                            1st Amendment to Loan and
                               Security Agreement

Borrower:         Osicom Technologies, Inc., a Delaware corporation
                  (formerly known as Cray Communications, Inc.)
Address:          2800 28th Street, Suite 100
                  Santa Monica, California 90405

Date:             April 16, 1999

      This First Amendment (the "Amendment") to Loan and Security Agreement (the
"Loan Agreement") is entered into by and between Coast Business Credit(R), a
division of Southern Pacific Bank (fka Southern Pacific Thrift & Loan
Association) ("Coast"), and Osicom Technologies, Inc., a Delaware corporation,
formerly known as Cray Communications, Inc. ("Borrower"). The Loan Agreement and
Schedule, as modified by this Amendment, shall for all purposes be deemed to be,
and the same shall constitute an integral part of the Loan Agreement and
Schedule. (Definitions and certain terms used in this Amendment shall have the
meanings set forth in the Loan Agreement, the Schedule and all other documents
and agreements executed in connection therewith or in furtherance thereof).

      For good and valuable consideration, receipt of which is hereby
acknowledged, the Loan Agreement is hereby amended in the following respects:

SECTION 1 OF THE LOAN AGREEMENT (with respect to Loans) is supplemented as
follows:

      A subsection 1.1a is added which reads as follows:

    1.1a Letters of Credit. At the request of Borrower, Coast may, in its sole
discretion, arrange for the issuance of letters of credit for the account of
Borrower (collectively, "Letters of Credit"), by issuing guarantees to the
issuer of the letter of credit or by other means. All Letters of Credit shall be
in form and substance satisfactory to Coast in its sole discretion. The
aggregate face amount of all outstanding Letters of Credit from time to time
shall not exceed the amount shown on the Schedule (the "Letter of Credit
Sublimit"), and shall be reserved against Loans which would otherwise be
available hereunder. Borrower shall pay all bank charges for the issuance of
Letters of Credit. Any payment by Coast under or in connection with a Letter of
Credit shall constitute a Loan hereunder on the date such payment is made. Each
Letter of Credit shall have an expiration date no later than thirty (30) days
prior to the Maturity Date. Borrower hereby agrees to indemnify, save, and hold
Coast harmless from any loss, cost, expense, or liability, including, without
limitation, payments made by Coast, expenses, and reasonable attorneys' fees
incurred by Coast
<PAGE>

arising out of or in connection with any Letters of Credit. Borrower agrees to
be bound by the regulations and interpretations of the issuer of any Letters of
Credit guarantied by Coast and opened for Borrower's account or by Coast's
interpretations of any Letter of Credit issued by Coast for Borrower's account,
and Borrower understands and agrees that Coast shall not be liable for any
error, negligence, or mistake, whether of omission or commission, in following
Borrower's instructions or those contained in the Letters of Credit or any
modifications, amendments, or supplements thereto. Borrower understands that
Letters of Credit may require Coast to indemnify the issuing bank for certain
costs or liabilities arising out of claims by Borrower against such issuing
bank. Borrower hereby agrees to indemnify and hold Coast harmless with respect
to any loss, cost, expense, or liability incurred by Coast under any Letter of
Credit as a result of Coast's indemnification of any such issuing bank. The
provisions of this Agreement, as it pertains to Letters of Credit, and any other
present or future documents or agreements between Borrower and Coast relating to
Letters of Credit are cumulative.

      Except as expressly modified herein, all other terms and conditions of
Section 1 of the Loan Agreement, as previously modified or amended, remain
unchanged.

================================================================================

SECTION 1 OF THE SCHEDULE (with respect to the Credit Limit) is amended to read
as follows:

1.  CREDIT LIMIT

(Section 1.1):             Loans in a total amount at any time outstanding
                           not to exceed the lesser of a total of $7,000,000
                           (the "Maximum Dollar Amount"), or the sum of (a) and
                           (b) below:
                                (a) Loans (the "Receivable Loans") in an amount
                                    not to exceed 79% of the amount of
                                    Borrower's Eligible Receivables (as defined
                                    in Section 8 above) for the month of April,
                                    1999 and decreasing by 1% per month
                                    thereafter until such time as the advance
                                    rate reaches 75%, at which point the maximum
                                    advance rate shall remain at 75%. The
                                    advance rate on the Receivable Loans may be
                                    increased, in Coast's sole and absolute
                                    discretion, to an amount not to exceed 80%
                                    of Borrower's Eligible Receivables if Coast,
                                    in it sole and absolute discretion,
                                    determines that dilution of Receivables has
                                    been and is, in Coast's opinion, likely to
                                    continue at a rate that is 10% or less, plus

                                (b) Loans (the "Inventory Loans") in an amount
                                    not to exceed the lesser of:

<PAGE>

                                    (1) 30% of the value of Borrower's Eligible
                                    Inventory (as defined in Section 8 above),
                                    calculated at the lower of cost or market
                                    value and determined on a first-in,
                                    first-out basis, or
                                    (2) $1,500,000.00.

                                (c) A Term Loan (the "Equipment Loan") in the
                                    original principal amount of $478,000. The
                                    Equipment Loan will be repayable in 36 equal
                                    monthly installments of principal with the
                                    first principal installment due on May 31,
                                    1999 and continuing on the last day of each
                                    month thereafter. The Equipment Loan is
                                    evidenced by that certain Secured Term Note

                                   (Term Loan)

Borrower:         Osicom Technologies, Inc., a Delaware corporation
                  (formerly known as Cray Communications, Inc.)
Address:          2800 28th Street, Suite 100
                  Santa Monica, California 90405

Date:             April 16, 1999

$478,000                                                 Los Angeles, California

FOR VALUE RECEIVED, the undersigned Borrower promises to pay to the order of
COAST BUSINESS CREDIT(R), a division of Southern Pacific Bank ("Coast"), at
12121 Wilshire Boulevard, Suite 1400, Los Angeles, California, or at any such
other address as the holder of this Secured Term Note (this "Note") shall
direct, the principal sum ("Principal") of Four Hundred Seventy Eight Thousand
Dollars ($478,000.00), plus interest and other charges as hereinafter provided.

      Principal hereunder shall be repaid in equal monthly installments of
Thirteen Thousand Two Hundred Severty Seven Dollars and Seventy Eight Cents
($13,277.78), with the first payment commencing on May 31, 1999 and continuing
on the last day of each month thereafter.

      The unpaid Principal balance together with accrued interest and other
charges shall be fully due and payable on the earlier of (i) the Maturity Date
as provided in Section 6.1 of the Loan and Security Agreement between Borrower
and Coast dated as of September 27, 1996, as amended by the 1st Amendment to
Loan and Security

Agreement of even date herewith (the "Loan Agreement"), (ii) the effective date
of termination as provided in Section 6.2 of the Loan Agreement (the Loan
Agreement and all documents and agreements relating thereto are collectively
referred to as the "Loan Documents") or (iii) February 1, 2002. The automatic
renewal provided in Section 6.1 of the Loan Agreement shall not be applicable to
modify the payment terms of the Principal hereunder.

                                      -1-
<PAGE>

      Interest shall accrue at a rate equal to the "Prime Rate" plus 2.5% per
annum, calculated on the basis of a 360-day year for the actual number of days
elapsed or such different interest rate as provided in the Loan Documents. The
interest rate shall be adjusted monthly as of the first day of each month, and
the interest to be charged for each month shall be based on the highest "Prime
Rate" in effect during said month. Interest shall be payable monthly, on the
last day of the month. "Prime Rate" means the actual "Reference Rate" or the
substitute therefor of Bank of America NT & SA whether or not that rate is the
lowest interest rate charged by said bank. If the Prime Rate, as defined, is
unavailable, "Prime Rate" shall mean the highest of the prime rates published in
the Wall Street Journal on the first business day of the month, as the base rate
on corporate loans at large U.S. money center commercial banks. Interest on this
Note shall be subject to adjustments as provided in Section 1.2 of the Schedule
to the Loan Agreement and Section 7.2 of the Loan Agreement.

      Principal of, and interest on, this Note shall be payable in lawful money
of the United States of America. If a payment hereunder becomes due and payable
on a Saturday, Sunday or legal holiday, the due date thereof shall be extended
to the next succeeding business day, and interest shall be payable thereon
during such extension.

      In the event Borrower fails to pay when due any payment of Principal or
interest on this Note, or if any default or event of default occurs under the
Loan Documents or any other present or future instrument, document, or agreement
between Borrower and Coast, Coast may, at its option, at any time, declare the
entire unpaid Principal balance of this Note plus all accrued interest and other
charges to be immediately due and payable, without notice or demand. The
acceptance of any installment of Principal or interest by Coast after the time
when it becomes due, as herein specified, shall not be held to establish a
custom, or to waive any rights of Coast to enforce payment when due of any
further installments or any other rights, nor shall any failure or delay to
exercise any rights be held to waive the same.

      Borrower agrees to pay an Early Termination Fee in the amount and when
provided in the Loan Agreement.

      All payments hereunder are to be applied first to costs and fees referred
to herein, second to the payment of accrued interest and the remaining balance
to Principal. Any Principal prepayment hereunder shall be applied against
Principal payments in the inverse order of maturity. Coast shall have the
continuing and exclusive right to apply or reverse and reapply any and all
payments hereunder in its sole discretion.

      Borrower agrees to pay all reasonable costs and expenses (including,
without limitation, attorneys' fees and costs) incurred by Coast in connection
with or related to this Note, or its enforcement, whether or not suit be
brought. Borrower hereby further waives presentment, demand for payment, notice
of dishonor, notice of nonpayment, protest, notice of protest, and any and all
other notices and demands in connection with the delivery, acceptance,
performance, default, or enforcement of this Note.

                                      -2-

      This Note is secured by the Collateral (as defined in the Loan Agreement)
and all other present and future security that may be provided by Borrower to
Coast. Nothing herein shall be deemed to limit any of the terms or provisions of
the Loan Documents, or any other present or future document, instrument or
agreement, between Borrower and Coast, and all of Coast's rights and remedies
hereunder and thereunder are cumulative.

      In the event any one or more of the provisions of this Note shall for any
reason be held to be invalid, illegal or unenforceable, the same shall not
affect any other provision of this Note and the remaining provisions of this
Note shall remain in full force and effect.

      No waiver or modification of any of the terms or provisions of this Note
shall be valid or binding unless set forth in a writing signed by a duly
authorized officer of Coast, and then only to the extent therein specifically
set forth.

      COAST AND BORROWER EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY
ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (i)
THIS NOTE; OR (ii) ANY OTHER PRESENT OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN
COAST AND BORROWER; OR (iii) ANY CONDUCT, ACTS OR OMISSIONS OF COAST OR BORROWER
OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER
PERSONS AFFILIATED WITH COAST OR BORROWER.

      Except as otherwise provided in this Note, any dispute, controversy or
claim arising out of or relating to this Note shall be settled by arbitration
pursuant to the arbitration provisions set forth in the Loan Agreement.
