                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of April
28, 2004, is by and among Verilink Corporation, a Delaware corporation
("Verilink"), SRI Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Verilink (the "Merger Sub"), and Larscom Incorporated, a Delaware
corporation ("Larscom") (Larscom, taken together as one party, and Verilink and
Merger Sub, taken together as the other party, are sometimes referred to herein
as a "party" and collectively as the "parties").

         WHEREAS, the board of directors of Larscom (the "Larscom Board") and
the board of directors of Verilink (the "Verilink Board") each deems it
advisable and in the best interests of its corporation and its stockholders that
Verilink acquire Larscom, by means of a merger of Merger Sub with and into
Larscom with Larscom surviving as a wholly owned subsidiary of Verilink (the
"Merger") in accordance with the terms of this Agreement and the General
Corporation Law of the State of Delaware (the "DGCL");

         WHEREAS, concurrently with the execution and delivery of this Agreement
and as a condition and inducement to Verilink's willingness to enter into this
Agreement, the majority stockholders of Larscom will be entering into the
Larscom Voting Agreement, dated as of the date of this Agreement, in the form
attached hereto as Exhibit A (the "Larscom Voting Agreement"), pursuant to which
each such stockholder will, among other things, agree to give Verilink a proxy
to vote all of the shares of capital stock of Larscom that such stockholder
owns, subject to certain restrictions, in order to consummate the transactions
contemplated hereby;

         WHEREAS, concurrently with the execution and delivery of this Agreement
and as a condition and inducement to Larscom's willingness to enter into this
Agreement, certain stockholders of Verilink will be entering into the Verilink
Voting Agreement, dated as of the date of this Agreement, in the form attached
hereto as Exhibit B (the "Verilink Voting Agreement"), pursuant to which each
such stockholder will, among other things, agree to give Larscom a proxy to vote
all of the shares of capital stock of Verilink that such stockholder owns in
order to consummate the transactions contemplated hereby;

         WHEREAS, for United States federal income tax purposes, it is intended
that the Merger shall qualify as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and the
rules and regulations promulgated thereunder, and that each of Verilink, the
Merger Sub and Larscom are a party to a reorganization within the meaning of
Section 368(a) of the Code;

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, Verilink,
the Merger Sub and Larscom agree as follows:



                                   ARTICLE I

                                   THE MERGER

         1.1      The Merger.

                  Upon and subject to the terms and conditions of this
Agreement, the Merger Sub shall merge with and into Larscom at the Effective
Time. From and after the Effective Time, the separate corporate existence of the
Merger Sub shall cease, and Larscom shall continue as the surviving corporation
in the Merger. Larscom following the Merger is sometimes referred to herein as
the "Surviving Corporation." The Merger shall be effected by filing a
certificate of merger (the "Certificate of Merger") in a form mutually
acceptable to Verilink and Larscom and executed by the Surviving Corporation in
accordance with Section 251(c) of the DGCL. The Merger shall have the effects
set forth in Section 259 of the DGCL.

         1.2      The Closing.

                  (a) Unless this Agreement is earlier terminated pursuant to
Article VIII, the closing of the Merger (the "Closing") shall take place at 9:00
a.m., eastern time, on a date to be specified by Larscom and Verilink (the
"Closing Date"), which shall be no later than the second business day after
satisfaction or waiver of the conditions set forth in Article VII (other than
delivery of items to be delivered at the Closing and other than satisfaction of
those conditions that by their nature are to be satisfied at the Closing, it
being understood that the occurrence of the Closing shall remain subject to the
delivery of such items and the satisfaction or waiver of such conditions at the
Closing), at the offices of Powell, Goldstein, Frazer & Murphy LLP, 191
Peachtree Street, Atlanta, Georgia 30303, unless another date, place or time is
agreed to in writing by Larscom and Verilink.

                  (b) At the Closing:

                           (i) Verilink shall deliver to Larscom the various
                  certificates, instruments and documents referred to in Section
                  7.2;

                           (ii) Larscom shall deliver to Verilink the various
                  certificates, instruments and documents referred to in Section
                  7.3; and

                           (iii) Larscom, on behalf of the Surviving
                  Corporation, shall file the Certificate of Merger with the
                  Secretary of State of the State of Delaware.

         1.3      Effective Time.

                  Subject to the provisions of this Agreement, the parties shall
cause the Merger contemplated by this Agreement to be consummated by the filing
of the Certificate of Merger with the Secretary of State of the State of
Delaware. The Merger shall become effective at such time as the Certificate of
Merger has been duly filed with the Secretary of State of the State of Delaware,
or at such subsequent date or time as the parties shall mutually agree upon (the
time the Merger becomes effective referred to herein as the "Effective Time").

                                       2


         1.4      Certificate of Incorporation and Bylaws of the Surviving
                  Corporation.

                  (a) The Certificate of Incorporation of Larscom shall be
amended and restated, by means of the Certificate of Merger, to substantially
conform to the Certificate of Incorporation of the Merger Sub as in effect
immediately prior to the Effective Time (except that the name of the Surviving
Corporation shall be "Larscom" or such other name as is mutually agreed to by
Verilink and Larscom) and, as so amended, such Certificate of Incorporation
shall be the Certificate of Incorporation of the Surviving Corporation, until
further amended in accordance with the DGCL and such Certificate of
Incorporation.

                  (b) As of the Effective Time, by virtue of the Merger and
without any action on the part of the Merger Sub and Verilink, the Bylaws of the
Surviving Corporation shall be amended and restated to read the same as the
Bylaws of Merger Sub, as in effect immediately prior to the Effective Time,
until thereafter amended in accordance with the DGCL, the Certificate of
Incorporation of the Surviving Corporation and such Bylaws.

         1.5      Directors and Officers of the Surviving Corporation.

                  (a) The directors of the Merger Sub immediately prior to the
Effective Time shall be the initial directors of the Surviving Corporation, each
to hold office in accordance with the Certificate of Incorporation and Bylaws of
the Surviving Corporation.

                  (b) The officers of the Merger Sub immediately prior to the
Effective Time shall be the initial officers of the Surviving Corporation, each
to hold office in accordance with the Certificate of Incorporation and Bylaws of
the Surviving Corporation.

         1.6      Directors of Verilink.

                  Prior to the Effective Time, Verilink shall take all necessary
action to cause the number of directors constituting the full Verilink Board to
be increased by one director as of the Effective Time and to cause Desmond P.
Wilson III to be appointed to the Verilink Board to fill such vacancy.

         1.7      Tax Consequences.

  The parties hereto intend that the Merger shall constitute a reorganization
within the meaning of Section 368(a) of the Code. The parties hereto adopt this
Agreement as a "plan of reorganization" within the meaning of Section 1.368-3(a)
of the U.S. Income Tax Regulations.

                                   ARTICLE II

                            CONVERSION OF SECURITIES

         2.1      Conversion of Capital Stock.

  As of the Effective Time, by virtue of the Merger and without any action on
the part of the Merger Sub, Larscom or the holder of any shares of the capital
stock of Larscom or the Merger

                                       3


Sub:

                  (a) Capital Stock of the Merger Sub. Each share of the common
stock of the Merger Sub issued and outstanding immediately prior to the
Effective Time shall be converted into and become one fully paid and
nonassessable share of common stock, $0.01 par value per share, of the Surviving
Corporation. From and after the Effective Time, all certificates representing
the common stock of the Merger Sub shall be deemed for all purposes to represent
the number of shares of common stock of the Surviving Corporation into which
they were converted in accordance with this Section 2.1(a).

                  (b) Exchange Ratio for Larscom Common Stock. Subject to this
Section 2.1 and Section 2.2 hereof, each share of common stock of Larscom, $0.01
par value (the "Larscom Common Stock") issued and outstanding immediately prior
to the Effective Time, other than shares to be cancelled in accordance with
Section 2.1(c) hereof, shall be automatically converted into the right to
receive the number of validly issued, fully paid and nonassessable shares of
Common Stock, $0.01 par value per share, of Verilink ("Verilink Common Stock")
equal to 1.166 multiplied by the Adjustment Factor as defined in Section 2.4
(the "Exchange Ratio"). As of the Effective Time, all such shares of Larscom
Common Stock shall no longer be outstanding and shall automatically be cancelled
and retired and shall cease to exist, and each holder of a certificate
representing any such shares of Larscom Common Stock shall cease to have any
rights with respect thereto, except the right to receive the Verilink Common
Stock pursuant to this Section 2.1(b) and any cash in lieu of fractional shares
of Verilink Common Stock to be issued or paid in consideration therefor upon the
surrender of such certificate in accordance with Section 2.2, without interest.

                  (c) Cancellation of Treasury Stock and Verilink-Owned Stock.
All shares of Larscom Common Stock that are owned by Larscom as treasury stock
and any shares of Larscom Common Stock owned by Verilink or the Merger Sub
immediately prior to the Effective Time shall be cancelled and shall cease to
exist and no shares of Verilink or other consideration shall be delivered in
exchange therefor.

                  (d) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect fully the effect of any reclassification, share or stock
split, reverse split, share or stock dividend (including any dividend or
distribution of securities convertible into Verilink Common Stock or Larscom
Common Stock), reorganization, recapitalization or other like change with
respect to Verilink Common Stock or Larscom Common Stock occurring (or for which
a record date is established) after the date hereof and prior to the Effective
Time.

                  (e) Unvested Stock. If any shares of Larscom Common Stock
outstanding immediately prior to the Effective Time are unvested or are subject
to a repurchase option, risk of forfeiture or other condition under any
applicable restricted stock purchase agreement or other agreement with Larscom,
then the shares of Verilink Common Stock issued in exchange for such shares of
Larscom Common Stock will also be unvested or subject to the same repurchase
option, risk of forfeiture or other condition, and the certificates representing
such shares of Verilink Common Stock will accordingly be marked with appropriate
legends. All outstanding rights which Larscom may hold immediately prior to the
Effective Time to repurchase unvested shares of Larscom Common Stock or to
exercise any other right with respect to shares of

                                       4


Larscom Common Stock that are restricted shall be automatically assigned to
Verilink in the Merger at the Effective Time and shall thereafter be exercisable
by Verilink upon the same terms and conditions (including, without limitation,
any provision for acceleration) in effect immediately prior to the Effective
Time, except that the shares purchasable pursuant to such rights and the
purchase price payable per share shall be appropriately adjusted to reflect the
Exchange Ratio. Larscom shall take all reasonable steps necessary to cause the
foregoing provisions of this Section 2.1(e) to occur.

         2.2      Exchange of Certificates.

  The procedures for exchanging outstanding shares of Larscom Common Stock for
Verilink Common Stock pursuant to the Merger are as follows:

                  (a) Exchange Agent.

  At or promptly following the Effective Time, Verilink shall deposit, or cause
to be deposited, with Verilink's transfer agent or another bank or trust company
designated by Verilink and reasonably acceptable to Larscom (the "Exchange
Agent"), for the benefit of the holders of shares of Larscom Common Stock, for
exchange, in accordance with this Section 2.2: (i) Verilink Common Stock
issuable pursuant to Section 2.1 in exchange for outstanding shares of Larscom
Common Stock, (ii) cash in an amount sufficient to make payments for fractional
shares required pursuant to Section 2.2(c), and (iii) any dividends or
distributions to which holders of certificates which immediately prior to the
Effective Time represented outstanding shares of Larscom Common Stock (the
"Certificates") may be entitled pursuant to Section 2.2(d) (such Verilink Common
Stock, together with the amount of any dividends or other distributions payable
with respect thereto and any cash in lieu of fractional shares, being
collectively hereinafter referred to as the "Exchange Fund").

                  (b) Exchange Procedures.

  Promptly following the Effective Time, the Exchange Agent shall mail to each
holder of record of a Certificate or Certificates whose shares were converted
pursuant to Section 2.1 into the right to receive shares of Verilink Common
Stock (i) a letter of transmittal in customary form, reasonably satisfactory to
Larscom (which shall specify that delivery shall be effected, and risk of loss
and title to the Certificates shall pass, only upon delivery of the Certificates
to the Exchange Agent, and shall contain such other provisions as Verilink may
reasonably require) and (ii) instructions for effecting the surrender of the
Certificates in exchange for Verilink Common Stock (plus cash in lieu of
fractional shares of Verilink Common Stock, if any, and any dividends or
distributions as provided below). Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Verilink, together with such letter of transmittal, duly executed,
and such other documents as may reasonably be required by the Exchange Agent,
the holder of such Certificate shall be entitled to receive in exchange therefor
a certificate representing that number of whole shares of Verilink Common Stock
which such holder has the right to receive pursuant to the provisions of Section
2.1 plus cash in lieu of fractional shares pursuant to Section 2.2(c) and any
dividends or distributions pursuant to Section 2.2(d), and the Certificate so
surrendered shall immediately be cancelled. In the event of a valid transfer of
ownership of Larscom Common Stock which is not registered in

                                       5


the transfer records of Larscom, a certificate representing the proper number of
shares of Verilink Common Stock plus cash in lieu of fractional shares pursuant
to Section 2.2(c) and any dividends or distributions pursuant to Section 2.2(d)
may be issued or paid to a person other than the person in whose name the
Certificate so surrendered is registered, if such Certificate is presented to
the Exchange Agent, accompanied by all documents reasonably required to evidence
and effect such transfer and by evidence that any applicable stock transfer
taxes have been paid or are not payable. Until surrendered as contemplated by
this Section 2.2, each Certificate shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
Verilink Common Stock issued in consideration therefor plus cash in lieu of
fractional shares pursuant to Section 2.2(c) and any dividends or distributions
pursuant to Section 2.2(d) as contemplated by this Section 2.2.

                  (c) No Fractional Shares.

  No fraction of a share of Verilink Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests
shall not entitle the owner thereof to vote or to any other rights of a
stockholder of Verilink. Notwithstanding any other provision of this Agreement,
each holder of shares of Verilink Common Stock converted pursuant to the Merger
who would otherwise have been entitled to receive a fraction of a share of
Verilink Common Stock (after taking into account all Certificates delivered by
such holder and the aggregate number of shares of Larscom Common Stock
represented thereby) shall receive, in lieu thereof, cash (without interest) in
an amount equal to such fractional part of a share of Verilink Common Stock
multiplied by the last reported sale price of a share of Verilink Common Stock
at the 4:00 p.m. Eastern time, end of regular trading hours on The Nasdaq Stock
Market, on the last trading day prior to the Effective Time (or if the Verilink
Common Stock shall not be traded on The Nasdaq Stock Market at such time, the
last reported sale price on such day as reported on the OTC Bulletin Board, if
so reported, or the average of the high and low bid prices in the
over-the-counter market on such day if not so reported).

                  (d) Distributions with Respect to Unexchanged Shares.

  No dividends or other distributions declared or made after the Effective Time
with respect to Verilink Common Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered Certificate until the
holder of record of such Certificate shall surrender such Certificate. Subject
to the effect of applicable laws, promptly following surrender of any such
Certificate, the Exchange Agent shall deliver to the record holder thereof,
without interest, (i) the amount of dividends or other distributions with a
record date after the Effective Time previously paid with respect to such whole
shares of Verilink Common Stock, and (ii) at the appropriate payment date, the
amount of dividends or other distributions payable with respect to such whole
shares of Verilink Common Stock having a record date after the Effective Time
but prior to the date of such surrender and a payment date subsequent to the
date of such surrender.

                  (e) No Further Ownership Rights in Verilink Common Stock. All
shares of Verilink Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms hereof (including any cash or
dividends or other distributions paid pursuant to Section 2.2(c) or 2.2(d))
shall be deemed to have been issued (and paid) in full satisfaction of all
rights pertaining to such shares of Larscom Common Stock, and from and after the
Effective

                                       6


Time there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of Larscom Common Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation or the
Exchange Agent for any reason, they shall be cancelled and exchanged for the
consideration provided for, and in accordance with the procedures set forth, in
this Article II.

                  (f) Termination of Exchange Fund/Limitation of Liability. Any
portion of the Exchange Fund (including the proceeds of any investments thereof
and any Verilink Common Stock) that remains unclaimed by the stockholders of
Larscom for six (6) months after the Effective Time shall be paid to Verilink.
Any stockholders of Larscom who have not theretofore complied with this Article
II shall thereafter look only to Verilink for payment of their shares of
Verilink Common Stock and any cash, dividends and other distributions in respect
of Verilink Common Stock payable and/or issuable pursuant to Section 2.1, 2.2(c)
and 2.2(d) upon due surrender of the Certificates (or affidavits of loss in lieu
thereof and, if required, the posting of a bond), in each case, without any
interest thereon. To the extent permitted by applicable law, none of Verilink,
the Merger Sub, Larscom, the Surviving Corporation or the Exchange Agent shall
be liable to any holder of shares of Verilink Common Stock or Larscom Common
Stock, as the case may be, for such shares (or dividends or distributions with
respect thereto) delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

                  (g) Withholding Rights. Each of the Exchange Agent, Verilink
and the Surviving Corporation shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Article II to any holder of
shares of Larscom Common Stock such amounts as it reasonably determines that it
is required to deduct and withhold with respect to the making of such payment
under the Code, or any other applicable provision of state, local or foreign tax
law or any other applicable legal requirement. To the extent that amounts are so
deducted or withheld by the Exchange Agent, the Surviving Corporation or
Verilink, as the case may be, such deducted or withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Larscom Common Stock in respect of which such deduction and
withholding was made by the Exchange Agent, the Surviving Corporation or
Verilink, as the case may be.

                  (h) Lost Certificates. In the event that any Certificate shall
have been lost, stolen or destroyed, the Exchange Agent may require the
stockholder of such lost, stolen or destroyed Certificate, in exchange for such
lost, stolen or destroyed Certificate, to make and deliver an affidavit of that
fact and provide such other documentation and pay such fees, or post such bonds,
as is the customary practice of the Exchange Agent to require, prior to
delivering the certificates representing the shares of Verilink Common Stock
into which the shares of Larscom Common Stock represented by such lost, stolen
or destroyed Certificate was converted pursuant to Section 2.1 and cash for
fractional shares, if any, as may be required pursuant to Section 2.2(c) and any
dividends or distributions payable pursuant to Section 2.2(d), in each case
without any interest thereon; provided, however, that Verilink may, in its
discretion and as a condition precedent to the issuance of such certificates
representing shares of Verilink Common Stock and other distributions, require
the owner of such lost, stolen or destroyed Certificate to deliver a bond in
such sum as it may reasonably direct as indemnity against any claim that may be
made against Verilink, the Surviving Corporation, or the Exchange Agent with
respect to the

                                       7


Certificates alleged to have been lost, stolen or destroyed; provided, further,
that in no event shall Verilink be required to pay any fee or post any bond
referred to in this Section 2.2(h).

         2.3      Larscom Stock Plans and Larscom Warrants.

                  (a) At the Effective Time, each outstanding option to purchase
Larscom Common Stock under any of the Larscom Incorporated Stock Incentive Plan,
the Larscom Incorporated Stock Option Plan for Non-Employee Directors, the VINA
Technologies, Inc. 2000 Stock Incentive Plan, the VINA Technologies, Inc. 1998
Stock Plan, and the VINA Technologies, Inc. 1996 Stock Option/Stock Issuance
Plan (collectively, the "Larscom Stock Plans"), all of which shall be fully
vested and exercisable (each a "Larscom Stock Option") and each Larscom Warrant
shall be assumed by Verilink and shall thereafter be exercisable, on the same
terms and conditions as were applicable under such Larscom Stock Option (subject
to the applicable Larscom Stock Plan as administered by Verilink from and after
the Effective Time) or Larscom Warrant (in accordance with the past practices of
Larscom with respect to the interpretation and application of such terms and
conditions), as the case may be, prior to the Effective Time, except that (i)
each Larscom Stock Option and Larscom Warrant shall be exercisable for that
number of whole shares of Verilink Common Stock equal to the product obtained by
multiplying (x) the number of shares of Larscom Common Stock that were issuable
upon exercise of such Larscom Stock Option or Larscom Warrant immediately prior
to the Effective Time by (y) the Exchange Ratio, rounded, in the case of a
Larscom Warrant, up, and, in the case of any Larscom Stock Option, down, to the
nearest whole number of shares of Larscom Common Stock, and (ii) the per share
exercise price for the shares of Larscom Common Stock issuable upon exercise of
such assumed Larscom Stock Option or Larscom Warrant shall be equal to the
quotient determined by dividing (x) the exercise price per share of Larscom
Common Stock at which such Larscom Stock Option or Larscom Warrant was
exercisable immediately prior to the Effective Time, by (y) the Exchange Ratio,
rounded up to the nearest whole cent.

                  (b) The parties intend that, to the extent that any Larscom
Stock Option constituted an incentive stock option immediately prior to the
Effective Time, such option continues to qualify as an incentive stock option to
the maximum extent permitted by Section 422 of the Code, and the assumption of
the Larscom Stock Option provided in Section 2.3(a) satisfy the conditions of
Section 424(a) of the Code. Holders of Larscom Stock Options or Larscom Warrants
will not be entitled to acquire shares of Larscom Common Stock after the Merger.
In addition, prior to the Effective Time, Larscom will make any amendments to
the terms of such Larscom Stock Plans or arrangements that are necessary to give
effect to the transactions contemplated by this Section 2.3.

                  (c) As soon as practicable after the Effective Time, Verilink
shall deliver to the participants in the Larscom Stock Plans and holders of
Larscom Warrants an appropriate notice evidencing the foregoing assumption of
such Larscom Stock Options or Larscom Warrants, as the case may be, and setting
forth such participants' rights in the Larscom Stock Options and Larscom
Warrants, as provided in this Section 2.3.

                  (d) Verilink shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Verilink Common Stock for
delivery upon exercise of Larscom

                                       8


Stock Options and Larscom Warrants assumed in accordance with this Section 2.3.
Within ten (10) business days after the Effective Time, Verilink shall file one
or more registration statements on Form S-8 (or any successor form) with respect
to the shares of Verilink Common Stock subject to such Larscom Stock Options (to
the extent a Form S-8 is available for such options) and shall maintain the
effectiveness of such registration statement or registrations statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such Larscom Stock Options remain outstanding.

                  (e) The rights of participants in the Larscom Incorporated
Stock Purchase Plan (the "Larscom ESPP") with respect to any offering then
underway under the Larscom ESPP shall be determined by treating the last
business day prior to the Effective Time as the last day of such offering and by
making such other pro rata adjustments as may be necessary to reflect the
shortened offering but otherwise treating such shortened offering as a fully
effective and completed offering for all purposes under the Larscom ESPP.
Outstanding rights to purchase shares of Larscom Common Stock shall be exercised
in accordance with the Larscom ESPP, and each share of Larscom Common Stock
purchased pursuant to such exercise shall by virtue of the Merger, and without
any action on the part of the holder thereof, be converted into the right to
receive a number of shares of Verilink Common Stock in accordance with Section
2.1(b) hereof without issuance of certificates representing issued and
outstanding shares of Larscom Common Stock to participants under the Larscom
ESPP. As of the Effective Time, the Larscom ESPP shall be terminated. Prior to
the Effective Time, Larscom shall (i) provide Verilink with evidence that the
Larscom ESPP has been terminated pursuant to resolutions of Larscom's Board, the
form and substance of such resolutions shall be subject to prior review and
approval of Verilink (the approval of which shall not be unreasonably withheld)
and (ii) take such other actions (including, but not limited to, if appropriate,
amending the Larscom ESPP) that are necessary to give effect to the transaction
contemplated by this Section 2.3(e).

         2.4      Adjustment Factor.

                  (a) The "Adjustment Factor" shall be equal to the quotient
obtained by dividing (i) the Closing Net Adjusted Working Capital Amount plus
$24,365,600 by (ii) the Targeted Net Adjusted Working Capital Amount plus
$24,365,600; provided, however, if the Closing Net Adjusted Working Capital
Amount is less than the Targeted Net Working Capital Amount by $100,000.00 or
less, or exceeds the Targeted Net Working Capital Amount, then, in either case,
the Adjustment Factor shall be equal to 1. The "Targeted Net Adjusted Working
Capital Amount" shall be:

                           (i) $5,500,000 if the Closing Date occurs on or
                  before July 9, 2004;

                           (ii) $5,000,000 if the Closing Date occurs on or
                  after July 10, 2004 and before August 15, 2004; or

                           (iii) $4,500,000 if the Closing Date occurs on or
                  after August 15, 2004.

                  (b) Larscom shall cause to be prepared and delivered to
Verilink a "Statement of Closing Net Adjusted Working Capital Amount," which
shall include Larscom's calculation of the Closing Net Adjusted Working Capital
Amount, as of the anticipated Closing Date, which

                                       9


date shall be two business days after the later to occur of the Verilink
Stockholders Meeting or the Larscom Stockholders Meeting or such other date as
may be mutually agreed upon by Verilink and Larscom (the "Adjustment Date").

                  Verilink shall have an opportunity to participate in Larscom's
preparation of the Statement of Closing Net Adjusted Working Capital Amount and
to review all records and workpapers related thereto. Larscom shall deliver the
Statement of Closing Net Adjusted Working Capital Amount no later than ten (10)
Business Days prior to the Adjustment Date (the "Delivery Date"). If Larscom and
Verilink are unable to agree on the Statement of Closing Net Adjusted Working
Capital Amount within ten (10) Business Days after the Delivery Date, then
Verilink and Larscom agree to retain an accounting firm selected by Verilink and
reasonably acceptable to Larscom (the "Accounting Firm") to read and analyze the
Statement of Closing Net Adjusted Working Capital Amount delivered by Larscom
for correctness and compliance with the calculation described in Section 2.4(c)
below within five (5) Business Days of the date of the delivery of Larscom's
Statement of Closing Net Adjusted Working Capital Amount (the "Review Period")
to the Accounting Firm. Both Verilink and Larscom agree to execute and deliver
such indemnity and other agreements related to the engagement of the Accounting
Firm as may be required by the Accounting Firm. Based upon the foregoing
procedures, the Accounting Firm shall have the right, in its sole discretion, to
modify the Statement of Closing Net Adjusted Working Capital Amount to ensure
that it complies with the calculation described in Section 2.4(c) below. The
Accounting's Firm's procedures and modifications, if any, of the Statement of
Closing Net Adjusted Working Capital Amount, if any, shall be binding on the
Parties. Both Larscom and Verilink shall have an opportunity to participate in
such analysis and comment on the workpapers related thereto prior to the
delivery of the final Statement of Closing Net Adjusted Working Capital Amount
by the Accounting Firm.

                  (c) For the purposes of this Section 2.4, the "Closing Net
Adjusted Working Capital Amount" shall be calculated as follows:

                           (i) Current Assets of Larscom (as defined under, and
                  calculated in accordance with, GAAP on a consistent basis with
                  the Larscom Balance Sheet), less

                           (ii) Current Liabilities of Larscom (as defined
                  under, and calculated in accordance with, GAAP on a consistent
                  basis with the Larscom Balance Sheet); provided, however, that
                  (A) up to $690,000 of Larscom's expenses associated with the
                  transactions contemplated by this Agreement (including,
                  without limitation, all legal, investment banking and other
                  professional fees and expenses and all printing, mailing and
                  transfer agent fees associated with the Joint Proxy
                  Statement/Prospectus delivered to Larscom's stockholders (such
                  printing and mailing fees calculated on a pro rata basis
                  between Larscom's total number of record and beneficial
                  stockholders as of the record date for the Larscom Meeting and
                  Verilink's total number of record and beneficial stockholders
                  as of the record date for the Verilink Meeting)), (B) employee
                  severance expenses relating to employees whose employment is
                  terminated immediately prior to or after the Closing, and (C)
                  expenses relating to retention bonuses payable to Larscom
                  employees, whether or not any of the expenses set forth in
                  clauses (A) through

                                       10


                  (C) have been paid or are payable on or after the Closing
                  Date, shall not be taken into account for any purpose to
                  decrease the Closing Net Adjusted Working Capital Amount.

         2.5      Taking Necessary and Further Action.

  If, at any time after the Effective Time, any further action is necessary or
desirable to carry out the purpose of this Agreement and to vest the Surviving
Corporation with the full right, title and possession to all assets, property,
rights, privileges, powers and franchises of Larscom and the Merger Sub, the
officers and directors of Larscom and the Merger Sub will take all such
reasonable, lawful and necessary action.

                                  ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF LARSCOM

         Larscom represents and warrants to Verilink and the Merger Sub that the
statements contained in this Article III are true and correct, except as
expressly set forth herein or in the disclosure schedule delivered by Larscom to
Verilink on the date of this Agreement which is made a part hereof (the "Larscom
Disclosure Schedule"). The Larscom Disclosure Schedule will be arranged in
paragraphs corresponding to the lettered and numbered paragraphs contained in
this Agreement.

         3.1      Organization, Standing and Power.

  Larscom is a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation, has all requisite
corporate power and authority to own, lease and operate its properties and
assets and to carry on its business as now being conducted and as presently
proposed to be conducted, and is duly qualified to do business and is in good
standing as a foreign corporation in each jurisdiction where the character of
the properties it owns, operates or leases or the nature of its activities makes
such qualification necessary, except for such failures to be so organized,
qualified or in good standing, individually or in the aggregate, which have not
had, and are not reasonably likely to have a Larscom Material Adverse Effect.
For purposes of this Agreement, the term "Larscom Material Adverse Effect" means
any material adverse change, event, circumstance or development with respect to,
or material adverse effect on, the business, assets, liabilities,
capitalization, condition (financial or other), or results of operations of
Larscom and its Subsidiaries, taken as a whole; provided, however, that none of
the following shall, in and of itself, be taken into account when determining
whether there has been, or will be, a Larscom Material Adverse Effect: (i) any
failure by Larscom to meet or exceed analysts' published revenues or analysts'
published earnings predictions or any change in Larscom's stock price or trading
volume; (ii) with respect to the use of the term "Larscom Material Adverse
Effect" in the representations and warranties contained in Section 3.8, any
effect resulting directly from the announcement or pendency of this Agreement or
the Merger; or (iii) any effect that results from changes affecting generally
the industry or industries in which Larscom or any of its Subsidiaries
participates, the U.S. economy as a whole or foreign economies in any locations
where Larscom or any of its Subsidiaries has material operations, or sales or
customers unless such condition shall disproportionately

                                       11


adversely affect Larscom or any of its Subsidiaries.

         3.2      Charter Documents.

  Larscom has previously furnished or made available to Verilink a complete and
correct copy of its (i) Certificate of Incorporation and Bylaws as amended to
date (together, the "Larscom Charter Documents") and (ii) each of its
Subsidiaries' Certificate of Incorporation, or equivalent organizational
documents, and Bylaws, or equivalent organizational documents. Such Larscom
Charter Documents and equivalent organizational documents of each of its
Subsidiaries are in full force and effect. Larscom is not in violation of any of
the provisions of the Larscom Charter Documents, and no Subsidiary of Larscom is
in violation of its equivalent organizational documents.

         3.3      Capitalization.

                  (a) The authorized capital stock of Larscom consists of
111,900,000 shares of Larscom Common Stock, $0.01 par value per share, of which
there were 5,100,255 shares issued and outstanding as of the close of business
on April 28, 2004, and 5,000,000 shares of preferred stock, $0.01 par value per
share ("Larscom Preferred Stock"), of which no shares are outstanding. As of the
close of business on April 28, 2004, (i) no shares of Larscom Common Stock were
held in the treasury for Larscom; (ii) 637,010 shares of Larscom Common Stock
were reserved for future issuance pursuant to the Larscom Incorporated Stock
Plans and 586,133 shares were subject to outstanding options; (iii) 44,836
shares of Larscom Common Stock were reserved for future issuance pursuant to the
Larscom ESPP and no shares were subject to outstanding purchase rights; and (iv)
269,319 shares of Larscom Common Stock were reserved for future issuance upon
the exercise of outstanding warrants (the "Larscom Warrants").

                  (b) Section 3.3(b) of the Larscom Disclosure Schedule lists
all issued and outstanding shares of Larscom Common Stock that constitute
restricted stock or that are otherwise subject to a repurchase or redemption
right or right of first refusal in favor of Larscom, indicating the name of the
applicable stockholder, the vesting schedule for any such shares, including the
extent to which any such repurchase or redemption right or right of first
refusal has lapsed as of the date of this Agreement, the price at which such
stock can be repurchased and redeemed and whether (and to what extent) the
vesting will be accelerated in any way by the Merger or by termination of
employment or change in position following consummation of the Merger.

                  (c) Section 3.3(c) of the Larscom Disclosure Schedule sets
forth a complete and accurate list, as of the date of this Agreement, of all
Larscom Stock Options, indicating with respect to each such Larscom Stock Option
the name of the holder thereof, the Larscom Stock Plan under which it was
granted, the number of shares of Larscom Common Stock subject to such Larscom
Stock Option, the exercise price, the date of grant and expiration, and the
vesting schedule, including the vesting commencement date and whether (and to
what extent) the vesting will be accelerated in any way by the Merger or by
termination of employment or change in position following consummation of the
Merger. All Larscom Stock Options have been granted under one of the Larscom
Stock Plans. Larscom has provided or made available to Verilink complete and
accurate copies of all Larscom Stock Plans and the forms of all stock option

                                       12


agreements evidencing Larscom Stock Options and Larscom Warrants. No
acceleration of vesting, exercise, or repurchase of any Larscom Stock Option or
Larscom Warrant will occur as a result of or in connection with the Merger or by
termination of employment or change in position following consummation of the
Merger. The exercise period of each Larscom Stock Option terminates within 90
days or less of the termination of the holder's employment or service to
Larscom.

                  (d) There are no equity securities or other similar ownership
interests of any class or series of capital stock of Larscom, or any securities
convertible into or exercisable or exchangeable for such equity securities or
other similar ownership interests issued, reserved for issuance or outstanding.
Except for securities Larscom owns, directly or indirectly through any of its
Subsidiaries, there are no equity securities, partnership interests or other
similar ownership interests of any class or series of capital stock of any
Subsidiary of Larscom, or any securities convertible into or exercisable or
exchangeable for such equity securities, partnership interests or other similar
ownership interests issued, reserved for issuance or outstanding. There are no
options, warrants, equity securities, partnership interests or other similar
ownership interests, calls, rights (including preemptive rights), commitments or

operated or leased or the nature of its activities makes such qualification
necessary, except for such failures to be so organized, qualified or in good
standing that, individually or in the aggregate, have not had, and are not
reasonably likely to have, a Larscom Material Adverse Effect. All of the
outstanding shares of capital stock and other equity securities or interests of
each Subsidiary of Larscom are duly authorized, validly issued, fully paid,

in any Subsidiary of Larscom or any other entity.

Larscom's stockholders under the DGCL and the rules of The Nasdaq Stock Market,
Inc. and applicable law (the "Larscom Stockholder Approval"), to perform its
obligations hereunder and to consummate the transactions contemplated by this

                  (b) The execution and delivery of this Agreement by Larscom do

material benefit) under, or require a consent or waiver under, constitute a
change in control under, require the payment of a penalty under or result in the
imposition of any mortgages, security interests, pledges, liens, charges or

secret.

                  (e) Larscom and its Subsidiaries exclusively own all right,
title, and interest to and in the Larscom Intellectual Property free and clear
of all Liens (other than non-exclusive licenses under the Larscom Intellectual
Property granted by Larscom, its Subsidiaries, or their predecessors in the
Ordinary Course of Business). Without limiting the generality of the foregoing,
each person who is or was an employee or contractor of Larscom or any of its
Subsidiaries and who is or was involved in the creation or development of

                  (f) To Larscom's knowledge, neither Larscom nor any of its
Subsidiaries have ever infringed, misappropriated, or otherwise violated any
Intellectual Property of any third party. Without limiting the generality of the
foregoing and solely to Larscom's knowledge, neither (i) the products previously
or currently sold or under development by Larscom or any of its Subsidiaries, or
(ii) the business or activities previously or currently conducted by Larscom or
any of its Subsidiaries, has infringed, violated, or constituted a
misappropriation of any Intellectual Property of any third party. Neither
Larscom nor any of its Subsidiaries has received any complaint, claim, or notice
alleging any such infringement, violation, or misappropriation. Neither Larscom
nor any of its Subsidiaries has received any correspondence, requests or demands
since January 1, 2000, by third parties regarding the licensing of such third
party's patents, copyrights, trademarks or other Intellectual Property or
proprietary rights. Larscom and its Subsidiaries have never assumed, or agreed
to discharge or otherwise take responsibility for, any existing or potential
liability of any third party for infringement, misappropriation, or violation of
any Intellectual Property. To Larscom's knowledge, no other person or entity has
infringed, violated, or misappropriated, and no other person or entity is
currently, infringing, violating, or misappropriating, any material Larscom
Intellectual Property or any Intellectual Property that Larscom or any of its
Subsidiaries is authorized or licensed to use under any Larscom Material Inbound
License.

                  (g) To Larscom's knowledge, none of the software (including
firmware and other software embedded in hardware devices) developed (or
currently being developed), distributed, licensed, or sold by Larscom or any of
its Subsidiaries (collectively, the "Larscom Software") contains any bug,
defect, or error that materially and adversely affects, or would reasonably be
expected to materially and adversely affect, the use, functionality, or
performance of such Larscom Software or any product or system containing or used
in conjunction with such Larscom Software. To Larscom's knowledge, no Larscom
Software contains any "back door," "drop dead device," "time bomb," "Trojan
horse," "virus," or "worm" (as such terms are commonly understood in the
software industry) or any other code designed or intended to have, or capable of
performing, any of the following functions: (i) disrupting, disabling, harming,
or otherwise impeding in any manner the operation of, or providing unauthorized
access to, a computer system or network or other device on which such code is
stored or installed; or (ii) damaging or destroying any data or file without the
user's consent. No source code for any Larscom Software has been delivered,
licensed, or made available to any escrow agent or other person or entity. To
Larscom's knowledge, no event has occurred, and no circumstance or condition
exists, that (with or without notice or lapse of time) will, or could reasonably
be expected to, result in the delivery, license, or disclosure of the source
code for any Larscom Software to any other person.

                  (h) The execution and delivery of this Agreement and
consummation of the Merger will not result in (i) the breach of, or create on
behalf of any third party the right to terminate or modify, any Larscom Material
License, (ii) a loss of, or Lien on, any Larscom Intellectual Property, (iii)
the release, disclosure, or delivery of any Larscom Intellectual Property by or
to any escrow agent or other person, (iv) the grant, assignment, or transfer to
any other person of any license or other right or interest under, to, or in any
of the Larscom Intellectual Property, (v) either Verilink, the Surviving
Corporation, or any of their Subsidiaries being bound by or subject to, as a
result of Larscom's contracts and other legal obligations, any non-compete or
other restriction on the operation or scope of their respective businesses, or

Verilink, the Surviving Corporation, or any of their Subsidiaries being
obligated to pay any royalties or other amounts to any third party in excess of
those payable by Larscom or the Surviving Corporation, respectively, prior to
the Closing.

All filings and reports as to each Larscom Employee Plan required to have been

no audits, inquiries or proceedings pending or, to the knowledge of Larscom,
Larscom's Subsidiaries or their ERISA Affiliates, threatened by the IRS, DOL or
any other governmental entity with respect to any Larscom Employee Plan. Neither

benefit obligations for which contributions have not been made or properly
accrued and there are no benefit obligations which have not been accounted for
by reserves, or otherwise properly footnoted in accordance with GAAP, on the
financial statements of Larscom, which obligations are reasonably likely,
individually or in the aggregate, to have a Larscom Material Adverse Effect.

                  The assets of each Larscom Employee Plan that is funded are
reported at their fair market value on the books and records of such plan.

                  (e) Neither Larscom nor any ERISA Affiliate has ever
maintained, established, sponsored, participated in, contributed to, or is
obligated to contribute to, or otherwise incurred any obligation or liability

"multiemployer plan" (as defined in Section 3(37) of ERISA), any Employee
Benefit Plan subject to Title IV of ERISA or Section 412 of the Code, any
multiple employer plan (as defined in ERISA or the Code), or any "funded welfare
plan" within the meaning of

                                       28


Section 419 of the Code. Any Larscom Employee Plan intended to be qualified
under Section 401(a) of the Code and each trust intended to qualify under
Section 501(a) of the Code has either applied for or obtained a favorable
determination, notification, advisory and/or opinion letter, as applicable, as
to its qualified status from the IRS (and no such letter has been revoked nor
has revocation been threatened) or still has a remaining period of time under
applicable Treasury Regulations or IRS pronouncements in which to apply for such
letter and to make any amendments necessary to obtain a favorable determination.
To the knowledge of Larscom, for each Larscom Employee Plan that is intended to
be qualified under Section 401(a) of the Code, there has been no event,
condition or circumstance that has adversely affected or is likely to adversely
affect such qualified status. Except as specifically set forth in Section
3.16(e) of the Larscom Disclosure Schedule, no Larscom Employee Plan provides
health or death benefits that are not fully insured through an insurance
contract.

"voluntary employee's beneficiary association" within the meaning of Section
501(c)(9) of the Code. No Larscom Employee Plan holds securities issued by
Larscom, any of Larscom's Subsidiaries or any of their ERISA Affiliates.

                  (g) Each Larscom International Employee Plan has been
established, maintained and administered in material compliance with its terms
and conditions and with the requirements prescribed by any and all applicable
laws. No Larscom International Employee Plan has unfunded liabilities, that as
of the Effective Time, will not be offset by insurance or fully accrued. For
purposes of this Agreement, "Larscom International Employee Plan" shall mean
each Larscom Employee Plan that has been adopted or maintained by Larscom or any
ERISA Affiliate, whether informally or formally, or with respect to which
Larscom or any ERISA Affiliate will or may have any material liability, for the
benefit of employees who perform services outside the United States.

                  (h) Each Larscom Employee Plan, including, without limitation,
any Larscom International Employee Plan, is amendable and terminable
unilaterally by Larscom and any of Larscom's Subsidiaries which are a party
thereto or covered thereby at any time, including after the Effective Time,
without material liability to Larscom, the Surviving Corporation or any of their
Subsidiaries as a result thereof (other than for benefits accrued through the
date of termination or amendment and reasonable administrative expenses related
thereto), and no Larscom Employee Plan, plan documentation or agreement, summary
plan description or other written communication distributed generally to
employees by its terms prohibits Larscom or any of its Subsidiaries from
amending or terminating any such Larscom Employee Plan. The investment vehicles
used to fund Larscom Employee Plans may be changed at any time without incurring
a material sales charge, surrender fee or other similar expense.

                  (i) Neither Larscom nor any of its Subsidiaries is a party to
any oral or written (i) agreement with any current or former stockholder,
director, executive officer or other key employee of Larscom or any of its
Subsidiaries (A) the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving Larscom or
any of its Subsidiaries of the nature of any of the transactions contemplated by
this Agreement (either alone or upon the occurrence of any additional or
subsequent event), (B) providing any term of employment or compensation
guarantee or (C) providing severance

benefits or other benefits after the termination of employment of such director,
executive officer or key employee; (ii) agreement, plan or arrangement under
which any person may receive payments from Larscom or any of its Subsidiaries
that may be subject to the tax imposed by Section 4999 of the Code or that
constitute an "excess parachute payment" for such person under Section 280G of
the Code, without regard to Section 280G(b)(4); or (iii) agreement or plan
binding Larscom or any of its Subsidiaries, including any stock option plan or
agreement, stock appreciation right plan, restricted stock plan, stock purchase
plan or severance benefit plan, any of the benefits of which shall be increased,
or the vesting of the benefits of which shall be accelerated, by the execution
of this Agreement or the occurrence of any of the transactions contemplated by
this Agreement or the value of any of the benefits of which shall be calculated
on the basis of any of the transactions contemplated by this Agreement.

                  (j) None of the Larscom Employee Plans promises or provides
retiree medical or other retiree welfare benefits to any person, except as

represented, promised or contracted (whether in oral or written form) to any
employee (either individually or to employees as a group) or any other person
that such employee(s) or other person would be provided with retiree health,
except to the extent required by applicable law.

                  (k) Larscom has no current or future obligations respecting
any benefit liabilities under the Axel Johnson Inc. Retirement Plan, contingent
or otherwise. The circumstances giving rise to Larscom's relief from any such
current and future liabilities does not create any potential for liability under
Section 4069 of ERISA.

                  (l) Larscom has no current or future obligations respecting
any benefit liabilities under the Axel Johnson Inc. Retirement Restoration
Program, contingent or otherwise.

of, and have not received any notice alleging any violation with respect to, any
applicable provisions of any statute, law or regulation, and are, and have been,
in compliance with the Sarbanes-Oxley Act of 2002 and any related statutes, laws
or regulations, including the rules and regulations of The Nasdaq Stock Market,
Inc, except for failures to comply or violations which, individually or in the
aggregate, have not had and are not reasonably likely to have a Larscom Material
Adverse Effect.

         3.18     Permits.

  Larscom and each of its Subsidiaries have all permits, licenses and franchises
from Governmental Entities required to conduct their businesses as now being
conducted or as presently proposed to be conducted (the "Larscom Permits"),
except for such permits, licenses and franchises the lack of which, individually
or in the aggregate, have not resulted in, and are not reasonably likely to
result in, a Larscom Material Adverse Effect. Larscom and its Subsidiaries are
in compliance with the terms of the Larscom Permits, except where the failure to
so comply, individually or in the aggregate, is not reasonably likely to have a
Larscom Material Adverse Effect.

accurate list of all insurance policies maintained by, at the expense of, or for
the benefit of Larscom and any of its Subsidiaries and identifies any material
claims made thereunder since January 1, 1998. Each of Larscom and its
Subsidiaries maintains insurance policies (the "Larscom Insurance Policies")
with reputable insurance carriers against all risks of a character as are
usually insured against, and in such coverage amounts as are usually maintained,
by similarly situated companies in the same or similar businesses. Each Larscom
Insurance Policy is in full force and effect. Since January 1, 1998, neither
Larscom nor any of its Subsidiaries has received any notice or other
communication (in writing or otherwise) regarding any actual or possible (a)
cancellation or invalidation of any insurance policy (b) refusal of any coverage

adjustment in the amount of the premiums payable with respect to any insurance
policy.

reflected in the books and records of Larscom and its Subsidiaries as being
owned by Larscom and its Subsidiaries. All of said assets are owned by Larscom
and its Subsidiaries free and clear of any Liens, except for (i) any Lien for
current taxes not yet due and payable and (ii) immaterial Liens that have arisen
in the Ordinary Course of Business and that do not (in any case or in the
aggregate) materially detract from the value of the assets subject thereto or
materially impair the operations of Larscom or any of its Subsidiaries.

         3.21     Equipment and Leaseholds.

  All material items of equipment and other tangible assets owned by or leased

allowance for doubtful accounts not to exceed the allowance set forth in the
Larscom Balance Sheet).

                  (b) The gross revenue of Larscom in the second quarter of

consolidated statement of operations for the quarter ended March 31, 2004 and
condensed consolidated balance sheet as of March 31, 2004 included in Section
3.22(b) of the Larscom Disclosure will be consistent in all material respects
with the unaudited interim financial statements included in Larscom's Form 10-Q
for the quarter ended March 31, 2004.

                  (c) All of Larscom's and its Subsidiaries' existing inventory
(including all inventory that is reflected on the Larscom Balance Sheet, net of
any inventory reserves, and that has not been disposed of by Larscom or any of
its Subsidiaries since December 31, 2003) is of such quality and quantity as to

of such date, the Exchange Ratio is fair, from a financial point of view, to the
holders of Larscom Common Stock. A copy of the written opinion of Standard &
Poor's will be provided to Verilink solely for information purposes within one
business day following receipt thereof by Larscom.

         3.25     Section 203 of the DGCL Not Applicable.

         Verilink and the Merger Sub represent and warrant to Larscom that the
statements contained in this Article IV are true and correct, except as
expressly set forth herein or in the disclosure schedule delivered by Verilink
to Larscom on the date of this Agreement which is made a part hereof (the
"Verilink Disclosure Schedule"). The Verilink Disclosure Schedule will be
arranged in paragraphs corresponding to the lettered and numbered paragraphs
contained in this Agreement.

         4.1      Organization, Standing and Power.

  Verilink is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation, has all
requisite corporate power and authority to own, lease and operate its properties
and assets and to carry on its business as now being conducted and as proposed
to be conducted, and is duly qualified to do business and is in good standing as
a foreign corporation in each jurisdiction where the character of the properties
it owns, operates or leases or the nature of its activities makes such
qualification necessary, except for such failures to be so organized, qualified
or in good standing, individually or in the aggregate, which have not had, and
are not reasonably likely to have a Verilink Material Adverse Effect. For
purposes of this Agreement, the term "Verilink Material Adverse Effect" means
any material adverse change, event, circumstance or development with respect to,
or material adverse effect on, the business, assets, liabilities,
capitalization, condition (financial or other), or results of operations of
Verilink and its Subsidiaries, taken as a whole; provided, however, that none of
the following shall, in and of itself, be taken into account when determining
whether there has been, or will be, a Verilink Material Adverse Effect: (i) any
failure by Verilink to meet or exceed analysts' published revenues or earnings
predictions or any change in Verilink's stock price or trading volume, (ii) with
respect to the use of the term "Verilink Material Adverse Effect" in the

                                       33


representations and warranties contained in Section 4.7, any effect resulting
from the announcement or pendency of this Agreement or the Merger, or (iii)
other than with respect to the use of the term "Verilink Material Adverse
Effect" in the representations and warranties contained in Section 4.6, any
effect that results from changes affecting generally the industry or industries
in which Verilink or any of its Subsidiaries participates, the U.S. economy as a
whole or foreign economies in any locations where Verilink or any of its
Subsidiaries has material operations, or sales or customers unless such
condition shall disproportionately adversely affect Verilink or any of its
Subsidiaries.

Bylaws, or equivalent organizational documents. Such Verilink Charter Documents

applicable to Verilink or any of its Subsidiaries or any of its or their
properties or assets, except in the case of clauses (ii) and (iii) of this
Section 4.4(b) for any such conflicts, violations, breaches, defaults,
terminations, cancellations, accelerations or losses which, individually or in
the aggregate, are not, reasonably likely to have a Verilink Material Adverse
Effect. Section 4.4(b) of the Verilink Disclosure Schedule lists all consents,
waivers and approvals under any of Verilink's or any of its Subsidiaries'
agreements, licenses or leases required to be obtained in connection with the

to Verilink, Larscom or the Surviving Corporation as a result of the Merger or a
Verilink Material Adverse Effect.

Adverse Effect.

Proposal by the holders of a majority of the voting power of the outstanding
shares of Verilink Common Stock on the record date for the meeting of Verilink's
stockholders to consider the Verilink Voting Proposal (the "Verilink Meeting")
present or represented by proxy is the only vote of the holders of any class or
series of Verilink's capital stock or other securities necessary to approve the
Verilink Voting Proposal. There are no bonds, debentures, notes or other
indebtedness of Verilink having the right to vote (or convertible into, or
exchangeable for, securities having the right to vote) on any matters on which
stockholders of Verilink may vote.

                  circumstances referred to in Section 6.1(a)); or

                           (iii) adopt, approve or recommend, or propose to
                  adopt, approve or recommend, any Acquisition Proposal.

                  Notwithstanding the foregoing, the Verilink Board or the
Larscom Board may, in compliance with this Section 6.1, withdraw or modify or
propose to withdraw or modify its recommendation with respect to the Verilink
Voting Proposal or the Larscom Voting Proposal, as the case may be, publicly
indicate that it is doing so (and to the extent required in order to comply with
such Board's fiduciary duties under applicable law, as determined in good faith
by the applicable Board of Directors, may endorse or recommend such Superior
Proposal) if the Verilink Board or the Larscom Board, as the case may be,
determines in good faith (after consultation with outside counsel) that its
fiduciary obligations require it to do so, but only at a time that is prior to
the Specified Time and is after the second business day following receipt by
Larscom or Verilink, as the case may be, of written notice advising (x) whether
such action is taken in connection with an Acquisition Proposal and if so,
specifying the material terms and conditions of such Superior Proposal and
identifying the person making such Superior Proposal and (y) otherwise
specifying in reasonable detail the reasons and basis for such action.

                  (c) Notices; Additional Negotiations.

  Each party shall immediately advise the other party orally, with written
confirmation to follow promptly, of any Acquisition Proposal or any request for
nonpublic information in connection with any Acquisition Proposal, or of any
inquiry with respect to, or that could reasonably be expected to lead to, any
Acquisition Proposal, the material terms and conditions of any such Acquisition
Proposal or inquiry and the identity of the person making any such Acquisition
Proposal or inquiry. Neither party shall provide any information to or
participate in discussions or negotiations with (except for discussions as to
the existence of these provisions) the person or entity making any Acquisition
Proposal which constitutes a Superior Proposal or which could reasonably be
expected to result in a Superior Proposal until two business days after such
party has first notified the other party of such Acquisition Proposal as
required by the preceding sentence. The party receiving an Acquisition Proposal
shall (i) orally, and in writing within 24 hours of receipt thereof, keep the
other party fully informed of the status and material terms of any such
Acquisition Proposal, request or inquiry (including notifying the other party
orally and in writing of the identity of the person making such Acquisition
Proposal, request or inquiry, and of any material change to the terms of such
Acquisition Proposal) and (ii) if the other party to this Agreement shall make a
competing proposal, consider and cause its financial and legal advisors to
negotiate on its behalf in good faith with respect to the terms of such
competing proposal. Contemporaneously with providing any information to a third
party in connection with any such Acquisition Proposal, the party receiving such
Acquisition Proposal shall furnish a

                                       47


copy of such information to the other party to the extent that such copy has not
previously been provided to the other party. In addition to the foregoing,
Verilink or Larscom shall (A) provide the other party with at least 24 hours
prior notice (or such lesser prior notice as provided to the members of the
Verilink Board or to the members of the Larscom Board but in no event less than
eight hours) of any meeting of the Verilink Board or the Larscom Board at which
the Verilink Board or the Larscom Board is reasonably expected to consider an
Acquisition Proposal which constitutes a Superior Proposal or which could
reasonably be expected to result in a Superior Proposal and (B) provide the
other party with at least two business days prior written notice of a meeting of
the Verilink Board or the Larscom Board at which the Verilink Board or the
Larscom Board is reasonably expected to recommend a Superior Proposal to its
stockholders and together with such notice a copy of the definitive
documentation relating to such Superior Proposal to the extent that such copy
has not previously been provided to the other party.

                  (d) Certain Permitted Disclosure. Nothing contained in this
Section 6.1 or in Section 6.5 shall be deemed to prohibit either party from
taking and disclosing to its stockholders a position with respect to a tender
offer contemplated by Rules 14d-9 or 14e-2 promulgated under the Exchange Act
with regard to an Acquisition Proposal, if, in the good faith judgment of the
Verilink Board or the Larscom Board, as the case may be, based on the advice of
outside counsel, failure to so disclose would be inconsistent with its
obligations under applicable law.

                  (e) Cessation of Ongoing Discussions. Each party shall, and
shall cause its Subsidiaries and its and their Representatives to, cease
immediately all discussions and negotiations regarding any proposal that
constitutes, or could reasonably be expected to lead to, an Acquisition
Proposal. As of the date of this Agreement, each of Verilink and Larscom
represents that neither it nor any of its Subsidiaries is engaged, directly or
indirectly, in any discussions or negotiations with any other party with respect
to an Acquisition Proposal.

                  (f) Definitions. For purposes of this Agreement.

                  "Acquisition Proposal" means, with respect to any party, (i)
any inquiry, proposal or offer for a merger, consolidation, dissolution, sale of
substantial assets, tender offer, recapitalization, share exchange or other
business combination involving such party or any of its Subsidiaries, (ii) any
proposal for the issuance by such party or any of its Subsidiaries of over 20%
of its equity securities or the voting power of its equity securities or (iii)
any proposal or offer to acquire in any manner, directly or indirectly, over 20%
of the equity securities or the voting power of its equity securities or
consolidated total assets of such party; provided, however, in each case
Acquisition Proposal shall not include the Merger contemplated by this
Agreement; provided, further, that in the case of Verilink the term Acquisition
Proposal shall not include any inquiry, proposal or offer that does not require,
propose, contemplate, or would not be reasonably expected to result in, the
termination or abandonment of this Agreement and the Merger (an "Allowed
Proposal").

                  "Superior Proposal" means, with respect to any party, any
unsolicited, bona fide written proposal made by a third party to acquire,
directly or indirectly, pursuant to a tender or exchange offer, merger,
consolidation or other business combination or asset purchase, all or
substantially all of the assets of Verilink or Larscom, as the case may be, or a
majority of the total outstanding voting securities in the case of Verilink or
Larscom, as the case may be, and as

                                       48


a result of which the stockholders of Verilink or Larscom, as the case may be,
immediately preceding such transaction would hold less than fifty percent (50%)
of the voting power of the total outstanding equity interests in the surviving
or resulting entity of such transaction or any direct or indirect parent or
subsidiary thereof, on terms that the Board of Directors of Larscom or Verilink,
as the case may be, has in good faith concluded to be more favorable, from a
financial point of view, to its stockholders generally (in their capacities as
stockholders) than the transactions contemplated by this Agreement (following
consultation with outside and independent legal and financial advisors and after
taking into account all the terms and conditions of such proposal and this
Agreement (including any proposal by either party to amend the terms of this
Agreement) and on the terms proposed, taking into account all financial,
regulatory, legal and other aspects of such proposal; provided, however, that no
Acquisition Proposal shall be deemed to be a Superior Proposal if any financing
required to consummate the Acquisition Proposal is not committed, and in the
case of Verilink, is an Allowed Proposal.

         6.2      Joint Proxy Statement/Prospectus and Registration Statement.

                  (a) As promptly as practicable after the execution of this
Agreement, Larscom and Verilink shall jointly prepare and file with the SEC a
joint proxy statement/prospectus (together with any amendments thereof or
supplements thereto, the "Joint Proxy Statement/Prospectus") to be sent to the
stockholders of Larscom and Verilink in connection with the Larscom Meeting and
Verilink Meeting, respectively, and Verilink shall prepare and file with the SEC
a registration statement on Form S-4 in which the Joint Proxy
Statement/Prospectus will be included as a prospectus, to register under the
Securities Act the issuance of shares of Verilink Common Stock in connection
with the Merger (together with all amendments thereto, the "Registration
Statement"). Each of Verilink and Larscom shall provide promptly to the other
party such information concerning its business and financial statements and
affairs as, in the reasonable judgment of the providing party or its counsel,
may be required or appropriate for inclusion in the Joint Proxy Statement/
Prospectus and the Registration Statement, or in any supplements or amendments
thereto, and cause its counsel and auditors to cooperate with the other's
counsel and auditors in the preparation of the Joint Proxy Statement/Prospectus
and the Registration Statement. Each of Larscom and Verilink shall respond to
any comments of the SEC and shall use its respective commercially reasonable
efforts to have the Joint Proxy Statement/Prospectus cleared by the SEC and the
Registration Statement declared effective under the Securities Act as promptly
as practicable after such filings and Larscom and Verilink shall cause the Joint
Proxy Statement/Prospectus to be mailed to their respective stockholders at the
earliest practicable time after both the Joint Proxy Statement/Prospectus is
cleared by the SEC and the Registration Statement is declared effective under
the Securities Act; provided, however, that the parties shall consult and
cooperate with each other in determining the appropriate time for mailing the
Joint Proxy Statement/Prospectus in light of the date sets for the Larscom
Meeting and the Verilink Meeting. Each of Larscom and Verilink shall notify the
other promptly upon the receipt of any comments from the SEC or its staff or any
other government officials and of any request by the SEC or its staff or any
other government officials for amendments or supplements to the Registration
Statement, the Joint Proxy Statement/Prospectus or any filing pursuant to
Section 6.2(c) or for additional information and shall supply the other with
copies of all correspondence between such party or any of its representatives,
on the one hand, and the SEC, or its staff or any other government officials, on
the other hand, with respect to the Registration Statement, the Joint Proxy
Statement/Prospectus,

                                       49


the Merger or any filing pursuant to Section 6.2(c). Each of Larscom and
Verilink shall use commercially reasonable efforts to cause all documents that
it is responsible for filing with the SEC or other regulatory authorities under
this Section 6.2 to comply in all material respects with all applicable
requirements of law and the rules and regulations promulgated thereunder.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Joint Proxy Statement/Prospectus, the Registration Statement
or any filing pursuant to Section 6.2(b), Larscom or Verilink, as the case may
be, shall promptly inform the other of such occurrence and cooperate in filing
with the SEC or its staff or any other Governmental Entity or government
officials, and/or mailing to stockholders of Larscom and Verilink, such
amendment or supplement.

                  (b) Each of Verilink and Larscom agrees, as to itself and its
Subsidiaries, that none of the information supplied or to be supplied by it for
inclusion or incorporation by reference in (i) the Registration Statement will,
at the time the Registration Statement becomes effective under the Securities
Act, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, (ii) the Joint Proxy Statement/Prospectus will, at the
time of first mailing to the Verilink stockholders or Larscom stockholders or at
the time of the Verilink Meeting or Larscom Meeting, contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they are made, not misleading, or (iii) any filing pursuant to Rule 165
and 425 under the Securities Act or Rule 14a-12 under the Exchange Act (each a
"Regulation M-A Filing"), when taken together with the Joint Proxy
Statement/Prospectus, will, at the time of filing with the SEC or, if
applicable, at the time first mailed or otherwise communicated to Verilink or
Larscom stockholders, contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein, in
the light of the circumstances under which they are made, not misleading.
Notwithstanding the foregoing, no representation or warranty is made by Verilink
with respect to statements made or incorporated by reference therein about
Larscom or supplied by Larscom for inclusion or incorporation by reference in
the Registration Statement, Joint Prospectus/Proxy Statement or Regulation M-A
Filing and no representation or warranty is made by Larscom with respect to
statements made or incorporated by reference therein about Verilink that are
supplied by the Verilink for inclusion or incorporation by reference in the
Registration Statement, the Joint Proxy Statement/ Prospectus or any Regulation
M-A Filing.

                  (c) Larscom and Verilink shall promptly make all necessary
filings with respect to the Merger under the Securities Act, the Exchange Act,
applicable Blue Sky Laws, the applicable laws of any other jurisdiction and the
rules and regulations thereunder; provided, however, that neither Verilink,
Larscom nor the Surviving Corporation shall be required (i) to qualify to do
business as a foreign corporation in any jurisdiction in which it is not now
qualified or (ii) to file a general consent to service of process in any
jurisdiction.

         6.3      [Reserved]

         6.4      Access to Information.

                                       50


  From and after the date of this Agreement until the earlier of the termination
of this Agreement in accordance with Article VIII and the Effective Time, each
of Larscom and Verilink shall (and shall cause each of its Subsidiaries to)
afford to the other party's Representatives, reasonable access, during normal
business hours during the period prior to the Effective Time, to all its
properties, books, work papers, Tax Returns, contracts, commitments, personnel,
customers, suppliers and vendors and records and, during such period, each of
Larscom and Verilink shall (and shall cause each of its Subsidiaries to) furnish
promptly to the other party (a) a copy of each report, schedule, registration
statement and other document filed or received by it during such period pursuant
to the requirements of federal or state securities laws or the securities laws
of any other applicable jurisdiction and (b) all other information concerning
its business, properties, assets and personnel as the other party may reasonably
request. Each of Larscom and Verilink will hold any such information which is
nonpublic in confidence in accordance with the Confidentiality Agreement. No
information or knowledge obtained in any investigation pursuant to this Section
6.4 or otherwise shall affect or be deemed to modify any representation or
warranty contained in this Agreement or the conditions to the obligations of the
parties to consummate the Merger.

                  (a) Verilink, acting through the Verilink Board, shall take

call, give notice of, convene and hold as promptly as practicable after the
declaration of effectiveness of the Registration Statement, the Verilink
Stockholders Meeting for the purpose of considering and voting upon the Verilink
Voting Proposal. Except as expressly permitted by Section 6.1(b), to the fullest

committee thereof shall withdraw or modify, or propose or resolve to withdraw or
modify, in a manner adverse to Larscom, the recommendation of the Verilink Board
that Verilink's stockholders vote in favor of the Verilink Voting Proposal.
Notwithstanding anything to the contrary contained in this Agreement, after
consultation with Larscom, Verilink may adjourn or postpone the Verilink
Stockholder Meeting to the extent necessary to ensure that any required
supplement or amendment to the Joint Proxy Statement/Prospectus is provided to
Verilink's stockholders or, if, as of the time for which the Verilink
Stockholders Meeting is originally scheduled (as set forth in the Joint Proxy
Statement/Prospectus), there are insufficient shares of Verilink Common Stock
represented (either in person or by proxy) to constitute a quorum necessary to
conduct the business of the Verilink Stockholders Meeting.

                  (b) Larscom, acting through the Larscom Board, shall take all
actions in accordance with applicable law, its Certificate of Incorporation and

                                       51


recommendation in the Joint Proxy Statement/Prospectus, and (ii) neither the
Larscom Board nor any committee thereof shall withdraw or modify, or propose or
resolve to withdraw or modify, in a manner adverse to Verilink, the
recommendation of the Larscom Board that Larscom's stockholders vote in favor of
the Larscom Voting Proposal. Notwithstanding anything to the contrary contained
in this Agreement, after consultation with Verilink, Larscom may adjourn or
postpone the Larscom Stockholders Meeting to the extent necessary to ensure that
any required supplement or amendment to the Joint Proxy Statement/Prospectus is
provided to Larscom's stockholders or, if, as of the time for which the Larscom
Stockholders Meeting is originally scheduled (as set forth in the Joint Proxy
Statement/ Prospectus), there are insufficient shares of Larscom Common Stock
represented (either in person or by proxy) to constitute a quorum necessary to
conduct the business of the Larscom Stockholders Meeting.

                  (a) Subject to the terms hereof, including Section 6.6(b), and
applicable law, Verilink and Larscom shall each use commercially reasonable

governmental request thereunder, and (C) any other applicable law, and (iv)
execute or deliver any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of, this
Agreement. Verilink and Larscom shall cooperate with each other in connection
with the making of all such filings, including providing copies of all such
documents to the non-filing party and its advisors prior to filing and, if
requested, accepting all reasonable additions, deletions or changes suggested in
connection therewith. Verilink and Larscom shall use their respective
commercially reasonable efforts to furnish to each other all information

                  (b) Subject to the terms hereof, Larscom and Verilink agree,
and shall cause each of their respective Subsidiaries, to cooperate and to use
their respective commercially reasonable efforts to obtain any government
clearances or approvals required for Closing under the HSR Act, if applicable,
and any other federal, state or foreign law or, regulation or decree designed to
prohibit, restrict or regulate actions for the purpose or effect of
monopolization or restraint of trade reasonably determined by the parties to
apply (collectively "Antitrust Laws"), to respond to any government requests for
information under any Antitrust Law, and to contest

                                       52


and resist any action, including any legislative, administrative or judicial
action, and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order (whether temporary, preliminary or
permanent) (an "Antitrust Order") that restricts, prevents or prohibits the
consummation of the Merger or any other transactions contemplated by this
Agreement under any Antitrust Law. The parties hereto will consult and cooperate
with one another, and consider in good faith the views of one another, in
connection with any analyses, appearances, presentations, memoranda, briefs,
arguments, opinions and proposals made or submitted by or on behalf of any party
hereto in connection with proceedings under or relating to any Antitrust Law.
Notwithstanding anything in this Agreement to the contrary in this Section 6.6,
neither Larscom nor Verilink shall be under any obligation to (i) make
proposals, execute or carry out agreements or submit to orders providing for the
sale or other disposition or holding separate (through the establishment of a
trust or otherwise) of any material assets or categories of assets of Larscom or
Verilink or the holding separate of the shares of Larscom Common Stock (or
shares of stock of the Surviving Corporation) or imposing or seeking to impose
any material limitation on the ability of Larscom or Verilink to conduct its
business or own such assets or to acquire, hold or exercise full rights of
ownership of the shares of Larscom Common Stock (or shares of stock of the
Surviving Corporation) or (ii) take any action under this Section 6.6 if the
United States Department of Justice or the United States Federal Trade
Commission or any applicable foreign regulatory agency authorizes its staff to
seek a preliminary injunction or restraining order to enjoin consummation of the
Merger.

                  (c) Each of Verilink and Larscom shall give (or shall cause
their respective Subsidiaries to give) any notices to third parties, and use,
and cause their respective Subsidiaries to use, their commercially reasonable
efforts to obtain any third party consents related to or required in connection
with the Merger that are (A) necessary to consummate the transactions
contemplated hereby, (B) disclosed or required to be disclosed in the Verilink
Disclosure Schedule or Larscom Disclosure Schedule, as the case may be, or (C)
required to prevent a Verilink Material Adverse Effect or a Larscom Material
Adverse Effect from occurring prior to or at the Effective Time.

         6.7      Public Disclosure.

  From and after the date of this Agreement until the earlier of the termination
of this Agreement in accordance with Article VIII and the Effective Time each
party shall not, and shall not permit any of its Representatives to, issue any
press release or otherwise publicly disseminate any document or other written
material relating to the Merger or any other transaction contemplated by this
Agreement unless (a) the other party shall have approved such press release or
written material (such approval not to be unreasonably withheld or delayed) or
(b) such party shall have been advised by its outside legal counsel that the
issuance of such press release or dissemination of such written material is
required by law or The Nasdaq Stock Market, Inc. rules and regulations and such
party shall have consulted with the other party prior to issuing such press
release or disseminating such written material.

         6.8      Section 368(a) Reorganization.

  Neither Larscom nor Verilink nor any of their Subsidiaries shall take any
action that would reasonably be expected to cause the Merger to fail to qualify
as a reorganization within the

                                       53


meaning of Section 368(a) of the Code. Verilink and Larscom shall each make all
commercially reasonable efforts to cause the Merger to be treated as a
reorganization within the meaning of Section 368(a) of the Code.

         6.9      Affiliate Legends.

  Section 6.9 of the Larscom Disclosure Schedule sets forth a list of those
persons who are, in Larscom's reasonable judgment, "affiliates" of Larscom
within the meaning of Rule 145 promulgated under the Securities Act ("Rule 145
Affiliates"). Larscom shall notify Verilink in writing of any change in the
identity of its Rule 145 Affiliates prior to the Closing. Verilink shall be
entitled to place appropriate legends on the Verilink Common Stock to be
received by Rule 145 Affiliates of Larscom in the Merger reflecting the
restrictions set forth in Rule 145 promulgated under the Securities Act and to
issue appropriate stop transfer instructions to the transfer agent for Verilink
Common Stock.

  Verilink shall use commercially reasonable best efforts (a) to cause the
Verilink Common Stock to be issued pursuant to this Agreement to the holders of
Larscom Common Stock in connection with the Merger to be approved for listing
upon the Effective Time on the Nasdaq Stock Market, if applicable, and (b) to
cause the Verilink Common Stock issued upon the exercise of converted Larscom
Stock Options and Larscom Warrants to be approved for listing on the Nasdaq

  From and after the date of this Agreement until the earlier of the termination
of this Agreement in accordance with Article VIII and the Effective Time, each
party shall give the other party the opportunity to participate in the defense
or settlement of any stockholder litigation relating to this Agreement or any of
the transactions contemplated by this Agreement, and shall not settle any such
litigation without the other party's prior written consent, which shall not be
unreasonably withheld or delayed.

         6.12     Indemnification.

                  (a) From and after the Effective Time, Verilink shall, and
shall cause the Surviving Corporation to, for a period of six years from the
Effective Time, indemnify, defend and hold harmless each present and former
director and officer of Larscom (the "Indemnified Parties"), against any costs
or expenses (including reasonable attorneys' fees), judgments, fines, losses,
claims, damages, liabilities or amounts paid in settlement incurred in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of or pertaining
to matters existing or occurring at or prior to the Effective Time (including
for acts or omissions occurring in connection with the approval of this
Agreement and the consummation of the transactions contemplated hereby), whether
asserted or claimed prior to, at or after the Effective Time, to the fullest
extent that Larscom would have

                                       54


been permitted under Delaware law, the Sarbanes-Oxley Act of 2002 and any
related statutes laws or regulations, the Larscom Charter Documents and any
agreements for indemnification in effect on the date hereof to indemnify an
Indemnified Party, in the forms provided by Larscom to Verilink prior to the
date hereof, (and Verilink and the Surviving Corporation shall also advance
expenses as incurred to the fullest extent permitted under Delaware law, the
Sarbanes-Oxley Act of 2002 and any related statutes laws or regulations and such
Larscom Charter Documents and the agreements set forth on Section 6.12(a) of the
Larscom Disclosure Schedule, provided the Indemnified Party to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such Indemnified Party is not entitled to indemnification).
Neither Verilink nor the Surviving Corporation shall amend, appeal or otherwise
modify the indemnification or exculpation from liability or other similar
provisions set forth in the Restated Certificate or the current bylaws of
Verilink for a period of six years after the Effective Time in any manner that
would adversely affect the rights thereunder of any person who, immediately
prior to the Effective Time, was an indemnified party under the indemnification
or exculpation from liability provisions of the Larscom Charter Documents.

                  (b) Prior to the Effective Time, Larscom shall purchase and
pay for directors' and officers' liability insurance tail coverage covering
those persons who are currently covered by Larscom's directors' and officers'
liability insurance policy (a copy of which has been heretofore delivered or
made available to Verilink) with coverage in the amount of $10,000,000 and scope
at least as favorable as provided to Larscom's directors and officers with
respect to claims arising from facts or events which occurred on or before the
Effective Time (including for acts or omissions occurring in connection with the
approval of this Agreement and the consummation of the transactions contemplated
hereby); provided that Verilink will pay one-half the cost of such tail coverage
to Larscom at the time Larscom purchases such coverage and to the extent such
payment does not exceed the limit set forth on Schedule 6.12(b) of the Verilink
Disclosure Schedule.

                  (c) In the event that Verilink or the Surviving Corporation or
any of their respective successors or assigns (i) consolidates with or merges
into any other person and is not the continuing or surviving corporation or
entity of such consolidation or merger or (ii) transfers or conveys all or
substantially all its properties and assets to any person, then, and in each
such case, Verilink shall cause proper provisions to be made so that the
successors and assigns of Verilink or the Surviving Corporation, as the case may
be, assume the obligations set forth in this Section 6.12.

                  (d) The provisions of this Section 6.12 are intended to be in
addition to the rights otherwise available to the current officers and directors
of Larscom by law, charter, statute, bylaw or agreement, and shall operate for
the benefit of, and shall be enforceable by, each of the Indemnified Parties,
their heirs and their representatives. The obligations of Verilink and the
Surviving Corporation under this Section 6.12 shall not be terminated or
modified in such a manner as to adversely affect any Indemnified Party to whom

         6.13     Notification of Certain Matters.

  Larscom shall give prompt notice to Verilink, and Verilink shall give prompt
notice to Larscom, of the occurrence, or failure to occur, of any event, which
occurrence or failure to occur would be reasonably likely to cause (a) (i) any
representation or warranty of such party contained in this Agreement that is
qualified as to materiality to be untrue or inaccurate in any respect or (ii)
any other representation or warranty of such party contained in this Agreement
to be untrue or inaccurate in any material respect, in each case at any time
from and after the date of this Agreement until the Effective Time, or (b) any
material failure of Verilink and the Merger Sub or Larscom, as the case may be,
or of any officer, director, employee or agent thereof, to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it under this Agreement. Notwithstanding the above, the delivery of any notice
pursuant to this Section will not limit or otherwise affect the remedies
available hereunder to the party receiving such notice or the conditions to such
party's obligation to consummate the Merger.

         6.14     Exemption from Liability Under Section 16(b).

                  (a) The Larscom Board, or a committee thereof consisting of
non-employee directors (as such term is defined for purposes of Rule 16b-3(d)
under the Exchange Act), and the Verilink Board, or a committee thereof
consisting of non-employee directors (as such term is defined for purposes of
Rule 16b-3(d) under the Exchange Act) shall, respectively, adopt resolutions in
advance of the Effective Time providing that the receipt by Larscom Insiders (as
defined below) of Verilink securities in exchange for shares of Larscom Common
Stock, and of options and warrants to purchase Verilink securities upon
assumption and conversion of Larscom Stock Options and Warrants, in each case
pursuant to the transactions contemplated hereby and to the extent such
securities are listed in the Section 16 Information, is intended to be exempt
pursuant to Rule 16b-3 under the Exchange Act.

                  (b) For purposes of Section 6.14(a), "Section 16 Information"
shall mean information regarding Larscom Insiders and the number of shares of
Larscom Common Stock or other Larscom equity securities deemed to be
beneficially owned by each such Larscom Insider and expected to be exchanged for
Verilink securities, or options or warrants to purchase Verilink securities, in
each case, in connection with the Merger which shall be provided by Larscom to
Verilink no later than 10 business days prior to the Closing.

                  (c) For purposes of Section 6.14(a), "Larscom Insiders" shall
mean those officers and directors of Larscom who are subject to the reporting
requirements of Section 16(a) of the Exchange Act as listed in the Section 16
Information.

         6.15     [Reserved]

         6.16     Employee Benefits.

  Following the Effective Time, Verilink will give each Continuing Employee full
credit for (i) prior service with Larscom or its Subsidiaries for purposes of
(A) eligibility and vesting under any Employee Benefit Plan of Verilink (each a
"Verilink Benefit Plan"), (B) determination of benefits levels under any
Verilink Employee Plan or policy relating to vacation or severance, (C)

                                       56


determination of "retiree" status under any Verilink Employee Plan, and (ii) any
annual deductibles, co-payments or such other expenses required under any
Larscom health or other Larscom Employee Plan that are paid during the year of
the Merger prior to the Effective Time in satisfying any applicable deductible,
out-of-pocket or other such requirements for the corresponding period under any
Verilink health or other Verilink Employee Plan, in each case for which the
Continuing Employee is otherwise eligible and in which the Continuing Employee
is offered participation, but except where such crediting would (i) result in a
duplication of benefits or (ii) otherwise cause Verilink or its Subsidiaries or
any Verilink Employee Plan or trust relating thereto to accrue or pay for
benefits that accrued in or are payable for any time period prior to the
Effective Time. Verilink agrees that each Continuing Employee shall be eligible
to either: (A) participate in Verilink Employee Plans as permitted by the terms
of such Verilink Employee Plans, (B) participate in Larscom Employee Plans that
are continued by Verilink, or (C) a combination of clauses (A) and (B) so that
each Continuing Employee is eligible for benefits that are substantially similar
in the aggregate to those of similarly situated employees of Verilink, and so
that no Continuing Employee incurs a gap in coverage solely as a result of the
Merger. "Continuing Employee" shall mean any employee of Larscom who continues
employment with Verilink or the Surviving Corporation after the Effective Time.
Nothing in this Section 6.16 or elsewhere in this Agreement shall be construed
to create a right in any employee to employment with Verilink or the Surviving
Corporation and the employment with any Continuing Employee shall be "at will"
employment. Following the Effective Time, Verilink agrees to comply with
Larscom's severance policies with respect to Larscom employees that are not
Continuing Employees to the extent such severance policies are set forth in
Section 3.16(a) of the Larscom Disclosure Schedule and such severance benefits
are not paid prior to the Effective Time.

         6.17     Termination of Employee Benefit Plans.

  Effective immediately prior to the Effective Time, Larscom shall terminate any
and all group severance, separation or salary continuation plans, programs or
arrangements, and shall terminate any and all Larscom Employee Plans which are
intended to include a Code Section 401(k) arrangement (unless Verilink consents,
as evidenced by written notice to Larscom, to the continuation of any such plan,
program or arrangement, which consent shall not be unreasonably withheld)
(collectively, "Larscom Terminating Plan(s)"). Verilink agrees that the
Continuing Employees shall be eligible to participate, to substantially the
extent they were eligible to participate in any Larscom Terminating Plan, in the
corresponding Verilink Employee Plan regarding group severance, separation or
salary continuation and in the corresponding Verilink Employee Plan intended to
include a Code Section 401(k) arrangement, program or arrangement, as promptly
following the Effective Time, as is permitted by the terms of such Verilink
Employee Plan, program or arrangement. Unless Verilink provides such written
consent to Larscom, no later than three business days prior to the Effective
Time, Larscom shall provide Verilink with evidence that such Larscom Terminating
Plan(s) have been terminated (effective immediately prior to the Effective Time)
pursuant to resolutions of the Larscom Board. The form and substance of such
resolutions shall be subject to review and approval of Verilink. Larscom also
shall take such other actions in furtherance of terminating such Larscom
Terminating Plan(s) as Verilink may reasonably require.

                                       57

Cooley Godward LLP tax representation letters in customary form. Verilink and
Larscom shall each confirm to Powell, Goldstein, Frazer & Murphy LLP and to
Cooley Godward LLP the accuracy and completeness as of the Effective Time of the
tax representation letters delivered pursuant to the immediately preceding
sentence. Verilink and Larscom shall use all reasonable efforts prior to the
Effective Time to cause the Merger to qualify as a tax-free reorganization under
Section 368(a)(1) of the Code. Following delivery of the tax representation
letters pursuant to the first sentence of this Section 6.18, each of Verilink
and Larscom shall use its reasonable efforts to cause Powell, Goldstein, Frazer
& Murphy LLP and Cooley Godward LLP, respectively, to deliver to it a tax
opinion satisfying the requirements of Item 601 of Regulation S-K promulgated
under the Securities Act. In rendering such opinions and the opinions required
pursuant to Sections 7.2(c) and 7.3(c), each of such counsel shall be entitled
to rely on the tax representation letters referred to in this Section 6.18.

         6.19     Registration Rights Agreement.

  Prior to the Closing, Verilink shall enter into a Registration Rights
Agreement, substantially in the form attached hereto as Exhibit C (the
"Registration Rights Agreement"), with the stockholders listed on the signature
pages thereto, which agreement will be effective at the Effective Time.

amount equal to the Verilink Expenses, and if Larscom shall consummate within 12
months of such termination an Acquisition Transaction that was first disclosed,
announced, commenced, submitted or made prior to termination or within 60 days

$1,200,000.

                  (d) Verilink shall pay Larscom a termination fee of $1,000,000

Proposal for Verilink shall have been disclosed, announced, commenced, submitted
or made and if Verilink shall consummate within 12 months of such termination an
Acquisition Transaction that was first disclosed, announced, commenced,
submitted or made prior to termination or within 60 days after termination, then
Verilink shall prior to the date of such consummation pay Larscom a fee of
$1,000,000 plus the

                                       65


Larscom Expenses provided that the aggregate of all such payments by Larscom to
Verilink pursuant to this Section 8.3(e) shall not exceed $1,200,000.

                  (f) For purposes of this Agreement, "Acquisition Transaction"
shall mean any of the following transactions (other than the transaction
contemplated by this Agreement): (i) a sale or other disposition by Larscom or
Verilink of business or assets representing more than 50% of its net revenues,
net income or assets immediately prior to such sale; (ii) the acquisition by any
person or group (including by way of a tender offer or an exchange offer or

ownership or a right to acquire beneficial ownership of more than 50% of the
outstanding voting power or equity interest in Larscom or Verilink; or (iii) a
merger, consolidation, business combination or similar transaction involving

                  (g) The parties acknowledge that the agreements contained in
this Section 8.3 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, the parties would not enter into
this Agreement. If one party fails to promptly pay to the other any termination
fee due hereunder, the defaulting party shall pay the costs and expenses
(including legal fees and expenses) in connection with any action, including the
filing of any lawsuit or other legal action, taken to collect payment, together
with interest on the amount of any unpaid fee at the publicly announced prime
rate of Citibank, N.A., plus two percent per annum, compounded quarterly, from
the date such termination fee was required to be paid. Payment of the
termination fee described in this Section 8.3 shall not be in lieu of damages
incurred in the event of a breach of this Agreement described in clause (i) of
Section 8.2.

         8.4      Amendment.

  This Agreement may be amended by the parties hereto, by action taken or
authorized by their respective Boards of Directors, at any time before or after
approval of the matters presented in connection with the Merger by the
stockholders of any of the parties; provided, however, that after any such
approval, no amendment shall be made which by applicable law requires further
approval by such stockholders without such further approval; and provided,
further, that an amendment made subsequent to adoption of the Agreement by the
stockholders of Verilink or Larscom without such further approval shall not (a)
alter or change the amount or kind of consideration to be received upon
conversion of the Larscom Common Stock, or (b) alter or change any of the terms
and conditions of the Agreement if such alteration or change would adversely
affect the stockholders of Verilink or Larscom. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

         8.5      Extension; Waiver.

or authorized by their respective Boards of Directors, may, to the extent
legally allowed, (a) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions contained

                                       66


herein. Any agreement on the part of a party hereto to any such extension or
waiver shall be valid only if set forth in a written instrument signed on behalf
of such party. No extension or waiver in any one instance shall be deemed to
extend to any prior or subsequent instance. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of such rights.

         9.3      Entire Agreement.

  This Agreement (including the Schedules and Exhibits hereto and the documents
and instruments referred to herein that are to be delivered at the Closing)
constitutes the entire agreement among the parties to this Agreement and
supersedes any prior understandings, agreements or representations by or among
the parties hereto, or any of them, written or oral, with respect to the subject
matter hereof; provided that the Confidentiality Agreement shall remain in

third-party beneficiary hereto.

         9.5      Assignment.

  Neither this Agreement nor any of the rights, interests or obligations under
this Agreement may be assigned or delegated, in whole or in part, by operation
of law or otherwise by any of the parties hereto without the prior written

consent shall be null and void. Subject to the preceding sentence, this
Agreement shall be binding upon, inure to the benefit of, and be enforceable by,
the parties hereto and their respective successors and permitted assigns.

         9.6      Severability.

  Any term or provision of this Agreement that is invalid or unenforceable in
any situation in any jurisdiction shall not affect the validity or
enforceability of the remaining terms and provisions hereof or the validity or
enforceability of the offending term or provision in any other situation or in
any other jurisdiction. If the final judgment of a court of competent
jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties hereto agree that the court making such determination
shall have the power to limit the term or provision, to delete specific words or
phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Agreement shall be enforceable as so modified. In the event such court does
not exercise the power granted to it in the prior sentence, the parties hereto
agree to replace such invalid or unenforceable term or provision with a valid
and enforceable term or provision that will achieve, to the extent possible, the
economic, business and other purposes of such invalid or unenforceable term.

         9.7      Counterparts and Signature.

  This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original but all of which together shall be considered one
and the same agreement and shall become effective when counterparts have been
signed by each of the parties hereto and delivered to the other parties, it
being understood that all parties need not sign the same counterpart. This
Agreement may be executed and delivered by facsimile transmission.

  When reference is made in this Agreement to an Article or a Section, such
reference shall be to an Article or Section of this Agreement, unless otherwise
indicated. The table of contents, table of defined terms and headings contained
in this Agreement are for convenience of reference only and shall not affect in
any way the meaning or interpretation of this Agreement. The language used in

to express their mutual intent, and no rule of strict construction shall be
applied against any party. Whenever the context may require, any pronouns used
in this Agreement shall include the corresponding masculine, feminine or neuter
forms, and the singular form of nouns and pronouns shall include the plural, and
vice versa. Any reference to any federal, state, local or foreign statute or law
shall be deemed also to refer to all rules and regulations promulgated
thereunder, unless the context requires otherwise. Whenever the words "include,"
"includes" or "including" are used in this Agreement, they shall be deemed to be
followed by the words "without limitation." No summary of this Agreement
prepared by any party shall affect the meaning or interpretation of this

jurisdiction) that would cause the application of laws of any jurisdictions
other than those of the State of Delaware.

         9.10     Consent to Jurisdiction; Venue.

  In any action or proceeding between any of the parties arising out of or
relating to this Agreement or any of the transactions contemplated by this
Agreement, each of the parties: (a) irrevocably and unconditionally consents and
submits to the exclusive jurisdiction and venue of the state courts of the State
of Delaware and to the jurisdiction of the United States District Court for the
District of Delaware, and (b) agrees that all claims in respect of such action
or proceeding may be heard and determined exclusively in any Delaware state or
federal court sitting in the State of Delaware.

         9.11     Remedies.

  Except as otherwise provided herein, any and all remedies herein expressly
conferred upon a party will be deemed cumulative with and not exclusive of any
other remedy conferred hereby, or by law or equity upon such party, and the
exercise by a party of any one remedy will not preclude the exercise of any
other remedy. The parties hereto agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
