Exhibit 2.1



DESCRIPTION OF SECURITIES

REGISTERED UNDER SECTION 12 OF THE EXCHANGE
ACT



As of March 31, 2020, Sify Technologies
Limited (“we,” “us,” and “our”) had the following series of securities registered pursuant
to Section 12(b) of the Exchange Act:



|Title of each class                                            |  | Trading symbol |  | Name of each Exchange on which
registered
|-------------------------------------------------------------- |  | -------------- |  | -----------------------------------------
|American Depositary Shares, each representing one Equity Share |  | SIFY           |  | NASDAQ Capital Market                    



Our American Depositary
Shares (or “ADSs”), as evidenced by American Depositary Receipts (or “ADRs”), are traded in the United
States on the Nasdaq Capital Market (“NSDAQ”) under the ticker symbol “SIFY.” Each ADS represents one Equity
Share.



The following summary
is subject to and qualified in its entirety by our Memorandum and Articles of Association, as amended, and by Indian law, particularly
the Indian Companies Act, 2013, as amended (the “Companies Act”).



This is not a summary
of all the significant provisions of our Memorandum and Articles of Association, or of Indian law and does not purport to be complete.
We advise that you read our Articles of Association and Memorandum of Association in their entirety as they contain important additional
information that is not included herein.



Item 9.A.3 -If the Company’s
shareholders have pre-emptive purchase rights and where the exercise of the right of 25 pre-emption of shareholders is restricted
or withdrawn, the Company shall indicate the basis for the issue price if the issue is for cash, together with the reasons for
such restriction or withdrawal and the beneficiaries of such restriction or withdrawal if intended to benefit specific persons.



Answer:

Section 62 of the
Companies Act, 2013, contains the provisions on further issues of Capital and enacts the principle of pre-emptive rights of shareholders
of a Company to subscribe to new shares of the Company. However, such rights can be waived and modified as per the provisions of
the Companies Act, 2013.



U.S. investors in
our ADSs may be unable to exercise pre-emptive rights for the shares underlying our ADSs unless a registration statement under
the Securities Act of 1933 is effective with respect to the rights or an exemption from the registration requirements of the Securities
Act is available. Our decision to file a registration statement will depend on the costs and potential liabilities associated with
a registration statement as well as the perceived benefits of enabling U.S. investors in our ADSs to exercise their pre-emptive
rights and any other factors we consider appropriate at the time. We might choose not to file a registration statement under these
circumstances. If we issue any of these securities in the future, such securities may be issued to the Depositary, which may sell
them in the securities markets in India for the benefit of the investors in our ADSs. There can be no assurances as to the value,
if any, the Depositary would receive upon the sale of these securities. If the Depositary determines that the rights could not
be sold, the Depositary might allow such rights to lapse. To the extent that U.S. investors in our ADSs are unable to exercise
pre-emptive rights, their proportional interests in us would be reduced.



Item 9.A.5. Type and class of securities



5 & 5a State the type and class of the
securities being offered or listed and furnish the following information:



Indicate whether the shares are registered
shares or bearer shares and provide the number of shares to be issued and to be made available to the market for each kind of share.
The nominal par or equivalent value should be given on a per share basis and, where applicable, a statement of the minimum offer
price. Describe the coupons attached, if applicable



SHARE CAPITAL



Our Authorized Share Capital is ₹204,00,00,000
(Rupees Two Hundred Four Crores only) divided into 20,40,00,000 (Twenty Crores Forty Lakhs only) Equity Shares, having a par value
of ₹10/- per share.



As of March 31, 2020, 17,92,23,247
Equity Shares / ADS, of par value ₹ 10 per share were issued, outstanding
and fully paid.



1







As of March 31, 2020,
22.15% of our issued and outstanding Equity Shares were held by ADS holders. Our Equity Shares and their holders are registered
in a registry of members. All of our shares have equal voting rights and carry equal entitlements to dividends and bonus issue
of shares, if any.



Under certain circumstances,
the Reserve Bank of India must approve the sale of Equity Shares underlying ADSs by a non-resident of India to a resident of India.
The Reserve Bank of India has given general permission to effect sales of existing shares or convertible debentures of an Indian
Company by a resident to a non-resident, subject to certain conditions, including the price at which the shares must be sold. Additionally,
except under certain limited circumstances, if an investor seeks to convert the Indian rupee proceeds from a sale of Equity Shares
in India into foreign currency and then repatriate that foreign currency from India, he or she will have to obtain an additional
approval from the Reserve Bank of India for each such transaction. Required approval from the Reserve Bank of India or any other
government agency may not be obtained on terms favorable to a non-resident investor or at all.



Investors who exchange
our ADSs for our underlying Equity Shares may be subject to the provisions of the Companies Act and to the disclosure obligations
that may be necessary pursuant to the Deposit Agreement with our Depositary. The Companies Act requires that, where the registered
owner of shares does not hold the beneficial interest in such shares, both the registered owner and the beneficial owner of such
Equity Shares are required to disclose to the Company the nature of their interest, particulars of the registered owner and certain
other details.



(b) Restrictions on transfer



Foreign investment
in Indian securities, whether in the form of foreign direct investment or in the form of portfolio investment, is governed by the
Foreign Exchange Management Act, 1999, as amended (“FEMA”), and the rules, regulations and notifications issued thereunder.
Set forth below is a summary of the restrictions on transfers applicable to both foreign direct investments and portfolio investments,
including the requirements under Indian law applicable to the issuance and transfer of ADSs.



Ownership restrictions



In terms of Master
Circular issued in April 2014, in most manufacturing / service sectors do not require prior approval of the FIPB/DIPP, or the RBI,
if the activity of the investee-Company fulfill the conditions prescribed for Automatic Route. These conditions include certain
eligibility norms, pricing requirements, subscription in foreign exchange, compliance with the Takeover Code (as described below),
and ownership restrictions based on the nature of the foreign investor (as described below). Purchases by foreign investors of
ADSs are treated as direct foreign investment in the equity issued by Indian companies for such offerings. Foreign investment up
to 100 % of our share capital is currently permitted in telecom industry.



The Foreign Exchange
Management (Non-Debt Instruments) Rules, 2019 (the "NDI Rules") has brought about a substantial change in the Schedule
II to the NDI Rules, stating that effective as of April 1, 2020, the aggregate limit would be the sectoral cap applicable to such
Indian Company. An Indian Company may, with the approval by Resolution of its Board of Directors and by Special Resolution of its
members: (i) decrease the aggregate limit before March 31, 2020 to a lower threshold of 24%, 49% or 74%, as it deems fit, or (ii)
increase the aggregate limit to 49% or 74%, or the sectoral cap or statutory ceiling, as it deems fit. However, once the aggregate
limit is increased, the limit cannot be reduced later.



If a FPI’s investments
exceed the prescribed limits, the FPI will have the option to divest its excess holdings within 5 trading days, failing which the
entire investment in the Company will be considered a Foreign Direct Investment (“FDI”). If the investment falls under
a category where FDI is prohibited, the aggregate FPI limit is capped at 24%.



No single FPI may
hold more than 10.0% of the shares of an Indian Company and no single NRI may hold more than 5.0% of the shares of an Indian Company.
If multiple entities have at least 50% overlap in their ownership (direct or ultimate beneficial owners), then such entities shall
be treated as part of the same group and the above percentage of FPI investment limit shall apply to the entire group as if they
were a single FPI.

Subsequent transfer
of shares



A person resident
outside India holding the Shares or Debentures of an Indian Company may transfer the equity instruments held by him, in compliance
with the conditions specified in the Foreign Exchange Management (Non-Debt Instruments) Rules, 2019 ("NDI Rules"), as
follows:



| | (i) | A person resident outside India who is not a NRI, an overseas citizen of India or a former Overseas Corporate Body (“OCB”), may transfer by way of sale or gift, the equity instruments held by him to any person resident outside India;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | A NRI may transfer by way of sale or gift, the equity instruments held by that person to another NRI or to any person resident outside India; or
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | A person resident outside India holding the equity instruments of an Indian Company in accordance with the NDI Rules, (a) may transfer such equity instrument to a person resident in India by way of sale or gift; or (b) may sell such equity instrument on a recognized Stock Exchange in India through a registered broker.
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



In enacting the NDI
Rules, the Central Government superseded the Foreign Exchange Management (Transfer or Issue of Securities by a person Resident
Outside India) Regulations, 2017.



The NDI Rules give
the readers a consolidated view of the transfer or issue of securities by a person resident outside India and also clarifies several
aspects of FDI. These regulations aim towards further simplification and provide greater clarity on differentiation between FDI
and FPI.



ADS guidelines



Shares of Indian companies
represented by ADSs may be approved for issuance to foreign investors by the Government of India under the Issue of Foreign Currency
Convertible Bonds and Ordinary Shares (Through Depositary Receipt Mechanism) Scheme, 1993 (the “1993 Scheme”), as modified
from time to time, promulgated by the Government of India. The 1993 Scheme is in addition but without prejudice to the other policies
or facilities, as described below, relating to investments in Indian companies by foreign investors. The issuance of ADSs pursuant
to the 1993 Scheme also affords to holders of the ADSs the benefits of Section 115AC of the Income Tax Act, 1961 for purpose of
the application of Indian tax laws. In March 2001, the RBI issued a notification permitting, subject to certain conditions, two-way
fungibility of ADSs. This notification provides that ADSs converted into Indian shares can be converted back into ADSs, subject
to compliance with certain requirements and the limits of sectorial caps.



The Ministry of Finance,
Government of India, enacted The Depository Receipts Scheme, 2014 (the “Depository Receipts Scheme”) effective as of
December 15, 2014. In order to facilitate the issuance of depository receipts by Indian companies outside India, the Depository
Receipts Scheme repeals the former provisions dealing with depository receipts in the Foreign Currency Convertible Bonds and Ordinary
Shares (Through Depositary Receipt Mechanism) Scheme, 1993. The Depository Receipts Scheme now governs the issue or transfer of
permissible securities to a foreign depository by eligible persons and defines the rights and duties of a foreign depository and
obligations of a domestic custodian.



There are certain
relaxations provided under the Depository Receipts Scheme subject to prior approval of the Ministry of Finance. For example, a
registered broker is permitted to purchase shares of an Indian Company on behalf of a person resident outside of India for the
purpose of converting those shares into ADSs. However, such conversion is subject to compliance with the provisions of the Depository
Receipts Scheme and the periodic guidelines issued by the regulatory authorities. Therefore depository receipts converted into
Indian shares may be converted back into depository receipts, subject to certain limits of sectorial caps.



Under the Depository
Receipts Scheme, a foreign depository may take instructions from depository receipts holders to exercise the voting rights with
respect to the underlying equity securities. Additionally, a domestic custodian has been defined to include a custodian of securities,
an Indian depository, a depository participant or a bank having permission from SEBI to provide services as custodian. Further,
the Depository Receipts Scheme provides that the aggregate of permissible securities which may be issued or transferred to foreign
depositories for issue of depository receipts, along with permissible securities already held by persons resident outside India,
shall not exceed the limit on foreign holding of such permissible securities under the Foreign Exchange Management Act, 1999.



3







The Department of
Economic Affairs, Ministry of Finance made amendments to certain provisions of the Securities Contracts (Regulation) Rules, 1957
pursuant to Securities Contracts (Regulation) (Amendment) Rules, 2015, on February 25, 2015. An amended, the “public shareholding”
for our Equity Shares held by the public includes shares underlying depository receipts if the holder of such depository receipts
has the right to issue voting instruction and such depository receipts are listed on an international stock exchange in accordance
with the Depository Receipts Scheme.



Fungibility of
ADSs



A registered broker
in India can purchase shares of an Indian Company that issued ADSs, on behalf of a person residing outside India, for the purposes
of converting the shares into ADSs.



The Depository Receipts
Scheme states that the aggregate of permissible securities which may be issued or transferred to foreign depositories for issue
of depository receipts, along with permissible securities already held by persons resident outside lndia, shall not exceed the
limit on foreign holding of such permissible securities under the Foreign Exchange Management Act, 1999.



A limited two-way
fungibility scheme has been put in place by the Government of India for ADRs / GDRs. Under this Scheme, a stock broker in India,
registered with SEBI, can purchase shares of an Indian Company from the market for conversion into ADRs/GDRs based on instructions
received from overseas investors. Re-issuance of ADRs / GDRs would be permitted to the extent of ADRs / GDRs which have been redeemed
into underlying shares and sold in the Indian market.



Currently, there is
no public trading market for our equity shares in India or elsewhere nor can we assure you that we will take steps to develop one.
Our equity securities are only traded on NASDAQ through the ADSs as described in this report. Under prior Indian laws and regulations,
our Depository could not accept deposits of outstanding equity shares and issue ADRs evidencing ADSs representing such equity shares
without prior approval of the Government of India. The Reserve Bank of India has announced fungibility regulations permitting,
under limited circumstances, the conversion of ADSs to equity shares and the reconversion of equity shares to ADSs provided that
the actual number of ADSs outstanding after such reconversion is not greater than the original number of ADSs outstanding. If you
elect to surrender your ADSs and receive equity shares, you will not be able to trade those equity shares on any securities market
and, under present law, likely will not be permitted to reconvert those equity shares to ADSs.



If in the future a
market for our equity shares is established in India or another market outside of the United States, those shares may trade at
a discount or premium to the ADSs. Under current Indian regulations and practice, the approval of the Reserve Bank of India is
not required for the sale of equity shares underlying ADSs by a non-resident Indian to a resident Indian as well as for renunciation
of rights to a resident of India, unless the sale of equity shares underlying the ADSs is through a recognized stock exchange or
in connection with the offer made under the regulations regarding takeovers. The shareholders who intend transferring their equity
shares shall comply with the procedural requirements set out under the head ‘subsequent transfers’ above.



Transfer of ADSs



A person resident
outside India may transfer the ADSs held in Indian companies to another person resident outside India without any permission. An
ADS holder is permitted to surrender the ADSs held by him in an Indian Company and to receive the underlying equity shares under
the terms of the Deposit Agreement. Under Indian regulations, the re-deposit of these equity shares with the Depository for ADSs
may not be permitted.



Shareholders resident
outside India who intend to sell or otherwise transfer Equity Shares within India should seek the advice of Indian counsel to understand
the requirements applicable at that time.



Question: 9.A.6.If the rights
evidenced by the securities being offered or listed are or may be materially limited or qualified by the rights evidenced by any
other class of securities or by the provisions of any contract or other documents, include information regarding such limitation
or qualification and its effect on the rights evidenced by the securities to be listed or offered.



Not applicable.



Question: 9.A.7. Securities other
than Equity Shares

Item 10.B. Memorandum and articles
of association



10. B.3. Shareholder rights



| | (a) | Dividend rights.
| | --- | ----------------



Our Board of directors
recommends the payment of dividend which is then declared by our shareholders in a General Meeting. However, the Board is not obliged
to recommend a dividend. Similarly, under our Articles of Association and the Companies Act, our shareholders may, at the Annual
General Meeting, declare a dividend in an amount less than that recommended by the board of directors, but they cannot increase
the amount of the dividend. The dividend declared by the shareholders, if any, is required to be distributed and paid to shareholders
in proportion to the paid up value of their shares within 30 days of the declaration by the shareholders at the Annual General
Meeting. Pursuant to our Articles of Association, our Board of Directors has discretion to declare and pay interim dividends without
shareholder approval.



Under the Companies
Act, 2013 and rules made thereunder, dividends may be paid out of profits of a Company in that financial year in which the dividend
is declared after providing for depreciation or out of the undistributed profits of previous fiscal years after providing for depreciation.
Before declaring any dividend in any financial year, Company may transfer a percentage of its profits which it considers appropriate
to its reserves. The Companies Act, 2013 further provides that in case of an inadequacy or absence of profits in any year, a maximum
of 10% of paid-up capital can be declared as dividend, subject to other provisions contained in the Companies (Declaration and
Payment of Dividend) Rules, 2014.



The Companies Act,
2013 provides that any dividends that remain unpaid or unclaimed after a period of 30 days from the date of their declaration are
to be transferred to a special bank account opened by the Company at an approved bank. We transfer any dividends that remain unpaid
or unclaimed within 7 days from the date of expiration of such 30 days period to such account. If any amount in this account has
not been claimed by the eligible shareholders within seven years from the date of the transfer, we transfer the unclaimed dividends
to an Investor Education and Protection Fund established by the Government of India under the provisions of the Companies Act,
2013.



| | (b) | Voting rights.
| | --- | --------------



All of our Equity
Shares have the same voting rights. For all matters submitted to vote in a shareholders meeting of the Company, every holder of
an equity share, as reflected in the records of the Company as on the record date set for the shareholders meeting, shall have
one vote in respect of each share held. There are no cumulative voting rights. If you are an ADR holder and the Depositary asks
you to provide it with voting instructions, you may instruct the Depositary how to exercise the voting rights for the shares which
underlie your ADSs. After receiving voting materials from us, the Depositary will notify the ADR holders of any shareholder meeting
or solicitation of consents or proxies. This notice will describe how you may instruct the Depositary to exercise the voting rights
for the shares which underlie your ADSs. For instructions to be valid, the Depositary must receive them on or before the date specified.
The Depositary will try, as far as is practical, subject to the provisions of and governing the underlying shares or other deposited
securities, to vote or to have its agents vote the shares or other deposited securities as you instruct. The Depositary will only
vote or attempt to vote as you instruct. The Depositary will not itself exercise any voting discretion. Neither the Depositary
nor its agents are responsible for any failure to carry out any voting instructions, for the manner in which any vote is cast or
for the effect of any vote.



| | (c) | Rights to share in our profits.
| | --- | -------------------------------



See “Dividend
Rights” in subsection (a) above.



| | (d) | Rights to share in any surplus in the event of our liquidation.
| | --- | ---------------------------------------------------------------



As per the Companies
Act, 2013 and the Insolvency and Bankruptcy Code, 2016, certain payments have preference over payments to be made to equity shareholders.
These payments having preference include payments to be made by us to our employees, taxes, payments to secured and unsecured lenders
and payments to holders of any shares entitled by their terms to preferential repayment over the Equity Shares.



In the event of our
Company’s liquidation, all preferential amounts, if any, shall be discharged by us. Our remaining assets shall be distributed
to the holders of Equity Shares based upon the proportion of the number of shares held to the total Equity Shares outstanding as
on that date.

| | --- | ----------------------



Not applicable.



| | (f) | Sinking fund provisions.
| | --- | ------------------------



Not applicable.



| | (g) | Liability to further capital calls by us.
| | --- | -----------------------------------------



Although our Memorandum
and articles of association do provide for certain capital call obligations in respect of any monies unpaid on the shares of a
shareholder, all of our issued and outstanding shares have been fully paid in. Accordingly, our shareholders are not obliged to
make further contributions with respect to their shares.



| | (h) | Any provision discriminating against any existing or prospective holder of such securities as a result of such shareholder owning a substantial number of shares.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



No such provisions
are applicable under our Memorandum and articles of association. However, for a summary of the restrictions under the Securities
and Exchange Board of India (Substantial Acquisition of Shares and Takeovers) Regulations, 2011 (the “2011 Takeover Code”),
see item 9.A.5. “Type and class of securities” set forth above.



10.B.4. Changes to shareholder rights



Currently, only one
class of Equity Shares is authorized and outstanding under our Memorandum and articles of association. However, if at any time
the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the
terms of issue of the shares of that class) may be varied with the consent in writing of the holders of such proportion of the
issued shares of that class as maybe specified in the Companies Act or rules made thereunder, or with the sanction of a special
resolution passed at a separate meeting of the holders of the shares of that class. If a capital increase is approved, then our
shareholders would generally have certain pre-emptive rights as described above.



10.B.6. Limitations on rights to
own securities



No limitations on
the rights to own securities are applicable under our memorandum and articles of association. However, for a summary of the restrictions
on transfers applicable to both foreign direct investments and portfolio investments, including the requirements under Indian law
applicable to the issuance and transfer of ADSs, see item 9.A.5. “Type and class of securities” set forth above.



10.B.7 Change in control



No provisions that
would have an effect of delaying, deferring or preventing a change in control of the Company are applicable under our Memorandum
and articles of association. However, for a summary of the restrictions under the Securities and Exchange Board of India (Substantial
Acquisition of Shares and Takeovers) Regulations, 2011, see item 9.A.5. “Type and class of securities” set forth above.



10.B.8 Disclosure of shareholdings



The Companies Act
requires that, where the registered owner of shares does not hold the beneficial interest in such shares, both the registered owner
and the beneficial owner of such Equity Shares are required to disclose to the Company the nature of their interest, particulars
of the registered owner and certain other details.



10.B.9 Differences in the law



See the references
to Indian law throughout this “Item 10.B Memorandum and articles of association.”



10.B.10 Changes in capital



The requirements of
the memorandum and articles of association regarding changes in capital are not more stringent than the requirements of Indian
law.

Not applicable.



12.D American Depositary Shares



Citibank, N.A. located at 388 Greenwich

Each of our American
Depositary Shares (or “ADSs”), as evidenced by American Depositary Receipts (or “ADRs”), represents one

in the Deposit Agreement (such as the rights to vote, to receive a dividend and to receive an equity share of our Company in exchange
for a certain number of ADRs). Only the Depositary is registered as shareholder in our share register. An ADR is not an equity
share and an ADR holder is not a shareholder of our Company.
