

         2. Prepayments. This Note shall be subject to the prepayment provisions
(both optional prepayment and mandatory prepayment) set forth in Section 2.5 of
the Loan Agreement.

         3. Security. THE OBLIGATIONS DUE UNDER THIS NOTE ARE SECURED BY A
SECURITY AGREEMENT DATED AS OF THE DATE HEREOF AND EXECUTED BY BORROWER IN FAVOR
OF LENDER. ADDITIONAL RIGHTS OF Lender ARE SET FORTH IN SUCH security AGREEMENT.

         4. Conversion.

                  (a) At Lender's sole option, Lender may convert the
outstanding principal amount due under this Note into the number of shares of
fully paid and nonassessable Common Stock as is determined pursuant to Section
4(b) below, at any time after the earliest to occur of the following:

                           (i) the fifth Business Day prior to Maturity of this
Note;





                           (ii) upon receipt of Borrower's written notice of
Borrower's election to prepay this Note pursuant to Section 2.5(a) of the Loan
Agreement;

                           (iii) upon the date of the commencement of a tender
offer by a Person (other than Lender) to purchase the Common Stock of Borrower
for cash or other assets, including, but not limited to securities of the
acquiring Person; and

                           (iv) the date of execution of a definitive
acquisition agreement with a Person other than Lender that will result in a
Change of Control.

                  (b) The outstanding principal amount due under this Note shall
be convertible into the number of shares of fully paid and nonassessable Common
Stock that constitutes 19.9% of the fully diluted outstanding Common Stock as of
the date of conversion. For purposes of the preceding sentence, the "fully
diluted outstanding Common Stock" shall be determined immediately prior to the
conversion of this Note (except as noted in subsection (iv) below) and shall be
deemed to include:

                           (i) the number of shares of Common Stock actually
outstanding; plus

                           (ii) the number of shares of Common Stock deliverable
upon exercise or conversion of options to purchase or rights to subscribe for
Common Stock; plus

                           (iii) the number of shares of Common Stock
deliverable upon conversion of or in exchange for convertible or exchangeable
securities (other than this Note), or upon exercise of options to purchase or
rights to subscribe for such convertible or exchangeable securities and
subsequent conversion or exchange thereof; plus

                           (iv) the number of shares of Common Stock issuable
pursuant to any memorandum of understanding, settlement agreement or court order
regarding any shareholder class action litigation involving Borrower (giving
full effect to any antidilution adjustments thereto, whether resulting from the
conversion of this Note or otherwise).

         In the event that Borrower declares a record date for a distribution of
Equity Securities to its shareholders prior to the date of conversion which
distribution will occur after the date of conversion, then such Equity
Securities shall be deemed outstanding and included on a Common Stock equivalent
basis in the calculation of Borrower's "fully diluted outstanding Common Stock."

                  (c) If Lender elects to convert the outstanding principal
amount of this Note into Common Stock, then Lender shall:

                           (i) deliver to Borrower at Borrower's address set
forth in Section 7.1 of the Loan Agreement a Conversion Notice in the form
attached hereto as Exhibit A; and

                           (ii) surrender this Note to Borrower, duly endorsed
or assigned to Borrower or in blank, at Borrower's address set forth in Section
7.1 of the Loan Agreement, on or prior to the close of business on the date of
conversion; provided that any failure by Lender to



                                      -2-


surrender this Note as provided herein shall not invalidate the conversion or
the effective date thereof.

         Borrower shall deliver to the Lender not more than three (3) Business
Days' after delivery by Lender of this Note to Borrower the certificates
representing shares of Common Stock issuable upon conversion of this Note. No
fractions of shares or scrip representing fractions of shares will be issued on
conversion, but instead of any fractional interest, Borrower shall round down to
the next higher whole share.

         Upon the date of conversion, Borrower shall pay to Lender all accrued
interest to the date of conversion with respect to this Note.

                  (d) Borrower shall at all times reserve and keep available,
free from preemptive rights, out of its authorized but unissued Common Stock,
for the purpose of effecting the conversion of this Note, the full number of
shares of Common Stock then issuable upon the conversion of this Note.

                  (e) Except as provided in the next sentence, Borrower will pay
any and all taxes and duties that may be payable in respect of the issue or
delivery of Common Stock on conversion of this Note. Borrower shall not,
however, be required to pay any tax or duty which may be payable in respect of
any transfer involved in the issue and delivery of Common Stock in a name other
than that of the holder of this Note, and no such issue or delivery shall be
made unless and until the Person requesting such issue has paid to Borrower the
amount of any such tax or duty, or has established to the satisfaction of
Borrower that such tax or duty has been paid.

                  (f) Borrower agrees that all Common Stock which may be
delivered upon conversion of this Note, upon such delivery, will have been duly
authorized and validly issued and will be fully paid and nonassessable and free

this Note have not been registered under the Securities Act, or the securities
laws of any state or other jurisdiction. Neither this Note nor the Common Stock
issuable upon conversion of this Note nor any interest or participation herein

exempt from, or not subject to the registration requirements of the Securities
Act.

                  (c) Lender by acceptance of this Note, represents that it is
an "accredited investor" within the meaning of Rule 501 of the Securities Act.
Lender by acceptance of this Note, acknowledges that it has been advised that
this Note has not been registered under the Securities Act, or any state
securities laws and, therefore, cannot be resold unless it is registered under
the Securities Act and applicable state securities laws or unless an exemption
from such registration requirements is available. Lender



                                      -4-


by acceptance of this Note, acknowledges that it is aware that Borrower is under
no obligation to effect any such registration or to file for or comply with any
exemption from registration (other than Borrower's obligations under the
Registration Rights Agreement). Lender by acceptance of this Note, represents
that it has not been formed solely for the purpose of making this investment and
is acquiring this Note for its own account for investment, and not with a view
to, or for resale in connection with, the distribution thereof. Lender by

in financial and business matters that Lender is capable of evaluating the
merits and risks of such investment, is able to incur a complete loss of such
investment and is able to bear the economic risk of such investment for an
indefinite period of time.

                  (e) If Borrower shall have paid any interest on this Note in
excess of that permitted by law, then it is the express intent of Borrower and
Lender that all excess amounts previously collected by Borrower be applied to
reduce the principal balance of this Note, and the provisions hereof immediately
be deemed reformed and the amounts thereafter collectable as interest hereunder
be reduced, without the necessity of the execution of any new document, so as to
comply with the then applicable law, but so as to permit the recovery of the
fullest amount otherwise called for hereunder.

                  (f) Neither Borrower nor Lender shall Transfer this Note or
delegate any of their respective obligations or rights hereunder without the
prior written consent of the non-assigning party, except that Lender may assign

obligations under this Note in connection with the merger or consolidation of
Lender with or into another Person.
